Answer:

I did the first page you asked for just now! :)

Step-by-step explanation:

20) 15 = 3r R = 5

21) k/2 = 6 K = 12

22) 3h = 27 H = 9

23) j/3 = 4 J = 12

24) 6p = 30 P = 5

25) n/10 = 40 N = 400

26) h/4 = 15 H = 60

27) 9/s = 81 S = 9

28) 14 = 2c C = 7

29) 26 = 13d D = 2

30) 6 = m/3 M = 18

31) 7 = p/5 P= 35

32) 4w = 16 W = 4

33) f/3 = 9 F = 27

34) 20 = 4x X = 5

35) 3z = 36 Z = 12

36) 10 = j/6 J = 60

6x+1 = -8x-13 pleasee

DiKsa [7]

Answer: $x=-1$

Add 8x to both sides

$6x+1+8x=-8x-13+8x\\14x+1=-13$

Subtract 1 from both sides

$14x+1-1=−13-1\\14x=-14$

Divide both sides by 14

$14x/14=-14/14\\x=-1$

The probability of none will have high blood pressure if twenty percent of Americans age 25 to 74 have blood pressure .If 16 ran

andriy [413]

Answer:

The probability that none will have high blood pressure is 0.0281

Step-by-step explanation:

The correct question is as follows;

Twenty percent of Americans ages 25 to 74 have high blood pressure. If 16 randomly selected Americans ages 25 to 74 are selected, find each probablility. a. None will have high blood pressure

This is a binomial problem. We shall solve in that line

The probability of success is 20% or 0.2 [(Americans ages 25 to 74 have high blood pressure)] p = 0.2

The probability of failure q is thus 1-p = 1-0.2 = 0.8

The probability of none is thus;

P(X= 0) = 16C0 p^0 q^16

= 16C0 * 0.2^0 * 0.8^16 = 0.0281

What is the solution of the system of equations y =2x - 3

kherson [118]

Answer:

-37/5= y

x=11/5

Step-by-step explanation:

4x-3y=31

-3y=-4x+31 regroup it to match the other

-2 y=(2x-3)(-2) multiply by -2 to get -4x

-3y=-4x+31

-2y=-4x+6 adding

-5y=37 divide

-37/5= y

4x-3(-37/5)=31

x=11/5
