Find the percent of all values in a normal distribution for which z ≤ 1.00, to the nearest tenth of percent.
Answer:
84.1% of all values in a normal distribution have z ≤ 1.00.
Step-by-step explanation:
Problems of normally distributed samples can be solved using the z-score formula.
In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the zscore of a measure X is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.
In this question:
The percent of all values in a normal distribution for which z ≤ 1.00.
This is the pvalue of Z = 1.
Z = 1 has a pvalue of 0.8413.
Converting to percentage, to the nearest tenth.
84.1% of all values in a normal distribution have z ≤ 1.00.

A candle maker adds lemon oil to wax to make the lemon-scented candle shown. How many ounces of oil will he need for the candle to have 0.0025 ounces of oil per cubic centimeter of wax.
Answer:
The ounces of oil needed is 5 ounces of oil
Step-by-step explanation:
The first thing to do here is to calculate the volume of the lemon-scented candle given.
Looking at shape the volume can be calculated using the formula L * B * H
where L(length) = 10cm , B(breadth) = 8cm and Height(h) = 25cm
The volume V is thus = 10 * 8 * 25 = 2,000 cm^3
The ounces of oil needed for the candle to have 0.0025 ounces of oil per cm^3 of wax will be = The volume of the lemon-scented candle * 0.0025 ounces of oil per cm^3 of wax
That will be = 0.0025 * 2,000 = 5 ounces
Answer:
5 ounces

Hi, I need help. I have a question about the Big Bang and Evolution. I don't fully understand or believe what happened. Can someone with a great mind try to explain it. Good luck by the way, I will tell you what I think in the comments. I don't believe in the Big Bang, I doubt you can convince me, but if you are willing to try..........please do.
Answer:
The big bang is showing that there is tiny atoms. The atoms grouped up with gravity and more and more grouped making a super dense dot. The dot exploded making gases creating stars. The stars were bigger so they got new atoms to join creating planets. One planet named was suitable for life so tiny germs. The rest nobody knows.

Marsha has two cubes with one number on each side,each cube is numbered from 1 to 6 marsha rolls both number cubes at the same time. What is the probability that the total of numbers facing up will equal 12
Answer:
1/36
Step-by-step explanation:
If the cubes are numbered from 1 to 6 there is just one way that the sum of both of them equals 12 and this is when Marsha gets 6 in the first cube and 6 in the other.
Thus, to know what the probability that the total of numbers facing up will equal 12 we would have to calculate the probability that the first cube is 6 AND the second one is also 6.
The probability that the first cube has the number 6 is: 1/6
The probability that the second cube has the number 6 is: 1/6
We need to multiply this numbers because they both have to be 6 (rule of multiplication),
so: [tex]\frac{1}{6}(\frac{1}{6} )= \frac{1}{36}[/tex]
Thus, the probability that the sum of them equals 12 is 1/36

How much tomato juice is needed for a group of 4 people if each person gets ⅓ cup of juice? How much tomato juice is needed if they each get ⅔ cup of juice?
Answer:
1. At 1/3 cup per person, the amount of tomato juice needed is [tex]1\tfrac{1}{3} \ cups[/tex] of tomato juice
2. At 2/3 cup per person, the amount of tomato juice needed is [tex]2\tfrac{2}{3} \ cups[/tex] of tomato juice
Step-by-step explanation:
1. Here we have that each person gets 1/3 cup of juice
Number of people in the group = 4
Amount of tomato juice each person gets = 1/3 cup
Total amount of tomato juice required = 4 × 1/3 = 4/3 cups of tomato juice
In proper fractions, we have;
Total amount of tomato juice required = [tex]1\tfrac{1}{3} \ cups[/tex] of tomato juice.
2. Where we have that;
Amount of tomato juice each person gets = 2/3 cup
Number of people in the group = 4
∴ Total amount of tomato juice required = 4 × 2/3 = 8/3 cups of tomato juice
In proper fractions, we have;
Total amount of tomato juice required = [tex]2\tfrac{2}{3} \ cups[/tex] of tomato juice.

Carlos has 4/5 of a tank of fuel in his car. He uses 1/10 of a tank per day.
How many days will his fuel last.
Answer:
8 days.
Step-by-step explanation:
To solve this, we will need to divide fractions to find the amount of days his fuel will last. Remember that when dividing fractions, you need to multiply by the reciprocal of the fraction.
We can do this by:
[tex]\frac{4}{5} * \frac{10}{1} = \frac{40}{5} = 8[/tex]
Therefore, his gas will last 8 days.
Answer:
8
Step-by-step explanation:
number of days=total fuel÷consumption per day
=(4/5)÷(1/10)
=4/5 ×10/1
=8 days

Suppose compact fluorescent light bulbs last, on average, 11,500 hours. The distribution is normal and the standard deviation is 400 hours. What percent of light bulbs burn out within 12,300 hours?
Answer:
2.275%
Step-by-step explanation:
The first thing to do here is to calculate the z-score
Mathematically;
z-score = (x-mean)/SD
from the question, x = 12,300 hours , mean = 11,500 hours while Standard deviation(SD) = 400 hours
Plugging the values we have;
z-score = (12,300-11,500)/400 = 800/400 = 2
Now, we want to calculate P(z ≤ 2)
This is so because we are calculating within a particular value
To calculate this, we use the z-score table.
Mathematically;
P(z ≤ 2) = 1 - P(z > 2) = 1 - 0.97725 = 0.02275
To percentage = 2.275%

the lines below are parallel. If the green line has a slope of 5, what is the slope of the red line? Enter your answer as an integer or fraction in lowest terms
Answer: 5
Step-by-step explanation: As a rule, parallel lines will always have the same slope. What that means is that if you're told that 2 lines are parallel, the slopes will be exactly the same for both of them.
So if the green line has a slope of 5, the red
line also has a slope of 5.

What is the volume of a cylinder with base radius 2
and height 9?
Answer:
18
Step-by-step explanation:
volume= r × h = 2 × 9= 18
Answer:
The volume is 144[tex]\pi[/tex].
Step-by-step explanation:
In order to calculate the volume of a cylinder, you have to find the area of it's base. Because a cylinder's base is a circle, you use the formula A=[tex]\pi r{2}[/tex]. Substituting in the radius's length would be A=[tex]\pi (4){2}[/tex], which is A=16[tex]\pi[/tex]. Now that we know the base area of the cylinder, we multiply it by the height, which is 9 to calculate the volume. Therefore, the volume of the cylinder would be 9×16[tex]\pi[/tex], which is 144[tex]\pi[/tex].
