Answer:
D.
Step-by-step explanation:
The problem is asking to multiply x-5 by x^2, so we can set it up to distribute the x^2 to both values. The final answer would therefore be x^2(x-5), which is D.
Answer:
99inches
Step-by-step explanation:
The ratio of the sides of a triangle =2:4:9.
perimeter = 165 inches,
Total ratio= 2+4+9=15
perimeter = 165
Divide the perimeter by total ratio
165/15=11
Each of the sides
= (2×11) =22
(4×11) =44
(9×11)=99
the length of the longest side= 99inches
Answer:
Step-by-step explanation:
Note: If you have any queries related the answer please do comment. I would be very happy to resolve all your queries.
Firstly we will make PMF
For X=0, P=(4/5)^3=64/125
For X=1, P=C(3,1)*(1/5)*(4/5)^2=3*16/125=48/125
For X=2, P=C(3,2)*(1/5)^2*(4/5)=3*4/125=12/125
For X=3, P=C(3,3)*(1/5)^3=1/125
So,
E[X^2]=1*48/125+2^2*(12/125)+3^2/125=0.84
E[X]=48/125+12/125*2+1/125*3=0.6
So,
E[X]^2=0.36
Answer:
The answer should be A.) 25 CM
Step-by-step explanation:
A kililometer is 5000 meters, so all you really have to do is <u><em>divide 5000 meters by 200 meters</em></u> and that gets you 25, which is 25 CM. So the answer is A.) 25 CM
