Answer:
<em>A.) There is a 3.4% chance that a random sample of 50 expectant mothers will have a mean age of 26.5 years old or greater if the mean age for a first time mother is 26 years old.</em>
Step-by-step explanation:
The mean age for a first time mother is assumed 26 years old (null hypothesis) and <em>p-value</em> of the sample mean (26.5 years ) is found as 0.034.
This is the probability of having first time mother mean age 26.5 or greater <em>under the assumption of null hypothesis. </em>
Can you reformat the question?
I think the value of y would be 9
because if you put 3 in place of x the equation would be
6.4(3)+2.8y then you would simplify it to 19.2+2.8y
19.2-44.4=25.5
25.2/2.8=9 which is the value of y
answer=9
Answer:

Step-by-step explanation:
(Assuming the den is a rectangle)
Let
be the length of the den. Because the length is 10 feet longer than the width, the width of the den can be represented as
.
The area of a rectangle is given as
, therefore we can form the following equation:

Expanding this, we have:

This factors into
, therefore
.
Because -11 is extraneous, the length of the den is
feet and the width is
. Thus, the dimensions of the den are
.
300 total / 5 cards at a time
=60 times they folded in the ratio
Ms. Johnson folds 2 cards at a time, if she folded 60 times, she folded 120 cards total.
Ms. Siple folds 3 cards at a time, if she folds 60 times, she folded 180 cards total.
