Answer:
15
Step-by-step explanation:
x/2 + 6 / 3 = 4.5
x/2 + 6 = 4.5 *3
x/2 = 13.5 - 6
x = 7.5 * 2
x = 15

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.
Answer:
The answer to your question is 4
Step-by-step explanation:
Data
calculate x
Process
1.- Calculate the length of RT using trigonometric functions
sin 60 = 2√3 / RT
-Solve for RT
RT = 2√3 / sin 60
-Simplification
RT = 2√3 / √3/2
RT = 4
2.- Calculate RQ using trigonometric functions
tan 45 = RQ / RT
-Solve for RQ
RQ = RT tan 45
-Substitution
RQ = 4 (1)
-Result
RQ = x = 4
