At the start, Ben and Rick have the same amount of money. Let x represent that amount.
Rick's money: x
Ben's money: x
Then, Ben spends $138.
Rick's money: x
Ben's money: x - 138
At that point, Rick has 4 times the amount that Ben has.
x = 4(x - 138)
x = 4x - 552
552 = 3x
184 = x
Rick has $184.
Answer:
Adults: 938
Teens: 268
Children 12 and under: 469
Step-by-step explanation: Multiply 1675 by each percentage in decimal form:
1675*.56 = 938 adults
1675*.16 = 268 teens
1675*.28 = 469 children 12 and under
8x3 6x4 12x2. so 3 different ways.
Answer:
a) 89%; b) 68%
Step-by-step explanation:
We know that a mean 
and a standard deviation is 
a) Notice that 148 and 184 are each exactly 3 standard deviation away from the mean:
So, we get that at least 
of the men has a height between 148 cm and 184 cm.
b) Notice that 160 and 172 are exactly 1 standard deviation away from the mean.
By the<u> empirical rule</u> , 68% of the men has a height between 160 cm and 172 cm.
Answer: x = 1 so 1/2 - 4/1 + 8 = 0n
