Answer:

1. How many hours do you spend on studying on Saturday?

2.How many hours do you spend on playing game on Saturday?

Step-by-step explanation:

I think your question is missed of key information, allow me to add in and hope it will fit the original one.  Please have a look at the attached photo.

My answer:

Statistical questions means that when you ask, you expect to have the variety of answers. Because each person will give different answer.

Two statistical questions that Evan could have asked to get his results are;

1. How many hours do you spend on studying on Saturday?

2.How many hours do you spend on playing game on Saturday?

Evan could not have asked a non-statistical question to get his results because there is only on answer and you expect the same answer from everyone you ask.

For ex: how many students spend 3 hours studying, the answer is only one, it is 2 in  Evan survey.

Which expression is NOT equal to 125? (1 point)
DENIUS [597]
Choice 1:
= 5 * [5^3 / (2/5)]^2
= by looking at the equation, it's kinda not equal to 125

choice 2:
= [5^3 / 5^4]^-3
= 5^-9 / 5^-12
= 5^(-9 - -12)
= 5^3
= 125

choice 3:
= 5^-2 / 5^-5
= 5^(-2 - -5)
= 5^3
= 125

choice 4:
= 5 * 5^5/5^3
= 5 * 5^(5-3)
= 5 * 5^2
= 5^3
= 125

So the expression that is not equal to 125 is:
<span>5 times the quotient 5 cubed over two-fifths, raised to the second power</span>

What does the slope of the line represent?​
Rashid [163]

Answer:

For each hour Cara works, she earns $10.

Step-by-step explanation:

You could see that on the graph that for 5 hours Cara has worked, she earns 50 dollars. The slope would be 50/5. 50/5 is equal to 10/1 through dividing so Cara earns $10 for each hour she works.

What are three rational numbers between -1 and -2
MArishka [77]

well, rational = fractional, namely something you can write as a fraction, well, anything between -1 and -2 is just less than -1 so

\bf \boxed{-2}\dotfill \stackrel{-1-\frac{1}{4}}{-\cfrac{5}{4}}\dotfill\stackrel{-1-\frac{1}{10}}{-\cfrac{11}{10}}\dotfill \stackrel{-1-\frac{1}{99}}{-\cfrac{100}{99}}\dotfill \boxed{-1}

Use the quadratic formula to solve the equation. If necessary, round to the nearest hundredth.
DaniilM [7]
A ) h = -16 t² + 135 t + 76
Let : h = 0
0 = - 16 t² + 135 t + 76
B ) t 1/2 = (-b+/- √ ( b² - 4 ac ) / ( 2 a )
t 1/2 = (-135 - √(18,225 + 4,864))/ (-32) = ( - 135 - 151.95) / (- 32)=
= (-286.95) / (- 32) = 9.967 ≈ 9.0 s ( other solution is negative )
Answer:
2)  0 = -16 t² + 135 t + 76;  9 s
