You would have 2/10 chance of choosing the sugar cookie then after you chosen it 5/9 chance of picking up a peanut butter cookie. I hope this helps

Answer:

1/9

Step-by-step explanation:

The total number of cookies is

2 sugar cookies+ 5 peanut butter cookies+ 3 chocolate chip cookies= 10

We want to take a sugar cookie

P(sugar cookie) = # sugar cookie/total cookies

                          = 2/10 = 1/5

Now we eat the cookie (not replacing it) so there are only 9 cookies

1 sugar cookies+ 5 peanut butter cookies+ 3 chocolate chip cookies= 9

Now we want a peanut butter cookie

P(peanut butter  cookie) = # peanut butter cookie/total cookies

                          = 5/9

To get the probability of both events happening, multiply them together

P( sugar, peanut) = 1/5 * 5/9

                            = 1/9

Determine the standard form of the equation of the line that passes through (-6,6) and (3,-2)
Simora [160]

Answer:

y=(8/9)x + 4 and 2/3

Step-by-step explanation:

the slope of this line:

change in y/change in x

change in y=6-(-2)=8

change in x=-6-3=-9

change in y/change in x= 8/9

8/9 is the slope, so you plug it in for m in the standard form equation. You then use one point's x and y values to substitute for x and y in the equation, and solve for b, which is the y intercept

y=mx+b

y=(8/9)x+b

-2=(8/9)*3+b

-2=8/3+b

-4 and 2/3=b

Answer:

Part 1) The inequality that represent this situation is 5(x+7)^{2} \geq1,050  or  5x^{2}+70x+245 \geq1,050

Part 2) Yes, 8 inches is a reasonable width for his tablet

Step-by-step explanation:

Part 1)

Let

L -----> the length of the screen television

W ----> the width of the screen television

x ---->  the width of Andrew's tablet

we know that

L=5W ------> equation A

W=x+7 ----> equation B

The area of the television is

A=LW -----> equation C

Substitute equation A and equation B in equation C

A=5(x+7)(x+7)

A=5(x+7)^{2}

5(x+7)^{2} \geq1,050

5(x^{2}+14x+49) \geq1,050

5x^{2}+70x+245 \geq1,050 ------> inequality that represent this situation

Part 2) Determine if 8 inches is a reasonable width for his tablet

For x=8 in

Substitute in the inequality

5(8+7)^{2} \geq1,050

5(15)^{2} \geq1,050

1,125 \geq1,050 -----> is true

therefore

Yes, 8 inches is a reasonable width for his tablet
