➷ 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

The y-intercept of f(x) = 5x - 45 would be -45, as that is what is represented in the equation. The way to find the x-intercept would be to solve the equation when f(x) = 0.
0 = 5x - 45
+ 45 + 45
45 = 5x
/5 /5
9 = x
And there we have it.
The intercepts of f(x) = 5x - 45 are as follows:
y-intercept = -45
x-intercept = 9
Hope that helped =)
It would reduce to 16:15
They both share 4 as a common factor. 4 goes into 64, 16 times and 4 goes into 60, 15 times. Therefore allowing 64:60 to reduce to 16:15
Answer:
we have:
∆BDE is similar to ∆BAC
so their side are proportional :
BD/BD=BE/BC
2/BD=4/(6+4)
BD=2×10/4
BD=5
again
BE/BC=DE/AC
4/10=5/AC
AC=5×10/4
AC=25/2
Now,
<u>AC</u><u>=</u><u>2</u><u>5</u><u>/</u><u>2</u><u> </u><u>or</u><u> </u><u>1</u><u>2</u><u>.</u><u>5</u><u>.</u>
<u>AD</u><u>=</u><u>BA-BD</u><u>=</u><u>5</u><u>-</u><u>2</u><u>=</u><u>3</u><u>.</u>
<u>is</u><u> </u><u>your</u><u> </u><u>answer</u><u>.</u>
The answer to the problem is 33
