A book publisher counted the words on each page of a series of books. They found that the number of words per page followed a normal distribution with a mean of 265 words and a standard deviation of 25 words.
What percentage of the pages contain fewer than 215 words?
Answers
Answer:
The answer is 2.5%
Step-by-step explanation:
Took test on edmentum and made 100%.
2.2% percentage of the pages contain fewer than 215 words.
The normal distribution is defined as a probability distribution that is symmetric about the mean, indicating that data close to the mean are more systematic in occurrence than data distant from the mean. In pictorial form.
The number of words per page in the book is normally distributed, Normal distribution is given as,
[tex]z = \frac{x-\mu}{\sigma}[/tex]
Where, x = number of words per page., µ = mean, σ = standard deviation
From given, µ = 265 words , σ = 25 words
Probability for the number of pages in the book is less than 265 words,
P( x < 215)
For, x = 25,
z = (215-265)/25 = -2
From the normal distribution table, the probability of the z score is 0.022
The percent of pages in the book that are less than 215 words in length is 0.022 × 100 = 2.2%.
Thus, 2.2% percentage of the pages contain fewer than 215 words.

What is the equation of the line that passes through the point (4.11) and is perpendicular to the line with the following equation? OA. y = -x + 14 O B. - r - 15 OD. & 1 + 8
Answers
Answer:
[tex]y = x +7[/tex]
Step-by-step explanation:
Given
[tex]Point\ (x_1,y_1) = (4,11)[/tex]
Perpendicular to [tex]y = -x + 14[/tex]
Required
Determine the line equation
An equation has the form
[tex]y = mx + b[/tex]
Where
[tex]m = slope[/tex]
By comparison with [tex]y = -x + 14[/tex]
[tex]m = -1[/tex]
Because the line is perpendicular to [tex]y = -x + 14[/tex], the following relationship exists
[tex]m_1 = \frac{-1}{m}[/tex] i.e. the condition for perpendicularity
Where m1 is the slope of the equation that passes through [tex]Point\ (x_1,y_1) = (4,11)[/tex]
So, we have:
[tex]m_1 = \frac{-1}{-1}[/tex]
[tex]m_1 = 1[/tex]
The line equation is then calculated using:
[tex]y - y_1 = m_1(x - x_1)[/tex]
Where
[tex]m_1 = 1[/tex]
[tex]Point\ (x_1,y_1) = (4,11)[/tex]
So, we have:
[tex]y - 11 = 1(x - 4)[/tex]
[tex]y - 11 = x - 4[/tex]
Add 11 to both sides
[tex]y - 11+11 = x - 4+11[/tex]
[tex]y = x - 4+11[/tex]
[tex]y = x +7[/tex]

The expression 2a+3b gives the cost (in dollars) for a shirts and b pairs of pants at a garage sale. A. The cost for 1 shirt is $ and the cost for 1 pair of pants is $ . B. The total cost for 5 shirts and 5 pairs of pants is $ . Question 2 c. Is $20 enough to buy 7 shirts and 2 pairs of pants?
Answers
Answer:
Step-by-step explanation:
If 2a+3b gives the cost (in dollars) for a shirts and b pairs of pants at a garage sale
a) To get cost for 1 shirt and the cost for 1 pair of pants, we will substitute a = 1 abd b = 2 into the expression given
Cost = 2(1) + 3(2)
Cost = 2 + 6
Cost = $8
Hence cost for 1 shirt and the cost for 1 pair of pants is $8
b) For the total cost for 5 shirts and 5 pairs of pants;
a = 5 and b= 5
Cost = 2(5)+3(5)
Cost = 10 + 15
Cost = $25
Hence the total cost for 5 shirts and 5 pairs of pants is $25
c) To check whether $20 will be enough to buy 7 shirts and 2 pairs of pants, we will substitute a = 7 and b = 2 into the expression;
Cost = 2(7)+3(2)
Cost = 14 + 6
Cost = $20
Hence $20 will be enough to buy 7 shirts and 2 pairs of pants
A town has a population of 3000 and grows at 4% every year. To the nearest tenth of a year, how long will it be until the population will reach 4700?
Answers
Answer:
14.2 years
Step-by-step explanation:
The town grows 4% (0.04) every year.
3000 x 0.04 = 120, so the town gains 120 people every year.
The town needs 1700 more people to get to 4700.
So, 4700/120= 14.1666666667
That rounds up to 14.2 years.

In a company's first year in operation, it made an annual profit of $277,000. The
profit of the company increased at a constant 18% per year each year. How much
total profit would the company make over the course of its first 5 years of operation,
to the nearest whole number?
Answers
Over the course of its first 5 years of operation, total profit the company would make is $633,709 .
What is a compound interest?"Compound interest is the addition of interest to the principal sum of a loan or deposit, or in other words, interest on principal plus interest."
Given, the annual profit of the company at first year = P =$277,000.
The rate of increase of profit = r% = 18% =0.18.
Total duration = n = 5.
Therefore, after first 5 years of operation, total profit the company would make = P[(1 + r)/100]ⁿ
= $277,000(1 + 0.18)⁵
=$633,708.9
≈$633,709
After 5 years , the total profit would have $633,709.
