Answer: 7 9/10 gallons of paint
Step-by-step explanation:
Mike needs:
Red paint: 4 4/5 gallons
Brown paint: 3 1/10 gallons
Those are mixed fractions. To facilitate, we need to transform them into Improper fraction (numerator > denominator), so:
4 4/5 = (5*4+4)/5 = 24/5
3 1/10 = (10*3+1) = 31/10
So, Mike needs:
Red paint: 4 4/5 gallons = 24/5
Brown paint: 3 1/10 gallons = 31/10
To find out how much gallons of paint he needs in total, we need to sum the amounts of red and brown paint:
<u>24</u> + <u>31</u> =<u> 48 + 31 </u>= <u>79</u>
5 10 10 10
So, he needs 79/10 gallons of paint. To transform into mixed fraction again:
79/10 = 70/10 + 9/10 = 7 + 9/10
7 9/10 gallons of paint

Answer:
a) 2.0702
b) 2.07
Step-by-step explanation:
Given:
Sample, n = 840
standard deviation, σ = 60
a) The standard deviation of the sampling distribution, will be:
= 2.0702
Standard deviation of the sampling distribution is 2.0702
b) According to the 68 part of the 68-95-99.7 rule, 68% of all values of x fall within 1 standard deviation on either side of the unknown mean μ.
Therefore, missing number will be:
![1 * [\frac{\sigma}{\sqrt{n}}]](https://tex.z-dn.net/?f=%201%20%2A%20%5B%5Cfrac%7B%5Csigma%7D%7B%5Csqrt%7Bn%7D%7D%5D%20)
= 1 * 2.0702
= 2.0702 ≈ 2.07
Answer:
$ 65.59 more per week
Step-by-step explanation:
Assuming she worked <u>52</u> weeks a year as a clerk :
30534 - <u> 52</u> * 521.6 = $ 3410.80 more per year
now each WEEK that is 3410.80 / 52 = 65.59
