Answer:

$2,400

Step-by-step explanation:

1) lets use the i=prt formula

where i=interest

p=principal

r=rate

t=time

the principal here is $6000(starting amount)

rate is 0.08

and time is 5

I=0.08*5*6000

I=2400

you will gain an interest of $2400

What is the value of x?

Radda [10]

Answer:

Step-by-step explanation:

Applying Pythagoras theorem

Hypotenuse^2=base^2+perp^2

Where base=16

And hypotenuse=34

34^2=16^2+perp^2

1156-256=perp^2

Perp^2=900

Taking square root on both sides

Perpendicular=30

Colin and Brian were playing darts. Colin scored 25. Brian scored 170 more than Colin. What was their combined score?

Elis [28]

Answer:

220

Step-by-step explanation:

We have given that Colin scored 25 and Brian scored x ( x-unknown)

Since we know that Brian scored 170 more than Colin, Brian scored:

x = 25 + 170 = 195

Now we know that Colin scored 25 and Brian scored 195.

They together scored

25 + 195 = 220

To test whether the mean time needed to mix a batch of material is the same for machines produced by three manufacturers, Jacob'

TiliK225 [7]

Answer:

a) Independent variable: The manufacturer. It's a categorical and qualitative variable.

b) Dependent variable: time needed to mix the material, and is a quantitative variable

c) On this case since we want to compare the means of different groups of manufacturers on specific 3 manufacturers (A,B and C) the best way to analyze this is with the ANOVA procedure.

d) ANOVA is the correct procedure since this procedure is used to analyze the differences among group means in a sample, and that's what we want to analyze.

The hypothesis for this case are given by

Null hypothesis: $\mu_{A}=\mu_{B}=\mu_{C}$

Alternative hypothesis: Not all the means are equal $\mu_{i}\neq \mu_{j}, i,j=A,B,C$

Step-by-step explanation:

Previous concepts

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"

Part A

Independent variable: The manufacturer. It's a categorical and qualitative variable.

Part B

Dependent variable: time needed to mix the material, and is a quantitative variable

Part C

On this case since we want to compare the means of different groups of manufacturers on specific 3 manufacturers (A,B and C) the best way to analyze this is with the ANOVA procedure.

Part D

ANOVA is the correct procedure since this procedure is used to analyze the differences among group means in a sample, and that's what we want to analyze.

The hypothesis for this case are given by

Null hypothesis: $\mu_{A}=\mu_{B}=\mu_{C}$

Alternative hypothesis: Not all the means are equal $\mu_{i}\neq \mu_{j}, i,j=A,B,C$

In order to find the mean square between treatments (MSTR), we need to find first the sum of squares and the degrees of freedom.

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

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

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

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

And we have this property

$SST=SS_{between}+SS_{within}$
