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

A scientist estimated that a mixture would need 4 milliliters of a chemical to balance. The actual amount needed was 7 millilite
Butoxors [25]

42.86% error was in the scientist's estimation.

Step-by-step explanation:

Given data;

Approx amount = 4 ml

Exact amount needed = 7 ml

Percentage error = \frac{|Approx-Exact|}{Exact}*100

Percentage\ error=\frac{|4-7|}{7}*100\\Percentage\ error=\frac{|-3|}{7}*100\\Percentage\ error=\frac{3}{7}*100\\\\Percentage\ error=\frac{300}{7}\\Percentage\ error= 42.86\%

42.86% error was in the scientist's estimation.

Keywords: error, percentage

How do I find the measure of these two supplementary angles using algebra?
nikdorinn [45]

Answer:

70 and 110

Step-by-step explanation:

The two angles add to 180 degrees since they form a straight line

2x+10 +3x+20 =180

5x+30 = 180

Subtract 30 from each side

5x+30-30 =180-30

5x = 150

Divide by 5

5x/5 =180/5

x = 30

The left angle is 2x+10 = 2*30+10 = 60+10 =70

The right angle is 3x+20 = 3*30 +20 = 90+20 = 110

Describe the graph of y = |x - 2| + 4
Usimov [2.4K]

Answer:

Step-by-step explanation:

Note that this function resembles the absolute value function y = |x|.

The graph of y = |x| has its vertex at (0, 0) and opens up in a v-shape.

The graph of y = |x - 2| looks the same as that of y = |x|, but the entire graph has been translated 2 units to the right.

The graph of y = |x - 2| + 4 is that of y = |x - 2|, translated 4 units up.
