At the football concessions stand, Tia sold 78 hamburgers and chicken tenders. If she
sold 24 more hamburgers than chicken tenders, how many hamburgers did she sell?
I am going to do this problem with more of an algebraic approach weather or not its the way your teacher wants you to do it like this.
The way to do things algebraically is to just set variables for what you want to find and set up equations to represent each sentence.
As seen there are hamburgers and chickens in this problem. So let's set the numbers of hamburgers to x, and the numbers of chickens to y.
Now write out each sentence using variables.
1.) Tia sold 78 hamburgers and chicken tenders.
x+y=78
2.) If she sold 24 more hamburgers than chicken tenders.
x=y+24
Now that we have the 2 equations, its time to solve.
Since we have x=y+24, we can replace the x in the first equation with the second equation
y+24+y=78
2y+24=78
Now we can subtract 24 from both sides.
2y=54
Simplify
y=27
Solve for x
x=27+24=51

10% of a number is 13. What is the number?
Answer:
130
Step-by-step explanation:
When finding 10% of a number just move the decimal over to the left once.
For example if your number is 150 you want to move the "decimal" over to the left once:
150 is the same as 150.0 so getting 10% gives you: 15.0
This means if you want to go the other way and find the number after already having 10% of the number then you want to move the decimal to the right. In this case:
13.0 would become 130.
13 is 10% of 130

Eslynn tracked her speeds and times she cycled on the weekend.
. Saturday, Eslynn traveled at an average speed of 24 miles per hour for 2.5 hours.
. Sunday, Eslynn traveled at an average speed of 30 miles per hour for 1.5 hours.
what was the total distance in miles Eslynn traveled on the weekend?
Answer: 30
Step-by-step explanation:
Example
x=y
x+z=y+z
If we subtract the same number from both sides of an equation, both sides will remain equal.
Example
x=y
x−z=y−z
If we divide both sides of an equation by the same number, both sides will remain equal.
Example
x=y
x÷z=y÷z
If we multiply both sides of an equation by the same number, both sides will remain equal.
x=y
x⋅z=y⋅z

Lin’s second pan has a lenght of 3/8 inches , a width of 15/4 inches , and a height of 3/2 inches. what the volume of the second pan?
expian
Answer:
the volume of the second pan is 15 cubic inches
Step-by-step explanation:
The computation of the volume of the second pan is shown below:
The volume is
= Length × width × height
= [tex]\frac{8}{3}\times \frac{15}{4}\times \frac{3}{2}[/tex]
= 15 cubic inches
hence, the volume of the second pan is 15 cubic inches

Alma is estimating the proportion of students in her school district who, in the past month, read at least 1 book. From a random sample of 50 students, she found that 32 students read at least 1 book last month. Assuming all conditions for Inference are met, which of the following defines a 90 percent confidence interval for the proportion of all students in her district who read at least 1 book last month?
A. 32 +1.645,√(32)(18/50)
B. 32+ 1.9620√ √(32)(18/50)
C. 0.64 + 1.282√(0.64 )(0.36)/ 50
D. 0.64 + 1.645√(0.64 )(0.36)/ 50
E. 0.64 + 1.96√(0.64 )(0.36)/ 50
Answer:
D)
[tex](0.64 +1.645 \sqrt{\frac{0.64(0.36)}{50} })[/tex]
90 percent confidence interval for the proportion of all students in her district who read at least 1 book last month
(0.52846 , 0.75166)
Step-by-step explanation:
Step:-1
Given that the random sample size 'n' = 50
The sample proportion
[tex]p^{-} = \frac{32}{50} = 0.64[/tex]
90 percent confidence interval for the proportion of all students in her district who read at least 1 book last month
[tex](p^{-} - Z_{0.90} \sqrt{\frac{p(1-p)}{n}, } , p^{-} +Z_{0.90} \sqrt{\frac{p(1-p)}{n} })[/tex]
Step(ii):-
Level of significance = 0.90
Z₀.₉₀ = 1.645
[tex](0.64 - 1.645 \sqrt{\frac{0.64(1-0.64)}{50}, } , 0.64 +1.645 \sqrt{\frac{0.64(1-0.64)}{50} })[/tex]
[tex](0.64 - 1.645 \sqrt{\frac{0.64(0.36)}{50}, } , 0.64 +1.645 \sqrt{\frac{0.64(0.36)}{50} })[/tex]
(0.64 -1.645(0.06788) , (0.64 + 1.645(0.06788)
(0.52846 , 0.75166)
Final answer:-
90 percent confidence interval for the proportion of all students in her district who read at least 1 book last month
(0.52846 , 0.75166)

[tex]x = 18.5[/tex]
[tex]y = 22.5[/tex]
[tex](b)[/tex]
[tex]x = 10[/tex]
Step-by-step explanation:
Solving (a):
7x - 19 and 3x + 14 are interior angles.
So:
[tex]7x - 19 + 3x +14 = 180[/tex]
Collect like terms
[tex]7x + 3x = 180 - 14 + 19[/tex]
[tex]10x = 185[/tex]
[tex]x = 18.5[/tex]
7x - 19 and 5y - 2 are equal angles --- corresponding angles
So:
[tex]5y - 2 = 7x - 19[/tex]
Make 5y the subject
[tex]5y = 7x - 19+2[/tex]
5y = 7x -17
Make y the subject
[tex]y = \frac{1}{5} (7x - 17)[/tex]
Substitute [tex]x = 18.5[/tex]
[tex]y = \frac{1}{5} (7*18.5 - 17)[/tex]
[tex]y = \frac{1}{5} (112.5)[/tex]
[tex]y = 22.5[/tex]
Solving (b):
The triangle is right-angled.
So:
[tex]5x + 3 + 2x + 17 + 90 = 180[/tex]
Collect Like Terms
[tex]5x + 2x = 180 - 90 - 17-3[/tex]
[tex]7x = 70[/tex]
[tex]x = 10[/tex]

Both values can be divided by 4
so the greatest common factor is 4
8/4=2
20/4=5
so the simplified version of the given expression is 2/5
The following list shows three factors that can either increase or decrease the probability of a Type II error.
The sample size is increased.
The significance level is increased.
The standard error is increased.
Which factors alone will cause the probability of a Type II error to increase?
A
I only
B
II only
C
III only
D
I and II only
E
I, II, and III
Answer:
C) III only
Step-by-step explanation:
An increase in standard error increases variability of the sampling distribution. Due to the increase in variability of the sampling distribution, it is more difficult to detect a true difference, and the probability of a Type II error is increased.
