72 / 3 = 24
Answer:
£ 38,110
Step-by-step explanation:
We need to find salary for 1 year (12 months).
- Monthly Salary = 1410, so yearly would be:
1410 * 12 = 16,920
- 26% of total profit. Let's find the profit first:
Profit is Income - Cost
So, that would be (from table):
Profit = 549000 - 473500 = 75,500
26% of that would be:
26/100 = 0.26
0.26 * 75,500 = 19,630
- 390 bonus for each month she sells atleast 16 cars
Out of 12 months (1 year), she sold at least 16 cars in 4 months, so she gets bonus of 390 for those 4 months, that would make:
390 * 4 = 1560
Total Pay for the year would be summation of all these:
Total Pay = 16,920 + 19,630 + 1560 = £ 38,110

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
