You pick a card at random, put it back, and then pick another card at random. what is the probability of picking a number less than 7 and then picking a 7 when you have 4 card: 4567

.75% of picking up a card under 7 and .25% of picking up a 7.

a.   since the profit made in 2012 is equal to the profit made in 2014, the profit is symmetric about the line y = 120,000.

step-by-step explanation:

93.8

step-by-step explanation:

lets say, first number = x

second number = 3x+7

total = 49

(x)+(3x+7)= 49

4x+7 = 49

4x = 42

x = 42/4

x= 10.5

x= 10.5

3x+7 = 3(10.5)+7 = 93.8

hope this
