A cylinder has volume 78 cm³. What is the volume of a cone with the same radius and height?​
OleMash [197]

Answer:

The volume of the cone is 26\ cm^{3}

Step-by-step explanation:

we know that

The volume of a cylinder is equal to

V=\pi r^{2}h

In this problem we have that

V=78\ cm^{3}

so

78=\pi r^{2}h -----> equation A

The volume of a cone with the same radius and height is equal to

V=\frac{1}{3}(\pi r^{2}h) -----> equation B

Substitute equation A in equation B

V=\frac{1}{3}(78)

V=26\ cm^{3}

The sum of three numbers is 1. If the second number is subtracted from the sum of the first and third numbers, the result is -5.
Sladkaya [172]

Answer:

final answer:

a (first number) = - 4

b (second number) = 3

c (third number) = 2

Step-by-step explanation:

1. put the equation in numbers and letters:

   a + b + c = 1

  (a + c) - b = - 5

  (a + b) - c = - 3

2. Use one of the equations to solve the other

A large department store examined a sample of 18 credit card sales and recorded the amounts charged for each of three types of c
Leokris [45]

Answer:

d. 2 in the numerator, 15 in the denominator

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 3 groups and on each group from j=1,\dots,n_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}=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  

We want to test this hypothesis:

\mu_{Master card}=\mu_{Visa}=\mu_{Discover}

And we have this property  

SST=SS_{between}+SS_{within}  

The degrees of freedom for the numerator on this case is given by df_{num}=df_{within}=k-1=3-1=2 where k =3 represent the number of groups.

The degrees of freedom for the denominator on this case is given by df_{den}=df_{between}=N-K=18-3=15.

And the total degrees of freedom would be df=N-1=18 -1 =17

On this case the correct answer would be 2 for the numerator and 15 for the denominator.  

d. 2 in the numerator, 15 in the denominator
