Answer:
It is used when there are two independent variables in the experiment.
Step-by-step explanation:
The one way analysis of Variance statistical test is employed when we intend to analyze the variation in the mean of levels or groups of an independent variable. It allows us check for convergence of data. The variable here is usually categorical and must have 3 or more levels, hence, the groups could be infinite in count. A one way ANOVA will have only ONE independent variable, For data with two independent variables, the TWO way ANOVA statistical test is employed.
using the difference quotient method f(x+h) - f(x)/h
1-10(x+h)-1-10t
1-10x-10h -1-10
-10 h/h = -10
so the answer is -10
Answer:
a) 4/5
b) 1/3
Step-by-step explanation:
Put the numbers in the formula and evaluate.
a) pitch = (rise)/(1/2·span)
= (12 ft)/(1/2·30 ft) = 12/15 = 4/5
___
b) pitch = (4 ft)/(1/2·24 ft) = 4/12 = 1/3
Answer :
C
Explanation:
It is C because it simplifies down to 5x+5x.
Answer:
Step-by-step explanation:
<u>Standard Deviation and Variance</u>
If we have a data set of measured values the variance is defined as the average of the squared differences that each value has from the mean. The formula to calculate the variance is:
Where 
is the mean of the measured values xi (i running from 1 to n), and n is the total number of values.
The standard deviation is known by the symbol 
and is the square root of the variance. We know the standar deviation of the weight in kg of a group of teenagers to be 8.6 kg. Thus, the variance is
