Dimas [21]

Answer:

Part 1: 43.75%

Part 2: 44.07%

Step-by-step explanation:

Hello!

(Pt.1) First, set up a ratio $210/480$ . Next, you use long division I got the percent 43.75. After that, you subtract 6 from the girls group, (because of them moving away and then more coming back.) and 2 from the boys group. Then, you subtract those from the school "population" and you get 472 as the final population. So then you set up another ratio, $208/472$ . I got a percent of 44.07% from that.

For a line that goes through points (2,-2) and (1.-6), what is the equation

sesenic [268]

Answer:

$y + 6 = 4[x - 1]\:or\:y + 2 = 4[x - 2]$

Step-by-step explanation:

First find the rate of change [slope]:

$\frac{-y_1 + y_2}{-x_1 + x_2} = m$

$\frac{2 - 6}{-2 + 1} = \frac{-4}{-1} = 4$

Then plug each of these coordinates into the Point-Slope Formula, $y - y_1 = m[x - x_1].$ Now remember, in this formula, all the negative symbols give the OPPOSITE terms of what they really are, so be EXTREMELY CAREFUL inserting the coordinates into the formula with their CORRECT SIGNS:

$y + 6 = 4[x - 1]\:or\:y + 2 = 4[x - 2]$

I am joyous to assist you anytime.

Two cards are chosen from a standard deck of 52 playing cards without replacement. What is the probability that the first card i

Rashid [163]

For the first draw, the probability of an ace is ( 4 / 52 ).

Now there are only 51 cards left in the deck.

For the second draw, the probability of a king is ( 4 / 51 ).

The probability of both events is

(4/52) (4/41) = (16/2,652)

Divide top and bottom by 4:

(16/2,652) = 4/663 . That's choice-C .
