Answer:

You could talk on the phone for 200 minutes at night, or 40 minutes during the day.

For every 5 minutes you reduced your night time talking, you could talk during the day for 1 minute.

Step-by-step explanation:

0.50d + 0.10n < $20

0.50d < $20 --> d < 40 minutes

0.10n < $20 --> n < 200 minutes

A vending machine automatically pours soft drinks into cups. The amount of soft drink dispensed into a cup is normally distribut
klemol [59]

Answer:

Step-by-step explanation:

Since the amount of soft drink dispensed into a cup is normally distributed, we would apply the formula for normal distribution which is expressed as

z = (x - µ)/σ

Where

x = amount in ounce of soft drink dispensed into cup.

µ = mean amount

σ = standard deviation

From the information given,

µ = 7.6oz

σ = 0.4 oz

a) The probability that the machine will overflow an 8-ounce cup is expressed as

P(x > 8) = 1 - P(x ≤ 8)

For x = 8,

z = (8 - 7.6)/0.4 = 1

Looking at the normal distribution table, the probability corresponding to the z score is 0.84

P(x ≤ 8) = 1 - 0.84 = 0.16

b) P(x< 8) = 0.84

c) when the machine has just been loaded with 848 cups, the number of cups expected to overflow when served is

0.16 × 848 = 136 cups
