Answer:
Number of apartment = 9
Step-by-step explanation:
Given the ANOVA result :
ANOVA ____ df ____ SS
Regression __ 1 ___ 41587.1
Residual ____ 7 ___
Total _______ 8 __ 51984.5
Number of apartment building in sample (n) :
Degree of freedom (df) = n - 1
The degree of freedom = total = 8
Hence,
8 = n - 1
8 + 1 = n - 1 + 1
9 = n
Hence, number of apartment building in sample = 9
ok.
200-14d<80
-14d<80-200
-14d<-120
d<-120/-14
if you divide the other side with a negative the sign has to change.
d>-120/-14
d>120/14 (both signs are negative making it positive)
d>60/7 (making it into its simplest form by dividing both by 2 as its is the only possibility)
or d>8.57142857143
Answer:
8y-2
Step-by-step explanation:
i would say simple random because Systematic is choosing every 10th or every 15th; every nth number.
Answer & Step-by-step explanation:
In order to solve for <em>x</em>, we can use the Pythagorean Theorem.
Instead of using the original formula, we will rearrange the formula so we can find the missing side, <em>b</em>, which will represent <em>x</em>.
Now, lets plug in our numbers.
So, x equals 92.87
Now, lets find y. Since we did the Pythagorean Theorem, this shows that the triangle is a right triangle. So, that means we already know the measurements of two angles which will help us find y.
180 - (35 + 90)
180 - 125
55
So, y equals 55
