Step-by-step explanation:

The most restrictive level of significance that would suggest the company should raise rates is a p-value less than or equal to 0.01.

Hypothesis testing is a statistical method that is used to make decisions about a population based on a sample of data.

It involves testing a null hypothesis (H0) against an alternative hypothesis (Ha) using statistical techniques.

We have,

To determine if the increase in the average cost per claim is statistically significant, we can perform a hypothesis test.

Let's use a one-sample t-test, where:

Null hypothesis (H0): The average cost per claim is still $2,200.

Alternative hypothesis (Ha): The average cost per claim is greater than $2,200.

We can use a t-test because we have a sample mean, sample size, and population standard deviation.

The test statistic is calculated as:

t = (sample mean - hypothesized mean) / (standard deviation/√ (sample size))

Plugging in the values given, we get:

t = (2350 - 2200) / (500 / √(40))

t = 4.38

Using a t-table with degrees of freedom (df) = 39 (sample size - 1), we can find the p-value associated with this test statistic.

At the 0.01 level of significance (most restrictive level), the critical t-value is 2.704.

Since our calculated t-value is greater than the critical t-value, we reject the null hypothesis and conclude that there is evidence to suggest that the average cost per claim has increased.

Therefore,

The most restrictive level of significance that would suggest the company should raise rates is a p-value less than or equal to 0.01.

Answer:

I am not sure but I think the answer is 34.28

Step-by-step explanation:

Sorry if that is the wrong answer

Hope this helped

Answer:

34.28 ft^2

Step-by-step explanation:

Area of rectangular portion  7 x 4 = 28

 area of semicircle with radius 2

     1/2   *  pi (2)^2

Added together = 34.28 ft^2

Answer:

infinite solutions

Step-by-step explanation:

Hey there!

In order to solve this problem, we need to first distribute the [tex](x+4)(x-4)[/tex]

This is equal to [tex]x^2-16[/tex]

Now we can combine like terms

[tex]x^2[/tex] and [tex]-x^2[/tex] cancel out

also

[tex]16[/tex] and [tex]-16[/tex] cancel out

The equation ends up as 0 = 0

So the answer to this answer is infinite solutions

Perimeter is the combined ammount of all the sides added together.

For example, if a square has sides of 4, it would be 16 because 4+4+4+4 = 16 units.

Answer:

Perimeter is the total distance around the outside of a shape.

Step-by-step explanation:

A perimeter is a closed path that encompasses, surrounds, or outlines either a two dimensional shape or a one-dimensional length. The perimeter of a circle or an ellipse is called its circumference. Calculating the perimeter has several practical applications. A calculated perimeter is the length of fence required to surround a yard or garden. The perimeter of a wheel/circle (its circumference) describes how far it will roll in one revolution. Similarly, the amount of string wound around a spool is related to the spool's perimeter; if the length of the string was exact, it would equal the perimeter.

Answer:

64π or 200.96

Step-by-step explanation:

The area of a circle is [tex]\pi r^2[/tex]. The radius of the circle is half the diameter, which is 16/2 = 8. The area of the circle is 64π.

Answer:

64π = area
200.96 = area

Step-by-step explanation:

Diameter = radius * 2

16 = 2r

radius = 8

Radius^2 * π = area

8^2 * π = area

64π = area

64*3.14 = area

200.96 = area

Answer:

21.5 cm² (nearest tenth)

Step-by-step explanation:

To find the shaded region, subtract the area of the circle from the area of the square.

Square

Area of the square = 10² = 100 cm²

Circle

Given diameter of circle = 10 cm

⇒ radius = 10 ÷ 2 = 5 cm

⇒ Area of the circle = π · 5² = 25π cm²

Area of shaded region

= area of square - area of circle

= 100 - 25π

= 21.46018366...

= 21.5 cm² (nearest tenth)

The triangle is rotated about an axis then it creates a cone and the approximate circumference of the base is 63 mm. Then the correct option is C.

It deals with the size of geometry, region, and density of the different forms both 2D and 3D.

The equilateral triangle shown is rotated about line a.

Each side of the triangle measures 20 mm.

If the triangle is rotated about an axis then it creates a cone.

Then the radius of the cone will be

[tex]\rm r = \dfrac{20}{2} = 10 \ mm[/tex]

Then the height of the cone will be

[tex]\rm h = 20 \sin 60^o\\\\h = 17.32 \ mm[/tex]

Then the circumference of the base circle will be given as

[tex]\rm Circumference = 2 \pi r\\\\Circumference = 2 \pi \times 10\\\\Circumference = 62.8318 \approx 63 \ mm[/tex]

Step 1:  Determine what negative association is

Negative association basically means that the best-fit line for the scatter plot would be in a downwards slope which means that it has a negative association.  

In the given examples, Option A wouldn't work because we can see that the best-fit line would be going up which is a positive association.  Option B would work because we see the downward slope.  Option C wond't work for the same reason as Option A.  And finally Option D would work since we have a downward slope.

Step-by-step explanation:

Formulae

(where r is the radius of the circle)

The railing of the circular fountain is the circumference of a circle.

The area of the fountain is the area of a circle.

First, find the radius by using the circumference formula:

Given:

[tex]\implies 132=2 \pi r[/tex]

[tex]\implies r=\dfrac{132}{2 \pi}=\dfrac{66}{\pi}[/tex]

Now input the found value of r into the formula for the area of a circle:

[tex]\begin{aligned}\implies \textsf{Area} & =\pi \left(\dfrac{66}{\pi}\right)^2\\\\ & = \dfrac{4356}{\pi}\\\\ & = \dfrac{4356}{3.14}\\\\ & = 1387.261146...\\\\ & = 1387.3 \: \sf ft^2\:(nearest\:tenth)\end{aligned}[/tex]

To subtract mixed numbers with different denominators, follow these steps:

1. Rename the fractions using a common denominator.

2. Subtract whole numbers from whole numbers. You might need to regroup first.

3. Subtract fractions from fractions.

4. Simplify, if needed.

Let's try it with [tex]2\frac{3}{5}-1\frac{1}{4}[/tex]

First, rename the fractions using a common denominator. The least common denominator of these fractions is 20. Multiply to make equivalent fractions with 20 as the denominator.

[tex]\frac{3x4}{5x4}=\frac{12}{20}[/tex]        [tex]\frac{1x5}{4x5}=\frac{5}{20}[/tex]

Rewrite the problem and subtract the whole numbers.

[tex]2\frac{12}{20}-1\frac{5}{20}=1\frac{?}{?}[/tex]

Now, subtract the fractions. Subtract the numerators and keep the denominator the same.

[tex]2\frac{12}{20}-1\frac{5}{20}=1\frac{7}{20}[/tex]

This answer is already in its simplest form, so there is no need to simplify it.
