Answer:  

answer is b. 7/19

Step-by-step explanation:

A: event of drawing first white card

P(A)= 2/5

B/A: event of drawing second white card given first white card has been drawn

we have to find P(B/A)

A∩B: event of drawing two white cards without replacement

P(A∩B)=14/95

baye's theorem says that

P(A∩B)=P(A)×P(B/A)

14/95=P(B/A)×2/5

⇒P(B/A)=7/19

hence,<u> answer is b. 7/19</u>

The bonus would be worth $493,000.

3.4% = 3.4/100 = 0.034; 3.4% of 14500000 = 0.034(14500000) = 493000.

Yo i need help wit 17 and 18 i’ll give u a brainliest you please

Answer:

17. See below

18. 750

Step-by-step explanation:

17. Since the lollipops are being sold at the same price, 50 cents, for each one sold, they make a constant amount of money. For each increase in lollipops sold, there is a constant increase in money made, and thus the situation is a linear function.

18. To solve this equation, let's say y is the money made at the convention in dollars and x is the number of lollipops sold. If the principal gave them 125 dollars before they sold any lollipops (0 lollipops sold), then 125 is the y-intercept of the function, and in the equation y=mx+b, b=125. If each lollipop costs 50 cents (half of a dollar), then for each lollipop, x, sold, .5 dollars are made and are added to the profit, y. Thus, .5 dollars is the slope. The equation then becomes:

y=0.5x+125

Now, if they need 500 dollars, y is thus equal to 500 dollars. Solving the equation:

500=0.5x+125

500-125=0.5x

375=0.5x

\frac{375}{0.5} =x

375*2=x

750=x

Thus, 750 lollipops must be sold.

How do you this??<br><br> Scientific notation
Airida [17]
So Scientific Notation is a "simplified version" of a number. For example, is your number is 2,345, the scientific notation would be 2.345 * 10³. 

If it was 0.023, then the scientific notation would be 2.3 * 10^-2. 

Scientific notation is found by moving the decimal place to the left or right, until only one digit is left to the left of the decimal; it has to be greater than 1, but less than ten. If you move the decimal place to the right, it's a negative power of 10. If you move it to the left, it is a positive power of 10.


Hope this helps!
