17=70h
Divide each side by 70
It would be 14 mins and 33 seconds
2414 total seats.......221 reserved.....x = non-reserved.....y = remaining seats
y = 2414 - (x + 221)
y = 2414 - x - 221
y = 2193 - x <=====
Answer:
6/8 and 12/16
Step-by-step explanation:
This is because 3/4 x 2/2 = 6/8 and 3/4 x 4/4 = 12/16
Answer:
z-value of rachel = 1.875
z-value of rob = -2
z-value of Rachel is more than that of rob. Thus rob is earning below average and rachel is earning above average.
Step-by-step explanation:
Let's denote the salary of Rob and Rachel per year by X. So, X = $50,000
We are told that;
For Rachel's industry;
Mean salary;μ1 = $35,000
Standard deviation;σ1 = $8,000
For Rob's industry;
Mean salary;μ2 = $60,000
Standard deviation;σ2 = $5,000
Formula for z - value is;
z = (X - μ)/σ
Thus;
z-value for rob is;
z2 = (X - μ2)/σ2
z2 = (50000 - 60000)/5000
z2 = -2
z-value for rachel is;
z1 = (X - μ1)/σ1
z1 = (50000 - 35000)/8000
z1 = 1.875
z-value of Rachel is more than that of rob. Thus rob is earning below average and rachel is earning above average.
Usually it's fun when you know what's going on....
