The scores of an entrance exam for a high school in a particular year were bell-shaped in nature. If the mean and standard deviation were 350 and 50 respectively, then:

P(200 ≤ X ≤ 500) = 0.9973

Step-by-step explanation:

Let assume that the question intends us to find what percentage of students scored between 500 and 200 on this test.

Given that:

We need to first compute the Z test statistics

Thus;

hey there!

if she's saving for six months, let's divide the total number we need for the trip by six, dividing it into the amount that needs to be saved for each month.

500 ÷ 6 =

she needs to save at least this amount each month, so we should use this symbol: ≥

let x be the amount she saves each month.

your final answer is x ≥

hope this !

r(0,90)(x,y) . t(-5,0)

last option

step-by-step explanation:

∆def to ∆d"e"f"

- rotate 90 counterclockwise degrees

- then translated 5 to the left (x --> x - 5)

answer is the last option
