Hannah and Jenny are selling pies for a school fundraiser. Customers can buy cherry pies and
blackberry pies. Castel sold 13 cherry pies and 1 blackberry pie for a total of $97. Jasmine sold
6 cherry pies and 3 blackberry pies for a total of $93. What is the cost each of one cherry pie and
one blackberry pie?

Answers

Answer:

6 for cherry

19 for blackberry

Step-by-step explanation:

Cherry = x

Blackberry = y

Make system of equations:

Castel:

13x + y = 97

Jasmine:

6x + 3y = 93

Substitution w/ Castel's equation:

y = 97 - 13x

Put into Jasmine's equation

6x + 3(97 - 13x) = 93

6x + 291 - 39x = 93

291 - 33x = 93

-33x = -198

x = 6 $ per Cherry Pie

Plug x = 6 into any equation (choose Castel's):

13(6) + y = 97

y + 78 = 97

y = 19 $ per Blackberry Pie

Solve for the variable

Answers

Answer:

v= 25

Step-by-step explanation:

Try to isolate the variable by getting rid of the 5. Multiply both sides of the equation by 5 to cancel out the 5 on the left side. You are left with 7v= 35(5). Simplified it is 7v= 175. Then to get the v alone, you need to divide both sides by 7 to cancel out the 7 on the left side. You are left with v= 175/7.

This is v= 25

For the graphed function f(x) = (4)x - 1 + 2, calculate the average rate of change from x = 2 to x = 4.

Answers

Answer:

[tex]Average = 30[/tex]

Step-by-step explanation:

Given

[tex]f(x) = 4^{x - 1} + 2[/tex]

Required

Average [tex]rate\ of\ change[/tex] from 2 to 4

This is calculated using:

[tex]Average = \frac{f(b) - f(a)}{b - a}[/tex]

Where

[tex]a= 2[/tex]  and  [tex]b = 4[/tex]

So:

[tex]Average = \frac{f(4) -f(2)}{4 - 2}[/tex]

[tex]Average = \frac{f(4) -f(2)}{2}[/tex]

Calculate f(2) and f(4)

[tex]f(x) = 4^{x - 1} + 2[/tex]

[tex]f(2) = 4^{2-1} + 2[/tex]

[tex]f(2) = 4 + 2[/tex]

[tex]f(2) = 6[/tex]

[tex]f(4) = 4^{4-1} + 2[/tex]

[tex]f(4) = 4^3 + 2[/tex]

[tex]f(4) = 66[/tex]

So:

[tex]Average = \frac{f(4) -f(2)}{2}[/tex]

[tex]Average = \frac{66 - 6}{2}[/tex]

[tex]Average = \frac{60}{2}[/tex]

[tex]Average = 30[/tex]

What is the proportion of times did you roll a 1? (Already answered)
15 Times (This will be your value of p-hat)

1. Say you want to analyze how likely it is that you rolled the proportion of 1s that you did. Would it be appropriate to use a normal model to figure this out? why or why not?


2. Find the probability that the proportion of 1s that you rolled is less than your value of p-hat. Interpret what you find in context.

Answers

Answer:

1. I would think it would be a appropriate to use a normal model to figure this out because sometimes when you are using stuff online you can get the same number like 20 times in a row, whereas, if you use a real dice, you most likely won't roll the same number 20 times.

this is wrong bc i need a problem not only one number what is the problem for "When I triple my number and add four, I get ten. What is my number?" this

Answers

Answer: 2

Step-by-step explanation:

Let's substitute the number as x in the equation.

Triple means you multiply it by 3.

Then you add four, and get 10.

We can write that like this:

3x + 4 = 10

Then subtract 4 from both sides:

3x = 6

And then divide both sides by 3:

x = 2

So the number is 2.

What is the solution to the system of equations? y = x + 3 3x - 4y = -7

Answers

Answer:

x=-5 & y=-2

Step-by-step explanation:

Step 1: Solve y=x+3 for y:

y=x+3

Step 2: Substitute x+3 for y  in 3x-4y =-7:

3x-4y=-7

3x-4(x+3)=-7

-x-12=-7 (Simplify both sides of the equation)

-x-12+12=-7+12 (Add 12 to both sides)

-x=5

-x/1=-5/-1 (Divide both sides by -1)

Step 3: Substitute -5  for x in y=x+3:

y=x+3

y=-5+3

y=-2 (Simplify both sides of the equation)

x=-5 and y=-2

Alberto pagó el año pasado 350 euros por un servicio de teléfono móvil. Si este año ha pagado 378 euros, ¿qué tanto por ciento ha aumentado en el gasto de teléfono móvil?

Answers

Answer:

the percentage increase is 5.3%

Step-by-step explanation:

The computation of the percentage increase is shown below:

= (Current year - last year) ÷ (last year)

= 19  euros ÷ 359 euros

= 5.3%
