A normal distribution has a mean of 15 and a standard deviation of 2. Find the value that corresponds to the 75th percentile.

**Answer:**

The value that corresponds to the 75th percentile is 16.35.

**Step-by-step explanation:**

**Problems of normal distributions 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.

**A normal distribution has a mean of 15 and a standard deviation of 2.**

This means that [tex]\mu = 15, \sigma = 2[/tex]

**Find the value that corresponds to the 75th percentile.**

This is X when Z has a pvalue of 0.75. So X when [tex]Z = 0.675[/tex]

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]0.675 = \frac{X - 15}{2}[/tex]

[tex]X - 15 = 2*0.675[/tex]

[tex]X = 2*0.675 + 15[/tex]

[tex]X = 16.35[/tex]

The value that corresponds to the 75th percentile is 16.35.

1. As long as a few of the animals reproduce the species should survive unless a terrible tragedy were to happen and all of the species lie with a d because their food ran out or their predators Drilled with a k them all. Honestly I am not sure about this question that much an even though these are fifth grade problems I am in fifth grade right now so yeah.

2. I did a quick search about this and I also used some of my logic and it would not make since if animals were to hang out in dry vernal pools. Unless there are animals out in the world that like living in stead plants and dried up water it would not make much since to choose false.

3. Scientists knowledge are growing every day so it is impossible to know everything about one subject because there is always more to learn.

The distance from New York City to Riverhead is approximately 150 miles. On a map whose scale is 24mi= 2inch, what is the distance between the two locations in inches?

**Answer:**

12.5 inches

**Step-by-step explanation:**

**Given**

[tex]Distance = 150\ miles[/tex]

[tex]Scale:= 24\ miles : 2\ inches[/tex]

**Required**

Determine the measurement in inches

**Represent the inches equivalent with d.**

**So, the scale can also be calculated as:**

[tex]Scale:= 150\ miles: d[/tex]

**Equate both scales**

[tex]150\ miles: d = 24\ miles ; 2\ inches[/tex]

**Convert to fraction**

[tex]\frac{d}{150\ miles} = \frac{2\ inches}{24\ miles}[/tex]

[tex]\frac{d}{150} = \frac{2\ inches}{24}[/tex]

**Multiply both sides by 150**

[tex]150 * \frac{d}{150} = \frac{2\ inches}{24} * 150[/tex]

[tex]d = \frac{2\ inches}{24} * 150[/tex]

[tex]d = \frac{2\ inches * 150}{24}[/tex]

[tex]d = \frac{300\ inches}{24}[/tex]

[tex]d =12.5\ inches[/tex]

Determine if the finite correction factor should be used. If so, use it in your calculations when you find the probability. In a sample of 800 gas stations, the mean price for regular gasoline at the pump was $2.816 per gallon and the standard deviation was $0.008 per gallon. A random sample of size 45 is drawn from this population. What is the probability that the mean price per gallon is less than $2.812?

**Answer:**

0.0003 = 0.03% probability that the mean price per gallon is less than $2.812

**Step-by-step explanation:**

To solve this question, we need to understand the normal probability distribution and the central limit theorem.

**Normal probability distribution**

When the distribution is normal, we use 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.

**Central Limit Theorem**

The Central Limit Theorem estabilishes that, for a normally distributed random variable X, with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]s = \frac{\sigma}{\sqrt{n}}[/tex].

For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.

**Finite correction factor:**

If the sample is more than 5% of the population, instead of Central Limit Theorem, we use the finite correction factor, as the standard deviation of the sampling distribution would be too big.

**The mean price for regular gasoline at the pump was $2.816 per gallon and the standard deviation was $0.008 per gallon.**

Large sample, so this can be treated as the population data. Then [tex]\mu = 2.816, \sigma = 0.008[/tex]

**Sample of 45:**

45/800 = 0.056 = 5.6% -> Sample more than 5% of the population, so we use the finite correction factor. This means that s will be multiplied by:

[tex]FCF = \sqrt{\frac{N-n}{N-1}}[/tex]

In which n is the size of the sample(45) and N is the size of the population (800). So

[tex]FCF = \sqrt{\frac{755}{799}} = 0.9721[/tex]

By the Central Limit Theorem, [tex]n = 45, s = 0.9721*\frac{0.008}{\sqrt{45}} = 0.00116[/tex]

**What is the probability that the mean price per gallon is less than $2.812?**

This is the pvalue of Z when X = 2.812. So

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

By the Central Limit Theorem

[tex]Z = \frac{X - \mu}{s}[/tex]

[tex]Z = \frac{2.812 - 2.816}{0.00116}[/tex]

[tex]Z = -3.45[/tex]

[tex]Z = -3.45[/tex] has a pvalue of 0.0003

0.0003 = 0.03% probability that the mean price per gallon is less than $2.812

The smallest angle of a triangle is measure x degrees. The second angle is 45 degrees more than the smallest angle. The third angle is three times larger as the smallest angle. Write algebraic expression to express measures of the second and third angles of the triangle.

**Answer:**

Smallest angle = 27°

Second angle = 72°

Third angle = 81°

**Step-by-step explanation:**

**Given:**

In triangle

Smallest angle = x

Second angle = x + 45

Third angle = 3x

**Find:**

All angle

**Computation:**

Using angle sum property

x + x + 45 + 3x = 180

5x + 45 = 180

x = 27

**Smallest angle = 27°**

Second angle = x + 45

Second angle = 27 + 45

**Second angle = 72°**

Third angle = 3x

Third angle = 3(27)

**Third angle = 81°**

Median = 9

Lower quartile = 7

Upper quartile = 12

**Maximum** = 13

Minimum = 4

**Step-by-step explanation:**

[tex]\frac{1}{4}*\frac{2}{2} =\frac{2}{8} \\\\\frac{3}{8} +\frac{2}{8} =\frac{5}{8}[/tex]

Multiplying by 2/2 is like multiplying by 1, so it doesn't affect the value.

To add fractions with the same denominator just add the numerator, the denominator stays the same.

The **fraction** is 2/8 and the **sum **is 5/8.

The fractional bar is a horizontal bar that divides the numerator and denominator of every fraction into these two halves.

TheGiven:

let the **numerator **be x when **denominator **is 8.

so, 1/4 = x /8

8 = 4x

x= 8/4

x= 2

Now, fraction resulted above is **added **with 3/8

2/8 + 3/8

= (2+3)/8
