Answer:
60 oz of water to add
45 oz of 35% salt solution should be used
Step-by-step explanation:
Let x = amt no. ounces in the first solution
and 105 - x = amt no. of ounces in the second solution
Ist solution contains 0% salt
2nd solution contains .35(105 - x) salt
.15(105= amt of salt in mix
So.
amt of salt in 1st solution + amt of salt in 2nd solution = amt of salt in the mix
0 + .35(105 - x) = .15(105)
Let's get rid of the fractions by multipying thru the equation by 100
35(105 - x) = 15(105)
3675 - 35x = 1575
-35x = -2100
x = 60 oz of water to add
105 - 60 = 45 oz of 35% salt solution should be used

Answer:
7 miles
Step-by-step explanation:
As, we will take unit rate as "x"
So, for one day = x distance
For 5 days = 5(x)
For 5 days she covered 35 miles
So therefore,
5(x) = 35 miles
X= 35/5
X=7 miles
For a day= 7 miles are covered

Answer:As the sample size increases, the impact of the misrecorded data on the mean decreases.
Step-by-step explanation:
The size of an experiment is very important in a research. Large experimental size with many sample unit helps to minimize error this is because the error is shared among all the samples but when an experimental unit is small the error is usually high.
As sample sizes increases the number of misrecorded data on the mean decreases this is because error is usually spread across all samples in a large sample size and the mean is the average performance of the samples.
