Please help!!A bakery sells 5800 muffins in 2010. The bakery sells 7420 muffins in 2015. Write a linear model that represents the number y of muffins that the bakery sells x years after 2010.
The linear model is y= _____ .

Answers

Answer 1
Answer:

points (0 ,5800)

    ( 5,7420)


slope = (y2-y1)/(x2-x1)

   = (7420-5800)/(5-0)  =1620/5=324


point slope form =

y -y1 = m(x-x1)

y-5800 = 324(x-0)

y-5800 = 324x

y = 324x+5800
Answer 2
Answer:

Answer:

y = 324x+5800

Multiply the binomials (3x - 5) and (4x + 6).

Answers

Answer:

12x² - 2x - 30

Step-by-step explanation:

When multiplying binomials, remember to follow the FOIL method:

FOIL =

First

Outside

Inside

Last

Follow FOIL: (3x - 5)(4x + 6)

(3x)(4x) = 12x²

(3x)(6) = 18x

(-5)(4x) = -20x

(-5)(6) = -30

Combine like terms, simplify:

12x² + 18x - 20x - 30

12x² + (18x - 20x) - 30

12x² - 2x - 30

12x² - 2x - 30 is your answer.

Lara tossed a fair coin 3 times. What is the probability of getting heads in the first two trials?1 over 8

I tried 4/8 and I had gotten it wrong!

Answers

The probability of getting heads in the first two trials is 2/8.

What is the probability of getting heads in the first two trials?

Probability calculates the chances that an event would happen. The likelihood of the event occurring lies between 0 and 1. It is zero if the event does not occur and 1 if the event occurs.

Probability of getting heads = heads , heads, tails, tails

This is a 25% probability which is equivalent to 2/8.

4/8 is equal to 1/2. While this is true of one coin toss, it is not a 50% chance if you toss the coin twice. In tossing the coin twice you have the options of: heads, tails, heads, tails (One head and one tail per coin). Since there are four options, it is a 25% chance you will get heads twice in a row. 25% equals 1/4 which equals 2/8.
