Also, this is 5 points.
Let's say the numbers are "a" and "b"
hmm say "a" is the smaller, and "b" the greater
so "b" is "4 more than 5 times" "a"
so... 5 times "a" is 5*a or 5a
4 more than "that", will be "that" + 4
or
5a + 4
so.. whatever "a" is, "b" is 5a+4
now, their sum is 22, as opposed to "zz" hehe
so

solve for "a", to see what the smaller one is
what's "b"? well, b = 5a + 4
Answer:
![\sqrt[5]{13^3} = 13^{\frac{3}{5}}](https://tex.z-dn.net/?f=%5Csqrt%5B5%5D%7B13%5E3%7D%20%3D%2013%5E%7B%5Cfrac%7B3%7D%7B5%7D%7D)
Step-by-step explanation:
"nearest pound" means we need to round the number to become a whole number of pounds (either up or down).
14.65 pounds is the cost of bag B.
you would have to subtract 0.65 pounds to get 14 pounds.
Alternatively, you could add 0.35 pounds to get to 15 pounds.
Of these, 0.35 is smaller meaning 14.65 is nearest to 15.
Let me know if this needs further explaining :)
Answer:
We can conclude the mean cost is larger for adopting children from Russia.
Step-by-step explanation:
To answer this question we can perform an hypothesis testing on the differences of the means with the following null and alternative hypothesis:

The significance level we assume is 0.05.
First we calculate the mean standard error:

The harmonic mean of the sample sizes is:

Then we can calculate the estimated standard deviation as:

The t-statistic can be calculated as:

The degrees of freedom are
.
We can look up the P-value in a table or applet. For t=-4.015 and df=32, the P-value is 0.00017.
The P-value is smaller than the significance level, so the effect is significant and the null hyphotesis (China cost is equal or less than in Russia) is rejected.
We can conclude the mean cost is larger for adopting children from Russia.
