Mila’s Sandwich Shop sells sub sandwiches in four sizes. The probabilities that a customer will order a 6-inch, 9-inch, or 12-inch sandwich from the shop are shown in the table. A 2-column table with 4 rows. Column 1 is labeled sandwich size with entries 3-inch, 6-inch, 9-inch, 12-inch. Column 2 is labeled probability with entries question mark, 0.25, 0.30, 0.33.

What is the probability that a customer orders a 3-inch sandwich?

0.12
0.25
0.30
0.33
0.88

1/4 and 8/3 because:

the reciprocal if 4 is 1/4 because 4 is used as 4/1 and the opposite of that is 1/4. the opposite of 3/8 is 8/3 so that is the answer.

x =±sqrt(1/3)

step-by-step explanation:

x+4/6x=1/x

multiply each side by 6x to get rid of the fractions

6x*(x+4/6x)=1/x*6x

distribute

6x^2 +4 = 6

subtract 4 from each side

6x^2 +4-4 = 6-4

6x^2 =2

divide by 6

6x^2/6 = 2/6

x^2 = 1/3

take the square root of each side

sqrt(x^2) = ±sqrt(1/3)

x =±sqrt(1/3)

x + 4/7
