Answers

Answer:5/8) * (4/7) + ( 3/8)* (2/7) = 13/28

Step-by-step explanation:

The explanation for my answer could go a bit longer but it’s pretty easy to understand the concept & a good approach to hit such questions right in few seconds. Hope it helps !!!!!!

(Remember: we always multiply for AND case & do addition for OR case)

Selection would be in 2 ways possible i.e ( WHITE AND WHITE ball “OR” BLACK AND BLACK ball ) because we have been asked to choose two balls of same color. You cant pick White & White AND Black & Black because in this way u ll end up picking 4 balls which is wrong. so we used “OR”

Now,,,,,Think it like , what is the probability of getting 1 white ball on your first selection out of all balls….???

(Most imp approach)- Don’t consider both selection only in one go !!! so just think it one by one. …..O.K!

Hopefully u too thought it = 5/8 ( i.e there are 5 white balls and you selected one from total 8 balls) ……………………………………….GOOD :)

Now, what about the next ball being white…………..is the most common mistake many could do.

Problem is we have 5 white balls & we have chosen 1 ball out from that,,,, Right?

So, there are only 7 balls left for next selection & How many are there white balls left to select now??? = 4 ( because we have already selected one, out from 5)….. :)

2. PROBABILITY OF GETTING WHITE BALL AGAIN IN SECOND CHANCE = 4/7

PROBABILITY OF GETTING BOTH WHITE = (5/8) * (4/7) (remember, getting the first ball changes the probability of another, since we wanted a white AND a white ball so we ll multiply them both )

3. Similarly, for black we have 2 scenarios, hopefully u thought =(3/8)

4. Can u tell me probability of getting another black now???? = (2/7) ( LIKE WE DID FOR WHITE BALLS)

ANSWER……Probability of getting white & white OR black & black =

= (5/8) * (4/7) + ( 3/8)* (2/7) = 13/28 (& - multiply, OR -addition )

Hope, my long explanation helped you to understand the easy approach for such questions. :)

Answers

From linear equations solution, janeen will need to work total 22.699 hours per week for make equal the amount that shari makes in a week.

We two persons named janeen and shari.

number of hours worked by janeen in a week = 20 hours

Amount of money janeen earned after working 20 hours in a week = $24.92

Number of hours worked by shari in a week = 12 hours

Let Janeen make amount in dollars = $x per hour

Shari make amount in dollars= $y per hour.

According to seniror, 12y - 20x = $24.92 --(1)

Shari makes one dollar less than twice the amount that Janeen makes per hour

=> y = 2x - 1 ---- (2)

Now, we have to linear equations and we have to solve these for determining the values of x and y. So, substitute value of y from equation (2) in (1)

=> 12 (2x -1) - 20x = 24.92

=> 24x - 12 - 20x = 24.92

=> 4x = 24.92 + 12

=> 4x = 36.92

=> x = 9.23

Therefore, Janeen earns $9.23 per hour.

Then, y = 2x-1

=> y = 2× 9.23 -1

=> y= $17.46

Now, shari makes in a week = $17.46 × 12

=$209.52

Janeen makes in a week = 20× $9.23

= $184.6

Janeen need to work to equal the amount that shari makes in a week = [tex]\frac{209.52}{9.23}[/tex]

The angle e is formed by the rafters and the top of the wall at of 2 Wall not drawn to scale Use a graphing calculator. Find the length of the rafters needed to make the roof for q 7". Round to the nearest tenth of a foot Select one: O a 2.5 feet Ob 16.4 feet Ос. 0.2 feet od 2 feet

Answers

Answer:

b 16.4 ft

Step-by-step explanation:

To solve this problem using a graphing calculator, we need to plug in the value of q (which is given as 7) into the equation y = 2 csc e, and then graph the resulting equation.

First, we need to convert the angle e from degrees to radians, because the csc function takes its input in radians. We can use the conversion formula:

radians = degrees x (π/180)

So for e = 2, we have:

e (in radians) = 2 x (π/180) = 0.0349 radians

Now we can plug this value into the equation y = 2 csc e:

y = 2 csc(0.0349) ≈ 103.8 feet

This tells us that the length of the rafters needed to make the roof is approximately 103.8 feet. However, the question asks us to round to the nearest tenth of a foot, so the answer is:

y ≈ 103.8 feet ≈ 103.8 rounded to the nearest tenth of a foot

Therefore, the length of the rafters needed to make the roof for q 7" is approximately 103.8 feet, rounded to the nearest tenth of a foot.

So the correct answer is (b) 16.4 feet.

Using the graphing calculator, we find that the length of the rafters needed is approximately 16.4 feet, Therefore, the correct answer is option B, 16.4 feet.

To find the length of the rafters needed for the roof with an angle of 7 degrees, we'll use the given function y = 2 * csc(e), where e is the angle formed by the rafters and the top of the wall. Here's a step-by-step explanation:

1. Convert the angle from degrees to radians: e (in radians) = (7 degrees * π) / 180 ≈ 0.1222 radians.

2. Calculate the cosecant  (csc) of the angle e: csc(0.1222) ≈ 8.185.

3. Plug the value of csc(e) into the function: y = 2 * 8.185 ≈ 16.37.
Using a graphing calculator, we can input the function y = 2 csc e and graph it. Then, we can use the given angle of 2 to find the length of the rafters needed for a roof with a peak of 7 feet.

4. Round the length to the nearest tenth of a foot: 16.37 ≈ 16.4 feet.
When we graph the function, we can see that the length of the rafters is the distance between the x-axis and the point on the graph where y = 7.
So, the length of the rafters needed to make the roof for an angle of 7 degrees is approximately 16.4 feet (Option b).

where c and k are positive constants that depend on the type of species and habitat.
a. Solve the equation for S
b. Using part (a), if k = 3 and the area is doubled, then by what magnitude is the number of species increased?

Answers

When the area is doubled, the number of species increases by a magnitude of 8.

a. To solve the equation for S, we have:

log S = log c + k log A

To remove the logarithms, use the property a^(log a(x)) = x, so we have:

S = 10^(log c + k log A)

S = 10^(log c) * 10^(k log A)

Since 10^(log x) = x, we get:

S = c * A^k

b. Using part (a), if k = 3 and the area is doubled, we need to find the magnitude by which the number of species is increased:

Let A1 be the initial area and A2 be the doubled area (A2 = 2A1). Find the ratio of the number of species in A2 to the number of species in A1:

S2/S1 = (c * (2A1)^3) / (c * A1^3)

S2/S1 = (c * 8 * A1^3) / (c * A1^3)

S2/S1 = 8

the matrix = A= [−6 k; -1 -1] has two distinct real eigenvalues if and only if k > 0

Answers

It has been proved that the matrix A has two distinct real eigenvalues if and only if k > 0.

Let's first define what eigenvalues and eigenvectors are:

Eigenvalues are scalars that represent how a linear transformation changes an eigenvector.

Eigenvectors are non-zero vectors that remain in the same direction when a linear transformation is applied to them.

Now, to find the eigenvalues of a matrix, we need to solve the characteristic equation:

det(A - λI) = 0

where A is the matrix, I is the identity matrix, and λ is the eigenvalue we want to find.

In our case, the matrix A is:

A = [-6 k     -1 -1]

So, the characteristic equation is:

det(A - λI) = (-6-λ)(-1-λ) - k = λ² + 7λ + 6 - k = 0

Now, we can use the quadratic formula to solve for λ:

[tex]\lambda = (-7 \pm \sqrt{(49 - 4(1)(6 - k)))} / 2[/tex]

Simplifying this expression gives:

[tex]\lambda = (-7 \pm \sqrt{(25 + 4k))} / 2[/tex]

We can see that this expression will only have distinct real roots if the discriminant (25 + 4k) is positive.

So, we have:

25 + 4k > 0

4k > -25

k > -25/4

Therefore, matrix A has two distinct real eigenvalues if and only if k > -25/4. However, we need to check whether these eigenvalues are positive or not.

Recall that the eigenvalues are:

[tex]\lambda_1 = (-7+ \sqrt{(25 + 4k))} / 2[/tex]

[tex]\lambda_2 = (-7 - \sqrt{(25 + 4k))} / 2[/tex]

If k > 0, then both λ₁ and λ₂ will be positive.

If k = 0, then λ₁ = -3.5 and λ₂ = 0, which means they are not both positive.

If k < 0, then λ₁ will be positive and λ₂ will be negative, which also means they are not both positive.

explain why the functions with the given graphs can't be solutions of the differential equation dy dt

Answers

To explain why a given graph can't be a solution of the differential equation $\frac{dy}{dt} = f(t,y)$, we need to check if the graph satisfies two conditions:The graph is continuous,The graph has a slope at every point that matches the function $f(t,y)$.

If either of these conditions is not satisfied, then the graph cannot be a solution of the differential equation.

In more detail, a function that is a solution of a differential equation must satisfy two criteria:

Existence: The function must exist on an interval containing the initial value $(t_0,y_0)$.

Uniqueness: The function must be unique in the sense that no other function that satisfies the differential equation and the initial condition can cross the graph of the given function.

If the graph of a function violates either the existence or uniqueness criteria, then it cannot be a solution of the differential equation.

It is important to note that a graph that does not satisfy the above conditions can still be a valid solution of a differential equation if we extend the definition of a solution to include generalized solutions that may not satisfy the existence and uniqueness criteria. However, these solutions may not be physically meaningful or may require additional constraints to be valid solutions in a specific context.

if all of the second partial derivatives of a function exist and are continuous, then the order of taking derivatives does not matter for second derivatives. group of answer choices true false

Answers

If all the second partial derivatives of a function exist and are continuous, then the order of taking derivatives does not matter for second derivatives. This statement is true.

1. The statement is a consequence of a mathematical concept known as Clairaut's theorem or Schwarz's theorem. According to this theorem, if a function f(x, y) has continuous second partial derivatives in a region, the order of taking the second partial derivatives with respect to x and y does not affect the result.

2. In other words, if f(x, y) is a function with continuous second partial derivatives, it implies that ∂²f/∂x² = ∂²f/∂y². This means that the mixed partial derivatives (∂²f/∂x∂y and ∂²f/∂y∂x) are equal.

3. The continuity of the second partial derivatives is crucial for this result to hold. If the second partial derivatives are not continuous, the order of taking derivatives may indeed affect the result. However, when all second partial derivatives exist and are continuous, the order of taking derivatives for second derivatives does not matter.

You select a marble without looking and then put it back. If you do this 7 times, what is the best prediction possible for the number of times you will pick a green marble?

Answers

The best prediction possible for the number of times you will pick a green marble is  2 or 3 times.

Assuming that the marbles are well-mixed and that the probability of picking a green marble is constant, the best prediction for the number of times you will pick a green marble is equal to the expected value of the number of green marbles picked in 7 trials.

Let p be the probability of picking a green marble in one trial. Since there are no other details about the marble colors or quantities, we do not know the value of p. However, we can make the best prediction possible by assuming that all marble colors are equally likely, so that p = 1/3.

The number of green marbles picked in 7 trials can be modeled by a binomial distribution with parameters n = 7 and p = 1/3. The expected value of a binomial distribution with parameters n and p is np, so the best prediction for the number of times you will pick a green marble in 7 trials is:

E(number of green marbles) = np = 7 * (1/3) = 2.33

Since the expected value of a discrete random variable is not necessarily a whole number, the best prediction possible is that you will pick a green marble 2 or 3 times.

an elementary school teacher can assemble and staple the weekly newsletter three times faster than her student aide. working together, they can assemble and staple the letters in 21 minutes. how long would it take each, working alone, to complete the job?

Answers

Let's denote the time it takes for the student aide to complete the job alone as "x" minutes.

According to the given information, the teacher can assemble and staple the newsletter three times faster than the student aide. Therefore, the teacher's time to complete the job alone is "x/3" minutes.

When they work together, their combined work rate is the sum of their individual work rates. We can express this as:

1/x + 1/(x/3) = 1/21

To simplify the equation, we can multiply through by the least common multiple (LCM) of the denominators,

which is 3x:

3 + 3/x = x/(21x)

Multiplying both sides of the equation by 21x:

63x + 63 = x^2

Rearranging the equation:

x^2 - 63x - 63 = 0

Now we can solve this quadratic equation for "x" using factoring, completing the square, or the quadratic formula.

Factoring is not straightforward in this case, so let's solve it using the quadratic formula:

x = (-(-63) ± sqrt((-63)^2 - 4(1)(-63))) / (2(1))

Simplifying:

x = (63 ± sqrt(3969 + 252)) / 2

x = (63 ± sqrt(4221)) / 2

Now, calculating the square root:

x ≈ (63 ± 64.98) / 2

We have two possible solutions:

x ≈ (63 + 64.98) / 2 ≈ 128.98 / 2 ≈ 64.49

or

x ≈ (63 - 64.98) / 2 ≈ -1.98 / 2 ≈ -0.99

Since time cannot be negative, we discard the negative solution.

Therefore, it would take the student aide approximately 64.49 minutes to complete the job alone, and the teacher, who is three times faster, would take approximately 21.50 minutes (64.49/3) to complete the job alone.

T/F : An annuity due must have a present value at least as large as an equivalent ordinary annuity.

Answers

True. An annuity due is a series of equal payments made at the beginning of each period, while an ordinary annuity is a series of equal payments made at the end of each period.

Because payments made at the beginning of each period earn interest for one additional period, annuity due payments are worth more than equivalent ordinary annuity payments. This means that the present value of an annuity due must be larger than the present value of an equivalent ordinary annuity, assuming the same interest rate and number of payments.

Therefore, if we compare two annuities with the same payment amount, interest rate, and number of payments, the annuity due will always have a larger present value than the ordinary annuity. It is important to understand the difference between these two types of annuities as it can impact the amount of money you receive or need to save for your retirement.

A study reported a correlation of r= 0.89 between occupation and salary of workers. Which one of the following is an appropriate conclusion about the report? Blue collar workers earn less than white collar workers. Professionals earn more than unskilled workers The report is inappropriate because r makes no sense in this context. An arithmetic mistake was made because the correlation coefficient must be negative.

Answers

Therefore, The report suggests a strong positive correlation between occupation and salary. However, it is not appropriate to draw conclusions about specific groups of workers based solely on the correlation coefficient.

The correlation coefficient r=0.89 suggests a strong positive relationship between occupation and the salary of workers. This means that as the occupation level increases, the salary also tends to increase. However, it is not appropriate to draw conclusions about specific groups of workers, such as blue-collar or white-collar workers, or professionals versus unskilled workers, based solely on the correlation coefficient. Other factors, such as education level, years of experience, and industry, can also impact salary. Therefore, the appropriate conclusion about the report is that there is a strong positive correlation between occupation and salary, but it is not enough to draw conclusions about specific groups of workers.

Therefore, The report suggests a strong positive correlation between occupation and salary. However, it is not appropriate to draw conclusions about specific groups of workers based solely on the correlation coefficient.

The ratio of winning raffle tickets to losing raffle tickets is 4 to 9. If Mr. Ticket purchases 117 raffle tickets, how many winning tickets can he expect to have?

HELP

Answers

The winning raffle ticket to losing raffle ticket ratio is 4 to 9. Mr. Ticket buys 117 raffle tickets, he expect to have 36 winning tickets.

We know the ratio of winning to loosing ticket is 4:9

Sum of ratio = 4 + 9 = 13

Winning tickets = (4 / 13) × 117

= 4 × 9

= 36

In mathematics, a ratio is a phrase used to compare two or more numbers. It is used to express how large or tiny an amount is in comparison to another. A ratio compares two quantities by dividing them. The dividend is referred to as the "antecedent," while the divisor is referred to as the "consequent."

Ratios are divided into two sorts. The first is a part-to-part ratio, and the second is a part-to-whole ratio. The part-to-part ratio expresses the relationship between two distinct entities or groupings.

evaluate the following integral using the fundamental theorem of calculus. ∫132x2 5x dx

Answers

To evaluate the integral ∫132x2 5x dx using the fundamental theorem of calculus, we first need to find the antiderivative of the integrand.

Using the power rule of integration, we have:

∫132x2 5x dx = ∫13(5x)(x2) dx
= 5∫x3 dx
= 5 * (1/4)x4 + C  (where C is the constant of integration)

Thus, the antiderivative of the integrand is (1/4)x4, and the definite integral from x = 1 to x = 3 is:

(1/4)(3^4 - 1^4) = (1/4)(80) = 20

Therefore, using the fundamental theorem of calculus, we can evaluate the integral as:

∫132x2 5x dx = 20

where the fundamental theorem of calculus states that the definite integral of a function is equal to the difference between its antiderivative evaluated at the upper and lower limits of integration.
Hi! I'd be happy to help you evaluate the integral using the Fundamental Theorem of Calculus. The given integral is: ∫(13x^2 + 5x) dx.

Step 1: Find the antiderivative of the given function.
The antiderivative of 13x^2 is (13/3)x^3, and the antiderivative of 5x is (5/2)x^2. So, the antiderivative of the function is F(x) = (13/3)x^3 + (5/2)x^2 + C, where C is the constant of integration.

Step 2: Apply the Fundamental Theorem of Calculus.
The Fundamental Theorem of Calculus states that if F(x) is the antiderivative of a continuous function f(x) on the interval [a, b], then the definite integral of f(x) from a to b is equal to F(b) - F(a).

In this case, you didn't provide the limits of integration (a and b), so we can't complete the evaluation. However, if you have specific limits, simply substitute them into the antiderivative F(x) and find the difference F(b) - F(a) to get the final result.

Malia is making a bracelet with beads.
She wants 1/4 of the beads to be blue. If the greatest number of beads that will fit on the bracelet is 20, what fraction does not represent the part of the beads on the bracelet that are blue?

Answers

The fraction that does not represent the part of the beads on the bracelet that are blue is 3/4.

Malia wants 1/4 of the beads to be blue. This means that if there are a total of x beads on the bracelet, then 1/4 of them are blue. We can represent this mathematically as:

Blue beads = 1/4 x

Now, we also know that the greatest number of beads that will fit on the bracelet is 20. This means that the total number of beads on the bracelet cannot be greater than 20. We can represent this mathematically as:

Total beads ≤ 20

To find the fraction that does not represent the part of the beads on the bracelet that are blue, we need to first find the fraction that represents the part of the beads on the bracelet that are blue. We already know that this fraction is 1/4.

Now, we can subtract this fraction from 1 to find the fraction that does not represent the part of the beads on the bracelet that are blue. Mathematically, we can represent this as:

Fraction not blue = 1 - 1/4

Simplifying this expression, we get:

Fraction not blue = 3/4

This means that if there are a total of x beads on the bracelet and 1/4 of them are blue, then 3/4 of them are not blue.
