Answer:

Evan can go on 30 rides   (based on the assumption that Evan's parent gave him $20)

Step-by-step explanation:

Given that:

The admission to the fair  = $5

The cost per ride = $0.50

Let assume that the number of ride Evan can go = x

So if The cost per ride = $0.50

x ride = $0.50x

We are not told that he is given money by anybody, but let assume his parent gave him $20,

Then, if Evan pays $5 for admission into the fair. Then he will have $(20-5) = $15 left

The relation expressing how many rides Evan can go is:

0.5x = 15

Since the cost per ride = $0.5

x rides cost $15/0.5

x = 15/0.5

x = 30

Hence, Evan can go on 30 rides

What is an Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the cost of one sanitizing wipe be = A

Now , the equation will be

The cost of 100 sanitizing wipes = $ 12

So ,

The cost of 1 sanitizing wipe = cost of 100 sanitizing wipes  / 12

The cost of 1 sanitizing wipe = 12 / 100

The cost of 1 sanitizing wipe = $ 0.12

Therefore , the value of A is $ 0.12

Hence , The cost of one sanitizing wipe is $ 0.12

Using the given conditions that sin(20) = cos(2u) = tan(24) = 3, we can find the exact values of sin(2u), cos(2u), and tan(2u) using the double-angle formulas. By substituting the known values into the formulas, we can determine the exact values of these trigonometric functions.

Given sin(20) = 3, we can use the double-angle formula for sine to find sin(2u).

The double-angle formula for sine is sin(2u) = 2sin(u)cos(u). We know that sin(u) = -3/5, so we can substitute this value into the formula to calculate sin(2u).

Therefore, sin(2u) = 2(-3/5)(cos(u)).

Given cos(2u) = 3, we can use the double-angle formula for cosine to find cos(2u).

The double-angle formula for cosine is cos(2u) = cos^2(u) - sin^2(u). Since we already know sin(u) = -3/5 and cos(u) can be calculated using the Pythagorean identity (cos^2(u) = 1 - sin^2(u)), we can substitute these values into the formula to determine cos(2u).

Finally, given tan(24) = 3, we can use the double-angle formula for tangent to find tan(2u).

The double-angle formula for tangent is tan(2u) = (2tan(u))/(1 - tan^2(u)). By substituting the known value of tan(24) = 3 into the formula, we can calculate the exact value of tan(2u).

Answer:

false

Step-by-step explanation:

Answer:

False

Step-by-step explanation:

Quadratic equations have the highest degree on x as 2 (a squared value). The given equation has x^3 (assuming x3 is x^3 and not 3x), meaning that the equation is a cubic equation.

A 90% confidence interval for the difference in means of two populations with sample sizes of 32 and 43, respectively, can be constructed using the formula \($CI = (\bar{x}_1 - \bar{x}2) \pm t{\alpha/2} * SE$\), where \($SE = \sqrt{\frac{s_1^2}{n_1} + \frac{s_2^2}{n_2}}$\) and \($t_{\alpha/2} = \pm 1.695$\).

To construct a confidence interval for the difference in means of two populations, we can use the formula:

\($CI = (\bar{x}_1 - \bar{x}2) \pm t{\alpha/2} * SE$\)

where:

\($\bar{x}_1$\) and \($\bar{x}_2$\) are the sample means for populations X and Y, respectively

tα/2 is the critical value of the t-distribution with degrees of freedom (df) equal to the smaller of \((n_1 - 1)\) and \((n_2 - 1)\) and α/2 as the level of significance

SE is the standard error of the difference in means, which is calculated as follows:

\($SE = \sqrt{\frac{s_1^2}{n_1} + \frac{s_2^2}{n_2}}$\)

Given that a random sample of size 32 is selected from population X, and a random sample of size 43 is selected from population Y, we can compute the sample means and standard deviations:

Sample mean for population X: \($\bar{x}_1$\)

Sample mean for population Y: \($\bar{x}_2$\)

Sample standard deviation for population X: \(s_1\)

Sample standard deviation for population Y: \(s_2\)

Sample size for population X: \(n_1\) = 32

Sample size for population Y: \(n_2\) = 43

Assuming a 90% level of confidence, we can find the critical value of the t-distribution with \($df = \min(n_1-1, n_2-1) = \min(31, 42) = 31$\). We can use a t-distribution table or software to find the value of tα/2 = t0.05/2 = ±1.695.

Next, we can compute the standard error of the difference in means using the formula \($SE = \sqrt{\frac{s_1^2}{n_1} + \frac{s_2^2}{n_2}}$\)

Once we have computed the standard error and the critical value, we can construct the confidence interval:

\($CI = (\bar{x}_1 - \bar{x}2) \pm t{\alpha/2} * SE$\)

This confidence interval will give us an estimate of the true difference in means of the two populations, with 90% confidence that the true difference falls within the interval.

2^8 / 5 remainder = 1

2^9 / 5 remainder = 2

2^10 / 5 remainder = 4

2^11 / 5 remainder = 3

It can be seen that it generates a pattern which is

The pattern counts in 4's. If we follow the pattern and count to 2^30

= 100 / 4

= 25 ⇒ this is a multiple of 4 and multiples of 4 goes with remainder 1

This is to say

2^97 / 5 remainder = 2

2^98 / 5 remainder = 4

2^99 / 5 remainder = 3

2^100 / 5 remainder = 1

Hence 2^100 divided by 5 will give a remainder of 1

Answer:

x = 20 units

Step-by-step explanation:

Using the Altitude- on- Hypotenuse theorem

( leg of Δ SRQ )² = (part of hypotenuse below it ) × ( whole hypotenuse ), so

x² = 16 × (16 + 9) = 16 × 25 = 400 (take the square root of both sides )

x = \(\sqrt{400}\) = 20

The values of x, y and z for the right triangle are: x = √6, y = 3, and z = √10 respectively.

The perpendicular height of the right triangle divides the triangle in two triangles with the same proportions as the original triangle.

√15/(y + 2) = y/√15 {opposite/adjacent}

y(y + 2) = (√15)² {cross multiplication}

y² + 2y = 15

y² + 2y - 15 = 0

by factorization;

(y - 3)(y + 5) = 0

y = 3 or y = -5

by Pythagoras rule:

(√15)² = x² + y²

15 = x² + 3²

x = √(15 - 9)

x = √6

z² = (√6)² + 2²

z = √(6 + 4)

z = √10

The number of cards were sold for mother's day is 900 cards.

To calculate a total number using a percentage, first identify the percentage and the total number. Then divide the percentage by 100 to convert it to a decimal fraction. Finally, multiply the total number by the decimal fraction to calculate the total number.

For example, if the percentage is 10% and the total number is 200, first divide 10% by 100 to get 0.1. Then multiply 0.1 by 200 to get 20. The total number is 20.

In another example, if the percentage is 25% and the total number is 500, divide 25% by 100 to get 0.25. Then multiply 0.25 by 500 to get 125. The total number is 125.

It is important to remember that percentages are based on a whole, which is usually 100. Therefore, to use percentages to calculate a total number, it is necessary to first convert the percentage to a decimal fraction by dividing it by 100. Then, multiply the total number by the decimal fraction to calculate the total number.

36 cards is 4% of the total cards sold for Mother's Day.

Total number of cards = 36 / 4%

Total number of cards = 36 x 100/4

Total number of cards = 900 cards.
