2/3 is 0.6. 1/2 is 0.5.
so 0.6 is less than 0.75 and it will round up to 0.5, not to 1.
so 4 2/3 will round to 4 1/2.
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:
x = 80°
Step-by-step explanation:
To solve this we just need to know that the sum of the inner sides of a triangle will always give us 180 °
from here we only have to apply a simple formula by adding the sides of the triangle and knowing that the result is 180 and from there clear the value x that we need to find out
70 + 30 + x = 180
x = 180 -30 - 70
x = 80°
Answer:
x = 2
