150 is the perimeter of the pool
Answer:
a. -1.35
b. 0.177016
Step-by-step explanation:
According to the question, following data is given
Brown eyes american percentage is 45
Random sample be 80 out of which 30 had brown eyes
Based on the above information
The computation is shown below:
a. The proportion of the sample is
The z value is
= -1.35
b Now the P value is
As z comes -1.35
So, there is a two tailed p value i.e. 0.177016
Pretty sure the mean is 5
Let's use the variable 'n' to represent the cost of a notebook and 'p' the cost of a pen.
If Kennel wants an equal number of notebooks and pens, we can create a group of one notebook and one pen, and the resulting cost will be 'n + p'
Then, to find the number of these groups Kennel can buy, we just need to divide the amount of money ($40) by the cost of the group of one notebook and one pen:
If the result is not a whole number, we need to round it down, since we can't spend more money than the budget of $40.
Answer:
10
Step-by-step explanation:
Find the mean
9+12+10+15+15+15+10+x/8=12
divide 86+x/8=12
multiply both sides by 8
86+x=96
sub 86 from both sides
x=10
hope this helps
