The volume of the cylinder is 169.7. (Option C)

Based on the provided information, let the radius of the cylinder be r and diameter of the cylinder be 2r. The diameter and height of the circular cylinder is the same. When examining the cross section of the cone and cylinder, there are two similar triangles. Hence,

(15 – 2r)/15 = r/5

5(15 – 2r)= 15r

75 – 10r = 15r

r = 3

Volume of the cylinder = πr^2h where r is the radius of the cylinder and h is the height of cylinder. As h = 2r, Hence,

V = πr^2(2r) = (22/7)(3^2)(6) = 169.7

Note: The question is incomplete as the options are incorrect. The correct options are A) 127.5 B) 151.6 C) 169.7 D) 168.5

Answer:

​x + 49 + 28 = 180​

Step-by-step explanation:

​The angles on a straight line with x° are 28° and 49° respectively, side by side with x°. This is because, vertical angles are equal. Therefore, the angle vertically opposite 28° and 49° are equal to 28° and 49° respectively.

Therefore, since angles on a straight line is 180°, thus:

The trigonometric equation is 5sin²x + 3sinx - 1 = 0.

What is a trigonometric equation?

A trigonometric equation is one that incorporates a variable-based trigonometric function. One illustration of a trigonometric equation is sin x + 2 = 1. This equation or one that is more complicated, such as sin2 x - 2 cos x - 2 = 0, can be used in the equations.

Here, we have

Given: (5/2)cos2x - 1/2 = 3sinx

We know that

cos2x = 1 - 2sin²x

Then our equation become

(5/2) (1 - 2sin²x) - 1/2 = 3sinx

5/2 - 5sin²x - 1/2 = 3sinx

2 - 5sin²x = 3sinx

-5sin²x + 2 - 3sinx = 0

5sin²x + 3sinx - 1 = 0

Hence, the trigonometric equation is 5sin²x + 3sinx - 1 = 0.

Answer:

The statement that is a claim that cannot be supported is **D. Smith Delivery Service will improve a person's business**. This statement is a claim because it asserts that using Smith Delivery Service will have a positive impact on a person's business. However, there is no evidence provided in the advertisement to support this claim.

There are two types of errors that could be made:

a Type I error and a Type II error.

We have,

In step 5 of the hypothesis test, we make a decision to either reject or fail to reject the null hypothesis.

If we reject the null hypothesis, there are two types of errors that could be made:

a Type I error and a Type II error.

A Type I error occurs when we reject a true null hypothesis.

In this context, it means that we conclude that the percentage of packages delivered late is greater than 13% when in reality it is not.

This error is also known as a false positive.

A Type II error occurs when we fail to reject a false null hypothesis.

In this context, it means that we conclude that the percentage of packages delivered late is less than or equal to 13% when in reality it is greater than 13%. This error is also known as a false negative.

The probability of making a Type I error is denoted by α, which is given in the problem statement as α = 0.01.

Therefore, if we reject the null hypothesis, there is a 1% chance that we are making a Type I error.

Thus,

The probability of making a Type II error depends on the effect size, sample size, and significance level of the test.

Answer:

$432.9

Step-by-step explanation:

The z score is used to determine by how many standard deviations the raw score is above or below the mean. The z score is given as:

\(z=\frac{x-\mu}{\sigma}\\\\where\ x=raw\ score, \mu=mean,\sigma=standard\ deviation\)

Given that μ = $400, σ = $20

P(z > z*) = 0.05

P(z < z*) = 1 - 0.05 = 0.95

z* = 1.645

\(z=\frac{x-\mu}{\sigma} \\\\1.645=\frac{x-400}{20}\\\\x-400=32.9\\\\x=432.9\)

Therefore $432.9 should be budgeted for weekly repairs and maintenance so that the probability the budgeted amount will be exceeded in a given week is only 0.05.

The sentence translation of "2/3y - 9 < y + 1" is "Nine less than two-thirds of a number is less than the number."

To translate the inequality expression "2/3y - 9 < y + 1" into a sentence, we can break it down into smaller parts:

"2/3y" represents two-thirds of a number.

"9" represents the number nine.

"y + 1" represents the number increased by one.

Now let's construct the sentence:

"Nine less than two-thirds of a number" - This refers to the expression "2/3y - 9," indicating that we have subtracted nine from two-thirds of a number.

"is less than" - This is the comparison symbol in the inequality.

"the number" - This refers to the expression "y + 1," representing the number increased by one.

Combining these parts, we form the sentence: "Nine less than two-thirds of a number is less than the number."

Hence, the correct sentence translation of "2/3y - 9 < y + 1" is "Nine less than two-thirds of a number is less than the number."

No, the square roots of perfect squares always do not be irrational numbers.

We need to describe whether the square roots of perfect squares always be irrational numbers.

A perfect square is a positive integer that is obtained by multiplying an integer by itself. In simple words, we can say that perfect squares are numbers that are the products of integers by themselves. Generally, we can express a perfect square as x², where x is an integer and the value of x² is a perfect square.

Irrational numbers are the set of real numbers that cannot be expressed in the form of a fraction, p/q where p and q are integers. The denominator q is not equal to zero (q ≠ 0).

So, the square roots of perfect squares are rational numbers and can be placed on a number line. The square roots of non-perfect squares are irrational numbers.

Answer:

26 5/12

Step-by-step explanation:

n − 2/3 = 25 3/4                            Add 2/3 to both sides

n - 2/3 + 2/3 = 25 3/4 + 2/3         Combine

n = 25 3/4 + 2/3

Work with the fractions

3/4 + 2/3                                      The lowest common denominator is 12

(3*3)/(3*4) = 9 / 12

(2*4)/(3*4) = 8/ 12

9/12 + 8/12 = 17/12 = 1 5/12

Now you need to add 1 to 25

1 + 25 = 26

Slope  of a Line

Suppose we know a line passes through points A(x1,y1) and B(x2,y2). The slope can be calculated with the equation:

\(\displaystyle m=\frac{y_2-y_1}{x_2-x_1}\)

The points plotted by Carlos are (-4,-4) and (0,3), thus the slope is:

Answer and equation: If we choose two whole numbers; 8 and 10

We want to divide certain numbers by 8 and 10 to get 9 remainder 5.

In this case; 77 divided by 8 is equal to 9 rem 5

and 95 divided by 10 is equal to 9 rem 5

To justify which is greater, we use decimal division;

= 77 divided by 8 we get 9.625 ( 77 ÷ 8 = 9.625)

and

= 95 divided by 10 is equal to 9.5 (95 ÷10 = 9.5)

Therefore; the first case is greater since 9.625 is greater than 9.5

That is; 9 rem 5 got after dividing 77 by 8 is greater than 9 rem 5 got after dividing 95 by 10.
