Answer:
8
Step-by-step explanation:
The formula of volume is 4/3 × π × radius3.
volume of smaller sphere = 4/3 x 3.14 x 3*3*3
v = 113.04
volume of larger sphere = 4/3 x 3.14 x 6*6*6
v = 904.32
904.32 / 113.04 = 8
Answer:
y = 2/3x + 1 1/3
Step-by-step explanation:
As y increases by 2, x increases by 3, so 2/3. The y - intercept is 1 and 1/3 so plus 1 1/3
Answer:
And the width for the confidence interval is given by:
And we want to see the effect if we increase the confidence level for a interval. On this case if we increase the confidence level then the critical value for the confidence interval would be higher and then the width of the interval would increase. So then the best answer for this case would be:
B. Increasing the level of confidence widens the interval.
Step-by-step explanation:
Let's assume that we have a parameter of interest who represent for example the true mean for a population. And we can construct a confidence interval in order to estimate this parameter if we know the distribution for the statistic let's say and for this particular example the confidence interval is given by:
Where ME represent the margin of error for the estimation and this margin of error is given by:
And the width for the confidence interval is given by:
And we want to see the effect if we increase the confidence level for a interval. On this case if we increase the confidence level then the critical value for the confidence interval would be higher and then the width of the interval would increase. So then the best answer for this case would be:
B. Increasing the level of confidence widens the interval.
Answer: 1/8 of the carton of orange juice and 1/16 of the carton of apple juice.
Step-by-step explanation:
If the fraction of the carton of orange juice that was shared by the four friends Is ½
Then, by assuming each friend had equal portion, the fraction of carton received by each friend =½ ÷ 4
= ⅛
Each friend had 1/8 of the orange juice
In the same vein, if the fracfion of the carton of apple juice shared by the 4 friends = ¼
Then the fraction that got to each friend = ¼÷4 = 1/16
