Answer:
C
Step-by-step explanation:
It is between three and four.
Question author, it's spelled pi not pie, and we use just use the Greek letter π. Students, demand better from your teachers.
1. Rectangular prism, aka a box. Volume is length times width times height.
V = 5×7×9 = 315 cubic feet
That's cubic feet of course, the product of three lengths. We didn't even need to do the problem, just look for the common answer and pick the one with the right units. I just saw that same pattern in a volume problem yesterday.
Answer: 315 cubic feet, first choice
2. Cylinder, volume is base area times height, πr²h. We have a radius of r=14/2=7 yd and h=8 yd. We're using π=3.14.
V = πr²h = 3.14(7²)(8) = 1230.88 cubic yds
Answer: 1230.9 cubic yards, last choice
Answer: 2 cups
Step-by-step explanation:
(a) No preference is given to any one student?
<span>A simple combination of four selections out of 14: </span>
<span>
14! / (10! 4!) = 14*13*12*11 / (4*3*2*1) </span>
<span>
= 7*13*11 = 1,001 </span>
<span>(b) One particular student must be awarded an assistantship? </span>
<span>That leaves 3 selections out of 13 for the other positions: </span>
<span>
13! / (10! 3!) = 13*12*11 / (3*2*1) </span>
<span>
= 13*2*11 = 286 </span>
<span>(c) The group of applicants includes eight men and six women and it is stipulated that at least one woman must be awarded an assistantship? </span>
<span>We have the original 1,001 possibilities from part (a), minus all of those that awarded all the positions to men: </span>
<span>
1,001 - 8! / (4! 4!) = 1,001 - 8*7*6*5 / (4*3*2*1) </span>
<span>
= 1,001 - 70 = 931

The line should be over the part that repeats
the real anser is 0.54545454
the part that repeats is 54
so it should be 0.54 with a line over it
by doing 0.545 witha line, that means 0.545545545545 which is wrong
