# of broken crayons # of boces
1-5 1
6-10 4
11-15 5
16-20 3
21-25 1
Step-by-step explanation:
1-5: 4 (1 number)
6-10: 6, 6, 8, 9 (4 numbers)
11-15: 12, 13, 14, 14, 15 (5 numbers)
16-20: 17, 17, 19 (3 numbers)
21-25: 24 (1 number)
Answer:
Number of broken crayons Number of boxes
1-5 = 4
6-10 = 9
11-15 = 14
16-20 =19
21-25 =24
Step-by-step explanation:
To find the number of boxes compared to the number of broken crayons you have to find 5 consecutive (hence there being five boxes to fill in) numbers with a constant rate of change. Start with the largest number possible that you can pick and then find the second largest so 24 and 19 the rate of change is 5. Compared to 17 and 19 the rate of change is 2 so it doesn’t have the same rate of change but if you try 19-5 you get 14 which is an option if you subtract 14-5 you get 9 which is another option 9-5 is 4 the lowest number you could possibly pick and they all have a constant rate of change of 5 so the answer is correct.

A local cable company claims that the proportion of people who have Internet access is less than 63%. To test this claim, a random sample of 800 people is taken and its determined that 478 people have Internet access. The following is the setup for this hypothesis test: H0:p=0.63 Ha:p<0.63 Find the p-value for this hypothesis test for a proportion and round your answer to 3 decimal places.
Answers
Answer:
Step-by-step explanation:
For the null hypothesis,
H0 : p = 0.63
For the alternative hypothesis,
Ha : p < 0.63
This is a left tailed test
Considering the population proportion, probability of success, p = 0.63
q = probability of failure = 1 - p
q = 1 - 0.63 = 0.37
Considering the sample,
Sample proportion, P = x/n
Where
x = number of success = 478
n = number of samples = 800
P = 478/800 = 0.6
We would determine the test statistic which is the z score
z = (P - p)/√pq/n
z = (0.6 - 0.63)/√(0.63 × 0.37)/800 = - 1.76
From the normal distribution table, the area below the test z score in the left tail 0.039
Thus
p = 0.039

c) If the height requirements are changed to exclude only the tallest 5% of men and the shortest 5% of women what are the new height requirements
the new height requirements are at least ___ in. and at most ___ in.
(round to one decimal place as needed)
Answers
a) The percentage of women meeting the height requirement is approximately 99.99%.
b) The percentage of men meeting the height requirement is approximately 99.95%.
c) The new height requirements are at least 58.5 inches and at most 71.8 inches.
a) To find the percentage of women meeting the height requirement of being between 4ft 9in (57 inches) and 6ft 4in (76 inches), we need to calculate the proportion of women within this range using the normal distribution.
First, we standardize the height requirement using the formula:
Z = (X - μ) / σ
where X is the value (height), μ is the mean, and σ is the standard deviation.
For the lower limit (57 inches):
Z_lower = (57 - 63.3) / 2.7 ≈ -2.33
For the upper limit (76 inches):
Z_upper = (76 - 63.3) / 2.7 ≈ 4.70
Using a standard normal distribution table or calculator, we can find the area between -2.33 and 4.70. This represents the percentage of women meeting the height requirement.
The percentage of women meeting the height requirement is approximately 99.99%.
b) Similarly, for men meeting the height requirement of being between 4ft 9in (57 inches) and 6ft 4in (76 inches), we standardize the values:
For the lower limit (57 inches):
Z_lower = (57 - 67.3) / 2.8 ≈ -3.68
For the upper limit (76 inches):
Z_upper = (76 - 67.3) / 2.8 ≈ 3.11
Using the standard normal distribution table or calculator, we find the area between -3.68 and 3.11.
The percentage of men meeting the height requirement is approximately 99.95%.
c) To find the new height requirements that exclude the tallest 5% of men and the shortest 5% of women, we need to determine the corresponding Z-scores.
For men:
Z_upper_men = Z(0.95) ≈ 1.645
For women:
Z_lower_women = Z(0.05) ≈ -1.645
Using these Z-scores, we can calculate the new height requirements:
For the new lower limit:
X_lower = Z_lower_women * σ + μ
For the new upper limit:
X_upper = Z_upper_men * σ + μ
Substituting the values:
X_lower = -1.645 * 2.7 + 63.3 ≈ 58.53 inches
X_upper = 1.645 * 2.8 + 67.3 ≈ 71.78 inches
Therefore, the new height requirements are at least 58.5 inches and at most 71.8 inches.

b) The percentage of men meeting the height requirement is 99.95%.
c) The new height requirements are at least 58.5 inches and at most 71.8 inches.
a) For women meeting the height requirement:
Given: Mean (μ) = 63.3 in.
Standard Deviation (σ) = 2.7 in.
So, Minimum height requirement:
= 4 ft 9 in
= 4 * 12 + 9
= 57 inches
and, Maximum height requirement:
= 6 ft 4 in
= 6 * 12 + 4
= 76 inches
We will calculate the Z-scores for these heights using the formula:
Z = (x - μ) / σ
For the minimum height requirement:
[tex]Z_{min[/tex] = (57 - 63.3) / 2.7 ≈ -2.33
For the maximum height requirement:
[tex]Z_{max[/tex] = (76 - 63.3) / 2.7 ≈ 4.70
So, the the area between -2.33 and 4.70.
Thus, the percentage is 99.99%.
b) For men meeting the height requirement:
Given: Mean (μ) = 67.3 in., Standard Deviation (σ) = 2.8 in.
Minimum height requirement: 4 ft 9 in = 57 inches
Maximum height requirement: 6 ft 4 in = 76 inches
For the minimum height requirement:
[tex]Z_{min[/tex]= (57 - 67.3) / 2.8 ≈ -3.68
For the maximum height requirement:
[tex]Z_{max[/tex] = (76 - 67.3) / 2.8 ≈ 3.11
So, the area between -3.68 and 3.11.
Thus, the percentage is 99.95%.
c) For the new height requirements:
For men:
[tex]Z_{upper_{men[/tex] = Z(0.95) ≈ 1.645
For women:
[tex]Z_{lower_{women[/tex] = Z(0.05) ≈ -1.645
For the new lower limit:
[tex]X_{lower} = Z_{lower}_{women} \sigma+ \mu[/tex]
For the new upper limit:
[tex]X_{upper} = Z_{upper}_{men} \sigma+ \mu[/tex]
Substituting the values:
[tex]X_{lower} = -1.645 * 2.7 + 63.3[/tex]
= 58.53 inches
and, [tex]X_{upper} = 1.645 * 2.8 + 67.3[/tex]

A study compared paired daytime and nighttime counts of sea trout, lake trout, and rainbow trout made by the same divers in six lakes during September 2015. Overall, they counted 127 trout during the day and 356 trout at night. The researchers speculate that trout counted at night were present during the daytime but were hidden from view. Biologists should consider that trout behavior and susceptibility to being seen might vary a great deal between daytime and nighttime, even during the summer. In some lakes, the majority of trout may not be seen during the daytime. Determine whether the study is an observational study or an experiment. Justify your answer with specific references to the information in the study.

A box lunch costs b. A bag of chips is $2 extra. Choose the expression to show the cost of 12 lunches with chips and 10 lunches without?
Answers
Answer:
22b+24
Step-by-step explanation:
If a box lunch costs b and a bag of chips is $2 extra then we would have:
box lunch = b dollars
box lunch with bag of chips = b + 2 dollars
Now, we need to find the expression for the cost of 12 lunches with chips and 10 lunches without chips, this would be:
12 lunches with chips = 12 (b + 2)
10 lunches without chips = 10b
Let's sum up and simplify these two expressions:
[tex]12(b+2)+10b\\12b+24+10b\\22b+24[/tex]
Thus, the cost of 12 lunches with chips and 10 lunches without chips is 22b+24

Polynomial function is,
f(x) = x³ - x² - 5x - 3
Possible rational roots of the given function will be = [tex]\frac{\pm1, \pm3}{\pm1}[/tex]
By putting x = -1
f(-1) = (-1)³ - (-1)² -5(-1) - 3
= -1 - 1 + 5 - 3
= 0
Therefore, x = -1 will a root of the given function.
Now we apply synthetic division to get the other roots,
-1 | 1 -1 -5 -3
↓ -1 2 3
1 -2 -3 0
Therefore, factored form of the polynomial will be (x + 1)(x² - 2x - 3).
Now we will find the roots of (x² -2x - 3).
x² - 2x - 3 = x² - 3x + x - 3
= x(x - 3) + 1(x - 3)
= (x + 1)(x - 3)
For roots of the function, f(x) = 0
(x + 1)(x - 3) = 0
x = -1, 3
Therefore, roots of the function are x = -1, 3

Cheryl had 160 stickers more than Gareth. If Cheryl gave 185 stickers
to Gareth, Gareth would have 3 times as many stickers as Cheryl
How many stickers did Gareth have at first?
165
Answers
Answer:
260 stickers
Step-by-step explanation:
Let Gareth's stickers be x.
Hence Cheryl sticker is 160+x;
If Cheryl gave 185 stickers
to Gareth, it means:
Cheryl has at the moment;
160 + x - 185 = x - 25
At this time when Gareth receives 185 he now has:
x+ 185
Also when he receives x +185, he has 3 times Cherry's meaning:
x+185 =3(x-25)
x + 185 = 3x -75
185 + 75 = 3x-2x
260= x
x = 260.
Hence Gareth has 260 stickers

The mean weight of frozen yogurt cups in an ice cream parlor is 8 oz.Suppose the weight of each cup served is normally distributed withstandard deviation 0.5 oz, independently of others.(a) What is the probability of getting a cup weighing more than 8.64oz
Answers
Answer:
10.03% probability of getting a cup weighing more than 8.64oz
Step-by-step explanation:
Problems of normally distributed samples are 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, we have that:
[tex]\mu = 8, \sigma = 0.5[/tex]
What is the probability of getting a cup weighing more than 8.64oz
This is the 1 subtracted by the pvalue of Z when X = 8.64. So
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{8.64 - 8}{0.5}[/tex]
[tex]Z = 1.28[/tex]
[tex]Z = 1.28[/tex] has a pvalue of 0.8997
1 - 0.8997 = 0.1003
10.03% probability of getting a cup weighing more than 8.64oz

Answers
Answer:
C) The auditor may or may not achieve the desired risk of assessing control risk too low.
Step-by-step explanation:
In a concept of risk sampling, if the sample size is chosen randomly in accordance with random selection procedures, the auditor may or may not achieve the desired risk of assessing risk too low. In other words the auditor may or may not achieve desired precision. This is because a samole chosen randomly may not represent the true population.
This depends largely on the sample size. If the sample size selected is too small, the allowance for sampling risk will be larger than what is required because it will lead to a large standard error of the mean
Two barrels are mathematically similar
The smaller barrel has a height of [tex]h[/tex]cm and a capacity of 100 Liters
The larger barrel has a height of 90cm and a capacity of 160 Liters
-Work out the value of [tex]h[/tex]
Answers
Answer:
h ≈ 77 cm
Step-by-step explanation:
Let us convert the liters to cm³.
Smaller barrel
0.001 litres = 1 cm³
100 litres = 100000 cm³
Larger barrel
0.001 litres = 1 cm³
160 litres = 160000 cm³
For a similar solid figure the cube of their corresponding sides is equal to the volume ratio.
This means
h³/90³ = 100000/160000
cube root both sides
h/90 = ∛100000 / ∛160000
h/90 = 46.4158883/54.2883523
cross multiply
54.2883523h = 46.4158883 × 90
54.2883523h = 4177.429947
divide both side by 54.2883523
h = 4177.429947/54.2883523
h = 76.9489175858
h ≈ 77 cm
