Answer:
median 53
range 69
mode all values appear once
Step-by-step explanation:
7x+3y=-1
x+y=-3
8x+4y=-4
2x+y=-1
y=-1-2x
x+y=-3
x-1-2x=-3
-x=-2
x=2
y=-1-2*2=-1-4=-5
Answer:
- Implied population is all listeners of the radio talk show
- the variable is opinion of a listener
- Yes, bias is voluntary response. Those with the strongest opinions are most likely to call in.
Step-by-step explanation:
Radio talk show host asked listeners to respond therefore the population is all listeners of the radio talk show.
The variable is the response "yes" or "no"
There is voluntary response bias, because the respondents are volunteered to answer, therefore sample is consisted of self-selected listeners.
Answer:
E. 2.
Step-by-step explanation:
The sphere will have a diameter equal to the side length of the cube.
The side length of the cube is ∛64 = 4 so the diameter of the sphere = 4.
The radius = 1/2 * 4 = 2.
Your answer will be x • 4³ = 64x
When simplifying powers, the rule is that if you’re dividing two powers with the same base (in this case the base is 4), you need to subtract the powers. For example, 3³ ÷ 3² = 3 (which is 3^1).
Using this rule, we can see that 4^8 ÷ 4^5 = 4^(8-5) = 4³.
The x is on top of the fraction and we’re not dividing by an x, so it doesn’t change. Therefore your final answer is 64x.
I hope this helps!
