Sheer Industries is considering a new computer-assisted program to train maintenance employees to do machine repairs. In order to fully evaluate the program, the director ofmanufacturing requested an estimateof the population mean time required for maintenance employees to complete the computer assisted training. Use 7.94 days as a planning value for the population standard deviation. (Round your answers up to the nearest whole number).
(a) Assuming 95% confidence, what sample size would be required to obtain a margin of error of 0.5 days?
(b) If precision statement was made with 90% confidence, what sample size would be required to obtain a margin of error of 3 days?
Answer: (a) n = 900
(b) n = 18
Step-by-step explanation: Margin of Error represents the percentage of confidence your result will be different from the real population value.
It is calculated as
[tex]E=z\frac{\sigma}{\sqrt{n}}[/tex]
z is z-score related to the percentage of confidence
σ is population standard deviation
n is sample size
(a) Margin of error = 0.5
For a 95% confidence, z-score is 1.96.
Sample size will be:
[tex]E=z\frac{\sigma}{\sqrt{n}}[/tex]
[tex]\sqrt{n}=\frac{z\sigma}{E}[/tex]
[tex]\sqrt{n}=\frac{1.96*7.64}{0.5}[/tex]
[tex]\sqrt{n} =30[/tex]
n = 900
For a 95% confidence, margin of error of 0.5 days, sample size required would be 900.
(b) Margin of error = 3
z-score for 90% confidence = 1.645
Solving for sample size:
[tex]\sqrt{n}=\frac{z\sigma}{E}[/tex]
[tex]\sqrt{n}=\frac{1.645*7.64}{3}[/tex]
[tex]\sqrt{n}=4.2[/tex]
n = 18
It would be required, to obtain a margin of error of 3 days, a sample size of 18 maintenance employees.

the ratio of birth to the population of a certain town last year was 32:1000
I) if the number of birth in the town was 384 children, what was the number of population in that town
Answer and Step-by-step explanation:
We are told that the birth-population ratio last year was 32:1000
This year, it is 384. This number was multiplied by 12 from 32.
So, we should multiply 1000 by 12, which results us with 12000.
So, the ratio would be:
384:12000

Heather opened a lemonade stand on her street. It costs her $5.25 to buy the supplies each day, and she sells lemonade for $1.50 a cup. If she wants to make at least $100.00 in profits (sales - expenses) each day, what is the minimum number of cups of lemonade Heather needs to sell? Input your answer as a whole number.
Answer:
Answer: 71 cups
Step-by-step explanation:
71 x 1.5 = 106.5 - 5.25 = 101.25
Plz mark me brainliest
Answer:
100=1.50x-5.25
105.25=1.50x
x=70.167
so to get at least $100 a day she'd have to sell 71 cups
David has $15 to spend at the gourmet candy store. He wants to buy gummy bears and jelly beans. Gummy bears are 5.25 per pound and jelly beans are 3.90 per pound. If David already has 1 3/4 pounds of jelly beans, how many pounds of gummy bears can he buy?
Answer:
1[tex]\frac{39}{70}[/tex] pounds
Step-by-step explanation:
To find the remaining amount of money available left to buy gummy bears, we need to find the amount of money already spent on jelly beans.
Amount of money spent on jelly beans = 1[tex]\frac{3}{4}[/tex] × 3.90
= 6.825
Amount of money left for gummy bears = 15-6.825
= 8.175
Pounds of gummy bears bought = 8.175 ÷ 5.25
= 1[tex]\frac{39}{70}[/tex] pounds
If David already has 7/4 pounds of jelly beans, then 1.55 pounds of gummy bears can he buy.
What is the unitary method?The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value.
To determine the remaining amount of money available left to buy gummy bears, we have to find the amount of money already spent on jelly beans.
Amount of money spent on jelly beans;
= 7/4 × 3.90
= 6.825
Amount of money left for gummy bears ;
= 15-6.825
= 8.175
Thus Pounds of gummy bears bought = 8.175 ÷ 5.25
= 1.55 pounds
Hence, If David already has 7/4 pounds of jelly beans, then 1.55 pounds of gummy bears can he buy.

If you divide any known side of PQRS by the same side on ABCD, it will equal 1.4. So if you did 49/35 or 56/40, each time you would get 1.4. Then, you just multiply 1.4 with RSs similar side, which is CD. 1.4 multiplied by 30 equals 42.

Answer:
[tex]\displaystyle \frac{7\frac{3}{4}}{\frac{1}{4}}=31[/tex]
Step-by-step explanation:
Fractions
We are given the expression:
[tex]\displaystyle \frac{7\frac{3}{4}}{\frac{1}{4}}[/tex]
We'll find an equivalent expression that results when simplifying the given fraction.
The numerator is a mixed fraction, which we'll convert into an improper fraction as follows:
[tex]7\frac{3}{4}=7+\frac{3}{4}=\frac{4*7+3}{4}=\frac{31}{4}[/tex]
Now it follows:
[tex]\displaystyle \frac{7\frac{3}{4}}{\frac{1}{4}}=\frac{\frac{31}{4}}{\frac{1}{4}}[/tex]
Instead of dividing fraction, we multiply by the reciprocal of the denominator:
[tex]\displaystyle \frac{7\frac{3}{4}}{\frac{1}{4}}=\frac{31}{4}\cdot \frac{4}{1}[/tex]
Simplifying:
[tex]\mathbf{\displaystyle \frac{7\frac{3}{4}}{\frac{1}{4}}=31}[/tex]
Add and subtract, whichever comes first, from left to right.

Melissa's garden is 40 feet wide when the length is 24 feet.
Melissa's garden has an area of 40 feet2 when the length is 24 feet.
Melissa's garden has dimensions 40 feet by 24 feet.
Answer:
Melissa's garden has an area of 40 feet² when the length is 24 feet
Step-by-step explanation:
The point, (24, 40), shown on the graph suggests that, Melissa's garden with a length of 24 ft, has an area of 40 ft².
The 24 is on the x-axis which is representing length of the garden. While 40 is on the y-axis represents the area of the garden.

write the equation of the line parallel to the line below and passes through (-1,0)
parallel to the line with the points (0,3) and (1,0)
Answer:
y = -3x - 3
Step-by-step explanation:
Going from the point (0,3) to the point (1,0), we see that the rise (change in y) is -3 and the run (change in x) is 1. Thus, the slope of the new line is
m = rise/run = -3/1 = -3.
Using the coordinates of the given point (-1, 0), we'll find the equation of this line in point-slope form:
y - 0 = m(x + 1), or y = -3(x + 1), or (in slope-intercept form) y = -3x - 3
The cost of buying salad from a salad bar is at least $4.50 per pound. Which inequality represents the price per pound of salad? A. x > 4.50 B. x = 4.50 C. x < 4.50 D. x > 4.50
Answer:
The cost of buying salad per pound) is more than or equal to $4.50.
Step-by-step explanation:
The inequality represents the cost of at least $4.50 will be x ≥ 4.50 thus option (A) is correct.
What is inequality?A difference between two values indicates whether one is smaller, larger, or basically not similar to the other.
In other words, 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.
As per the given,
The cost of salad is at least $4.50 thus means it is the minimum cost so x ≥ 4.50 refers to the cost equal and more than $4.50.
Hence "The inequality indicates that the price will be x ≥ 4.50, which must be at least $4.50".

Find the z-table here.
17.11%
37.07%
62.93%
82.89%
Answer:
i think is the last one
Step-by-step explanation:
72.99% of days have a high temperature between 66 and 80 degrees.
What is temperature?It is the degree or intensity of heat present in a substance or object, especially as expressed according to a comparative scale and shown by a thermometer or perceived by touch.
here, we have,
Let random variable x denote the daily temperature in a variation resort city.
then E(x) = μ = 75
and S.D. = √var(x) = σ = 6
x is approximately normal
x ≈ N(75, 6²)
then Z = (X - 75) / 6
Z ~ N(0,L)
P(66< x < 80) = P((66-75 / 6) < (x - 75 / 6) < 20 - 75 / 6)
= P( -1.5 < z < 0.23), where Z = (x - 75 / 6)
=P(z<0.23) - P(z ≤ -1.5)
= 0.7967 - 0.0668
= 0.7299
P(66< x < 80) = 0.7299
Therefore, 72.99% of days have a high temperature between 66 and 80 degrees.

If you look at the table, y has a row under the x row. Each of the boxes have numbers, and it's a so-called "pattern graph." A says, "The value of the function at x = 0 is y = 3." That means that the number 0 in the "x-row" has a 3 in the "y-row" (or below that number. That's all there is to it, and you just repeat this except different numbers, however... C and D aren't horizontal from each other so they are incorrect.
