Question is down below, match the answer choices with the units.

The null hypothesis should not be rejected. There is insufficient evidence that the true diameter differs from 0.5 inches.

We are given that,

n = 15

t-value = 1.66

Significance level;α = 0.05

So, DF = n - 1 = 15 - 1 = 14

In the attached one-sample t-table, we can see that the p-value of 0.06

corresponds to a t-value of 1.66 and a DF of 14

Due to the P-value of 0.06, it is greater than the significance level of 0.05. Based on the results, we are not rejecting the null hypothesis. There is insufficient evidence to conclude that the true diameter in active attachment is different from 0.5

Based on the gross pay for Melika Yasin, and the fact she claims no allowances and is married, the amount withheld from her pay for Federal Income Tax is $43.

Melika Yasin had a gross pay of $355.00 for the week. This amount is more than $350 but less than $360.

Melika Yasin therefore falls into the bracket of "At least $350 but less than $360."

She also claims no allowances in this bracket. This means that the amount that would be withheld for Federal Income Tax according to the table would be $43.

Answer: No, at least one segment length is not preserved, making this a nonrigid transformation.

Step-by-step explanation: A rigid transformation implies that both the shape and size are not changed. The second answer is right because the length of segment JK (2 units) is not preserved when mapped onto J'K' (5 units).

Considering Justin's serve, it is found that:

a) The ball traveled 21.4 feet, which means that Justin's estimate is correct.

b) An assumption regarding the angle of Justin's serve was made.

c) The Pythagorean Theorem was used to solve this mathematical problem.

The Pythagorean Theorem relates the length of the legs [tex]l_1[/tex] and [tex]l_2[/tex] of a right triangle(triangle which has an angle of 90º between the two legs) with the length of the hypotenuse h, stating that the hypotenuse squared is the sum of the legs squared, according to the following rule:

[tex]h^2 = l_1^2 + l_2^2[/tex]

Assuming that the ball was served at an angle of 90º, the situation can be summarized as follows:

Hence the Pythagorean Theorem is applied and the distance is calculated as follows:

d² = 7.5² + 20²

d = sqrt(7.5² + 20²)

d = 21.4 feet.

The absolute value of (-8) would be 8 on number line.

The absolute value of any number represented on number line is given as the distance of the number from zero on a number line, when counted on whichever side it is present that is either negative or positive. In mathematical notation, absolute value is defined as the modulus of the number, enclosed in two straight lines. For example: |-8| or |8| would have absolute value 8 even though both the numbers are represented on negative and positive side of zero respectively on the number line. The absolute value of any number which is also a real number is the non-negative value of that number irrespective of its sign. Number line figure is attached below.

The amount of cash that as kept in the bank is $937500.

Let's have x represent the amount of cash.

One portion of it pays 0.5%, so 0.005x; the other portion pays 3.5%, so 0.035x. This gives us:

0.005x + 0.035x = 37500

Combining like terms:

0.040x = 37500

Step-by-step explanation:

7.99 is the basic fixed cost per month. this is charged, even if there are no songs (x = 0) downloaded.

and so, 1.75 is the cost per downloaded song in addition to the basic fixed cost. so, yes, the number of downloaded songs has to be multiplied by the cost for a single song to get the total.

and so, 1.75 is the change in the total cost for every automakers download (every time x is increased by 1).

The perimeter can be found by adding all of the side lengths. A square has 4 sides.

a + a + a + a = P

However, we know that a square has congruent sides so we can manipulate this formula:

4a = P - where a is equal to the side length

Using a previous equation we know that a side length is equal to 2x and we know the value of x, to be 3. Therefore, a side length must be 6.

we can now input the value of the side length into the formula.

The approximate total of weight of the litter of  6 kittens 0.675kg

What is Weight ?

The force exerted on an object by gravity is known as its weight. The gravitational force acting on the item is referred to as weight in several common textbooks. Some people refer to weight as a scalar quantity that measures the gravitational force's strength.

Given,

The weight of one newborn kitten = 1/4 pounds
The value of pound in kilograms = 1pound = 0.45kg
convert the weight from  pound to kilograms = 1/4 x 0.45

                                                                              = 0.1125kg

Now, to find out total weight of litter of 6 kitten in kilograms

= 0.1125 x 6

= 0.675kg

The transformation has a horizontal shift right by 4 units and vertical shift upwards by 3 units.

What do you mean by transformation of a function ?

The modification of a graphed function to create a different version of the parent function is known as transformation.

For the given condition :

The function is y = (x - 4)² + 3.

The above function is transformed from the parent function which is y = x².

We know that , the horizontal shift depends on the value of h. The horizontal shift and it is described as:

y = f (x + h)

Then , the graph of function will be shifted to left by h units.

and

y = f (x - h)

Then , the graph of function will be shifted to right by h units.

If we compare both functions i.e., y = (x - 4)² and y = f (x - h), their is a difference of -1 , it meant shift is right by 4 units.

Now , we know that , the vertical shift depends on the value of k. The vertical shift is described as:

y = f(x) + k

Then , the graph of function will be shifted up by k units.

and

y = f(x) - k

Then , the graph of function will be shifted down by k units.

Here , if we compare functions i.e., y = (x - 4)² + 3 and y = y = f(x) - k ,  we find out that the graph of function will be shifted upwards by 3 units.

Therefore , the transformation has a horizontal shift right by 4 units and vertical shift upwards by 3 units.

Answer:

x = - 1 / 24

Step-by-step explanation:

-6 ( 6x - 1 ) + 9 = 36x + 18

First, solve the brackets.

-36x + 6 + 9 = 36x + 18

Then, subtract 36x by both sides.

-36x - 36x + 6 + 9 = 18

-72x + 15 = 18

Now, Subtract 15 by both sides.

-72x = 18 - 15

-72x = 3

Now divide both sides -72 by both sides.

x = - 3 / 72

x = - 1 / 24
