Four students about to purchase concert tickets for $20.00 for each ticket discover that they may purchase a block of 5 tickets
CaHeK987 [17]

Answer:

Each student's contribution = $17

Each student will save $ 3

Step-by-step explanation:

Cost of the block of 5 tickets is $85.00.

Dividing the $ 85 by 5 would give the equal amount each would have to contribute.

$ 85/5=$ 17

Each will have to pay $ 17 to buy a block of 5 tickets for $85.00.

We can find the amount each will save by subtracting the amount to be shared by the 5 students from the amount paid by the 4 students.

They will save

$ 20-$17=

$3

Each of them will save $3 if they can get a fifth person to join them and the 5 people equally divide the price of the 5-ticket block.

A box of oatmeal must contain 16 oz. The machine that fills the oatmeal boxes is set so that, on the average, a box contains 16.
Vadim26 [7]

Answer:

29. 15.87%

30.  4.75%

31. 0.62%

32. probability cannot be calculated (0%)

Step-by-step explanation:

We have that the formula of the normal distribution is:

z = (x - m) / sd

where x is the value we are going to evaluate, m is the mean and sd is the standard deviation

x = 16 and m = 16.5

when sd = 0.5

z = (16 - 16.5) /0.5

z = -1

Now when looking in the z table, we have that the corresponding value is 0.1587, that is, the probability is 15.87%

when sd = 0.3

z = (16 - 16.5) /0.3

z = -1.67

Now when looking in the z table, we have that the corresponding value is 0.0475, that is, the probability is 4.75%

when sd = 0.2

z = (16 - 16.5) /0.2

z = -2.5

Now when looking in the z table, we have that the corresponding value is 0.0062, that is, the probability is 0.62%

when sd = 0

z = (16 - 16.5) / 0

z = infinity

probability cannot be calculated
