A prism with a base area of 5 ft² and a height of 10 ft is dilated by a factor of 6/5 .
1 answer:
First we need to find the volume of the prism without the dilated factor:
The volume would be:
Volume of the prism(without dilated) = (area of the base) * (height)
Since,
Area of base = 5
Height of the prism = 10f
Volume(without dilated) = 5*10 = 50
Now let us apply the dilated factor! For that you need to multiply for factor with the volume of the prism without dilation.
Volume of the dilated prism =
* (Volume of the prism without dilation)
Where d = dilated factor. Therefore,
v = 86.4
So the correct answer: 86.4

Answer:
At 5% significance level, it is statistically evident that there is nodifference in the proportion of college students who consider themselves overweight between the two poll
Step-by-step explanation:
Given that a poll was taken this year asking college students if they considered themselves overweight. A similar poll was taken 5 years ago.
Let five years ago be group I X and as of now be group II Y
(Two tailed test at 5% level of significance)
Group I Group II combined p
n 270 300 570
favor 120 140 260
p 0.4444 0.4667 0.4561
Std error for differene =
p difference = -0.0223
Z statistic = p diff/std error = -1.066
p value =0.2864
Since p value >0.05, we accept null hypothesis.
At 5% significance level, it is statistically evident that there is nodifference in the proportion of college students who consider themselves overweight between the two poll
