Suppose the null hypothesis is rejected. State the conclusion based on the results of the test. Six years ago, 11.2% of registered births were to teenage mothers. A sociologist believes that the percentage has increased since then. Which of the following is the correct conclusion? A. There is sufficient evidence to conclude that the percentage of teenage mothers has increased. B. There is not sufficient evidence to conclude that the percentage of teenage mothers has remained the same. C. There is not sufficient evidence to conclude that the percentage of teenage mothers has increased. D. There is sufficient evidence to conclude that the percentage of teenage mothers has remained the same.

1) 2/5

2) zero=0/1

3) zero=0/2

4) -4/5

5) undefined=3/0

answer: 7 x 2/5 = 2.8 hours, is your answer. your welcome! : 3

step-by-step explanation: first work out how long it took to hose 1/7 of the lawn which is 2/5 hours. times that by 7 to get the whole lawn.

sorry i don't know the other answer. i didn't learn what a proportional relationship is.

let f (x ) is a function and c be a positive real number,   the graph of the function g (x ) = f (cx ) is represented as follows.

when, c > 1,   the function compresses it in the x - direction.

when, 0 < c < 1, the function stretches it.

the function is g ( x ) = (9x )2.

the heighest power of x in g ( x ) = (9x )2 is 2, so the parent function is square function.

the equation of parent function is f ( x ) = x 2 .

the function is g ( x ) = (9x )2 and the parent function is f ( x ) = x 2 .

so, the functions f and g have the following relationship.

g ( x ) = f ( 9x ).

compare the function g ( x ) = f ( 9x ) with g (x ) = f (cx ).

c = 9 ( > 1 ).

so, the function g (x ) = (9x )2 compresses it in the x - direction.
