Answer:
Correct option:
"The total cost of renting a jet ski for $25 per hour plus a fee of $50."
Step-by-step explanation:
Proportional relationships are associations between two variables where the ratio of these two variables are correspondent. Or, in a proportional relationship, one variable is a constant value times the other variable. This constant is known as the "constant of proportionality".
The first three options represents a proportional relationship.
But the last option does not.
"The total cost of renting a jet ski for $25 per hour plus a fee of $50."
That is,
TC = 25·<em>h</em> + 50
The relationship is linear not proportional.
Answer:
270
Step-by-step explanation:
72 ÷ 4 = 18
6 + 5 = 11
18 × 11 = 198
198 + 72 = 270
Answer:
Answer below!
Step-by-step explanation:
since y = -3x + 1, you can just plug those numbers in on the first equation.
6x + 2(-3x+1) = 2 (see how I replaced y into -3x + 1)
then distribute 2.
6x - 6x + 2 = 2, subtract 2 to both sides
6x - 6x = 0, combine x
0 = 0 (this means it has an infinite amount of solutions)
Answer:
The correct option is C) large sample size (n) with small variance.
Step-by-step explanation:
Consider the provided information.
It is given that the other factors are held constant, and we want the narrowest confidence interval for a population mean.
Confidence interval for a population mean is directly proportional to variance and inversely proportional to the sample size.
If we increase the variance, CI will increase. But we want the narrowest CI, so variance should be small.
As CI is inversely proportional to sample size, therefore if we increase the sample size CI will decrease.
Hence, the correct option is C) large sample size (n) with small variance.
