Answer:
A. Regression, independent
Step-by-step explanation:
Regression analysis can be regarded as a statistical methods which is been utilized in estimating the relationships that exist between a dependent variable as well as one or more independent variables. It is tools used in assessment of strength of the relationship that between variables, it could be used to model future relationship between variables.
Regression analysis posses different
variations, These are;
✓ linear
✓ nonlinear
✓multiple linear,
For linear model, this equation can be used.
Y = (a + bX + ϵ)
Where
Y =Dependent variable
a =Intercept
X= Independent variable
ϵ = Residual error
b =Slope
It should be noted that Regression
analysis is the statistical process of estimating the relationship between dependent and independent
variables.
The Romanov family ruled for 300 years.
Answer:
38
Step-by-step explanation:
He will need 38 because,
17 muffins x 6 blueberries = 102 blueberries
he already has 64, so to find the remaining amount he needs
102 blueberries - 64 blueberries = 38 blueberries
Answer: Evaluate 2x2−3x+8 when x=−4 .
Substitute −4 for x. 2(−4)2−3(−4)+8
Simplify exponents. 2(16)−3(−4)+8
Multiply. 32−(−12)+8
Subtract. 44+8
Add. 52
Now we can evaluate expressions that include multiplication and division with integers. Remember that to evaluate an expression, substitute the numbers in place of the variables, and then simplify.
Answer:
60 weeks
Step-by-step explanation:
Factor both numbers 12 and 15:
Find LCM(12,15). The common factor is only 3, multiply ths common factor by all factors that remain. Then
![LCM(12,15)=3\cdot 2\cdot 2\cdot 5=60.](https://tex.z-dn.net/?f=LCM%2812%2C15%29%3D3%5Ccdot%202%5Ccdot%202%5Ccdot%205%3D60.)
This means that the fewest number of weeks that will pass before both machines are cleaned again in the same week is 60 weeks.
