Answer: zoe's question's data would vary because not everyone in her class could play video games for the exact same amount of time.
however this is not a statistical question because we do not know when the students are playing video game for example we wouldnt know if she wanted to know how much time a classmates spends playing video games each year, each month, each week, etc. so to make this a statistical question zoe would have to ask.... which student spends the most time a day on video games.
hope this helps ;D
Step-by-step explanation:
How many students are less than 69 inches in height
19
22
25
17
The number of students whose height less than 69" = 19
Hence option first is correct,
According to the given tally chart,
We can see that,
Frequency for height 65" = 1
Frequency for height 66" = 1
Frequency for height 67" = 9
Frequency for height 68" = 8
Since we have to calculate the number of students having height less than 69"
Therefore, neglect the other frequencies.
Now sum up the above frequencies,
= 1 + 1 + 9 + 8
= 19
Hence,
There are 19 students having height less than 69".

Answer:
3. Yes it is possible to fall out of the "average" high statistics. It does not make you not a man or woman, but it just means you are taller or shorter than average for your gender.

PYTHAGOREAN THEOREM
Answer:
8. 20.8 units
9. isosceles
Step-by-step explanation:
8.The vertical altitude line divides the triangle into two congruent right triangles. Each has a horizontal leg of 4 units, and a vertical leg of 5 units. (You can find these lengths by subtracting coordinates, or by counting grid squares.)
slant sides
The hpotenuses of these right triangles are the short sides (PR, QR) of the larger triangle PQR. We can find their length using the Pythagorean theorem. Defining S as point (-2, -1), we have ...
PS² +SR² = PR² . . . . . . . . . . . . the Pythagorean theorem relation
4² +5² = PR² = 16 +25 = 41 . . . with numbers filled in
PR = √41 . . . . . . . . . . . . . . take the square root
PR ≈ 6.4 . . . . . . . . . . . round to tenths
horizontal side
The length of side PQ is 8 units, found by subtracting x coordinates ((2 -(-6)) = 8), by counting grid squares, or by doubling the length of PS (2(4) = 8).
perimeter
The perimeter of the triangle is the sum of its side lengths:
perimter = PR +QR +PQ = 6.4 +6.4 +8 = 20.8
The perimter of triangle PQR is 20.8 units.
__
9.Sides PR and QR are congruent, so the triangle is isosceles.

Luke went shopping for a new pair of pants. The listed price of the pair of pants was $21, but the price with tax came to $22.05. Find the percent sales tax.
Answer:
5%
Step-by-step explanation:
22.05-21=1.05
1.05/21=.05
.05*100=5%
The sales tax is 5% of listed price.
What is a percentage?A ratio or value that may be stated as a fraction of 100 is called a percentage. And it is represented by the symbol '%'.
Given, Luke went shopping for a new pair of pants.
The listed price of the pair of pants was $21.
But the price with tax came to $22.05.
The taxed amount
= $22.05 - $21
= $1.05
To find the percentage of taxed amount:
We use the percentage formula,
let m be the required percentage.
So,
1.05 = m x 21 /100
m = 1.05 x 100 / 21
m = 105 /21
m = 5%
Therefore, taxed amount is 5% of original price.

Answer:
40.5 in²
Step-by-step explanation:
It's pretty easy if you find the surface area of each and every shape alone first.
I see 2 squares and 4 rectangles.
Let's start by finding the surface area of the squares:
-The formula to finding the area of a square is length x length.
L×L
1.5 in x 1.5 in= 2.25 in²
2.25 in is the surface area of 1 square
but we have two squares so you do 2.25 in × 2 to get the surface area of both squares.
2.25 in² × 2= 4.5 in² (this is the surface area of both squares)
Now we calculate the surface area of the four rectangles.
Formula: L×W (length × width)
6 in × 1.5 in = 9 in² (s.a of one rectangle)
Since we have four rectangles, we'll have to multiply it by 4
9 in² × 4= 36 in²
Now we add the total surface areas of both the squares and the rectangles.
4.5 in² + 36 in²= 40.5 in²
Sorry, I know it's too wordy ✌

Use the net to find the surface area of the regular pyramid.
Answer:
7 or [tex]7^{2}[/tex]
Step-by-step explanation:
Each triangle has the surface area of 1.5, because 1 [tex]*[/tex] 3 = 3 / 2 = 1.5. You divide by two because it is half a rectangle instead of a full one. You multiply by four which would get you 1.5 [tex]*[/tex] 4 = 6. The square in the middle has the surface area of 1 because 1 [tex]*[/tex] 1 = 1. So you would get 7.
