Answer:
17.3 ft
Step-by-step explanation:
To find the second leg, use the following: √c² - a². Substitute c for 28, and a for 22.
b = √28² - 22² {Square 28 to get 784, and square 22 to get 484.}
b = √784 - 484 {Subtract 484 from 784 to get 300.}
b = √300 {Find the square root of 300.}
b = 17.32051 {Round to the nearest tenth.}
b = 17.3 ft.
The bottom of the ladder will be 17.3 ft from the bottom of the building.

A streaming music site changed its format to focus on previously unreleased music from rising artists. The site manager now wants to determine whether the number of unique listeners per day has changed. Before the change in format, the site averaged 131,520 unique listeners per day. Now, beginning three months after the format change, the site manager takes a random sample of 30 days and finds that the site now has an average of 124,247 unique listeners per day. Using the data provided below, calculate the p-value for the following hypothesis test:

Answer:
The p value is: 0.0301
Step-by-step explanation:
Given
[tex]\mu = 131520[/tex]
[tex]\bar x = 124247[/tex]
[tex]n = 30[/tex]
Required
Determine the p value
First, calculate the standard deviation of the given data.
This is calculated as:
[tex]\sigma = \sqrt{\frac{\sum(x - \bar x)^2}{n}}[/tex]
So, we have:
[tex]\sigma = \sqrt{\frac{(83700 - 124247)^2 + (84380- 124247)^2 + (89380- 124247)^2 + ..... + (156920- 124247)^2 + (168370- 124247)^2}{30}}[/tex]
[tex]\sigma = \sqrt{\frac{13427820070}{30}}[/tex]
[tex]\sigma = \sqrt{447594002.333}[/tex]
[tex]\sigma = 21156[/tex]
The test statistic is then calculated as:
[tex]t = \frac{\bar x - \mu}{\sigma/\sqrt n}[/tex]
[tex]t = \frac{124247 - 131520}{21156/\sqrt{30}}[/tex]
[tex]t = \frac{-7273}{21156/5.48}[/tex]
[tex]t = \frac{-7273}{3860.58}[/tex]
[tex]t = -1.88[/tex]
The p value is calculated as:
[tex]P(Z > -1.88)[/tex]
[tex]P(Z>-1.88) = 0.030054[/tex]
[tex]P(Z>-1.88) = 0.0301[/tex] --- approximated.
Hence, the p value is: 0.0301

The distance between two coordinate points is 11.66 units.
What is distance formula?The distance formula which is used to find the distance between two points in a two-dimensional plane is also known as the Euclidean distance formula. On 2D plane the distance between two points (x₁, y₁) and (x₂, y₂) is Distance = √[(x₂-x₁)²+(y₂-y₁)²].
The given coordinate points are (-3, -2) and (7, 4)
Substitute (x₁, y₁) =(-3, -2) and (x₂, y₂)=(7, 4) in distance formula, we get
Distance = √[(7+3)²+(4+2)²]
= √(100+36)
= √136
= 11.66 units
Therefore, the distance between two coordinate points is 11.66 units.

Write integer to describe each situation. A. Charge of 24$ is debited from a bank account
Answers
Answer:
-24
Step-by-step explanation:
To represent a charge of $24 debited from a bank account, this type of transaction being described as a debit means that a sum of $24 was deducted from the account, meaning the total amount in the account will reduce after this transaction takes place. Hence a charge of $24 being debited will take a negative sign as could be represented by the integer - 24

fish each. The other 10 aquariums have salt water with 6 fish each. Write an
equation that could be used to find f, the total number of fish at the pet store?
(Equations Review)
Your answer
Answers
Answer:
f = (20 × 15) + (10 × 6)
Step-by-step explanation:
You are just find how many fish are salt water and how many freshwater and adding them together. The total number of aquariums is irrelevant in this case.
Answer:
20 x 15 = A A= 300
10 x 6 = B B=60
A + B = F F= 360
300 + 60 = F
300 + 60 =360

Six scatterplots are shown. Suppose regression lines were generated for them, then order their correlation coefficients from least to greatest.
A) C, D, B, A, E, F
B) F, E, D, C, B, A
C) C, B, D, E, A, F
D) A, B, C, D, E, F
Answers
Answer:
C) C, B, D, E, A, F
Step-by-step explanation:
The closer the data points are to each other along the line of best fit on a scatter plot, the greater the correlation coefficient and vice versa.
Therefore, the scatter plot that has the least correlation coefficient would be the scatter plot with the data points that are farther apart from each other along the line of best fit which is C, followed by B, D, E, A, and F.
Ann's rent increased from $1,200 to $1,350.
By what percent did her rent increase?
Answers
Answer: Percentage increase: 12.5%
Step-by-step explanation: (EXAMPLE) percentage increase/decrease = (Vnew - Vold) / Vold × 100%
Example #1
Price percentage increase from old value of $1000 to new value of $1200 is caluclated by:
percentage increase = ($1200 - $1000) / $1000 × 100%
= 0.2 × 100% = 20%
Answer:
12.5%
Step-by-step explanation:
1350 - 1200 / |1200| × 100% =
150 / 1200 × 100 = 12.5%
A writer buys a new laptop for $1866. Every year the laptop decreases in value by 20%.
Answers
Answer:
the answer is A
A function that represents a $1866 laptop that decreases in value by 20% each year is f(n)=1866(1.2)ⁿ.
What is the function?Functions are the fundamental part of the calculus in mathematics. The functions are the special types of relations. A function in math is visualized as a rule, which gives a unique output for every input x.
Given that,
$1866 laptop that decreases in value by 20% each year.
Here, f(n)=1866(1+20%)ⁿ, where n is the number of years
f(n)=1866(1+20/100)ⁿ
f(n)=1866(1.2)ⁿ
Therefore, a function that represents a $1866 laptop that decreases in value by 20% each year is f(n)=1866(1.2)ⁿ.
