Shandra has a bag that contains orange chews, cherry chews, and watermelon chews.
She performs an experiment. Shandra randomly removes a chew from the bag,
records the result, and returns the chew to the bag. Shandra performs the experiment
78 times. The results are shown below:
An orange chew was selected 42 times.
A cherry chew was selected 14 times.
A watermelon chew was selected 22 times.
Based on these results, express the probability that the next chew Shandra removes

b) Find the area to the left of 14.
c) Find the area to the right of 17.
d) Find the area to the right of 19.
e) Find the area between 14 and 30.
Answers
Answer:
a) The area to the left of 18 is 0.5.
b) The area to the left of 14 is if 0.309.
c) The area to the right of 17 is of 0.55.
d) The area to the right of 19 is of 0.45.
e) The area between 14 and 30 is of 0.624.
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 z-score 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, which is the area to the left of X. Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X, which is the area to the right of X.
A variable is normally distributed with mean 18 and standard deviation 8
This means that [tex]\mu = 18, \sigma = 8[/tex]
a) Find the area to the left of 18.
This is the pvalue of Z when X = 18.
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{18 - 18}{8}[/tex]
[tex]Z = 0[/tex]
[tex]Z = 0[/tex] has a pvalue of 0.5.
So the area to the left of 18 is 0.5.
b) Find the area to the left of 14.
This is the pvalue of Z when X = 14. So
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{14 - 18}{8}[/tex]
[tex]Z = -0.5[/tex]
[tex]Z = -0.5[/tex] has a pvalue of 0.309
The area to the left of 14 is if 0.309.
c) Find the area to the right of 17.
This is 1 subtracted by the pvaleu of Z when X = 17. So
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{17 - 18}{8}[/tex]
[tex]Z = -0.125[/tex]
[tex]Z = -0.125[/tex] has a pvalue of 0.45
1 - 0.45 = 0.55
The area to the right of 17 is of 0.55.
d) Find the area to the right of 19.
This is 1 subtracted by the pvaleu of Z when X = 19. So
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{19 - 18}{8}[/tex]
[tex]Z = 0.125[/tex]
[tex]Z = 0.125[/tex] has a pvalue of 0.55
1 - 0.55 = 0.45
The area to the right of 19 is of 0.45.
e) Find the area between 14 and 30.
This is the pvalue of Z when X = 30 subtracted by the pvalue of Z when X = 14.
X = 30
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{30 - 18}{8}[/tex]
[tex]Z = 1.5[/tex]
[tex]Z = 1.5[/tex] has a pvalue of 0.933
From b), when X = 14, Z has a pvalue of 0.309.
0.933 - 0.309 = 0.624
The area between 14 and 30 is of 0.624.
The area to the left of 18 is 0.5, the area to the left of 14 is 0.309, the area to the right of 17 is 0.55, the area to the right of 19 is 0.45, and the area between 14 and 30 is 0.624.
Given :
A variable is normally distributed with a mean of 18 and a standard deviation of 8.
a) Use the z score formula in order to determine the area to the left of 18.
[tex]\rm Z = \dfrac{X-\mu}{\sigma}[/tex]
[tex]\rm Z = \dfrac{18-18}{8}=0[/tex]
For the z = 0 the p-value is 0.5.
Therefore, 0.5 is the area to the left of 18.
b) Use the z score formula in order to determine the area to the left of 14.
[tex]\rm Z = \dfrac{X-\mu}{\sigma}[/tex]
[tex]\rm Z = \dfrac{14-18}{8}=-0.5[/tex]
For the z = -0.5 the p-value is 0.309.
Therefore, 0.309 is the area to the left of 14.
c) Use the z score formula in order to determine the area to the right of 17.
[tex]\rm Z = \dfrac{X-\mu}{\sigma}[/tex]
[tex]\rm Z = \dfrac{17-18}{8}=-0.125[/tex]
For the z = -0.125 the p-value is 0.45.
Therefore, the area to the left of 17 is given by:
= 1 - 0.45 = 0.55
d) Use the z score formula in order to determine the area to the right of 19.
[tex]\rm Z = \dfrac{X-\mu}{\sigma}[/tex]
[tex]\rm Z = \dfrac{19-18}{8}=0.125[/tex]
For the z = 0.125 the p-value is 0.55.
Therefore, the area to the left of 19 is given by:
= 1 - 0.55 = 0.45
e) Use the z score formula in order to determine the area between 14 and 30.
At X = 30 the z score becomes:
[tex]\rm Z = \dfrac{X-\mu}{\sigma}[/tex]
[tex]\rm Z = \dfrac{30-18}{8}=1.5[/tex]
For the z = 1.5 the p-value is 0.933.
For the z = -0.5 the p-value is 0.309.
Therefore, the area to the left of 14 is given by:
= 0.933 - 0.309
= 0.624

What was the total distance, in miles, Eil has biked when he finally reached the library?
Answers
Answer:
Distance covered by Eli is [tex]5\frac{19}{20}[/tex] miles.
Step-by-step explanation:
Eli biked the distance from his home initially = [tex]1\frac{1}{10}[/tex] miles
Then he remembered that he had left a book at home.
He came back home and traveled the distance = [tex]1\frac{1}{10}[/tex] miles
Then he reached the library by traveling the distance = [tex]3\frac{3}{4}[/tex] miles
Total distance covered by him = [tex]1\frac{1}{10}+1\frac{1}{10}+3\frac{3}{4}[/tex]
= [tex]1 + \frac{1}{10}+1+\frac{1}{10}+3+\frac{3}{4}[/tex]
= 5 + [tex]\frac{1}{10}+\frac{1}{10}+\frac{3}{4}[/tex]
= [tex]5+\frac{2}{20}+\frac{2}{20}+\frac{15}{20}[/tex]
= [tex]5+\frac{19}{20}[/tex]
= [tex]5\frac{19}{20}[/tex] miles
Therefore, distance covered by Eli is [tex]5\frac{19}{20}[/tex] miles.
What happens to the volume of a sphere if its radius is multiplied by 6?
Answers
Answer:
216 times the original
Step-by-step explanation:
Volume 1 = 4/3 πr³
volume 2 = 4/3 π(6r)³
v 2 / v 1 = 6³ = 216
When the radius of a sphere is multiplied by 6, the volume is multiplied by 216
How to determine the volume?Let the radius of the sphere be r
The volume of a sphere of radius, r is calculated as:
v = 4/3 πr³
When multiplied by 6, the radius becomes:
R = 6r
The new volume is then calculated as:
V = 4/3 π(6r)³
Divide both volumes
V/v = 4/3 π(6r)³ / 4/3 πr³
Evaluate the quotient
V/v = 6³
V/v = 216
Hence, when the radius of a sphere is multiplied by 6, the volume is multiplied by 216

Step-by-step explanation:
From the graph we can see that the graph is approaching 0 horizontally and 2 vertically but not crossing so we can assumer these are the asymptotes. So the domain goes all the way from -∞ to 2 but does not cross 2 so we have to stop there and create another bracket for 2 to ∞. It is the same process for the range but in the y direction.

Bad Investment After Mrs. Fisher lost 9% of her investment, she had $22,750. What was Mrs. Fisher's original investment?
Answers
Answer:
$2500
Step-by-step explanation:
Given that,
The lost percentage = 9%
Amount she had = $22,750
We need to find Mrs. Fisher's original investment.
As she had lost 9%, it means she will remain with 91% of her investment. Let the original investment is x.
So,
[tex]91\%\ of \ x=22,750\\\\\dfrac{91}{100}x=22,750\\\\x=\dfrac{22,750\times 100}{91}\\\\x=\$25000[/tex]
So, her original investment is equal to $25000.

A sample of 100 women is obtained, and their heights (in inches) and pulse rates (in beats per minute) are measured. The linear correlation coefficient is 0.239 and the equation of the regression line is y = 18.5 + 0.890x, where x represents height. The mean of the 100 heights is 62.9 in and the mean of the 100 pulse rates is 73.4 beats per minute. Find the best predicted pulse rate of a woman who is 65 in tall. Use a significance level of α=0.01 The best predicted pulse rate of a woman who is 65 in tall is_______beats per minute.. (Round to two decimal places as needed.) Answer
Answers
Answer:
54.07 inches
Step-by-step explanation:
Given the regression equation :
y = 18.5 + 0.890x
y = pulse rate in beats per minute
x = height
The best predicted pulse rate of a woman who is 65 inches
Put y = 65 in the regression equation :
65 = 18.5 + 0.890x
65 - 18.5 = 0.890x
46.5 = 0.890x
Divide both sides by 0.890
46.5 / 0.890 = 0.890x / 0.890
54.0697 = x
The best predicted pulse rate for a woman wo is 65 inches tall is 54.07 inches
