A box of cookies contains 4 chocolate and 6 butter cookies. Miguel randomly selects a cookie and eats it. Then he randomly selec

ts another cookie and eats it. Are the probabilities for the flavor of the second cookie that Miguel selects independent of his first selection? Explain. The probabilities for the second cookie selection are independent of the first selection. The cookies are replaced after selecting them. The probabilities for the second cookie selection are dependent on the first selection. The probability of selecting a chocolate cookie second is the same as selecting a butter cookie. The probabilities for the second cookie selection are dependent on the first selection. The probability of a chocolate cookie being selected second is dependent on whether a chocolate or butter cookie was selected first. The probabilities for the second cookie selection

Answer:

The probability of the flavor of the second cookie is always going to be dependent on the first one eaten.

Step-by-step explanation:

Since the number of the type of cookies left depends on the first cookie taken out.

This is better explained with an example:

  1. Probability Miguel eats a chocolate cookie is 4/10. The probability he eats a chocolate or butter cookie after that is <u>3/9</u> and <u>6/9</u> respectively. This is because there are now only 3 chocolate cookies left and still 6 butter cookies left.
  2. In another case, Miguel gets a butter cookie on the first try with the probability of 6/10. The cookies left are now 4 chocolate and 5 butter cookies. The probability of the next cookie being chocolate or butter is now <u>4/9</u> and <u>5/9</u> respectively.

The two scenarios give us different probabilities for the second cookie. This means that the probability of the second cookie depends on the first cookie eaten.

I believe the fastest way to solve this problem is to take any two of the given points and to find the slope and y-intercept of the line connecting those two points.  

Let's choose the 2 given points (-3,16) and (-1,12).
Going from the first point to the second, the increase in x is 2 and the increase in y is actually a decrease:  -4.  Thus, the slope of the line connecting these two points is m = -4/2, or m = -2.

Now use the slope-intercept formula to find the y-intercept, b.

One point on the line is (-3,16), and the slope is m = -2.

Thus, the slope-intercept formula y = mx + b becomes 16 = -2(-3) + b.
Here, b comes out to 10.

So now we have the slope and the y-intercept.  Write the equation:

y = mx + b becomes y=-2x+10.  Which of the four given answer choices is the correct one?

If the factors of quadratic function g are (x − 7) and (x + 3), what are the zeros of function g?
MArishka [77]

Answer: B. -3 and 7

Step-by-step explanation:

To find the zeros, just move the constants to the other side,

x - 7 ⇒ x = 7

x + 3 ⇒ x = -3

If the number is moved to the other side its sign becomes opposite

Hope it helps!

Trina's car uses 12 gallons of gas to travel 144 miles. If she has 6 gallons of gas in the tank, how much more gas will she need
PSYCHO15rus [73]

Answer: 14gallons

Step-by-step explanation:

12gallons/144miles = 1gallon/12miles

Therefore 6gallons = 12*6 = 72miles.

In order to cover 240miles, she will need 240/12 = 20gallons.

20-6 = 14gallons

She will need 14gallons of gas more.

Which of the expressions below has a 1 in the thousandths place of the sum? Select all that apply. A) 32.474 + 16.577 B) 23.452
Paraphin [41]

Answer:

A) 32.474 + 16.577

     = 49.051

C) 19.213 + 4.578

     = 23.791

Step-by-step explanation:

Place value may be defined as the positional system of a notation where the position of any number with reference to the decimal point determines the value of that number.

A) 32.474 + 16.577

     = 49.051

B) 23.452 + 31.561

   = 55.013

C) 19.213 + 4.578

     = 23.791

D) 8.128 + 9.192

   = 17.32

We have to find the expression which contains 1 in the thousandths place in the sum.

We know after the decimal point, the place value are designated as tenths, hundredths, thousandths, and so on.

Therefore, A). 49.051 and C). 23.791 has a place value of 1 in its thousandths place.
