(x + 4) (x - 4) - x² + 16
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
A student said that the sum of the measures of a pair of adjacent angles must equal 180°. Is the student correct?
Choose the correct answer and explanation
OA) The student is correct; adjacent angles must share a common vertex and sum to 180°
OB) The student is not correct; two adjacent angles form a right angle, so the sum is always equal to 90°
OC) The student is correct; any pair of adjacent angles forms a straight line, and the angle measure of a straight line is 180°
D) The student is not correct; a pair of adjacent angles must share a common vertex, share a common side, and not overlap. They
may equal 180° but do not have to

The division is one of the four fundamental arithmetic operations. The filling that Camilo uses in each tray is 10.667 ounces.
What is Division?Division is one of the four fundamental arithmetic operations, which tells us how the numbers are combined to form a new one.
The total filling that was available with Camilo is 32 ounces, which he put in three different trays equally. Therefore, the filling available in each tray is equal to,
[tex]\rm \text{Filling in each tray} = \dfrac{\text{Total Filling}}{\text{Number of tray}}\\\\\text{Filling in each tray} = \dfrac{32\ ounces}{3} = 10.667 ounces[/tex]

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)

Answer:
2^11 * 3^3 * 5^6.
Step-by-step explanation:
c = 2^10 * 3 * 5^6
18c = 2^10 * 3 * 5^6 * 18
= 2^10 * 5*6 * 54
= 2^10 * 5^6 * 2 * 27
= 2^10 * 5^6 * 2* 3^3
= 2^10 * 2 * 3^3 * 5^6
= 2^11 * 3^3 * 5^6
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.

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.

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]
