Answer:
1
Step-by-step explanation:
Add 4+1=5 then do 5÷5=1
Let her standard pay rate = x
She worked 40 hours for x per hour she also worked 5 hours at 1.5x ( time and a half)
Write an equation:
40x + 5(1.5x) = 1163.75
Simplify:
40x + 7.5x = 1163.75
Combine like terms:
47.5x = 1163.75
Divide both sides by 47.5
X = 24.50
Her regular hourly rate is $24.50
Answer:
using section formula, B(-3, -3)
Answer:
See below.
Step-by-step explanation:
In polar coordinate system, we have two parameters describing a point. The first one is its distance from the origin and second its angle with respect to the positive X axis.
The point ( 3 , pi ) will have a distance of 3 units from the origin. The angle made is pi radians or 180 degrees. The negative Y axis is at 180 degrees from the positive X axis.
Hence the point at a distance of 3 units on the negative Y axis is ( -3 , 0 )
Answer:
34.13%
Step-by-step explanation:
Given the mean score is 450 and the standard deviation is 120.
-The probability of scoring between 450 and 570 can be calculated as below:
Hence, 34.13% of the scores lies between 450 and 570
