Answer: 40%
Step-by-step explanation: 1 Divided by 2.5 is 0.4, or 40%.
Answer:
Step-by-step explanation:
Transformed of the function has been given as,
f(x) = 
= 
Parent function of this transformed function = 
Vertical stretch = By a factor of 
Horizontal shift = 3 units to the left
Vertical shift = 3 units up
Now we can summarize these transformations as,
1). Parent function g(x) =
has been vertically stretched by a factor of 
2). Followed by the translations of 3 units left and 3 units up.
31/50
31 ÷ 50 = 0.62
0.62 x 100 = 62%
So the answer is 62%
Hope this helps I didn't know if the 7k was apart of the problem or a typo
The probability that student scored more than 850 we shall proceed as follows:
z=(x-μ)/σ
where:
x=850
μ=750
σ=50
thus
z=(850-750)/50
z=2
thus
P(x>850)=1-P(x<850)=1-P(z<2)=1-0.9772=0.0228
Answer: P(x>850)=0.0228
