On multiple-Choice history Test, rita received a mark of 80%. She answer 32 correctly
Let total number of questions be x.
According to the question,
80% of x is 32
or 80/100 × x = 32
or x = 32 ÷ 80/100
or x = 32 × 100/80
or x = 32 × 10/8
or x = 4 × 10
or x = 40
So, total number of questions is 40.

7. Of the three explanations below, which person gives the best explanation of why the LSRL is the best line of best fit?
Explain your choice.
Thomas: The LSRL is the best line of
best fit because it touches the most
points on a scatterplot when graphed.
Keene: The LSRL is the best line of best fit
because it has the smallest value for all the
squared residuals added together.
Ella: The LSRL is the best line of best fit because the sum of the residuals is closest to zero when they are all
added together.
Answer:
Ella
Step-by-step explanation:
IT goes more into detail on why the LSRL is best line of fit

Identify the property on this equation 5(a + 3b) = 5a + 15b
Answer:
??????????????????????
Step-by-step explanation:
Answer: Distributive Property
The term "distribution" is also used in place of "distributive"
This property says
x*(y+z) = x*y + x*z
We multiply the outer term x with each inner term (y and z). Then we add the results.
In this case,
x = 5
y = a
z = 3b
So,
5(a+3b) = 5*a + 5*3b = 5a+15b

Step-by-step explanation:
Find the area of this parallelogram.
5 cm height
7 cm width
Answer:
35 cm^2
Step-by-step explanation:
To find the area you need to find the width and height which we have.
Now all you need to do is to use the formula Height x Width= area
so replace height with 5 cm and width with 7 cm
5 cm x 7 cm = area
5 times 7 is 35 so the area of the parallelogram is 35 cm^2 (cm times cm is cm^2)
Hope this helps!
Answer:
its either 35 or 70
Step-by-step explanation:
multiply 5 and 7 to get 35 or multiply 5 x 7 twice and get 70 pls mark brainliest me nub
10t-19=7t-14
what does t=
Answer:
t = [tex]\frac{5}{3}[/tex]
Step-by-step explanation:
10t - 19 = 7t - 14
Subtract 7t from both sides;
3t - 19 = -14
Add 19 to both sides;
3t = 5
Divide both sides by 3;
t = [tex]\frac{5}{3}[/tex]
Mr. Richard plans to take 25 students on a school trip. They plan to go to Zoo. The bus fee is $100 for the entire trip. Entrance fee is $2.50 per person. How much should each student pay? Note: Mr. Richard does not need to pay.
Answer:
$162.50
Step-by-step explanation:
+$100
25x2.50= $62.50
+$62.50
100+62.50=162.50
Answer:
Each student should pay $6.50
Step-by-step explanation:
The question is not very clear.
If Mr. Richard has to pay to enter:
Total cost = $100 + ($2.50×26) = $165
Cost per student = [tex]\frac{165}{25}[/tex] = $6.60
Each student should pay $6.60
If Mr. Richard doesn't have to pay to enter:
Total cost = $100 + ($2.50×25) = $162.5
Cost per student = [tex]\frac{162.5}{25}[/tex] = $6.50
Each student should pay $6.50

Olivia went to buy shoes at the mall. The shoes cost $55. If tax was 8%, how much did Olivia pay in all? i don't understand it
Answer:
$59.40
Step-by-step explanation:
8% is equal to 0.08
since you are adding the tax to the original cost you will multiply 55 by 1.08 to get the cost of the shoes plus the tax.
Answer:
55 times .8 =44$
Step-by-step explanation:
A line with a positive slope is parallel to one of the lines shown. What is its slope? Use the graph shown below.
Answer:
2/5
Step-by-step explanation:
first select the line that is positive which is the purple one
slope = change in y / change in x
two clear points are (0,2) and (5,4)
so you do y2-y1 / x2-x1
=(4-2)/(5-0)
=2/5
so the slope is 2/5

Which of the following polynomial functions is graphed below?
Answer: B. f(x)=(x+4)(x-2)^2(x+3)
Step-by-step explanation:
in the graph there's two negative x value and one positive x value
so the function should be in a form of f(x)= (x+a) (x-b)^2 (x+c)
the one with negative value has a square, (x-b)^{2}, because that's where the y = 0 (the point is hitting the (x,0))
Answer: B
