By definition of conditional probability,

P(<em>F</em> | <em>E</em> ) = P(<em>F</em> and <em>E</em> ) / P(<em>E</em> )

Then

P(<em>F</em> and <em>E </em>) = P(<em>F</em> | <em>E</em> ) P(<em>E </em>) = 0.5 • 0.2 = 0.1

HOW TO ADD 5 5\6+2 2\3 =
dybincka [34]

Answer: 8.50

Step-by-step explanation: I like to turn fractions into deciamls.

5/6 = .83  (I get 0.83 by 5 divided by 6)

2/3 = .66  (I also got 0.66 by 2 divided by 3)

.8333 + .66 = 149 = 1.49333

5 + 2 = 7 + 1.49 = 8.49

Now round up 8.49333 and you'll get 8.50 or 8 ¹/²

Let me know if I'm wrong, have a good day!

0.4b+1.3=0.4(b-5) solve equation
Ivan

Answer:

Step-by-step explanation:

At first sight this equation has 3 terms.  Multiply all 3 of them by 10 to remove the fractions:

4b + 13 = 4(b - 5)

Carrying out the multiplication, we get:

4b + 13 = 4b - 20

This can never be true (13 is never equal to -20), so this equation has NO SOLUTION.

Select 2 statements that are true about the equation y+6=-10(x-3).
natta225 [31]

Answer:

(1) and (4)

Step-by-step explanation:

The equation of a line in point- slope form is

y - b = m(x - a)

where m is the slope and (a, b) a point on the line

y + 6 = - 10(x - 3) is in this form

with slope m = - 10 → (1)

(a, b) = (3, - 6) → (4)

Here are the percents of the popular
RoseWind [281]

Ok, you should first order every number in the regular order (1,2,3,4,5,6,7,and so on) or (1.2,1.3,2.4,5.9).

43.2, 43.4, 47.9, 49.2, 49.6, 49.7, 50.1, 50.7, 51.2, 53.9, 55.1, 57.4, 58.8, 60.7, 61.1.

Median means the exact middle and here there are total of 15 different numbers so we know this is going to be easier if this was even. 50.7 is the median because it is in the middle and there are an even number of numbers on each side to it, 7.
