A bag contains 12 counters. 7 of them are white. A counter is taken at random and not replaced. A second counter is taken out of
grandymaker [24]
<h3>♫ - - - - - - - - - - - - - - - ~Hello There!~ - - - - - - - - - - - - - - - ♫</h3>

➷ First calculate how many counters are 'not white'

12 - 7 = 5

We have 5 counters that are 'not white'

The probability of taking a white counter the first time is 7/12

For the next pick, there would be 1 less of the total counters as it is not being replaced

The probability of then taking a 'not white' counter is 5/11

The other way you could still get one white counter is:

The first counter (non white) probability would be 5/12

The second counter (white) probability would be 7/11

Multiply these values:

7/12 x 5/11 = 35/132

5/12 x 7/11 = 35/132

Add these two values together:

35/132 + 35/132 = 70/132

Your answer is 70/132

➶ Hope This Helps You!

➶ Good Luck (:

➶ Have A Great Day ^-^

2=-2/7x-6 what is the process
konstantin123 [22]

Answer:

x = - 28

Step-by-step explanation:

Given

2 = - \frac{2}{7} x - 6 ( add 6 to both sides )

8 = - \frac{2}{7} x

Multiply both sides by 7 to clear the fraction

56 = - 2x ( divide both sides by - 2 )

- 28 = x

What is the slope of the line through(-4,2) and (3,-3)?
Nana76 [90]

Answer: -\frac{5}{7}

Step-by-step explanation:

To find the slope of the line, you want to use the formula m=\frac{y_2-y_1}{x_2-x_1}.

m=\frac{-3-2}{3-(-4)} =\frac{-5}{7}

Now we know the slope is -\frac{5}{7}.
