A 1.5 standard deviation above the mean is
np + 1.5 <span>√(np(1-p))
We are given with
np = 200
p = 200/n
The standard deviation is
</span><span>√200(1-200/n))
Substituting
200 + 1.5 </span>√200(1-200/n))
By inspection, if the value of n is 200, then the radical will result to the value of 1. Only by increasing the value of n greater than 200 will the radical result to a value of less than 1 and decreasing the spread of the mean.
The answer is
the minimum is 201
the maximum is infinity
Answer:4/7
Step-by-step explanation:
Can be broken down into square root of 16 over the square root of 49. Square root of 16=4. Square root of 49=7. Final answer=4/7
Gas &; snacks = $387.00
snacks = $35.80
gas ??
Each gallon $2.54
First, how much spent only on gas. Subtract snacks from total.
387 - 35.80 = 351.20
then number of gallons by dividing total spent in gallons by cost per gallon
351.20 ÷ 2.54 = 138.2
rounded to nearest gallon .. 138 gallons of gas
