Answer: x^2 -3

That's x squared minus three

Step-by-step explanation:

When you divide 2x^3 by 2x the 2's cancel, and x cubed becomes x squared.

In 6x divided by 2x, the X's cancel and 6 ÷2=3

BTW "cancels" means that a number divided by itself equals one, so it "disappears" from the expression

Anuta_ua [19.1K]

Answer:

66 inches

Step-by-step explanation:

1. Yards to Feet:

1 yard= 3 feet

(6 yards)(3)= 18

6 yards = 18 feet

2. Number of Groups:

30 students/6 students per group= 5 groups

3. Total String Needed:

(5 groups)x(2.5 feet string)= 12.5 feet total string

4. Remaining String:

18 feet-12.5 feet= 5.5 feet

5. Feet to Inches:

1 foot= 12 inches

(5.5 feet)(12)= 66 inches

66 inches of string will remain

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)= $\frac{1}{2} \frac{1}{2} \frac{1}{2}+\frac{1}{2} \frac{1}{2} \frac{1}{2}+\frac{1}{2} \frac{1}{2} \frac{1}{2}=\frac{3}{8}$
