6. A pizza's original price is $11. It is on sale for $9.25. What percent off is it?
Solution:
We know that:
[tex]Original \ price = \$11[/tex]
[tex]Sale \ price = \$9.25[/tex]
[tex]\frac{9.25}{11} + \frac{1.75}{11} =100\%[/tex]
Simplify the equation to find the percent off:
[tex]\frac{9.25}{11} + \frac{1.75}{11} =100\%[/tex]
[tex]84\% + \bold{16\%} = 100\% \space\ \space\ \space\ \ \ \ \ [Rounded][/tex]

Step-by-step explanation:
A process that is considered to be in control measures an ingredient in ounces. Below are the last 10 samples (each of size n = 5) taken. The population process standard deviation is 1.36. Samples 1 2 3 4 5 6 7 8 9 10 9 13 13 11 11 10 9 13 7 9 8 11 9 11 10 10 12 11 7 12 9 12 9 12 10 7 11 7 13 10 10 14 11 10 10 13 9 9 12 7 13 12 10 10 9 9 10 8 10 13 a) Standard deviation of the sampling means = . 608 ounces (round your response to three decimal places). b) With z = 3, the control limits for the mean chart are: UCL Subscript x overbar = 12.124 ounces (round your response to three decimal places). LCL Subscript x overbar = 8.476 ounces (round your response to three decimal places). c) The control limits for the R-chart are: UCL Subscript Upper R = nothing ounces (round your response to three decimal places).
Answer:
Kindly check explanation
Step-by-step explanation:
Given the data:
Population standard deviation (σ) = 1.36
Sample size (n) = 5
A.)Standard deviation of sampling mean (σx) = (σ/√n)
(1.36/√5)
1.36 / 2.236
= 0.608
B.) With z = 3, the control limits for the mean
chart :
Control limit = m ± zσx
Using calculator ; mean (m) of the data = 10.40
Lower control limit : 10.4 - 3(0.608) = 8.576
Upper Control limit : 10.4 + 3(0.608) = 12.224
The control limit for the range :
Average value of range(R) in the sample = 3.6
Lower Control limit : R*D3
Upper control limit: R*D4
From the range chart table :
D3 = 0 ; D4 = 2.114
Lower Control limit : R*D3 = 3.6(0) = 0
Upper control limit: R*D4 = 3.6(2.114) = 7.61
The length of a rectangle is five times its width.
If the area of the rectangle is 405cm^2, find perimeter
Answer:
108
Step-by-step explanation:
Let's say the width is x
Of the length is 5 times the width, then the length is 5x
Area = length * width
405 = x * 5x
405 = 5x^2
405/5 = 5x^2/5
81 = x^2
Take the square root of both sides
2/[81 = 2/[x^2
9 = x = width
9 × 5 = 45 = length
Perimeter = 2 × length + 2 × width
2 × 45 + 2 × 9
90 + 18 = 108

Brianna asked 45 students if they would vote for her to be student council president. She used her calculator to compare the number of students who said yes with the total number of students. Her calculator showed the result as 0.6222...
1. Write this number as a fraction (Steps)
2. How many students said they would vote for Brianna?
Answer:
Kindly check explanation
Step-by-step explanation:
Given the following :
Total number of students = 45
Proportion of those who said yes to the total number of students = 0.62222...
1.) writing 0.622222... as a decimal
0.62222 / 1
Multiply numerator and denominatior by 100000 to get rid of the decimal
62222/100000
= 31111 / 50000
Let number who said yes = y
Then,
y / 45 = 31111/50000
50000y = 1399995
y = 1399995 / 50000
y = 27.999
y = 28

Find the slope then describe what it means in terms of the rate of change of the dependent variable per unit change in the independent variable. The linear function f(x)=4.1x+26 represents the percentage of people, f(x), who graduated from college x years after 1998
Answer:
Kindly check explanation
Step-by-step explanation:
Given the linear function: f(x)=4.1x+26
Comparing the equation with the general linear regression Equation :
f(x) = mx + c
Where ;
m = slope ; x = independent variable ; c = intercept
Hence, the slope of the equation is 4.1
The expression goes those; the dependent variable y increases by 4.1 per 1 degree increase in the dependent variable.

Because 10 lies between two consecutive perfect squares, Choose... , 10−−√ is located between the Choose... of these two numbers. This means that 10−−√ is located between Choose... , so 10−−√ is Choose... 5.
Answer:
[tex]\sqrt{10} < 5[/tex]
Step-by-step explanation:
Given
[tex]\sqrt{10}[/tex] ___ [tex]5[/tex]
Required
Fill in the gap
First, we need to solve [tex]\sqrt{10}[/tex]
[tex]\sqrt{10}= 3.162[/tex]
So:
[tex]\sqrt{10}[/tex] ___ [tex]5[/tex]
becomes
3.162 ___ 5
3.162 lies between 3 and 4
So, we can say that
[tex]\sqrt{10}[/tex] lies between 3 and 4
Since:
3.162 is less than 5, the gap can be filled with <.
So, we have: 3.162 < 5

Area= 12(8)= 96 ft²
Rectangle B
Length= 3 ft
Breadth= 3 +8= 11 ft
Area= 3(11)= 33 ft²

Complete Question
A baseball team had $1,000 to spend on supplies. The team spent $185 on a new bat. New baseballs cost $4 each.
The inequality 185 + 4b ≤ 1,000 can be used to determine the number of new baseballs (b) that the team can
purchase. Which statement about the number of new baseballs that can be purchased is true?
A. The team can purchase 204 new baseballs.
B. The minimum number of new baseballs that can be purchased is 185.
C. The maximum number of new baseballs that can be purchased is 185.
D. The team can purchase 185 new baseballs, but this number is neither the
maximum nor the minimum.
Answer:
D. The team can purchase 185 new baseballs, but this number is neither the maximum nor the minimum.
Step-by-step explanation:
The first step would be to solve the given equation:
185 + 4b ≤ 1000
4b ≤ 1000 - 185
4b ≤ 815
Divide both sides by 4
b ≤ 203.75
The maximum amount of baseballs the team can buy is 203. This means that they can buy 203 or less than that amount.
Of all the options give, option D is the correct option because the team can purchase 185 new baseballs, but this number is neither the maximum nor the minimum.
The maximum number of ball they can buy is 203 balls and the minimum is zero.
