Answer:
7
Step-by-step explanation:
σ = 4 ; μ =?
8.52 to the left of X
.
P(X < 8.52) = 64.8%
P(X < 8.52) = 0.648
Using the Z relation :
(x - μ) / σ
P(Z < (8.52 - μ) / 4)) = 0.648
The Z value of 0.648 of the lower tail is equal to 0.38 (Z probability calculator)
Z = 8.52 - μ / 4
0.38 = 8.52 - μ / 4
0.38 * 4 = 8.52 - μ
1.52 = 8.52 - μ
μ = 8.52 - 1.52
μ = 7
Answer:
Step-by-step explanation:
= 648 the length(12m), width(6m), and height(9m) that all i can give you for now because this got me losing brain sells
What do you mean this question dosent make any sence
8 x 1 = 8
8 x 1/2 = 4
8+4 =12
therefore, 8 x 1 1/2 = 12
Answer:
6x^7.
Step-by-step explanation:
The exponent property for this would be that
x^a * x^b = x^a + b.
So x^2 * x^5 = x^2 + 5 or x^7.
The other part is just multiplying the coefficients 3 and 2, which is 6.
Put these together and you get your answer 6x^7.
