Mean = 25
Standard Deviation = 3.8

Find the value of k.
Round to 2 decimal values.
Answer:
The normal distribution is explained for the solution of this question.
Step-by-step explanation:
Normal Probability Distribution:
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.
Mean = 25, Standard Deviation = 3.8
This means that [tex]\mu = 25, \sigma = 3.8[/tex]
So
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{X - 25}{3.8}[/tex]
If P(X > k) = a
We have to find [tex]X = k[/tex] when Z has a pvalue of 1 - a.
If P(X < k) = a
We have to find [tex]X = k[/tex] when Z has a pvalue of a.

Write the linear inequality shown in the graph. The gray area represents the shaded region. y ≤ –x + 4 y ≤ –x – 4 y ≥ –x – 4 y ≥ –x + 4
For Example:
Write the linear inequality shown in the graph. The gray area represents the shaded region.
A. y ≤ 3x + 4
B. y ≤ 3x – 4
C. y ≥ 3x + 4
D. y ≥ 3x – 4
Answer: C
Step-by-step explanation:
1. The graph indicates that the line intersect the y-axis at -4.
2. Then, you must choose any point that are located within the region and replace them to see if the inequality is satisfied. Therefore, you have:
Point (0,2)

A golf instructor is interested in determining if her new technique for improving players’ golf scores is effective. She takes four (4) new students. She records their 18-hole scores before learning the technique and then after having taken her class. She conducts a hypothesis test. Player 1 Player 2 Player 3 Player 4 Mean score before class 83 78 93 87 Mean score after class 80 80 86 86 This is which of the following and Why? 1. a test of two independent means. 2. a test of two proportions. 3. a test of a single mean. 4. a test of a single proportion.
Answer:
A test of two independent means.
Step-by-step explanation:
The test above is comparing the two independent mean scores (mean before taking her class ; μ1 and mean score after taking her class, μ2. This two mean values are tested to ascertain if there exist any statistical difference between them. This differs from the proportion which is ecekuared by the ratio of success or failure. The single mean and single proportion test only has one group which its mean or proportion is tested.
The null and alternative hypothesis for two independent sample means may be expressed thus :
H0 : μ1 = μ2
Alternative hypothesis
H1 : μ1 ≠ μ2

Answer:
Step-by-step explanation:
From the graph, the initial distance of the cyclist decreases with time before it starts to increase at the same rate.
i. When t = 60 minutes,
distance = (60 -60)
= 0
ii. When t = 120 minutes,
distance = (120 -60)
= 20 km
This implies that the endpoint of the cyclist's race was 20 km from the water station which took 60 minutes. So that on meeting the endpoint, the cyclist cycled back towards the water station at the same rate.

Use the given area of the base and the height to find the volume of the right rectangular prism, in cubic units.
You dident give us a picture of it so we cant tell
What is the surface area of the prism?
Answer:
Step-by-step explanation:
Since we know the total surface area of a prism is equal to the sum of all its faces, i.e., the floor, walls, and roof of a prism. Therefore, the surface area of a prism formula is given as: Total surface area of a prism = 2 x area of the base + perimeter of the base x Height.

Answer:
130/231
Step-by-step explanation:
you just plug in the values of x, y, and z so:
[tex]\frac{-\frac{2}{3}*\frac{5}{7} }{-\frac{11}{13} }[/tex]
start by simplifying the top:
[tex]\frac{-\frac{10}{21}}{-\frac{11}{13} }[/tex]
divide:
[tex]-\frac{10}{21}[/tex]÷[tex]-\frac{11}{13}[/tex]
= [tex]-\frac{10}{21} * -\frac{13}{11}[/tex]
= [tex]\frac{130}{231}[/tex]

A company has 20 employees their average salary is $64,000, and their median salary is $40,000. Which statement is true.
All employees have a salary of about $40,000
$64,000
Between 40,000 to 64,000
Half of the employees earn higher than $40,000
Answer:
The last one, Half of the employees earn higher than $40,000
Step-by-step explanation:
The MEDIAN, or Middle salary is $40,000. That is the numbed that is right between all of the salaries. So since it is in the middle, then half of the people are above it, therefore it is the last one.
