Answer:
1.5
Step-by-step explanation:
k= y/x
y= 12-4.5 = 7.5
x= 8-3 = 5
k = 7.5/5 = 1.5
Filling in y=1+i without the missing term yields -3-4i.
-3-4i = -3(1+i) - i
So we have to add 3(1+i) to get to -i.
3(1+i) = 3y, so 3y is the answer.
Answer:
The range of values likely to contain the true value of the population parameter is between 44% and 52%.
Step-by-step explanation:
Confidence interval concepts:
A confidence interval has two bounds, a lower bound and an upper bound.
These bounds are dependent of the sample mean and of the margin of error.
The lower bound is the sample mean subtracted by the margin of error, while the upper bound is the margin of error added to the sample mean.
The confidence interval is likely to contain the true value of the population parameter.
In this question:
Sample mean: 48%
Margin of error: 4%
48 - 4 = 44%
48 + 4 = 52%
The range of values likely to contain the true value of the population parameter is between 44% and 52%.
Answer:
Eddy
Step-by-step explanation:
2/12 = .166666666
3/15 =.2
.2 is faster
Use the formula V=Bh
V is 306.52
B is 19.4
to get (h) height you divide
306.52 divided by 19.4= 15.8
