Answer:
The sampled populations have equal variances
Step-by-step explanation:
ANOVA which is fully known as Analysis of variances can be defined as the collection of statistical models as well as their associated estimation procedures which enables easily and effectively analyzis of the differences among various group means in a sample reason been that ANOVA is a total variance in which the observed variance in a specific variable is been separated into components which are attributable to various sources of variation which is why ANOVA help to provides a statistical test to check whether two or more population means are equal.
Therefore the required condition for using an ANOVA procedure on data from several populations for mean comparison is that THE SAMPLED POPULATION HAVE EQUAL VARIANCE.
Answer:
1. 2x - 5 + x = 20
Step-by-step explanation:
Let Aseem's car as x,
Stana's = 5 less than 2x
= 2x - 5
Aseem's + Stana's = 20
x + 2x - 5 = 20
2x - 5 + x = 20

Answer:

Step-by-step explanation:
Given:
The given function in terms of 'a' is given as:

In order to determine
, we need to make
equal to 'x' and find the value of 'a'. Therefore,

Now, plug in the value of 'a' on both sides, we get:

Therefore, the expression for the function in terms of 'x' is:

Present value = 2200
interest rates =5% for 3 years, and 4% afterwards
no. of periods = 7
Future value=2200*(1.05)^3(1.04)^(7-3)
