Answer:
5 5/8
Step-by-step explanation:
9 = 9/1
so 9 x 5/8 = 9/1 x 5/8
you could quickly make it 45/8 or make it 9x5/1x8
45/8 is improper so you have to see which multiple of 8 is the highest without exceeding the numerator
40 is the closest and it is 8x5 so 5 will be the integer.
there are 5 leftover so 5 is also the numerator
and the denominator stays 8 as there is no further simplifying
so, the answer is 5 5/8
Answer:
Your answer would be 288
Step-by-step explanation:
You start off with the equation ( V= Bh )
Where "B" represents the area of the base ( which case you multiply 8 and 12 and thus getting 96 as your answer for finding "B")
and Lastly you multiply your "B" with the "h" ( which represents the height) and therefore you multiply 96 and 3
which equals to 288

$7.92 is a reasonable amount for each of them to pay.
Answer:
a)= 2
b) 6.324
c) P= 0.1217
Step-by-step explanation:
a) The mean of the sampling distribution of X`1- X`2 denoted by ux`-x` = u1-u2 is equal to the difference between population means i.e = 2 ( given in the question)
b) The standard deviation of the sampling distribution of X`1- X`2 ( standard error of X`1- X`2) denoted by σ_X`1- X`2 is given by
σ_X`1- X`2 = √σ²/n1 +σ²/n2
Var ( X`1- X`2) = Var X`1 + Var X`2 = σ²/n1 +σ²/n2
so
σ_X`1- X`2 =√20 +20 = 6.324
if the populations are normal the sampling distribution X`1- X`2 , regardless of sample sizes , will be normal with mean u1-u2 and variance σ²/n1 +σ²/n2.
Where as Z is normally distributed with mean zero and unit variance.
If we take X`1- X`2= 0 and u1-u2= 2 and standard deviation of the sampling distribution = 6.324 then
Z= 0-2/ 6.342= -0.31625
P(-0.31625<z<0)= 0.1217
The probability would be 0.1217
Answer:
49-63
Step-by-step explanation:
1. (7·7) - (7·9)
2. (49) - (63)
3. 49 - 63 = -14
Hoped I helped!! :)
