Using formula v of hemisphere= 2/3x22/7xr3
v of hemi a= r3= 12.8
                 = r   =2.3
v of hemi b= r3 = 59.6
                 =r    = 3.9
So the ratio is 2.3:3.9

The volume is scale factor³
Take the square root of the volume ratio

\sqrt{ \frac{27}{125} } which is 
\frac{ \sqrt{27} }{ \sqrt{125} }

\frac{3}{5}

The ratio of their radii is 3 : 5

Write an equation for the translation of y = |x|. 13 units down
olga55 [171]
The idea for transitions for an equation like this is
y = m|x - h| + k
where m = slope
h = how much left or right (note the negative)
k = how much up or down

moving 13 down would mean
k = -13

so
y = |x| - 13
D. would be your answer

Answer:

The margin of error that corresponds to a 95% confidence interval is 4.96.

Step-by-step explanation:

We have the standard error(which is the same as the standard deviation of the sample), so we use the students t-distribution to solve this question.

The first step to solve this problem is finding how many degrees of freedom, we have. This is the sample size subtracted by 1. There are 6 days, so

df = 6 - 1 = 5

95% confidence interval

Now, we have to find a value of T, which is found looking at the t table, with 35 degrees of freedom(y-axis) and a confidence level of 1 - \frac{1 - 0.95}{2} = 0.975([tex]t_{0.975}). So we have T = 2.5706

The margin of error is:

M = T*s = 2.5706*1.93 = 4.96

The margin of error that corresponds to a 95% confidence interval is 4.96.
