Answer:

Step-by-step explanation:

a1 = -2x + 7

d = 4x + 1 - (-2x + 7)

d = 4x + 1 + 2x - 7

d = 6x - 6

n = 8

a8 = -2x + 7 + (n-1)*d

a8 = -2x + 7 + (8 -1 ) * (6x - 6)

a8 = -2x + 7 + 7 * (6x - 6)

a8 = -2x + 7 + 42x - 42

a8 = 40x - 35

Anit [1.1K]

Answer:

Your question was incomplete, as the values are not given.

I guess these are the values you are talking about.

Hair Type   Brown   Blond   Black    Red    Totals

Wavy           20           5          15         3        43

Straight        80          15         65        12       172

Totals          100         20         80        15       215

Now w have to find out the probability of a child with red, straight hair.

Total no of children with straight hair are = 172

The children having straight red hair = 12

The probability of selected child = 12/172.

Natalka [10]
Hey there! :) How are you? Basically what you said is right. 

Question 1: There are 16 oz (ounces) in a pound, so we do 64/16= 4 lbs (pounds). 

Question 2: If Jack has 3 pounds of pasta, that would mean he has 48 ounces, since 1 pound is 16 oz, so 16*3= 48 ounces. 

Hoped I helped! Have a nice day, and keep smiling! :)
