Simplify. 17 – 6 × 10 ÷ 2 + 12

Katarina [22]

Use PEMDAS.

17-(6×10÷2)+12

6×10=60 divide by 2 to get 30

now: 17-30+12
17-30=-13
-13+12=-1

The price of an item has been reduced by 35%. The original price was $60. What is the price of the item now?

Hatshy [7]

Answer:

$39

Step-by-step explanation:

the original price which is $60 represents 100%

it has been reduced by 35%

100% - 35%= 65%

0.65 × $60 = $39

Suppose a family has three children of different ages. We assume that all combinations of boys and girls are equally likely. (a)

Ivan

Answer:

a) There are 8 possible combinations and each probability is 1/8.

b) The probability that it is a boy given that there are two girls is 3/8

Step-by-step explanation:

a) The sample space is given by:

BBB (3 boys)

BBG (Boy, boy, girl)

BGB (Boy, girl, boy)

BGG (Boy, girl, girl)

GBB (girl, boy, boy)

GBG (girl, boy, girl)

GGB (girl, girl, boy)

GGG (3 girls)

The probability of each combination is the same:

P(BBB)=P(B∩B∩B)= $\frac{1}{2} \frac{1}{2} \frac{1}{2}=\frac{1}{8}$

2) There are three possible combinations in which there are 2 girls and 1 boy:

BGG, GBG, GGB

So the probability is given by:

P(BGG ∪ GBG ∪ GGB)= $\frac{1}{2} \frac{1}{2} \frac{1}{2}+\frac{1}{2} \frac{1}{2} \frac{1}{2}+\frac{1}{2} \frac{1}{2} \frac{1}{2}=\frac{3}{8}$
