if 26 articles cost $214.50, what amount does 1 article cost? what is the cost of 15 articles?
Answer:
one article costs 8.25$ 15 articles cost 123.75
Step-by-step explanation:
set up a simple equation where a is one article
26a = 214.50
divide by 26 on both sides to isolate the variable
a=8.25
the cost of one article is 8.25
because you then want 15 articles, multiply 8.25 by 15 to get 123.75
The cost of 1 article is $8.25
The cost of 15 articles is $123.75
26 articles = 214.50
1 article= x
cross multiply
26x= 214.50
x= 214.50/26
x= 8.25
1 article= $8.25
15 articles= 15×8.25
= $123.75
Hence 1 article costs $8.25 and 15 articles cost $123.75

what is 4.23 divided by 0.012 ??????????
Answer:
352.5
or
705/2
Step-by-step explanation:
4.23 ÷ 0.012 = 352.5
352.5 × 0.012 = 4.23
When 4.23 is divided by 0.012, we get 352.5.
What is Division? What is division algorithm?Division in maths is the process of breaking a number up into equal parts, and finding out how many equal parts can be made. The division algorithm says when a number [a] is divided by [b], it will give quotient as [q] and remainder [r], then the following relation exist between a, b, q and r as -
a = bq + r
Given are two decimal numbers 4.23 and 0.012 such that → 4.23 divided by 0.012.
Assume that the number -
A = 4.23
B = 0.012
We have to find A/B, therefore, we can write -
A/B = 4.23/0.012A/B = 423000/1200 = 4230/12 = 352.5
Therefore, when 4.23 is divided by 0.012, we get 352.5 as the result.

Scores on the Critical Reading part of the SAT exam in a recent year were roughly Normal with mean 495 and standard deviation 118. You choose an SRS of 100 students and average their SAT Critical Reading scores. The sampling distribution of the average score X-bar is
Answer: sample mean = 495
Step-by-step explanation:
Given that :
Population mean = 495
Population standard deviation = 118
Sample size = 100
The sample mean according to the central limit theorem will be the same as the population mean ; According to the central limit theorem, the sample mean converges to the population mean as the sample size becomes larger, according to the theorem, usually once the SAMPLE size is greater than 30.
Here, the sample size is 100, Hence, the sample mean, will be equal to the population mean.
Sampling distribution of average score = 495 = population mean

(b) The collection of all possible outcomes of a random phenomenon is called A. the sample space. B. the distribution. C. the probability. D. a census. E. None of the above.
Answer:
For question 1, the correct answer is option C
For question 2, the correct answer is option B
Step-by-step explanation:
Problem A
A phenomenon is observed many times, under identical conditions. The proportion of times a particular event occurs is referred to as the probability of the event.
The correct option is C
* Use the instance of the tossing of a coin. The phenomenon that is observed here could be "the face of the coin that shows up after each toss". The number of times this is observed is = number of times the coin is tossed. The phrase "Under identical conditions" would mean that the coin is tossed in an identical manner e.g. 6feet high each time. The proportion of times a particular event (either HEAD showing up or TAIL showing up) occurs is the probability of that event's occurrence!
Problem B
The collection of all possible outcomes of a random phenomenon (in a given experiment) is called the distribution of the random phenomenon.
The correct option is B

This week a very large running race 5K occurred in Denver the times were normally distributed with a mean of 23.92 minutes and the standard deviation of 3.4 minutes what time in minutes is the cut off for the fastest 51.99% and what percent of runners took more than 32.128 minutes to complete the race
Answer:
a) 24.09 minutes
b) 0.8%
Step-by-step explanation:
This week a very large running race 5K occurred in Denver the times were normally distributed with a mean of 23.92 minutes and the standard deviation of 3.4 minutes what time in minutes is the cut off for the fastest 51.99%
Z score for 51.99% = 0.05
z = (x-μ)/σ,
where x is the raw score = ? minutes
μ is the population mean = 23.92 minutes
σ is the population standard deviation = 3.4 minutes
0.05 = x - 23.92/3.4
Cross Multiply
0.05 × 3.4= x - 23.92
0.17 = x - 23.92
0.17 + 23.92 = x
x = 24.09 minutes
What percent of runners took more than 32.128 minutes to complete the race
= z score
z = (x-μ)/σ,
where x is the raw score = 32.128 minutes
μ is the population mean = 23.92 minutes
σ is the population standard deviation = 3.4 minutes
z = 32.128 - 23.92/3.4
z = 2.41412
P-value from Z-Table:
P(x<32.128) = 0.99211
P(x>32.128) = 1 - P(x<32.128) = 0.0078867
Approximately =0.008
Converting to percentage = 0.008 × 100
= 0.8%
Using the normal distribution, it is found that:
The cut off for the fastest 51.99% of times is of 24.09 minutes.0.25% of runners took more than 32.128 minutes to complete the race.Normal Probability DistributionIn 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.In this problem, we have that the mean and the standard deviation are, respectively, [tex]\mu = 23.92, \sigma = 3.4[/tex].
The cut off for the fastest 51.99% is the lowest 51.99% of times, that is, the 51.99th percentile, which is X when Z = 0.05.
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]0.05 = \frac{X - 23.92}{3.4}[/tex]
[tex]X - 23.92 = 0.05(3.4)[/tex]
[tex]X = 24.09[/tex]
The cut off for the fastest 51.99% of times is of 24.09 minutes.
The proportion of runners who took more than 32.128 minutes to complete the race is 1 subtracted by the p-value of Z when X = 32.128, hence:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{32.198 - 23.92}{3.4}[/tex]
[tex]Z = 2.43[/tex]
[tex]Z = 2.43[/tex] has a p-value of 0.9925.
1 - 0.9925 = 0.0025.
0.0025 = 0.25% of runners took more than 32.128 minutes to complete the race.

Average human hair = 3 x 10⁻³ inches
Unknown:
How many times longer is a mile than a human hair;
Solution:
Since we know that a mile 6 x 10⁴ inches , we can compare this quantity to the human hair;
Number of times = [tex]\frac{6 x 10^{4} }{3 x 10^{-3} }[/tex]
Number of times = 2 x 10⁴⁺³
Number of times = 2 x 10⁷

Answer:
a. R(t) = 2t - 500
b. D(t) = 400 + 10t
c. T(t) = 400 + 10t + 2t -500
Step-by-step explanation:
donations: $400; every person costs: $10; raffle ticket: $2; winner: $500
a. R(t) = 2t - 500
2t is the raffle tickets. t represents each person. -500 represents the money that the school loses for giving away the money to the winner.
b. D(t) = 400 + 10t
400 is the pre-donation that they had. 10t is the fee for entering the dinner per person. t represents each person.
c. T(t) represents all the money the school will gain (and lose) from the fundraiser. This stands to reason that T(t) is a combination of R(t) and D(t) since R(t) is the raffle and D(t) is the donations and dinner.
T(t) = 400 + 10t + 2t -500

Adrian shops for school clothes and spends a total of $93.42. If the local tax rate is 8%, how much was the cost without taxes?
Answer:
85.95
Step-by-step explanation:
If the local tax was 8% and we want to know what is was without the tax then we need to do 93.42 times .92
[tex]93.42*.92=85.9464[/tex]
Since money only goes to the hundredths place we need to round there
[tex]85.95[/tex]
Based on the amount that Adrian spent in total, the cost without taxes was $86.50.
The cost of the clothes was $93.42 including tax.
Assuming the original cost is x, the equation is:
Total cost = Original cost x ( 1 + tax)
Solving would give:
93.42 = x × (1 + 8%)
93.42 = 1.08x
x = 93.42 / 1.08
= $86.50
In conclusion, the cost without taxes was $86.50.

According to the Empirical rule, when data is normally distributed then 95% of the lies within 2 standard deviations from mean.
Given: The distribution of the heights of students in a large class is roughly bell-shaped ( i.e. Normally distributed).
The average height is 68 inches, and approximately 95% of the heights are between 62 and 74 inches.
Then, by Empirical rule, 68 -2(standard deviations) =62 [lower limit]
⇒ 2(standard deviations)= 68-62 = 4
⇒ standard deviations=2
Hence, correct option is a. 2
Answer:
B-3
Step-by-step explanation:
According to the empirical rule, roughly 95% of the distribution is within 2 standard deviations of the mean.
The mean is 68. The distance from 62 to 68 is 6 inches
68-62=6
Cut that in half to get 6/2 = 3
