kelby has several pets.she has b, birds,c cats, and f frogs. in this expression b+(c+f) represents the total number of pets kelb

den301095 [7]

Answer:

The number of cats an frogs

Step-by-step explanation:

For some reason the equation has (c+f) grouped off from the rest, since in an equation the first step is to take care of things in the parentheses, first you must add the two together, and based on the description, you know that c is the number of cats and f is the number of frogs. Therefore adding them together would get the total number of cats and frogs.

Luiza's savings account had

Rudik [331]

Answer: g is a geometric sequence.

Step-by-step explanation:

Each year since then, her account accumulated interest amounting to

15% of the balance in the previous year.

15% = 15/100 = 0.15

Since the balance is increasing each year, then the constant factor by which it is increasing is 1 + 0.15 = 1.15.

This factor of 1.15 is a common ratio. This means that the sequence is a geometric sequence since it is increasing by a common ratio.

In a one-way ANOVA, what is the difference between the among-groups variance MSA and the within-groups variance MSW?

LuckyWell [14K]

Answer:

$MSR=MSA=\frac{SSR}{k-1}$

And $MSE=MSW=\frac{SSE}{N-k}$

The difference is that MSA takes incount the variation between the groups and the grand mean, and the MSW takes in count the variation within groups respect to the mean of each group .

Step-by-step explanation:

Analysis of variance (ANOVA) "is used to analyze the differences among group means in a sample".

The sum of squares "is the sum of the square of variation, where variation is defined as the spread between each individual value and the grand mean"

If we assume that we have $j$ groups and on each group from $j=1,\dots,j$ we have $n_j$ individuals on each group we can define the following formulas of variation:

$SS_{total}=\sum_{j=1}^p \sum_{i=1}^{n_j} (x_{ij}-\bar x)^2$

$SS_{between=Treatment}=SS_{model}=\sum_{j=1}^p n_j (\bar x_{j}-\bar x)^2$

$SS_{within}=SS_{error}=\sum_{j=1}^p \sum_{i=1}^{n_j} (x_{ij}-\bar x_j)^2$

And we have this property

$SST=SS_{between}+SS_{within}=6750+8000=14750$

The degrees of freedom for the numerator on this case is given by $df_{num}=k-1$ where k represent the number of groups.

The degrees of freedom for the denominator on this case is given by $df_{den}=df_{between}=N-k$ .

And the total degrees of freedom would be $df=N-1$

We can find the $MSR=MSA=\frac{SSR}{k-1}$

And $MSE=MSW=\frac{SSE}{N-k}$

The difference is that MSA takes incount the variation between the groups and the grand mean, and the MSW takes in count the variation within groups respect to the mean of each group .

And the we can find the F statistic $F=\frac{MSR}{MSE}=$
