Answer:
13cm
Step-by-step explanation:
substitute values we have into the formula:
1664 = 16 x w x 8
rearrange:
1664/16×8 = w
which equals 13
Should be... x ÷ -1.5 = 21
Since the length is 10 in. You must multiply it by
and then multiply by
. The reason for this is because if you divide ten by 5 it will be 2, then if you divide 2 by 2 it will be 1.
Answer:
C. n=23; p^=0.5
Step-by-step explanation:
Normal distribution is symmetrical about the mean.
So, p should be close to ½
Answer:
The answer is letter B, The water level in a bathtub as it drains over time.
Step-by-step explanation:
It is best to learn the meaning of <u>"negative correlation"</u> first.
Correlation- In Mathematics, "correlation" means a measure of the relationship between two variables.
<em>Positive Correlation- </em>when the values of the variables increase together.
<em>Negative Correlation- </em>when one value of a variable increases while the other variable's value decreases.
*The situation above is asking for a negative correlation, therefore the answer is letter B (The water level in a bathtub as it drains over time).
The variables are: <u>water level and draining time</u>
As the draining time increases, the water level in the bathtub decreases. This is clearly an example of a negative correlation.
