CONDITIONAL PROBABILITY URGENT?
a_sh-v [17]

Let the event A=\{ Horse \}, B=\{ Female \}

The the probability of the events

P(A \cap B)=\frac{2}{14+26} =\frac{1}{20}

P( B)=\frac{26}{14+26} =\frac{13}{20}

The conditional probability

P(Horse|Female)=P(A|B)=\frac{P(A \cap B)}{P(B)} =\frac{1/20}{13/20} =\frac{1}{13}

(HURRY) Janet is mixing a 15% glucose solution with a 35% glucose solution. This mixture produces 35 liters of a 19% glucose sol
Arturiano [62]

Answer:

c. 28 liters

Step-by-step explanation:

Given tha tJanet is mixing a 15% glucose solution with a 35% glucose solution. This mixture produces 35 liters of a 19% glucose solution. Now we need to find about how many liters of the 15% solution is Januet using in the mixture.

Let the number of liters of the 15% solution is Januet using in the mixture = x

Let the number of liters of the 35% solution is Januet using in the mixture = y

Then we get equations:

x+y=35...(i)

and

(15% of x) + (35% of y) = 19% of 35.

or

0.15x+0.35y=0.19(35)

15x+35y=19(35)

3x+7y=19(7)

3x+7y=133 ...(ii)

solve (i) for x

x+y=35

x=35-y...(iii)

Plug (iii) into (ii)

3x+7y=133

3(35-y)+7y=133

105-3y+7y=133

105+4y=133

4y=133-105

4y=28

y=28/4

y=7

plug y=7 into (iii)

x=35-y=35-7=28

Hence final answer is c. 28 liters

I need answer Immediately!!!!!!!
Dennis_Churaev [7]

Answer:

y= 5x - 3

Step-by-step explanation:

For the slope, use this formula (y2 - y1) / (x2 - x1)

I used (1,2) and (2,7) from the chart

plug 7 for y2, and 2 for x2

then plug 2 for y1, and 1 for x1

7-2 / 2-1 = 5/1 = 5    <-- this is the slope.

Find the y intercept by plugging in (1,2) into y=5x + b

2 = 5(1) +b

2= 5 + b  (subtract 5 on both sides)

-3 = b

So the answer is y= 5x - 3
