Answer:
v = 9
Step-by-step explanation:
6(v + 3) = 72
6v + 18 = 72
6v = 54
v = 9
Based on the data provided if the customer went to the shop
and bought the potting soil and shrubs with the total bill of $94.75 and the
potting soil alone is for $11.50. We can determine the price of the shrubs in
total by deducting the 2 values. $94.75 - $11.50 = $83.25. Now that we have the
total amount of the shrubs to get the amount of each shrub we then divide the
total amount versus the number of shrubs which is 9, ergo $83.25/9 = 9.25 per
shrub.
So the answer to this question is:
D. 9p + $11.50 = $94.75 p=$9.25
Answer:
X = 5
Step-by-step explanation:
(23x+1) = (27x-19)
23x-27x = -1 -19
-4x = -20
x = 5
Answer:
Step-by-step explanation:
function 1
slope=(1-0)/(0+2)=1/2
or slope=(4-1)/(2-0)=3/2
which is not same.
so it is not linear.
Function 2.
slope=(1+2)/(-3+4)=3/1=3
or slope=(4-1)(-2+3)=3/1=3
or slope=(7-4)/(-1+2)=3/1=3
slope is same. so it is linear.
Answer:
The 95% confidence interval for the true proportion of all teams that had a season winning percentage better than 0.500 is (0.1853, 0.6147).
Step-by-step explanation:
In a sample with a number n of people surveyed with a probability of a success of
, and a confidence interval
, we have the following confidence interval of proportions.

In which
Z is the zscore that has a pvalue of
.
For this problem, we have that:
8 out of the 20 teams in the sample had a season winning percentage better than 0.500. This means that
.
95% confidence interval
So
, z is the value of Z that has a pvalue of
, so
.
The lower limit of this interval is:

The upper limit of this interval is:

The 95% confidence interval for the true proportion of all teams that had a season winning percentage better than 0.500 is (0.1853, 0.6147).
