Answer:

1) the number of hours of TV watched

2)  quantitative

3) Mean or Median

Completed details of Question

Additional details to the question are as below

1) Identify the variable measured on each student.

2) Is the variable categorical or quantitative?

3) Identify two statistics that the student could use to summarize the variable.

a) Mean or Median

b) Mean or Proportions

c) Mean or Mode

d) Median or Mode.

Explanation to the answer:

1) The variable measured on each student is the number of hours of TV watched

2) The variable is the amount of time, therefore it is quantitative.

3)  Quantitative data can be used compare the exact size and extent of difference in two quantities. Therefore, the two statistics that the student could use to summarize the variables would be Mean or Median. Mean will be the average time and Median will be the middle when the amount of time is ordered from least to greatest.

Answer:

x = 72

Step-by-step explanation:

<u>To solve for 'x', isolate it</u>. This means to keep 'x' on one side of the equal sign, while moving the other numbers to the other side. The numbers on the other side will tell you what 'x' equals to.

<u>When 'moving' a number to the other side, you cancel it out where it originally is by doing reverse operations</u>. (Reverse operation pairs are addition/subtraction and division/multiplication). To keep an equation balanced, <u>what you do to one side you have to do to the other</u>.

\frac{3}{8}x-17=10        Keep 'x' on the left and move everything over.

\frac{3}{8}x-17+17=10+17        Add 17 to both sides. "-17" cancels out on the left.

\frac{3}{8}x=27        Simplified right side

\frac{3}{8}x/\frac{3}{8}=27/\frac{3}{8}        Because 3/8 originally multiplies with 'x', do the reverse: divide both sides by 3/8.

x=27/\frac{3}{8}        To divide a fraction, change to multiplication and flip the fraction's top and bottom numbers.

x=27*\frac{8}{3}        Combine the factors into one fraction.

x=\frac{27*8}{3}        Multiply 27 by 8 in the numerator.

x=\frac{216}{3}        Simplify the fraction by dividing top by bottom.

x=72        Final answer, solved for 'x'

-5a + 15/2a - 25 = 53.2 + 21.8​
dedylja [7]

Answer:

a= 40

Step-by-step explanation:

-5a + 7.5a - 25 = 53.2 + 21.8​

add like terms on both sides: 2.5a - 25 = 75

add 25 on both sides: 2.5a = 100

divide both sides by 2.5: a = 40

What is the perimeter of quadrilateral A' B' C' D'?
Aneli [31]

Answer:

14.2 Units

Step-by-step explanation:

The second shape is given to confuse you and is not actually necessary.

To work out the perimeter of an irregular shape you simply add up the lengths of each side. The shape you have here is an irregular quadrilateral as it has four corners and no recognisable/coarrale organisation.

1.4units + 2.2units + 4.5units +6.1units = 14.2 units.

I hope this helps :)

Please help kind of confusing
Rom4ik [11]
Well, if earth's climate is getting warmer then the glaciers would probably start to melt. I'm not sure how to answer the second one either, maybe since glaciers are so big, they would be a lot of animals living on them and they would loose their habitat maybe causing them to have to move somewhere else?

Surface Area using the net.
Hitman42 [59]

Step-by-step explanation:

step 1. very tough question! you need the slant height (h)

step 2. h = sqr(8^2 + 3^2) = sqr(73) sqr is the square root

step 3. SA = B + ph/2 where SA is the surface area, B is the base area, and p = the lateral perimeter

step 4. we will call the hypotenuse of the right triangle c

step 5. c = sqr(13^2 + 6^2) = sqr(205)

step 6. SA = (1/2)13(6) + (13 + 6 + sqr(205))sqr(73)/2

step 7. SA = 39+ (33.3178)(8.5440)/2 = 181.3336 cm^2.
