A square is circumscribed about a circle with a diameter of 10 cm. What is the correct set up to find the area of the shaded region?
Answer:
21.5 cm² (nearest tenth)
Step-by-step explanation:
FormulaeArea of a square = x² (where x is the side length)Area of a circle = πr² (where r is the radius)Radius = 1/2 diameterSolutionTo 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)

What is the slope of the line that passes through the points (7, -6) and (6, -6)? Write your answer in simplest form.
Undefined
Solution:Notice that the x-coordinates of the points that the line intersects are the same.If the x-coordinates are the same, then the slope is undefined.If the slope is undefined, then the line's run is equal to 0 units.Remember the slope formula: Rise/RunRise - how many units we move up or downRun - how many units we move left or rightIf the run is zero, then we basically divide by zero, which we can't do.Hope it helps.

A circular fountain has 132 feet of railing around it. What is the area of the fountain, Use 3.14 for π.
Answer:
1387.2 ft² (nearest tenth)
Step-by-step explanation:
Formulae
Circumference of a circle = [tex]2 \pi r[/tex]Area of a circle = [tex]\pi r^2[/tex](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:
circumference = 132 ft[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]

Car insurance companies want to keep track of the average cost per claim. The current data in use for Auto Insurance R Us is an average of $2,200 for each claim with a standard deviation of $500. With this average, the company can stay competitive with rates but not lose money. However, the statistician for the company believes that the cost of the average claim has increased. He pulled 40 recent claims and found the average to be $2,350. Which most restrictive level of significance would suggest that the company should raise rates
Answer:
The answer is 5% because its correct lol
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.
What is hypothesis testing?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.

Find the area of a circle with a diameter of 16.
Either enter an exact answer in terms of piπpi or use 3.14 for piπpi and enter your answer as a decimal.
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

What shape is created by the rotation and what is the approximate circumference of the base? circumference of a circle: c = 2πr a cylinder with a circumference of about 63 mm a cylinder with a circumference of about 126 mm a cone with a base circumference of about 63 mm a cone with a base circumference of about 126 mm
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.
What is Geometry?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

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.

What is the perimeter of a shape?
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.
