Answer:
Explained below.
Step-by-step explanation:
Consider the variables height and weight.
It is usually seen that taller people are heavier than shorter people.
So a regression analysis can be used to specify this belief.
The statistical questions that are being asked here are:
- What the independent and dependent variables?
- Are there any other factor influencing the dependent variable other than the independent variable?
The variable <em>Y</em> is considered as the dependent variable and the variable <em>Y</em> is considered as the independent variable. And the main purpose of the regression analysis is to predict the value of <em>Y</em> when the value of <em>X</em> is given.
The linear regression model can be used to predict the past and future value of the dependent variables provided that the independent variables for those times are provided.
Answer:
39
Step-by-step explanation:
Given the function :
h(t) = t² + 2
From t = 5 to t = 8
when, t = 5
h(5) = 5² + 2
h(5) = 25 + 2
h(t) at t = 5 ; equals 27
when, t = 8
h(5) = 8² + 2
h(5) = 64 + 2
h(t) at t = 8 ; equals 66
Net Change :
h(8). - h(5)
66 - 27 = 39
Answer:
4
Step-by-step explanation:
First, solve in the brackets,
-3+(-1)
-3-1
-4
Since it is absolute value, take the minus sign away,
therefore the answer is 4
Answer:
1. (7+3)/2
2. 6, 3
3. 5/6
4. 500, 4000
Step-by-step explanation:
1. We are adding 7 and 3 so use the plus sign, THEN we divide by 2
Because we are adding first, put parentheses
(7+3)/2
2. Nearest whole means whole number (so basically no decimal)
5.823 --> 6 (because 8 is closer to 10 than 0)
3.147 --> 3 (because 1 is closer to 0)
3. 1/3+1/2
Find a common difference, which is 6
Multiply to get 6
1/3*2= 2/6
1/2*3=3/6
3+2=5/6 (when adding keep denominator the same)
4. There are 100 centimeters in a meter
5*100= 500 centimeters
There are 1000 grams in a kilogram
4*1000= 4000 grams
Hope this helps, lemme know if somethings still unclear!!
