Substitute -8 in for a and 2 for b. Multiply -8 and 2 = -16. -16 / 4 = -4

ab is equal to  a × b

a = -8

b = 2

ab/4 = (-8 × 2) ÷ 4 = -16/4 = -4

the numbers 1,2,3,4, and 5 are written on slips of paper, and 2 slips are drawn at random one at a time without replacet. find t
Tresset [83]

Consider such events:

A - slip with number 3 is chosen;

B - the sum of numbers is 4.

You have to count Pr(A|B).

Use formula for conditional probability:

Pr(A|B)=\dfrac{Pr(A\cap B)}{Pr(B)}.

1. The event A\cap B consists in selecting two slips, first is 3 and second should be 1, because the sum is 4. The number of favorable outcomes is exactly 1 and the number of all possible outcomes is 5·4=20 (you have 5 ways to select 1st slip and 4 ways to select 2nd slip). Then the probability of event A\cap B is

Pr(A\cap B)=\dfrac{1}{20}.

2. The event B consists in selecting two slips with the sum 4. The number of favorable outcomes is exactly 2 (1st slip 3 and 2nd slip 1 or 1st slip 1 and 2nd slip 3) and the number of all possible outcomes is 5·4=20 (you have 5 ways to select 1st slip and 4 ways to select 2nd slip). Then the probability of event B is

Pr(B)=\dfrac{2}{20}=\dfrac{1}{10}.

3. Then

Pr(A|B)=\dfrac{\frac{1}{20} }{\frac{1}{10} }=\dfrac{1}{2}.

Answer: \dfrac{1}{2}.

Find the distance between the points (0,-1) and (0,–11).
Yakvenalex [24]

Answer:

10

Step-by-step explanation:

The formula  is

the square root of  y1-y2 +x1-x2   (square root of everithing)

(-11)-(-1)    + 0-0

(-11) - (-1) = -11 +1  = -10        0-0 = 0

The quare root of  10 squared is 10
