The answer would give you -9.
You would ALWAYS do multiplication and division first
So first 8 x 2.
Then...you got it!
Hope I helped.
Hey There!
Here is your answer:
<u>The answer is "5 spaces away from each other".</u>
Reason:
Because of these equations:
<u>3+5=8</u>
<u>&</u>
<u>8-5=3</u>
<u>Is proves that that the distance away from each other is 5 spaces.</u>
The answer is 5 spaces.
If you need anymore help feel free to ask me!
Hope this helps!

Answer:
Kindly check explanation
Step-by-step explanation:
To construct confidence interval for difference in proportion ; the following conditions must be met :
1.) The selected samples must have been randomly chosen or selected from a larger population. This is essential in other to eliminate bias.
Each group of samples must be independently chosen. That is, the samples of bug customers chosen must be independent of the sample of small customers selected.
The population from which the samples are drawn must be considerably larger than the sample size. Sample size, n should be ≤ 10% of the population size.
p1 = 160 / 200 = 0.8 ; (1 - p1) = 0.2
p2 = 120 / 300 = 0.4 ; (1 - p2) = 0.6
(p1 - p2) ± Zcritical * sqrt[(p1(1 - p1) /n1) + (p2(1 - p2) / n2)]
This is for the first one :) sorry I don’t have time to do the other two, but this will help with the other ones
Answer:
y=-9/2, x=7
Step-by-step explanation:
You can solve this via substitution. First solve for x in terms of y in one of the equations given. Lets use the first one:
25+4y=x
Now plug 25+4y in for x in the second equation
3(25+4y)-2y=30
75+12y-2y=30
75+10y=30
10y=-45
y=-9/2
Plug this into the first equation:
25-x=-4(-9/2)
25-x=18
x=7
