3241004551 [841]

Answer:

0.6 is the required probability.

Step-by-step explanation:

We are given the following in the question:

Sample size, n = 250

Probability of accessing internet at work = 37%

P(W)=0.37

Probability of accessing internet at home = 44%

P(H)=0.44

Probability of accessing internet at work and home = 21%

P(W\cap H)=0.21

We have to evaluate the probability that a person in this sample accesses the internet at home or at work.

P(H\cup W) = P(H) + P(W) - P(W\cap H)\\P(W\cup H) = 0.37 + 0.44-0.21\\P(H\cup W)  = 0.6

Thus, 0.6 is the probability that a person in this sample accesses the internet at home or at work

YALL HELP<br> plz give me a fraction problem that contains division and multiplication !!
Luba_88 [7]

Answer:

This one is a bit easy, so if you need a harder one, just let me know.

((32/48) x (4/6)) / (2/5)

Step-by-step explanation:

1) You can simplify both (32/48) and (4/6) to (2/3).

2) Multiply (2/3) by itself, giving (4/9).

3) Dividing by a fraction is equivalent to multiplying by its reciprocal, or opposite. In this example, the reciprocal of (2/5) is (5/2). Thus, (4/9) x (5/2) = (20/18).

4) Simplify your answer, to (10/9) or 1 and 1/9 (as a mixed fraction).

Answer:

260 stickers

Step-by-step explanation:

Let Gareth's stickers be x.

Hence Cheryl sticker is 160+x;

If Cheryl gave 185 stickers

to Gareth, it means:

Cheryl has at the moment;

160 + x - 185 = x - 25

At this time when Gareth receives 185 he now has:

x+ 185

Also when he receives x +185, he has 3 times Cherry's meaning:

x+185 =3(x-25)

x + 185 = 3x -75

185 + 75 = 3x-2x

260= x

x = 260.

Hence Gareth has 260 stickers
