Answer:
58p+15
Step-by-step explanation:
First, we want to get rid of the parentheses in the equation. To do that, let's start with 7(1+10p). We multiply 7 by each item in the parenthesis, and get 7+70p. Keep that little thing in mind, we will use it later. Next, same process with the other part, and we get 8+48p. We multiplied both parts out, so now we just add like terms. 7 and 8 don't have letters, so we add them to get 15. 10p and 48p do have letters, so we add those together and get 58p. We can't add that to the other numbers, because 58p is 58 times p, and 15 doesn't have that p so it wouldn't work without knowing p. What we are left with, by simplifying the problem, is 58p+15, or 15+58p. The order doesn't matter, as long as you have that answer.
Answer:
A sample of 499 is needed.
Step-by-step explanation:
In a sample with a number n of people surveyed with a probability of a success of 
, and a confidence level of 
, we have the following confidence interval of proportions.
In which
z is the zscore that has a pvalue of 
.
The margin of error is given by:
In this question, we have that:
90% confidence level
So 
, z is the value of Z that has a pvalue of 
, so 
.
How large a sample would be required in order to estimate the fraction of tenth graders reading at or below the eighth grade level at the 90% confidence level with an error of at most 0.03
We need a sample of n, which is found when 
. So
Rounding up
A sample of 499 is needed.

Please check the explanation.
Step-by-step explanation:
Ascending Order:
When we talk about the numbers to be arranged in ascending order, it means the numbers need to be arranged from smallest to largest.
For example, if we have to arrange the numbers from 1 to 5 in ascending order.
It means, the ascending order will be: 1, 2, 3, 4, 5
Now, let us arrange the given numbers in ascending order.
a) 2234 to 2238 2234 2235 2236 2237 2238
b) 4099 to 4103 4099 4100 4101 4102 4103
c) 3298 to 3302 3298 3299 3300 3301 3302
d) 7269 to 7273 7269 7270 7271 7272 7273
e) 6354 to 6358 6354 6355 6356 6357 6358
f) 8379 to 8383 8379 8380 8381 8382 8383
g) 7365 to 7369 7365 7366 7367 7368 7369
Answer:
3.5 in.
Step-by-step explanation:
17.5 ÷ 5 = 3.5
You are adding 40 every time.
The 100th term is 7+(99*40)=3967
