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
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:
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?
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.

Grace rolls a fair, 6-sided die 50 times.
What is the probability that she rolls at least one 6?
Round your answer to 4 decimal places.
O 0.0001
0.1389
0.3333
0.9999
Answer:
Step-by-step explanation:
Here's the thing. It is easier to figure out the probability of not getting a six even once during the 50 rolls.
The chance of that happening is (5/6)^50 = 0.00010988
So the probability is succeeding is (1 - 0.00010988) = 0.9999 rounded to 4 places.
Answer:

7) Mr. Lopez is planting a flower garden. He has 18 red roses and 6 yellow roses. Which ratio compares the number of yellow roses to the total number of roses in the garden? *
Answer:
6:24 or 1:3 (this is reduced)
Step-by-step explanation:
I added 18 plus 6 together getting 24, which tells me that there are 24 flowers in Mr. Lopez's garden. I then set up the ratio as 6:24, but i knew that i could reduce it. (I'm noy sure if you want it reduced or not) So I divided both sides by 6 getting the ratio 1:3.

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
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)
