Pedro buys lunch at school every day. He always gets pizza when it is
available. The cafeteria has pizza about 80% of the time.
Pedro runs a simulation to model this using a random number generator. He
assigns these digits to the possible outcomes for each day of the week:
• Let 0 and 1 = no pizza available
Let 2, 3, 4, 5, 6, 7, 8, and 9 = pizza available
The table shows the results of the simulation.

What is the estimated probability that Pedro will eat pizza for lunch every day
next week?
O A. 0.0
B. 0.3
OC. 0.4
D. 0.7

Answer is B: 0.3

Reason: in each box, there are 5 digits to represent the 5 days in a week. There’s 10 boxes to represents 10 weeks. In each box there’s a chance out of 5 for Pedro to get pizza. You multiply each days possibly of Pedro getting pizza by each other n get about .26 & round it to .3 - hope that helps! ((:

Answer:

16 4/7

Step-by-step explanation:

First, you cant subtract 3/7 from 6/7 so take 1 from 19, which turns it to 18. And add that one to 3/7 to get 10/7, or just add 7 to your numerator. So now you have 18 10/7 - 12 6/7. so subtract 18 - 12 to get 6, and the subtract 10/7 - 6/7 to get 4/7. You dont actually have to subtract the denominator just the numerators, because the denominatos are the same so you leave them just the way they are. I hope this helps :)

Answer:

18.5 in approx

Step-by-step explanation:

Given data

aspect ratio of 16: 9

L= 16in

W= 9 in

We want to find the diagonal of the TV

applying Pythagoras theorem

d^2= l^2+w^2

d^2= 16^2+ 9^2

d^2=256+81

d^2= 337

d= √337

d= 18.35 in

Hence the tv is 18.5 in approx

Explanation:

Think of 6 + y - 3 as 6 + 1y - 3

y and 1y are the same thing because 1 times any number is that same number.

The coefficient is the number to the left of the variable, so the coefficient is 1.

Answer:

154

Step-by-step explanation:

The expression is  [tex]f(x)=4x^2-7x+7[/tex] and we know that  [tex]f(x)=f(7)[/tex]. Therefore, you will have to substitute x with 7.

Calculations:

[tex]f(x)=4x^2-7x+7[/tex]

[tex]f(7)=4(7)^2-7(7)+7[/tex]

[tex]4(49)-49+7= 154[/tex]

Answer:

I think that you need to plug 7 in to the x's

Yes it looks very weird, but if you don't think that is right, Use the 7 for the F's.

Answer:

Step-by-step explanation:

Answer:

length: 38 feet

width: 10 feet

area: 380 ft²

Step-by-step explanation:

The scale between the drawing and the actual studio is 2 in : 5 ft. If we divide both sides by 2, we find that the scale is 1 in : 2.5 feet.

For the first number, 15.2 inches, if we multiply it by 2.5 and change the label to "feet", we can find the real length.

15.2 * 2.5 = 38.

The length is 38 feet.

For the width, do the same thing.

4 * 2.5 = 10

The width is 10 feet.

Area is length times width. So if we plug in the numbers we just found:

38 * 10 = 380.

The area is 380 ft²

Step-by-step explanation:

The monthly rent during the 8th year of living in the apartment will be $2160.

A linear system is one in which the parameter in the equation has a degree of one. It might have one, two, or even more variables.

You rent an apartment that costs $800 per month during the first year, but the rent is set to go up by $170 per year.

Then the monthly rent during the 8th year of living in the apartment will be

Let y be the monthly rent and x be the number of years.

Then we have

y = 170x + 800

The rent after 8 years, then the rent will be

y = 170 × 8 + 800

y = 1360 + 800

y = $ 2160

Thus. the monthly rent during the 8th year of living in the apartment will be $ 2160.

Answer:

6 race cars

Step-by-step explanation:

In this scenario, there would be a total of 6 race cars on the scale. Since each racecar weighs 1/4 pound then 4 racecars would equal 1. This leaves us with 1/2 or 0.5 pounds left. This would be 2 race cars since 2/4 is equal to 0.5 pounds. Therefore, if we add these two amounts up it would be a total of 6 racecars (4+2) which would total 1 1/2 pounds.

Answer:

  x

Step-by-step explanation:

There is already an expression given for x, so that is the easiest variable to substitute for.

Substituting for x using the second equation, you have ...

  -3(-2y+14) +y = -14

  6y -42 +y = -14

  7y = 28

  y = 4

  x = -2(4) +14 = 6

The solution is (x, y) = (6, 4).

_____

Substitution for x is the easiest.

__

The first equation could be rearranged to give an expression for y:

  y = 3x -14

Then that can be used to substitute for y in the second equation. My lazy brain judges that to be more work.
