Answer:
Q 1) 7$ Q 2) 50 Q 3) 15$
Step-by-step explanation:
1) The cost of 1 claypot = $7
2) Total amount sold to yield the given profit = $1100
3) Amount to sell each pot to make the given profit = $22
We are given that;
Cost of 50 pots = $350
1) Since 50 pots costs $350, the cost of one pot will be;Cost of 1 clay pot = 350/50 = $7 per clay pot
2) She made a profit of $750 on the 50 pots.This means amount she sold in order to make the profit will be;
$350 + $750 = $1,100
3) Since total amount she sold to make the profit is $1,100, then amount each pot was sold to yield that profit on the 50 clay pots will be;1100/50 = $22 per pot

Childhood participation in sports, cultural groups, and youth groups appears to be related to improved self-esteem for adolescents (McGee, Williams, Howden-Chapman, Martin, & Kawachi, 2006). In a representative study, a sample of n = 100 adolescents with a history of group participation is given a standardized self-esteem questionnaire. For the general population of adolescents, scores on this questionnaire form a normal distribution with a mean of μ = 50 and a standard deviation of σ = 15. The sample of group-participation adolescents had an average of M = 53.8.
Does this sample provide enough evidence to conclude that self-esteem scores for these adolescents are significantly different from those of the general population? Use a two-tailed test with α = .05.
Testing the hypothesis, we can conclude that since the p-value of the test is 0.0114 < 0.05, which means that the sample provides enough evidence to conclude that self-esteem scores for these adolescents are significantly different from those of the general population.
At the null hypothesis, we test if the mean is the same of the general population, that is:
[tex]H_0: \mu = 50[/tex]
At the alternative hypothesis, we test if it is different, that is:
[tex]H_1: \mu \neq 50[/tex]
The test statistic is given by:
[tex]z = \frac{M - \mu}{\frac{\sigma}{\sqrt{n}}}[/tex]
For this problem, the parameters are:
[tex]M = 53.8, \mu = 50, \sigma = 15, n = 100[/tex]
Then, the value of the test statistic is:
[tex]z = \frac{M - \mu}{\frac{\sigma}{\sqrt{n}}}[/tex]
[tex]z = \frac{53.8 - 50}{\frac{15}{\sqrt{100}}}[/tex]
[tex]z = 2.53[/tex]
Two tailed test, so the p-value is P(|z| < 2.53), which is 2 multiplied by the p-value of z = -2.53.
Looking at the z-table, z = -2.53 has a p-value of 0.0057
2(0.0057) = 0.0114
The p-value of the test is 0.0114 < 0.05, which means that the sample provides enough evidence to conclude that self-esteem scores for these adolescents are significantly different from those of the general population.

Salaries for teachers in a particular elementary school district are normally distributed with a mean of $41,000 and a standard deviation of $7,200. We randomly survey ten teachers from that district. (Round your answers to the nearest dollar.)
(a) Find the 90th percentile for an individual teacher's salary.
$
(b) Find the 90th percentile for the average teacher's salary.
$
Using the normal distribution and the central limit theorem, it is found that:
a) The 90th percentile for an individual teacher's salary is $50,216.
b) The 90th percentile for the average teacher's salary is $43,914.
In a normal distribution 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]
It 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, which is the percentile of X.By the Central Limit Theorem, the sampling distribution of sample means of size n has standard deviation given by [tex]s = \frac{\sigma}{\sqrt{n}}[/tex].In this problem:
Mean of $41,000, thus [tex]\mu = 41000[/tex].Standard deviation of $7,200, thus [tex]\sigma = 7200[/tex].Item a:
The 90th percentile is X when Z has a p-value of 0.9, so X when Z = 1.28. Thus:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]1.28 = \frac{X - 41000}{7200}[/tex]
[tex]X - 41000 = 1.28(7200)[/tex]
[tex]X = 50216[/tex]
The 90th percentile for an individual teacher's salary is $50,216.
Item b:
Average for a sample of 10, thus [tex]n = 10, s = \frac{7200}{\sqrt{10}}[/tex].
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
By the Central Limit Theorem
[tex]Z = \frac{X - \mu}{s}[/tex]
[tex]1.28 = \frac{X - 41000}{\frac{7200}{\sqrt{10}}}[/tex]
[tex]X - 41000 = 1.28\frac{7200}{\sqrt{10}}[/tex]
[tex]X = 43914[/tex]
The 90th percentile for the average teacher's salary is $43,914.

Deon plans to ride a 15 mile bicycle trail. If his average speed is 20mi/h, which equation can he use to find the time t, in hours, for the ride?
Answer
15=20t
Step-by-step explanation:
Answer:
t = 15 / 20
Step-by-step explanation:
Given:
Distance traveled by Deon to ride a bicycle trail = 15 mile
Average speed of Deon to ride a bicycle trail = 20 mi/hour
Step-by-Step:
Let 'T' be the time taken to ride the bicycle trail.
We will use distance speed formula to write the equation to find the time 'T' in hours, for the ride.
[tex]Distance=\frac{Speed}{Time}[/tex]
Distance = 15 miles
Speed = 20 miles / hour
Time = 15 / 20
Assuming time is t, the formula would be:
t = 15 / 20
"t = 15 mi/ 20 mi/hr " will help Deon calculate the time he will take.
Therefore, t = 15 / 20

Step-by-step explanation:
The amount at the end of March can be found two ways:
add up the deposits for Jan, Feb, Mar:
1200.32 +985.43 +1200.65 = 3386.40
subtract Apr and May from the May total:
6374.72 -1000.98 -1987.34 = 3386.40
The total amount of money that he had deposited into his account at the end of March is $3386.40.

identify the solutions of the inequality 5 ≤ s − 6
Answer:
s≥11
Step-by-step explanation:
5 ≤ s -6
=5 + 6 ≤ s
=11 ≤ s or s≥11
The solution to given inequality 5 ≤ s − 6 for s will be s ≥ 11.
What is inequality?A difference between two values indicates whether one is smaller, larger, or basically not similar to the other.
Inequality is just the opposite of equality for example 2 =2 then it is equal but if I say 3 =6 then it is wrong the correct expression is 3 < 6.
Given the inequality,
5 ≤ s − 6
Subtracting by 5 on both sides,
5 - 5 ≤ s - 6 - 5
0 ≤ s - 11
Adding 11 on both sides
0 + 11 ≤ s - 11 + 11
11 ≤ s or s ≥ 11
Hence "The solution to given inequality 5 ≤ s − 6 for s will be s ≥ 11".

To solve for the value of x
-36 = -3x -4 -5x
Transpose and solve

D. Subtract 15 cents and add 29 cents
Step-by-step explanation:
He should subtract 15 cents and add 29 cents. This is because at 33.85 we estimated to 34 dollars which was 15 cents higher, so we must subtract by 15 to get to the exact cost. We also need to add 29 cents since we rounded down from 16.29 to 16.
A number is doubled and then increased by seven. The result is fifty-one. What is the original number?
Answer: I believe it's 22
Step-by-step explanation:
51 - 7 = 44
If the result is 55 and was increased by 7, you'll subtract 7 from 55 and you'll get 44.
44/2 = 22
To find the number that is doubled and makes up 44, you'll divide 2 from 44 and you'll get 22
