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.
I think 5x23x2=23x5x2=23x10=230 the property is the associativity
|-6 1/2|, |-1|, |0|, |9|, these are simply going from smallest to largest, once you get past 0 on a number line it goes back by one, for example 0,-1,-2,-3 and so forth, don’t think of negatives like whole numbers
Answer:
The expression for her balance is "B(t) = -75*t + 1500". It'll take her 20 months to pay off the loan.
Step-by-step explanation:
We are looking for a function that has the following points:
B(0) = 1500
B(4) = 1200
B(7) = 975
Between B(4) and B(7), there was a variation of 3 months and a variation of -225 on her balance, thefore for each month that passed there was a variation of -75. Thefore, the expression for her ballance is:
B(t) = -75*t + 1500
To check if this expression is valid, we will apply the values provided on the problem:
B(0) = -75*0 + 1500 = 1500 (valid)
B(4) = -75*4 + 1500 = -300 + 1500 = 1200 (valid)
B(7) = -75*7 + 1500 = -525 + 1500 = 975 (valid)
When she pays of her loan, B(t) = 0, so we need to solve for t as shown below:
B(t) = -75*t + 1500 = 0
-75*t + 1500 = 0
75*t = 1500
t = 1500 / 75 = 20 months
It'll take her 20 months to pay the loan.
Answer:
Junk gets 72
Step-by-step explanation:
Leah: Junko: total
1 8 1+8 = 9
The total is 81
81/9 = 9
Multiply each part by 9
Leah: Junko: total
1*9 8*9 9*9
9 72 81
