Answer:
48x - 40y +24
Step-by-step explanation:
Hello!
The mean is the average of the numbers
To find the average you add them all up and divide the sum by the amount of numbers added
87 + 72 + 99 + 93 + 84 = 435
Divide the sum by the amount of numbers added
435 / 5 = 87
The answer is 87
Hope this helps!
Number one : x^6 yz^8
number two : 64x^6 z^12 / y^9
number three : x^9 y^3
number four : y^7/x^7z^3
number five : x^3/5y^2
number six : x^12y^3/z^6
Answer:
C
Step-by-step explanation:
When to use regression test?
- This is done to find the relationship between 2 variables. One dependent and one independent.
When to use Multiple regression test?
- Extension of regression test. It is used to predict value of 1 variable when it depends on 2-3 other variables. Multivariable, basically.
When to use 1-sided t-test?
- We check for possibility of relationship of something from one side. 1 side effect. With a hypothesis and its alternate.
When to use 2-sided t-test?
- This is same as 1-tailed but it looks for possibility from 2sides. A hypothesis and alternate, whether less or more.
Now, Options A and B are not right since we aren't comparing 2 variables here. People believe second born subjects are more intelligent. We have to perform a test to see whether this is true or not. One sided answer. So, we will use One-sided t-test.
1x+ 3y = -12x + 2y = 6
+12x +12x
13x + 3y = 2y = 6
+3y +3y
13x = 5y = 6
13x = 5y and 5y = 6
