Find the shaded area of each figure, round your answer to one decimal place if necessary
Answers
Step-by-step explanation:
radius of circle = 5 yd ------ ( given )
height of triangle = 16 yd --- ( given )
base of triangle = 16 yd ----- ( given )
area of triangle = 1/2 × base × height
= 1/2 × 16 × 16
= 128 yd²
area of circle = π × radius²
= 3.14 × 5 × 5 --- ( π = 3.14 )
= 78.5 yd²
---------------------------------------area of shaded portion = area of triangle - area of circle
area of shaded portion= 128 yd²-78.5 yd²
area of shaded portion = 49.5 yd²

Part B Isabella's mother sells the peas and gets $3 for each square foot. So, multiply your answer from Part A by 3 to calculate how much money Isabella's mother made.
Answers
Answer:
See Explanation
Step-by-step explanation:
The question is incomplete as the solution to part A (or part A itself) is not given. To solve this, I will assume a value to the supposes solution to part A.
From the question:
1 square foot is sold at $3.
This implies that:
p square foot will be sold at $3p.
So, total sales can be calculated using:
[tex]Total = 3p[/tex]
Now assume that p is 10 square feet (from part A).
The total will be:
[tex]Total = 3*10[/tex]
[tex]Total = \$30[/tex]

Using the equation y = kx, we need to find k for that data
150 = k(1250)
150/1250 = k
0.12 = k
You can confirm that by doing the same with the second row, but I won’t put that here. It’s the same.
Dollars/kilowatt-hour is the label for the k of each equation (0.12, 0.15). We calculated dollars divided by (per) kWh.
Company P is less expensive than company M, because 0.12 < 0.15.
We need to buy 2,375 kWh of electricity from company P. The equation y = kx applies, where y is unknown, k = 0.12, and x = 2,375
y = (0.12)(2375)
y = $285

Find the discriminant and determine the number of real roots for each equation. Show steps.
-3p^2 - 2p = 0
Answers
Answer:
discriminant: 4; number of real roots: 2
Step-by-step explanation:
The coefficients a, b and c of this quadratic are {-3, -2, 0}.
Thus, the discriminant b^2 - 4ac is (-2)^2 - 4(-3)(0), or 4.
Because the discriminant is positive, this quadratic has two real, unequal roots.
-3p^2 - 2p can be factored as follows: -p(3p + 2). If we set this expression equal to zero, we can find the roots: {-2/3, 0}

A business analyst is investigating whether the mean amount of purchases made by customers at an online department store is greater than $100. The analyst obtained a random sample of 56 orders and calculated a sample mean of $102.30 and a sample standard deviation of $5.30.
Which of the following is an appropriate test for the investigation?
Answers
Answer:
B
Step-by-step explanation:
I don't know
An appropriate test for the investigation is, One sample t-test for sample mean. So option B is correct
What is a random sample ?The process of selecting a sample of data from a population in order to draw conclusions about the population is known as random sampling. Additionally known as probability sampling. Non-probability sampling, often known as non-random sampling, is this sample's opposite. Simple random sampling, stratified sampling, cluster sampling, and multistage sampling are the main forms of this sampling. Convenience samples are often referred to as non-arbitrary samples in sampling methodologies.
Given that,
Population mean = $100
Sample = n = 56
Sample mean = $102.30
sample standard deviation = $5.30
So, all the data mean, standard deviation is given
therefore, t-test used and one type of sample used as well
Hence, It is one-sample t-test for sample mean

tell me if the statement below is sometimes, always, or never true. justify your reasoning, (the Expressions x - 3 + y -3 represent the same value.)
Answers
Answer:
Sometimes true. It may be true at times if x or y equal each other, but if they do not equal each other it is not true
Step-by-step explanation:
We are given two expressions: x -3 and y - 3
Here x and y are two different variables.
These expressions are equal, when the value of x and the value of y are equal.
x - 3 = y -3 if x = y.
Therefore, the two expressions have the same value in sometimes.
That is, when x = y, then the value of two expressions are the same.
Example.
If x = 2 and y = 2, then
x - 3 = y - 3
2 - 3 = 2 - 3
-1 = -1
If they have different values, for x = 2 and y = 3
x - 3 = y - 3
2 - 3 = 3 -3
-1 = 0
Which is not true.
Therefore, the answer is sometimes.
