V=(22-2t)(15-2t)(12-2t) and we are told the thickness is 1/2 so
V=(21)14(11)=3234in^3
B :)
Answer:
64 yds
Step-by-step explanation:
by proportion, MN is half way to BC, so BC = 2(MN) = 64 yds
Answer:
Step-by-step explanation:
Amplitude is twice the coefficent of the sine function. In this case, 
Period is 
divided by the coefficent of x, in this case, 
Phase shift, is how much you sum or subctract from x inside the sine, in this case 
.
Midline you get by hiding the sine and reading what's left, in this case, -4.
2(2x-1) + 2(3x)=4x-2+6x = 10x - 2 & not <span>=10x-1</span>
Answer:
26
Step-by-step explanation:
When you flip two coins, you can have 4 different outcomes:
HH
HT
TH
TT
All outcomes are equally likely, but notice that if you do not keep track of which coin is which, you will get 1/4 of the flips to be both heads, 1/4 of the flips to be both tails, and 1/2 of the flips to be one heads and one tails.
p(both heads) = 1/4
With 105 flips, the expected number of both heads is
105 * 1/4 = 26.25
