The probability of getting exactly 1 red is 60/121

Probability theory, a branch of mathematics concerned with the analysis of random phenomena.

There is a bag filled with 5 blue and 6 red marbles.

A marble is taken at random from the bag, the color is noted and then it is replaced. Another marble is taken at random.

It is required to find the probability of getting exactly one red marble.

Now, the red marble can occur on the first draw or the second draw.

The probability of getting exactly 1 red marble from the first draw will be,

P(1) = 6/11 x 5/11

p(1) = 30/121

The probability of getting exactly 1 red marble from the second draw will be,

P(2) = 6/11 x 5/11

p(2) = 30/121

So, the total probability of the event will be,

P = P(1) + P(2)

P =  30/121 +  30/121

P = 60/121

hence, the probability of getting exactly 1 red is 60/121

In order for Lashonda to achieve a final average of 80, she must receive a score of 86 on her last exam.

Score is a numerical value or result that is used to indicate the performance or achievement of an individual or team in a particular activity or game. A high score indicates excellence or success while a low score indicates the opposite. Score is often used to track progress and can be used to compare individuals or teams against each other. Score can also be used as a measure of progress or improvement.

To calculate her score, we add up all of her previous exam scores (95 + 82 + 89 + 70 + 76) and divide them by 6 (the number of exams taken). This gives an average of 81. We then subtract the current average (81) from her desired average (80) to arrive at the score she must receive on her last exam (86).

Answer: f(x) = (x+8)^(1/2) - 9 / 12

Step-by-step explanation:

To find f(x), we need to apply the steps given in the problem in the order they are presented.

First, we add 8 to the input value x. This step is represented by the term x+8.

Next, we take the square root of the result from step 2. This step is represented by the exponent (1/2) on the term x+8.

Next, we subtract 9 from the result of step 3. This step is represented by the term -9.

Finally, we divide the result of step 4 by 12. This step is represented by the division operator '/' and the denominator 12.

So f(x) is a function that takes the input x, adds 8, takes the square root, subtracts 9, and divides by 12.

Answer:

f(x) = [√(x + 8) - 9]/12

Step-by-step explanation:
The expression f(x) begins with ->

Step 1: x + 8
Step 2: √(x + 8)
Step 3: √(x + 8) - 9
Step 4: [√(x + 8) - 9]/12

The equation is now:
f(x) = [√(x + 8) - 9]/12

i believe the answer is 18 3/10

Step-by-step explanation:

(a) The sum a + (a + 1) + (a + 2) + ... + (a + n - 1) is Sn = n/2 * (a + n)

It can be represented as the sum of an arithmetic series. The nth term of the series is (a + n - 1) and the first term is a.

The common difference between consecutive terms is 1. The formula to calculate the sum of an arithmetic series is:

[tex]Sn = n/2 * (2a + (n - 1)d)[/tex]

Where n stands for the number of terms, a will be the first term, and d is a common difference. By substituting the values for n, a, and d, we'll get:

Sn = n/2 * (2a + (n - 1) * 1)

Sn = n/2 * (2a + n - 1)

Sn = n/2 * (a + n)

(b) The pairs of positive integers (a,n) that will fulfill the conditions are (10,10), (15,8), and (20,6).

To find all pairs of positive integers (a,n) such that n is greater than 2 and a + (a + 1) + (a + 2) + ... + (a + n - 1) = 100, we can rearrange the formula from the above problem part (a) to solve for a:

Sn = n/2 * (a + n) = 100

a = 2 * (100/n) - n

Since a must be a positive integer, we can use trial & error to find all possible values of n that make a positive integer. Here are some of the solutions:

For n = 10, a = 10.

For n = 8, a = 15.

For n = 6, a = 20.

So the pairs of positive integers (a,n) that satisfy the conditions are (10,10), (15,8), and (20,6).

Nathan can cut 3 one-acre lawns with a full tank of gas

What is Cross multiplying fractions?

Cross multiply fractions by multiplying one fraction's denominator by the second fraction's numerator and then comparing the two values. The larger fraction is the one with the higher value.

Since Nathan's lawnmower uses one tank of gas to cut three one-acre lawns, it means that he can cut one one-acre lawn with 1/3 of a tank of gas. So, if he has a full tank of gas, he can cut one-acre lawns equal to the number of times 1/3 fits into a full tank. In other words, he can cut a full tank of gas divided by 1/3 of a tank of gas.

The number of one-acre lawns Nathan can cut with a full tank of gas is:

1 tank / (1/3 tank) = 3 one-acre lawns.

So, Nathan can cut three one-acre lawns with a full tank of gas.

Given that, a 12-ounce soda can has a height of 4.875 inches.

We know that, 1 ounce = 1.805 cubic inches

Here, 12 ounce = 21.6563 cubic inches

As we know, volume of cylinder is πr²h.

Now, 21.6563 = 3.14×r²×4.875

21.6563 =r²×15.3075

r²=21.6563/15.3075

In mathematical terms, the equation e^-2.5 = h states that the exponential value of -2.5 (e^-2.5) is equal to the variable h. To convert this equation into its logarithmic form, we can take the natural logarithm of both sides of the equation. The natural logarithm, represented by the function ln, returns the power to which e must be raised to obtain a given number.

So, taking the natural logarithm of both sides of the equation, we have:

ln(e^-2.5) = ln(h)

Since ln(e^x) = x, we can simplify the left side of the equation:

ln(h) = -2.5

Thus, the logarithmic equivalent of the equation e^-2.5 = h is ln(h) = -2.5.

The logarithmic equation ln(h) = -2.5 can be interpreted as follows: the natural logarithm of h is equal to -2.5. In other words, h is the result of raising e to the power of -2.5. To find the value of h, we can use the exponential function:

h = e^-2.5

Therefore, the original equation e^-2.5 = h and the logarithmic equation ln(h) = -2.5 are mathematically equivalent and can be used interchangeably.

It is worth mentioning that logarithms are used in many areas of mathematics and science, including engineering, finance, and physics. They allow us to simplify complex calculations and to solve problems that are otherwise difficult or impossible to solve.

Answer:

To find the time it takes for a car to stop from a velocity of 35 m/s using a braking force of 4000 N, we can use the following formula:

vf = vi + at

where

vf = final velocity (0 m/s in this case, since the car is stopping)

vi = initial velocity (35 m/s)

a = acceleration, which can be calculated as a = F/m, where F is the braking force (4000 N) and m is the mass of the car (2000 kg)

t = time

Rearranging the formula:

t = (vf - vi)/a = (0 - 35) / (4000 / 2000) = (35) / (2) = 17.5 s

Answer:

It takes the car 17.5 seconds to stop from a velocity of 35 m/s with a braking force of 4000 N.

Let's call the number of strawberry cupcakes "s".

So the number of chocolate cupcakes is 4s and the number of vanilla cupcakes is 3s.

When there is an irrational relationship between the lengths of two line segments, the line segments are also said to be incommensurable.

Answer:

Step-by-step explanation:

The total length of the road is 27 miles, and since each cottage is separated from its neighbor by a distance of 1, 2, 3, 4, ..., 25, or 26 miles, the total length of the road occupied by these distances must sum to 27 miles. This is because the road connects the six cottages.

One possible distribution is:

Cottage 1 and 2 are 1 mile apart.

Cottage 3 and 4 are 2 miles apart.

Cottage 5 and 6 are 3 miles apart.

Cottages 1 and 3 are 4 miles apart.

Cottages 2 and 4 are 5 miles apart.

Cottages 3 and 5 are 6 miles apart.

Cottages 4 and 6 are 7 miles apart.

...

Cottages 1 and 6 are 25 miles apart.

Cottages 2 and 5 are 26 miles apart.

A second possible distribution can be obtained by reversing the order of the distances between the cottages. That is:

Cottages 2 and 5 are 26 miles apart.

Cottages 1 and 6 are 25 miles apart.

Cottages 4 and 6 are 7 miles apart.

Cottages 3 and 5 are 6 miles apart.

Cottages 2 and 4 are 5 miles apart.

Cottages 1 and 3 are 4 miles apart.

Cottage 5 and 6 are 3 miles apart.

Cottage 3 and 4 are 2 miles apart.

Cottage 1 and 2 are 1 mile apart.

There may be other possible distributions, but these two demonstrate that there are multiple ways to arrange the distances between the cottages while still satisfying the constraint that the distances must sum to 27 miles.
