Answer:
n= 2/3 - 5/6k , ker
Step-by-step explanation:
-2n-5k+8-4n-11=-7
-6n-5k+8-11=-7
-6n=-7+3+5k
-6n=-4+5k
then divide both sides by -6 to get your answer
n= 2/3 - 5/6k , ker
The correct answer would be 1.
Answer:
$3780
Step-by-step explanation:
Salary per month = $10500
Expense on food
= 36% of the monthly salary
= 36% of $10500
= (36/100) × $10500
= 36 × $105
= $3780
So, they spend $3780 on food per month.
Answer:
X ~ N(27, 4) ;
xbar ~ N(27, 0.1026) ;
0.5 ;
0.5
Step-by-step explanation:
Probability distribution of X : N(μ, σ²)
μ = 27 ; σ = 2
X ~ N(μ, σ²) = X ~ N(27, 2²) ;X ~ N(27, 4)
Distribution is approximately normal ; μ = xbar ; xbar = 27
(Standard Error)² = (σ/√n)²= (2/√39)² = 0.1026
xbar ~ N(μ, σ²) = xbar ~ N(27, 2²) ; xbar ~ N(27, 0.1026)
Probability that a randomly selected individual found a job in less than 27 weeks :
P(X < 27) :
Obtain the Zscore :
Z = (x - μ) / σ
Z = (27 - 27) / 2 = 0/2
Z = 0
P(Z < 0) = 0.5
D.) n = 36
P(X < 27) :
Obtain the Zscore :
Z = (x - μ) / σ/√n
Z = (27 - 27) / (2/√36) = 0/0.33333
Z = 0
P(Z < 0) = 0.5
The answer is B because 20/4 equals 5 then 5-4 equals 1. So therefore your answer is B)1
