Pablo makes a spinner to model the probability of simultaneously flipping a "heads" on a nickel, a "heads" on a dime, and a "heads" on a quarter. He divides his spinner wheel into sections for each possible combination of coin flips, and he colors green the section representing simultaneously flipping three "heads." If he decides to spin the arrow on the spinner 24 times, how many times can he predict the arrow will land on the green section?
times

Answers

Using proportions, it is found that he predicts that the arrow will land on the green section 24 times.

What is a proportion?

A proportion is a fraction of a total amount.

Considering that each trial has a 1/2 probability of resulting in heads, the fraction correponding to the probability of simultaneously flipping three "heads" is given by:

\(p = \left(\frac{1}{2}\right)^3 = \frac{1}{8}\)

Considering that he does this 24 times, we apply the proportion, hence:

\(\frac{1}{8} \times 24 = 3\).

He predicts that the arrow will land on the green section 24 times.

Answers

The answer is 1 and 1/15.

\([Hello,BrainlyUser]\)

Answer:

\(1\frac{1}{15}\)

Step-by-step explanation:

To Convert to a mixed number..

First, Let's add both fraction.

\(\frac{2}{15} + \frac{14}{15}\)

The two fractions have like denominators so you can add the numerators.

\(\frac{2+14}{15}=\frac{16}{15}\)

The fraction

\(\frac{16}{15}\)

is the same as

\(16\) ÷ \(15\)

Convert to a mixed number using

long division for 16 ÷ 15 = 1R1, so

\(\frac{16}{15}=1\frac{1}{15}\)

Therefore,

\(\frac{2}{15}+\frac{14}{15}=1\frac{1}{15}\)

Hence, your answer is 1 1/15

Suppose the mean height for adult males in the U.S. is about 70 inches and the standard deviation is about 3 inches. Assume men’s heights follow a normal curve. Using the Empirical Rule, 95% of adult males should fall into what height range?

Answers

Question options :

a. They should be between 64 and 76 inches tall.

b. They should be close to the height that is 95% of the mean. That is, 66.5 inches, plus or minus 2 standard deviations.

c. They should be at or below the 95th percentile, which is 74.92 inches.

d. None of the above.

Answer: a. They should be between 64 and 76 inches tall.

Step-by-step explanation:

Given the following :

Assume men's height follow a normal curve ; and :

Mean height = 70 inches

Standard deviation= 3 inches

According to the empirical rule ;

Assuming a normal distribution with x being random variables ;

About 68% of x-values lie between -1 to 1 standard deviation of the mean. With about 95% of the x values lying between - 2 and +2 standard deviation of mean. With 99.7% falling between - 3 to 3 standard deviations from the mean.

Using the empirical rule :

95% will fall between + or - 2 standard deviation of the mean.

Lower limit = - 2(3) = - 6

Upper limit = 2(3) = 6

(-6+mean) and (+6+ mean)

(-6 + 70) and (6+70)

64 and 76

The range of height of adult males in U.S. using the 95% empirical rule is 64 to 76 inches

According to the given data

The mean height for adult males in the U.S. is about 70 inches

The standard deviation of heights is about 3 inches.

Considering the data to be normally distributed

According  to the empirical rule for normal distribution we can write that

95.45% of the data lies with in the range of

\(\rm \mu - 2\sigma \; to \; \mu +2\sigma\\\\where \\\mu = Mean\\\sigma = Standard \; deviation\)

We have to to determine that  using the Empirical Rule 95% of adult males should fall into what height range

According to the given data

\(\rm \mu = 70\\\rm \sigma = 3 \\\)

\(\rm Lower \; limit \; of \; the\; range \; of\; variation\; of \; height\; range = 70 - 2(3) = 64\)

\(\rm Upper \; limit \; of \; the\; range \; of\; variation\; of \; height\; range = 70 +2(3) = 76\)

So we can conclude that the range of height of adult males in U.S. using the 95% empirical rule is 64 to 76 inches

Find a particular solution to
d2y/dt2 + y = 1/cos t y(0)=0 y'(0)=0
Denote the natural logarithm by log NOT by In
You should assume that cos(t)>0 -- DO NOT include the absolute value

Answers

the particular solution to the given differential equation is y(t) = 0.

The characteristic equation for the differential equation is r^2 + 1 = 0, which has roots r = ±i.

Since the roots are complex, the general solution takes the form y(t) = c1 cos(t) + c2 sin(t), where c1 and c2 are constants.

Using the initial conditions y(0) = 0 and y'(0) = 0, we can solve for the constants as follows:

y(0) = c1 cos(0) + c2 sin(0) = c1(1) + c2(0) = c1 = 0

y'(t) = -c1 sin(t) + c2 cos(t)

y'(0) = -c1 sin(0) + c2 cos(0) = c2 = 0

Therefore, the particular solution is y(t) = 0.

Substituting this solution into the differential equation, we see that it satisfies the equation:

d^2y/dt^2 + y = 0 + 0 = 1/cos(t) * 0

The value of RE for the given triangle is 3 units.

What is Pythagoras Theorem?

A key idea in geometry known as the Pythagorean theorem outlines the relationship between the sides of a right triangle. It asserts that the square of the length of the longest side, known as the hypotenuse, is equal to the sum of the squares of the two shorter sides of a right triangle. In other words, if a and b are the measurements of a right triangle's two shorter sides and c is the measurement of the hypotenuse,

Triangle DRF is an right angle triangle.

Using Pythagoras Theorem we have:

c² = a² + b²

DF² = 27² + 9²

DF² = 729 + 81

DF² = 810

DF = √(810)

DF = 9 √(10)

Now, the value of DF = 9 sqrt(10).

In triangle DEF we have:

DE² = (9 √(10))² + (3 √(10))

DE² = 81 * 10 + 9 * 10

DE² = 900

DE = 30

A quilt square sewing project requires at least3 pieces of cloth for each square. Ashley wantsto complete

Answers

The number of pieces of cloth, x, she can use for her project 3 x 28 = 84 pieces of cloth.

Inequality calculation explained

As Ashley needs at least 3 pieces of cloth for each square, the total number of pieces of cloth she needs for 28 squares is 3 times the number of squares, which is 3 x 28 = 84 pieces of cloth.

To write an inequality to find the number of pieces of cloth, x, she can use for her project, we can set up the following inequality:

x ≥ 84

This inequality means that the number of pieces of cloth, x, must be greater than or equal to 84 in order for Ashley to be able to complete 28 squares with at least 3 pieces of cloth for each square.

The graph of this inequality is a vertical line passing through the point (84,0) on the x-axis and extending infinitely upwards. Any point on or to the right of this line represents a valid solution to the inequality, since it corresponds to a number of pieces of cloth that is greater than or equal to 84.

Therefore,  The graph does not show any points to the left of the line, since any such point would represent a number of pieces of cloth that is less than 84, which is not a valid solution to the inequality.
