Jerry took a sample of 4 employees in his office and observed how many hours they each worked one day.

Illusion [34]

The error in Jerry's calculation is 4.84

The number of employees, N = 4

The mean is calculated as:

$\mu = \frac{10+2+4+8}{4} \\\mu = \frac{24}{4} \\\mu = 6$

The formula for the standard deviation is:

$SD =\sqrt{\frac{\sum{(x-\mu)^2}}{N} }$

This can be further calculated as:

$SD = \sqrt{\frac{(10-6)^2+(2-6)^2+(4-6)^2+(8-6)^2}{4} }\\\\SD = \sqrt{\frac{4^2+(-4)^2+(-2)^2+(2)^2}{4} } \\\\SD = \sqrt{\frac{16+16+4+4}{4} } \\\\SD = \sqrt{\frac{40}{4} } \\\\SD = \sqrt{10} \\\\SD = 3.16$

Jerry thinks the Standard Deviation = 8

The true Standard Deviation = 3.16

Error = |True value - Measured value|

Error = |3.16 - 8|

Error = 4.84

Riley drink 4/5 quart of iced tea and her friend drink 0 3/10 quart how much more of a quart of iced tea did Riley drink than he

Arada [10]

Answer:

$\frac{1}{2}$ quart

Step-by-step explanation:

Given:

Riley drink 4/5 quart of iced tea

And her friend drink 0 3/10 quart of iced tea

Question asked:

how much more of a quart of iced tea did Riley drink than her friend = ?

Solution:

Riley drank of iced tea = $\frac{4}{5}$

Her friend drank of iced tea = $0\frac{3}{10}$

= $\frac{3}{10}$

We will subtract the share of her friend from Riley's share

Riley drank more than her friend = $\frac{4}{5} - \frac{3}{10}$

= $\frac{5}{10}$

= $\frac{1}{2}$

Thus, Riley drank $\frac{1}{2}$ quart more than her friend.

Your class earned $110.00 Saturday afternoon by washing cars to raise money for a class trip. This is 14 of the money needed for

Galina-37 [17]

Answer: $1,540.00 is the total amount needed for the class trip

Step-by-step explanation:

Data: $110.00 earned for class trip

14th of the money needed

Money needed: x

<u>Step one, Make the equation</u>

110x14=x

Reason: Since we know 110.00 is a 14th of the money needed, we know multipling it by 14 will get us the money needed for the class trip. Having it in an equation will make it easier to solve.

<u>Step two, Evaluate the equation</u>

110x14=x=1540=x

Reason: The only thing that was left to do was to multiply 110 by 14 to get 1540 since the x was already isolated to begin with. That leaves us with the answer of x=1540.

However, since this is a real world problem, we have to make the answer more realistic so the final answer is '$1,540.00 is the total amount needed for the class trip'

I hope this helps!
