Answer = 2.00
Z score is a statistical that corresponds to the standardization of the regular score to a normal distribution
The formula for Z score is Z = [X - mean ]./ (standard deviation)
Here X = 930.00; mean = 900.00; and standard deviation = 15.00
Then, Z = [930.00 - 900.00] / 15.00 = 30.00 / 15.00 = 2.00
Therefore, your answer is 2.00

Answer:
Step-by-step explanation:
5x=y+6 --------- equ 1
2x-3y=4 -------- equ 2
5x - 6 = y
y = 5x - 6
substitute in equ 2
2x-3(5x - 6) =4
2x - 3*5x + 3*6 = 4
2x - 15x + 18 = 4
- 13x = 4 - 18
-13x = -14
x = -14/-13
x = 14/13
substitute in equ 1
5*14/13 = y+6
70/13 - 6 = y
y = ( 70 - 78)/13
y = -8/13

Answer: x < 38
Step-by-step explanation: Raymond has less money than Martin but you don’t know how much. So you use the less than sign to show that it’s less than 38 dollars
Answer:
78.55m^2
Step-by-step explanation:
General formula for the area of a circle is πr^2
π=3.12
r=5m
So let's apply the formula
3.142×(5)^2
3.142×25
78.55
So the area is 78.55m^2
