distribution has a mean if 18 standard deviation of 4 a value of 24 is how many standard deviations away from the mean

liraira [26]

A value of 24 is 2.5 standard deviations away from the mean

<h3>'How to determine the number of standard deviations away from the mean?</h3>

The given parameters about the distribution are:

Mean = 18

Standard deviation = 4

Value = 24

Let the number of standard deviations away from the mean be x.

The value of x is calculated using

Mean + Standard deviation * x = Value

Substitute the known values in the above equation

18 + 4 * x = 24

Subtract 18 from both sides of the equation

4 * x = 6

Divide both sides of the equation by 4

x = 1.5

Hence, a value of 24 is 2.5 standard deviations away from the mean

So, the complete parameters about the distribution are:

Mean = 18

Standard deviation = 4

Value = 24

24 is 2.5 standard deviations away from the mean

A flower vendor sells roses for 50 cents each. how much does she pay per flower if she makes $6.00 on every $20 worth sold

kkurt [141]

We are given

selling price of one flower is $0.50

so, $SP=0.50$

Let's assume

she sold 'n' flowers to get $20

so, total amount she get after selling 'n' flowers is

$=0.50*n$

$=0.50n$

This is supposed to be $20

so, we can set it equal to 20

$20=0.50n$

now, we can solve for n

we get

$n=40$

we are given

she makes $6.00 on every $20 worth sold

so, we can find cost of 40 flowers is 20-6

total cost is 14

or cost of 40 flowers is $14

now, we can find cost of one flower

$CP=\frac{14}{40}$

$CP=0.35$

so, cost of each flower is 35 cents...............Answer
