Answer:
x*90= your answer.
Step-by-step explanation:
X being however many test scores there are.
If you have 4 test scores, you would multiply 4*90=360
If you had 3 test scores, you would do it again, 3*90=270.
And so on. Because the test scores number wasn't listed, I provided some answers on how to solve it.

How many groups of 2 are in 7 explain your answer
Answer :
32 ÷ 7 = 3
But the The One haven't Group
The number of the group of 2 in the 7 is 3.
A numeral system is a writing system for expressing numbers; that is, a mathematical notation for representing numbers of a given set in a consistent manner using digits or other symbols. In different numeral systems, the same sequence of symbols can represent different numbers.
Given that the numbers are 7 and 2. The number of the groups of the 2 in the 7 will be calculated as,
Number = 7 / 2
Number = 3¹/₂
Number = 3
Therefore, the number of the group of 2 in the 7 is 3.

How many cubes with side lengths of 1/3 does it take to fill the prism?
5/3 x 4/3 x 2
Answer:
5 cubes by 4 cubes by 6 cubes
Step-by-step explanation:
Vp = 5/3 * 4/3 * 2 = 40/9 in^3.
Vc = (1/3)^3 = 1/27 in^3.
Vp/Vc = (40/9)/(1/27) = 40/9 * 27/1 = 120 Cubes.

A room has a length of 3.5 ft and a width of 5 feet. What is the area and perimeter of the room?
Answer:
17 feet
Step-by-step explanation:
add up all the sides. 3.5+3.5+5+5=17

Five gentlemen went to Molesky’s restaurant for all-you-can-eat wings. Mr. Andreasen ate 6 wings, Mr. Betz ate 24 wings, Mr. Henricksen ate 18 wings, Mr. Osters ate 20 wings, and Mr. Tyson ate 32 wings.
List all 10 possible SRSs of size n = 2, calculate the mean number of wings eaten for each sample, and display the sampling distribution of the sample mean on a dotplot.
Is the sample mean an unbiased estimator of the population mean? Justify your answer.
If we increase the sample size, does the variability of the sampling distribution change? Explain
The sampling computed simply illustrates that the population mean will be 20.
How to solve the samplingIt should be noted that the population mean will be calculated thus:
= (6 + 24 + 18 + 20 + 32)/5
= 100/5
= 20
It can be deduced that the sample mean is an unbiased estimator of the population mean.
Lastly, when there's an increase in the sample size, the variability of the sampling distribution change. This is because there's a reduction.

find the equation of P(0,4) Q(2,0)
Answer:
y = -2x + 4
Step-by-step explanation:
y / 4 = x - 2 / -2
-2y = 4(x - 2)
-y = 2(x - 2)
-y = 2x - 4
y = -2x + 4
»(y + 0)/4 = (x - 2)/(0 - 2)
»y/4 = (x - 2)/(-2)
»-2y = 4(x - 2)
»-2y = 4x - 8
»y = -4x - 8/(-2)
»y = -2x + 4✅

Solution:
To find the mean, add the set of data. Then divide it by the number of terms in the data.
1. Add the terms in the data.
[tex]\rightarrow \frac{1}{2} + \frac{1}{3} + \frac{2}{3} + 1\frac{1}{2}\\\\\ \rightarrow \frac{3}{6} + \frac{2}{6} + \frac{4}{6} + \frac{3}{2} \\\\ \rightarrow \frac{3}{6} + \frac{2}{6} + \frac{4}{6} + \frac{9}{6} \\\\ \rightarrow \frac{18}{6} = 3[/tex]
Divide 3 by 4 since there is 4 terms in the data.
2. Divide the "added" data by 4 since there is 4 terms.
[tex]\rightarrow Mean \ of \ data \ set = 3 \div4[/tex]

Now,
Length = 2/3 (Given)Width = 3/4 (Given)Solve ;

➪ Thus, The carpet takes up 1/2 unit² area of the classroom...~
Answer:
1/2 or half of the classroom area
Step-by-step explanation:
Step 1: Calculating area of carpet
Let total length be l and width be w.
Now, according to the problem,
Area = 2l/3 x 3w/4
= 2lw/4
Step 2: Take area of carpet and area of classroom as a ratio
(2lw/4) / lw
= 2/4
= 1/2
Therefore, the carpet takes up 1/2 or half of the classroom area.

Compare the volumes of the right prism and the oblique prism. Explain.
Look at the picture to answer.
Also this is worth 100 points(you get 50, and more if your answer is good and I Brainliest you (if that makes any sense))
Answer:
Both of the volumes are equal.
Step-by-step explanation:
Since both figures have the same base and have the same heights, the figures have equal volumes. If the height of the oblique prism was not outside of the figure and was instead the diagonal line, the volumes would not be the same. Rectangular prisms and oblique prisms are only equal when their bases (l*w) and the heights are equal, and the heights are only equal if the height of the oblique prism is outside of the figure, as shown in the image.
Answer:
They are the same.
Step-by-step explanation:
Since the height of the slanted prism is the same height as the regular one, the volumes work out. Even if slanted the formula is STILL lengthxwidthxheight.
