PLEASE HELP BABES!!
Michael’s grandmother made two pies for Thanksgiving, a sweet potato pie and a chocolate pie. Each pie had 8 slices. All of the sweet potato pie and 2 slices of the chocolate pie were eaten.
How much pie did Michael’s family eat on Thanksgiving?
A) 5/8 pie
B) 10/16 pie
C) 1 1/4 pie
D) 1 3/8 pie
Michael's family ate all of the sweet potato pie (8 slices) and 2 slices of the chocolate pie, making it a total of 10 slices eaten. Each pie has 8 slices, so they consumed 1 and 1/4 pies in total, which corresponds to answer choice C) 1 1/4 pie.
To find out how much pie Michael's family ate on Thanksgiving, we need to consider that the sweet potato pie had 8 slices and the chocolate pie also had 8 slices. All of the sweet potato pie was eaten, this means 8 slices of pie were consumed. From the chocolate pie, only 2 slices were eaten. To get the total number of slices eaten, we add the slices of sweet potato pie to the slices of chocolate pie that were eaten.
Total slices eaten = Slices of sweet potato pie + Slices of chocolate pie eaten
= 8 slices + 2 slices
= 10 slices
Since each pie was divided into 8 slices, we can see that the total pie eaten in terms of whole pies is:
Total pie eaten = 10 slices \/ 8 (slices per pie)
1 and 2 \/ 8
Since 2 \/ 8 can be simplified to 1 \/ 4, we get:
Total pie eaten = 1 and 1 \/ 4 pies
Therefore, the correct answer is C) 1 1 \/ 4 pie.

A manager of a grocery store wants to determine if consumers are spending more than the national average. The national average is $150.00 with a standard deviation of $30.20. The manager collects 40 random receipts and finds that the average is $160. Complete a hypothesis test with a significance level of 2.5% to determine if the average customer spends more in his store than the national average. Which of the following is a valid conclusion for the manager based on this test?
Answer:
We conclude that consumers are spending more than the national average.
Step-by-step explanation:
We are given the following in the question:
Population mean, μ = $150.00
Sample mean, [tex]\bar{x}[/tex] = $160
Sample size, n = 40
Alpha, α = 0.025
Population standard deviation, σ = $30.20
First, we design the null and the alternate hypothesis
[tex]H_{0}: \mu = 150\text{ dollars}\\H_A: \mu > 150\text{ dollars}[/tex]
We use One-tailed z test to perform this hypothesis.
Formula:
[tex]z_{stat} = \displaystyle\frac{\bar{x} - \mu}{\frac{\sigma}{\sqrt{n}} }[/tex]
Putting all the values, we have
[tex]z_{stat} = \displaystyle\frac{160 - 150}{\frac{30.20}{\sqrt{40}} } = 2.0942[/tex]
Now, [tex]z_{critical} \text{ at 0.025 level of significance for one tailed test } = 1.96[/tex]
Since,
[tex]z_{stat} > z_{critical}[/tex]
We reject the null hypothesis and accept the alternate hypothesis. We conclude that consumers are spending more than the national average.

Graph. y−5=43(x−5)
Solution:
The given equation of line is :
→ y- 5 = 43 (x -5)
= y -5 = 43 x - 43 × 5 → [Using distributive property]
= y- 5 = 43 x - 215
→ 43 x - y - 215 +5 =0
→ 43 x - y -210 =0
→ y = 43 x - 210
As the slope of line→y = m x + c is ,43.
Or , tan A = 43, where A is the angle made by line in positive direction of X axis.
And Y intercept = -210

Which statements are true?
Select each correct answer.
Answer:
As, there are 595 students in the school.
To find the mean number of books, read by student in the school during summer
If he will survey all the students in the school that will give the exact mean , but that will be little lengthy and tedious.
As, well as larger the number of students surveyed , the better the mean is.
But option A, is true as, select randomly few students , find the mean number of books read by them , that will be less time consuming and gives the mean of population also.
Option A:
To estimate the mean using sample,Terrance will need to randomly select students, he will survey and that represents population as well.
Apart from option A,option B is also true.

Answer: Yes, the quadrilateral ABCD is a trapezoid.
Step-by-step explanation: Given that the vertices of the quadrilateral ABCD are A(–4, –5), B(–3, 0), C(0, 2), and D(5, 1).
We are to determine whether ABCD is a trapezoid or not.
We know that a trapezoid is a quadrilateral with one pair of opposite sides parallel. Also, the slopes of two parallel lines are equal.
First, we will find the slopes of the sides AB, BC, CD and DA.
We have
[tex]\textup{Step 1: The slope of AB}=\dfrac{0+5}{-3+4}=\dfrac{5}{1}=5,\\\\\textup{Step 2: The slope of BC}=\dfrac{2-0}{0+3}=\dfrac{2}{3},\\\\\textup{Step 3: The slope of CD}=\dfrac{1-2}{5-0}=-\dfrac{1}{5},\\\\\textup{Step 4: The slope of DA}=\dfrac{-5-1}{-4-5}=\dfrac{2}{3}.[/tex]
Since the slopes of the sides BC and DA are equal, so BC an DA are the parallel sides of the quadrilateral ABCD.
Thus, the quadrilateral is a trapezoid because it has a pair of opposite sides parallel.
The quadrilateral is a trapezoid because it contains two opposite sides that are parallel, the quadrilateral is called a trapezoid.
What is a trapezoid?It is defined as the quadrilateral having four sides in which two sides are parallel to each other, it is a 2-dimensional geometry.
We have:
Quadrilateral ABCD with vertices A(–4, –5), B(–3, 0), C(0, 2), and D(5, 1)
To identify the quadrilateral is a trapezoid we must find the slopes of the lines AB, BC, Cd, and AD
For slope m the formula is given by:
[tex]\rm m = \frac{y_2-y_1}{x_2-x_1}[/tex]
For slope of AB:
[tex]=\rm \frac{0-(-5)}{-3-(-4)}[/tex]
[tex]=\rm \frac{0+5}{-3+4}[/tex]
= 5
For slope of BC:
[tex]=\rm \frac{2-0}{0-(-3)}[/tex]
[tex]=\rm \frac{2}{3}[/tex]
For slope of CD:
[tex]=\rm \frac{1-2}{5-0}[/tex]
= -1/5
For slope of AD:
[tex]=\rm \frac{-5-1}{-4-5}[/tex]
= 2/3
Because the slopes of the sides BC and DA are equivalent, BC and DA are the quadrilateral ABCD's parallel sides.
Thus, the quadrilateral is a trapezoid because it contains two opposite sides that are parallel, the quadrilateral is called a trapezoid.

the family arcade center charges an entry fee of 11$ plus an additional 1$ per game played
Answer:
Option (c) is correct.
Average expense is given by function [tex]C(x)=\frac{\$11+\$1x}{x}[/tex]
Step-by-step explanation:
Given : The family arcade center charges an entry fee of 11$ plus an additional $1 per game played.
We have to choose from the given options a function that describes the average expense for a player per game played.
Let x be the number of game played.
So, The entry fee will be same for all that is $ 11
And in addition $1 is charged per game played.
when they play x games the charge will be $1 × x = $ x
Thus,
Average expense is defined as the total charge divided by number of player per game played.
That is Total charge per person = $ 11+ $1x
Since, there are x game played.
Thus, Average expense is given by function
[tex]C(x)=\frac{\$11+\$1x}{x}[/tex]
Express the polynomial z2 − z4 + 2z2 in standard form and then classify it.
Final answer:
The polynomial in standard form is z⁴ + 3z₂ which is a univariate quartic polynomial since the highest power of z is 4.
Explanation:
Expressing the Polynomial in Standard Form
To express the polynomial z² - z⁴ + 2z² in standard form, we combine like terms. The terms z² and 2z² are like terms, which means they can be added together. So, the polynomial in standard form is z⁴ + 3z².
Classification of the Polynomial
This is a quartic polynomial because the highest degree of the variable z is 4. In addition, there is only one variable, z, which makes it a univariate polynomial. Therefore, the correct classification of the polynomial is a univariate quartic polynomial.

The price per barrel of crude oil in constant 2008 dollars can be approximated by p(t) = 0.45t2 − 12t + 105 dollars. (0 ≤ t ≤ 28) where t is time in years since the start of 1980.† find p'(t) and p'(25).
The required p'(t) = 0.90t − 12 is and the value of p'(25) is 10.5.
What is function?A function from a set X to a set Y assigns to each element of X exactly one element of Y.
Now the given function is,
p(t) = 0.45t² − 12t + 105
where t is time in years
Taking first derivative we get,
p'(t) = 0.90t − 12
which is the required expression for p'(t)
Now for p'(25), put p = 25 in p'(t) we get,
p'(25) = 0.90*25 − 12
Solving,
p'(25) = 22.5 − 12
⇒ p'(25) = 10.5
which is the required value of p'(25).
Thus, the required p'(t) = 0.90t − 12 is and the value of p'(25) is 10.5.

Final answer:
To find the derivative of the price function with respect to time and the value of the derivative at a specific time, follow the steps provided using the given function p(t).
Explanation:
The derivative of the price function with respect to time, p'(t), can be found by taking the derivative of the given function, which is p'(t) = 0.90t - 12. The value of p'(25) can be calculated by substituting t = 25 into the derivative function, giving p'(25) = 0.90(25) - 12 = 22.5 dollars per year.
