Answer:
Our answer would be x > 3
I have attached a picture of the graph below.
Get x to one side
So minus 90 from each side
-90÷-3=30
Answer: x=30
Answer:
Test statistic = 1.664
Step-by-step explanation:
The hypothesis :
H0 : μ = 47.2
H1 : μ ≠ 47.2
Given that :
Sample mean, xbar = 47
Sample size, n = 250
Standard deviation, σ = 1.9
The test statistic :
(xbar - μ) ÷ (σ/√(n))
T = (47 - 47.2) ÷ (1.9/√(250))
T = (0.2 / 0.1201665)
Test statistic = 1.664
Answer:
x=15/4 or x=3.75
Step-by-step explanation:
4/5*x=3
4/5=0.8
0.8*3.75=3
Let x be the total weekly sales.
His salary is $300/week + 1.8% (x), if he wants to earn $570, then:
300 + 1.8%(x) = 570
1.8%(x) = 270
0.018 (x) = 270
and x = 270/0.018 = $15,000
