Answer:
she has $19.5
Step-by-step explanation:
156/4=39*3=117 spent on bag
156-117=39 left for scarf so divide 39/2=19.5
19.5 was used for the scarf and only 19.5 was left over
If you would like to solve 2 1/2 divided by 1 5/8, you can calculate this using the following steps:
2 1/2 / 1 5/8 = 5/2 / 13/8 = 5/2 * 8/13 = 20/13 = 1 7/13
The correct result would be C. 1 and 7/13.
The equation for volume of a sphere is:
Volume = 4/3 * PI * r^3
r is the radius = 1 inch
Volume is given as 4 cubic inches per second increase.
Given: dv/dt = 4 cubic inches per second.
Need to find dr/dt
Formula for volume of a sphere is: V = 4/3 * π * r^3
so now we have:
4 in^3 = 4 * π *1^2
Divide both sides by 4 * π *1^2
4 in^3 / 4π = 1/π inch per second.
The answer is 1/π inch per second ( exact answer)
or as a decimal: 0.3183 ( round as needed).
Step-by-step explanation:

Answer: Yes, it would be biased. If David asked the question about movies, however, it would not be.
Step-by-step explanation: It would be biased because he is asking listeners to his show who send fan mail. Fan mail is typically only sent by people who enjoy the creator. Therefor, he would be surveying only people who enjoy his podcast so the results would be heavily biased. I am unsure about how the second part of the question relates to the first part. If David were to ask the same 100 individuals about their favorite movies rather than whether or not they liked his podcast, it would not contain biased results because he or his podcast does not have anything to do with movies. :)
