we know that
normal distributions:
a function that represents the distribution of many random variables as a symmetrical bell-shaped graph
It is a very common continuous probability distribution
we know that
heights of students in any class is continuous
because it can be any real numbers
so, option-A..........Answer
The interest rate would be 20%.
The formula is derived from the compound interest formula

.
We want to isolate r in this equation to rewrite the formula. The first thing we would cancel, outside parentheses, would be p; divide both sides by p and we have

We want to cancel the exponent, t, next. We can raise a power to its reciprocal to undo it; for example, raising a squared amount to the 1/2 power will undo the exponent. We will raise both sides of this to the 1/t power:

Now we cancel the 1 by subtracting, giving us

Using this formula, we plug in 3600 for A, 2500 for p and 2 for t:
Answer:
I THINK IT IS 15.24 SORRY IF ITS WRONG I TRYED TO WORK IT OUT
Step-by-step explanation:
Answer:
$14.64
Step-by-step explanation:
First, find how much he spent on the calculators
Divide the amount spent on calculators by the number of students
calculator cost/students
117.76/16=7.36
So, he spent 7.36 on each student so far.
To find how much he still has left to spend, subtract the amount he has spent from the total he can spend
total-$ spent on calculators
22-7.36=14.64
He can still spend $14.64 on each student
Hope this helps! :)
Answer:42.25%
Step-by-step explanation:25+25+25+25=100 so divide 4 into 40 it equals 5 and 5-40=35 so 35.00+7.25=42.25
