Answer:
9
Step-by-step explanation:
60 requests are made.
Spencer gets 25% of these requests. Convert this to a decmal (divide by 100) to get 0.25. 25% of 60 is:

So Spencer gets 15 requests. Now do the same process for Tanvi:

So Tanvi gets 6 requests. To find out how many more requests Spencer gets compared to Tanvi:

Therefore, Spencer gets 9 more requests than Tanvi.
Answer:
d. all of the above
Step-by-step explanation:
A two-way ANOVA generally compares the "mean differences" between different groups that are being split into two distinct independent variables which are also referred to as factors. The main aim of a two-way ANOVA is to comprehend if there is any interaction that exists between these two "independent variables" to that of the "dependent variable".
A simple main effect test is described as a phenomenon in which the effect of one specific 'independent variable' that possess within one level related to a second or the other 'independent variable'. It utilizes the "df" and the "error term" from the 'whole design'.
The post-hoc test is described as a test that generally analyzes the results of experimental data.
Answer: 
Step-by-step explanation:
Given
Curve is 
boundary is y=0 i.e.

The volume of solid generated when rotated about the x-axis is

Putting values we get
![\Rightarrow V=\int_{-1}^{1}\pi (3-3x^2)^2dx\\\\\Rightarrow V=\int_{-1}^{1}\pi(9+9x^4-18x^2)dx\\\\\Rightarrow V=\pi \left [ \frac{9x^5}{5} - 6 x^3 + 9 x\right ]_{-1}^{1}\\\\\Rightarrow V=9.6\pi](https://tex.z-dn.net/?f=%5CRightarrow%20V%3D%5Cint_%7B-1%7D%5E%7B1%7D%5Cpi%20%283-3x%5E2%29%5E2dx%5C%5C%5C%5C%5CRightarrow%20V%3D%5Cint_%7B-1%7D%5E%7B1%7D%5Cpi%289%2B9x%5E4-18x%5E2%29dx%5C%5C%5C%5C%5CRightarrow%20V%3D%5Cpi%20%5Cleft%20%5B%20%20%5Cfrac%7B9x%5E5%7D%7B5%7D%20-%206%20x%5E3%20%2B%209%20x%5Cright%20%5D_%7B-1%7D%5E%7B1%7D%5C%5C%5C%5C%5CRightarrow%20V%3D9.6%5Cpi)
1 quarter= .25
200 × .25= 50
1 dime= .10
.10×15= 15
1 penny= .01
.01× 300= 3
Answer: 50+15+3= $68
