Answer:
infinite solutions
Step-by-step explanation:
Hey there!
In order to solve this problem, we need to first distribute the 
This is equal to 
Now we can combine like terms
and
cancel out
also
and
cancel out
The equation ends up as 0 = 0
So the answer to this answer is infinite solutions
Answer:
P(2.50 < Xbar < 2.66) = 0.046
Step-by-step explanation:
We are given that Population Mean,
= 2.58 and Standard deviation,
= 0.75
Also, a random sample (n) of 110 households is taken.
Let Xbar = sample mean household size
The z score probability distribution for sample mean is give by;
Z =
~ N(0,1)
So, probability that the sample mean household size is between 2.50 and 2.66 people = P(2.50 < Xbar < 2.66)
P(2.50 < Xbar < 2.66) = P(Xbar < 2.66) - P(Xbar
2.50)
P(Xbar < 2.66) = P(
<
) = P(Z < -1.68) = 1 - P(Z 1.68)
= 1 - 0.95352 = 0.04648
P(Xbar
2.50) = P(
) = P(Z
-3.92) = 1 - P(Z < 3.92)
= 1 - 0.99996 = 0.00004
Therefore, P(2.50 < Xbar < 2.66) = 0.04648 - 0.00004 = 0.046
160 cm^2
2 by 5 by 10
2*10=20
20*2 sides=40 cm^2
2*5=10
10*2 sides=20 cm^2
5*10=50
50*2 sides=100 cm^2
40+20+100=160
4x-1=x+26
3x-1=26
3x=27
x=9
