Find all missing angles

Answers

Answer 1

Answer:

m<1 = 51 degrees

m<2 = 18 degrees

m<3 = 123 degrees

m<4 = 39 degrees

Step-by-step explanation:

To solve this problem, let's first try to find the measure of angle 1.

To do this, we must remember that the sum of the interior angles of a triangle must equal 180 degrees. Using this knowledge, we can set up the following equation:

72 + 57 + m<1 = 180

Our first step in solving this equation is to simplify the left side by adding together the two constant terms.

129 + m<1 = 180

Next, we can subtract 129 from both sides of the equation.

m<1 = 51 degrees

Now, we can solve for angle 2.

We can see that angle 2 and the angle measuring 72 degrees together make a right angle, which is 90 degrees. From this observation, we can set up the following equation:

m<2 + 72 = 90

To solve, we subtract 72 from both sides of the equation.

m<2 = 18 degrees

Now, we can solve for angle 3.

We can see from the diagram that angle 3 and the angle measuring 57 degrees are supplementary. This means that their sum should equal 180 degrees, and the two angles together make a straight line. This lets us set up the following equation:

m<3 + 57 = 180

To solve, we subtract 57 from both sides of the equation.

m<3 = 123 degrees

Finally, we can solve for angle 4.

We can solve for angle 4 using the same strategy we used to solve for angle 1. Our equation for angle 4 is as follows:

m<2 + m<3 + m<4 = 180

18 + 123 + m<4 = 180

Let's first simplify the left side of the equation.

141 + m<4 = 180

We can subtract 141 from both sides of the equation as our next step.

m<4 = 39 degrees

Therefore, the correct answers are m<1 = 51 degrees, m<2 = 18 degrees, m<3 = 123 degrees, and m<4 = 39 degrees.

Hope this helps!

Find the surface area of this rectangular prism. Be sure to include the correct unit in your answer.

Answers

Answer: 258 [tex]yard^{2}[/tex]

Step-by-step explanation: To find the surface area you add the area of all the sides. And the unit for a surface area is unit (yards) squared.

Front: 5 • 9 = 45

Back: 5 • 9 = 45

Left: 6 • 5 = 30

Right: 6 • 5 = 30

Top: 9 • 6 = 54

Bottom: 9 • 6 = 54

45 + 45 + 30 + 30 + 54 + 54 = 258.

A and B will take the same 10-question examination. Each question will be answered correctly by A with probability .7, independently of her results on other questions. Each question will be answered correctly by B with probability .4, independently both of her results on the other questions and on the performance of A. (a) Find the expected number of questions that are answered correctly by both A and B. (b) Find the variance of the number of questions that are answered correctly by either A or B.

Answers

(a) The expected number of questions answered correctly by both A and B is 28.

(b) The variance of the number of questions answered correctly by either A or B is 4.5.

Let's define the following variables:

X = Number of questions answered correctly by A

Y = Number of questions answered correctly by B

(a) Expected number of questions answered correctly by both A and B:

We can use the formula for the expected value of the product of two independent random variables:

E(X × Y) = E(X) × E(Y)

The probability of A answering a question correctly is 0.7, and the probability of B answering a question correctly is 0.4.

Since the questions are independent, we can calculate the expected values for X and Y:

E(X) = 10 (number of questions) × 0.7 (probability of A answering correctly) = 7

E(Y) = 10 (number of questions) × 0.4 (probability of B answering correctly) = 4

Now, the expected number of questions answered correctly by both A and B is:

E(X× Y) = E(X) × E(Y)

= 7×4

= 28

(b) Variance of the number of questions answered correctly by either A or B:

Variance is calculated differently for independent events. Since A and B's performances are independent, we can use the following formula:

Var(X + Y) = Var(X) + Var(Y)

The variance of a binomial distribution with n trials and probability p of success is given by np(1-p).

For A and B:

Var(X) = 10× 0.7 × (1 - 0.7)

= 2.1

Var(Y) = 10 × 0.4× (1 - 0.4)

= 2.4

Now, the variance of the number of questions answered correctly by either A or B is:

Var(X + Y) = Var(X) + Var(Y)

= 2.1 + 2.4

= 4.5

The mean distance of the earth from the sun (let's call it d) is 93 million miles. The distance varies as much as 1.6 million miles. Write the equation that describes the possible distances of the earth from the sun, using as distance unit millions of miles.

Answers

Answer:

Kindly check explanation

Step-by-step explanation:

Given that :

Mean distance of earth from the sun = 93 million miles

Let mean distance of earth from the sun = d

The variation on the distance is as much as 1. 6 million miles

Possible distances of the earth from the sun can be modeled using :

|d - 93| = ± 1.6

Where d = distance from earth to the sun

d = - 1.6 million + 93 million

d = 91.4 million

d = 1.6 million + 93 million

d = 94.6 million

Hence, possible distance from earth to the sun :

91.4 < d < 94.6

72=1/2h(4+5) solve for h

Answers

Answer:

h=16

Step-by-step explanation:

Simplify —

Equation at the end of step

72 - ((— • h) • 9) = 0

STEP

Rewriting the whole as an Equivalent Fraction

2.1 Subtracting a fraction from a whole

Rewrite the whole as a fraction using 2 as the denominator :

72 72 • 2

72 = —— = ——————

1 2

Equivalent fraction : The fraction thus generated looks different but has the same value as the whole

Common denominator : The equivalent fraction and the other fraction involved in the calculation share the same denominator

Adding fractions that have a common denominator :

2.2 Adding up the two equivalent fractions

Add the two equivalent fractions which now have a common denominator

Combine the numerators together, put the sum or difference over the common denominator then reduce to lowest terms if possible:

72 • 2 - (9h) 144 - 9h

————————————— = ————————

2 2

STEP

Pulling out like terms

3.1 Pull out like factors :

144 - 9h = -9 • (h - 16)

Equation at the end of step

-9 • (h - 16)

————————————— = 0

STEP

When a fraction equals zero

4.1 When a fraction equals zero ...

Where a fraction equals zero, its numerator, the part which is above the fraction line, must equal zero.

Now,to get rid of the denominator, Tiger multiplys both sides of the equation by the denominator.

Here's how:

-9•(h-16)

————————— • 2 = 0 • 2

Now, on the left hand side, the 2 cancels out the denominator, while, on the right hand side, zero times anything is still zero.

The equation now takes the shape :

-9 • (h-16) = 0

Equations which are never true:

4.2 Solve : -9 = 0

This equation has no solution.

A a non-zero constant never equals zero.

Solving a Single Variable Equation:

4.3 Solve : h-16 = 0

Add 16 to both sides of the equation :

h = 16

sorry I cannot give the answer through typing but you have to make h the subject, so divide by (4+5), divide by 1/2 and that should be h=31.5

Step-by-step explanation:

To factor 2x² + 10, we can first factor out the greatest common factor of the terms, which is 2:

2x² + 10 = 2(x² + 5)

We can't factor anymore, so the answer is:

2(x² + 5)

Answer:

2(x² + 5)

Step-by-step explanation:

To factorise this, do the distributive property backwards. In other words:

2x² + 10

2x² ÷ 2 + 10 ÷ 2

x² + 5

2(x² + 5)

If $11000 yields $1100 over 5 years, what is the interest rate?

Answers

Answer:

1.92449%

Step-by-step explanation:

Simple Interest Rate Formula: A = P(1 + r)ⁿ

Step 1: Define variables

Principle amount P = 11000

Total amount A = 11000 + 1100 = 12100

Years n = 5

Step 2: Substitute and Evaluate for r

12100 = 11000(1 + r)⁵

11/10 = (1 + r)⁵

1.01924 = 1 + r

r = 0.019245

Step 3: Convert to percentage

0.019245 × 100 = 1.92449%

prove that the sum of the squares of any two odd numbers is always even

Answers

Answer:

proof below

Step-by-step explanation:

Remember that a number is even if it is expressed so n = 2k. It is odd if it is in the form 2k + 1 (k is just an integer)

Let's say we have to odd numbers, 2a + 1, and 2b + 1. We are after the sum of their squares, so we have (2a + 1)^2 + (2b + 1)^2. Now let's expand this;

(2a + 1)^2 + (2b + 1)^2 = 4a^2 + 4a + 4b + 4b^2 + 4b + 2

= 2(2a^2 + 2a + 2b^2 + 2b + 1)

Now the sum in the parenthesis, 2a^2 + 2a + 2b^2 + 2b + 1, is just another integer, which we can pose as k. Remember that 2 times any random integer, either odd or even, is always even. Therefore the sum of the squares of any two odd numbers is always even.
