Maria has 14 pencils, Ted has 9 pencils, Tom has 12 pencils, Lucinda has 13 pencils, and Jumana has 12 pencils. How can they redistribute the pencils so that they all have the same amount? How many pencils should each person have?
Answer:
12
Step-by-step explanation:
First you have to add the amount of pencils each person has
14 + 9 + 12 + 13 + 12
Which equals 60
Then, you have to divide the total by the answer you got from above

Suppose the monthly charges for cell phone plans in the U. S. Are normally distributed with a mean of $62 and a standard deviation of $10. What is the proportion of cell phone plans charging less than $42 a month for service?
Using the normal distribution, it is found that 0.0228 = 2.28% of cell phone plans charge less than $42 a month for service.
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, the mean and the standard deviation are given by, respectively: [tex]\mu = 62, \sigma = 10[/tex].
The proportion of cell phone plans charging less than $42 a month for service is the p-value of Z when X = 42, hence:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{42 - 62}{10}[/tex]
[tex]Z = -2[/tex]
[tex]Z = -2[/tex] has a p-value of 0.0228.
0.0228 = 2.28% of cell phone plans charge less than $42 a month for service.

Find the measure of each angle in Triangle ABC. m∠a=(50−x)°m∠b=(9x−40)°m∠c=90°
Answer:
40°
50°
90°
Step-by-step explanation:
sum of angle in a triangle is= 180°
(50-x)° + (9x-40)° + 90° = 180°
50-x+9x-40 + 90 = 180
50- 40 +90 -x+9x =180
100 + 8x = 180
8x = 180 -100
8x = 80
x = 80/8 =10
x = 10°
measure of a= (50-x) = 50- 10 = 40°
measure of b = (9x-40)= 90- 40= 50°
measure of c = 90°

The final marked up price is $586.5
What are percentages?A percentage is a number or ratio that can be expressed as a fraction of 100. If we have to calculate the percent of a number, divide the number by the whole and multiply by 100. Hence, the percentage means, a part per hundred. The word percent means per 100. It is represented by the symbol “%”
Given here: Discount %=15 Marked price=$600 and after the sale marked up percentage is 15%
Thus, Discounted price = 600×(1-15%)
= 600× 0.85
=$510

What is the slope of a line perpendicylar to the line whose equation is
5x + 6y = -54. Fully simplify your answer.
Answer:
[tex]\frac{6}{5}[/tex]
Step-by-step explanation:
*Perpendicular lines have negative reciprocals slopes*
First, find the slope-intercept form of 5x + 6y = -54:
5x + 6y = -54
-5x -5x
6y = -5x - 54
