Elsa wants to build a snowman. Elsa only has 20 Frozen energies to make them. Each large snowman requires 5 Frozen energies and a small snowman requires 2 Frozen energies. Anna's display area is 48 f t2 . A large snowman takes up 10 f t2 and a small snowman takes up 8 f t2 . What are the number of small and large snowmen Elsa and Anna can make?

Answers

48/8=8  this means Elsa can create a minimum of 8 small snowmen to cover the display area. 8x2=16 which means Elsa would have 4 spare frozen energies. OR 10 can go into 48 a maximum of 3 times to make LARGE snowmen without using all her energy but not enough to cover the display area. 48-30=18 Elsa still has five energies left so she can build two SMALL snowmen giving her a total of 16 with a remainder of two square feet uncovered. OR Elsa can make two large snowmen (covering 20 square feet and leaving her 10 energies left) and make five small snowmen which would cover a total of 40 square feet. 40+20=60 which is too much. 60-48=12. If Elsa made four small snowmen instead of five it would equal 32. 32+20=52 which is still too much. If Elsa made three small snowmen instead of four it would equal 24. 24+20= 44 which isn't enough to fill the display.

We know that

[tex]\frac{6}{25}[/tex]

Is the same as

6÷25

Then, using long division gives us

0.24

Lastly, multiplying 0.24 by 100 gives us

An experiment was conducted as a one-way factorial design with K sample means, each based on n scores. What is the number of degrees of freedom for the between mean squares

Answers

Answer:

The mean squares has d.f (n-1)

Step-by-step explanation:

The total number of degrees of freedom is n-1 as there is only one restriction of computing the grand mean. The d.f for k samples is k-1 beacuase the mean of the sample means must equal the grand mean. Similarly , the d.f for within SS is n-k , due to the k restrictions of computing the k sample means. Hence we find that

Total df= Within df + Between df

n-1=  (n-k)+(k-1)

Between SS has (k-1) d.f

Within SS has (n-k) d.f

These two quantities are known as mean squares and has d.f (n-1)

Toby bought 8 hotdogs and 5 fries. It cost $34.00
Bernie bought 2 hotdogs and 6 fries. It cost $18.00
What is the cost of one hotdog and the cost of one order of fries?
Students, draw anywhere on this slide!
Peor Decanteractive

Answers

Answer:

Each hot dog = $3

Each french fry = $2

Step-by-step explanation:

First, lets define our variables:

x = Hotdog

y = fries

Next, you need to set up a cost equation for both Toby and Bernie:

8x + 5y = 34

2x + 6y = 18

Now, we need to isolate one of the variable:

2x + 6y = 18

2x = 18 - 6y

x = 9 - 3y

Next, we need to insert this equation back into the first equation (8x+5y = 34) to find the cost of y (fries):

8x +5y = 34

8 (9-3y) + 5y = 34

72 - 24y + 5y = 34

72 - 19y = 34

19y = 38

y or fries = $2

Finally, we need to find the cost of each hotdog by using the cost of fries ($2) in one of the formulas:

2x + 6y = 18

2x + 6(2) = 18

2x + 12 = 18

2x = 6

x or hotdog = $3

Step-by-step explanation:

Slope can be found by using the following equation. Note that [tex]m[/tex] is slope:

[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]

Let:

[tex](x_1 , y_1) = (-3 , -5)\\(x_2 , y_2) = (3 , 5)[/tex]

Plug in the corresponding numbers to the corresponding variables:

[tex]m = \frac{5 - (-5)}{3 - (-3)}[/tex]

Note that when two negative signs are directly next to each other, they become a positive. Add across:

[tex]m = \frac{5 + 5}{3 + 3} = \frac{10}{6}[/tex]

[tex]m = \frac{10}{6}[/tex]
