Step-by-step explanation:
Centerpieces are normally distributed with mean of 30 ounces and standard deviation of 2 ounces. The weights of the shipping boxes are normally distributed with mean of 12 ounces and standard deviation of 1 ounce. Suppose that centerpieces are chosen at random and packed into randomly chosen shipping boxes.If a package exceeds 45 ounces, an additional charge is incurred. What is the proportion of packages will incur such a charge
Answer:
0.0901 = 9.01% of packages will incur such a charge
Step-by-step explanation:
Normal Probability Distribution:
Problems of normal distributions can be solved using the z-score formula.
In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the zscore of a measure X is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
The Z-score 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. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.
Sum of normal variables:
When we add normal variables, the mean will be the sum of the means, while the standard deviation is the square root of the sum of the variances.
Centerpieces are normally distributed with mean of 30 ounces and standard deviation of 2 ounces.
This means that [tex]\mu_C = 30, \sigma_C = 2[/tex]
The weights of the shipping boxes are normally distributed with mean of 12 ounces and standard deviation of 1 ounce.
This means that [tex]\mu_S = 12, \sigma_S = 1[/tex]
Suppose that centerpieces are chosen at random and packed into randomly chosen shipping boxes.
The shipment is given by the centerpice plus the shipping box. So the mean and the standard deviation of the weight are given by:
[tex]\mu = \mu_C + \mu_S = 30 + 12 = 42[/tex]
[tex]\sigma = \sqrt{\sigma_C^2 + \sigma_S^2} = \sqrt{2^2 + 1^2} = \sqrt{5} = 2.236[/tex]
If a package exceeds 45 ounces, an additional charge is incurred. What is the proportion of packages will incur such a charge
This proportion is 1 subtracted by the pvalue of Z when X = 45. So
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{45 - 42}{2.236}[/tex]
[tex]Z = 1.34[/tex]
[tex]Z = 1.34[/tex] has a pvalue of 0.9099
1 - 0.9099 = 0.0901
0.0901 = 9.01% of packages will incur such a charge

The students measured length during a science experiment,they got 12 cm.But the actual measurement was 14.25cm.what was the percent error?
Answer:
Percent error = 15.79%
Step-by-step explanation:
Given the following data;
Experimental value = 12cm
Actual value = 14.25cm
To find the percentage error;
Percent error can be defined as a measure of the extent to which an experimental value differs from the theoretical value.
Mathematically, it is given by this expression;
[tex] Percent \; error = \frac {experimental \;value - actual \; value}{ actual \;value} *100[/tex]
Substituting into the equation, we have;
[tex] Percent \; error = \frac {12 - 14.25}{14.25} *100[/tex]
[tex] Percent \; error = \frac {2.25}{14.25} *100[/tex]
[tex] Percent \; error = 0.1579 *100[/tex]
Percent error = 15.79%

The value of x rounded to the nearest whole number is 920.
What are Percentages?A percentage is a way to describe a part of a whole such as the fraction ¼ can be described as 0.25 which is equal to 25%.
To convert a fraction to a percentage, convert the fraction to decimal form and then multiply by 100 with the '%' symbol.
Given that the number 312.8 is 34% of x.
Thus, we can write,
34% of x = 312.8
(34/100) × x = 312.8
Now, Multiply both the sides of the equation by 100,
(34/100) × x × 100 = 312.8 × 100
Now, Divide both the sides of the equation by 34,
[(34/100) × x × 100] ÷ 34 = (312.8 × 100) ÷ 38
x = (312.8 × 100)/34
x = 920
Therefore, the value of x rounded to the nearest whole number is 920.

Lisa is making ethernet cables for Mrs. Houston in the computer lab. The spool of wire that she is creating the cables from is 40ft long. She creates 5 equal cables and has 12ft remaining. What was the length of each cable? (HOW DID YOU GET YOUR ANSWER PLEASE SHOW ME YOUR WORK!!)
A. 16.6%
B. 50%
C. 20%
D. 5.6FT
E. $29.40
F. $30.40
G. 6.3FT
H. 25%
Answer:
D. 5.6 ft
Step-by-step explanation:
40 ft - 12 ft = 28 ft (You subtract the leftover wire(12 ft) from the total amount(40 ft) so you can see how much wire was used to make the 5 cables. There was 28 ft of wire in total used to create the 5 cables.) 28 ÷ 5 = 5.6 ft (You divide 28 by 5 so that you can see how much wire was used for each cable.)Final Answer: The length of each cable was 5.6 ft or just 5.6 ft.Lillian wants to give 1/3 of a pizza to each of six girls at her party
Answer:
[tex]Fraction = \frac{1}{18}[/tex]
Step-by-step explanation:
Given
[tex]Pizza = \frac{1}{3}[/tex]
[tex]Girls = 6[/tex]
Required [Missing Information]
Determine the fraction each girl gets
To do this, we simply divide the pizza by the number of girls i.e.
[tex]Fraction = \frac{Pizza}{Girls}[/tex]
[tex]Fraction = \frac{1}{3} / 6[/tex]
Change / to *
[tex]Fraction = \frac{1}{3} *\frac{1}{6}[/tex]
[tex]Fraction = \frac{1}{18}[/tex]
Hence, each girl gets 1/18

If m 4 = (3x + 7) , and m 5 = (9x 43) , find m UPS.
Two angles whose sum is 180° are called supplementary angles. The measure of ∠UPS is 151°.
What are supplementary angles?Two angles whose sum is 180° are called supplementary angles. If a straight line is intersected by a line, then there are two angles form on each of the sides of the considered straight line. Those two angles are two pairs of supplementary angles. That means, that if supplementary angles are aligned adjacent to each other, their exterior sides will make a straight line.
Since ∠4 and ∠5 form a line, therefore, the two lines are supplementary to each other. Thus, the sum of the two angles can be written as,
∠4 + ∠5 = 180°
(3x + 7) + (9x - 43) = 180
3x + 7 + 9x - 43 = 180
3x + 9x + 7 - 43 = 180
12x - 36 = 180
12x = 180 + 36
12x = 216
x = 216 / 12
x = 18
Now, the measure of ∠UPT can be written as,
∠UPT = ∠4
∠UPT = 3x + 7
= 3(18) + 7
= 54+7
= 61°
Further, since the ∠UPS is formed of ∠UPT and ∠TPS, therefore, we can write,
∠UPS = ∠UPT + ∠TPS
= 61° + 90°
= 151°
Hence, the measure of ∠UPS is 151°.

what is 5 x 2/9 as a fraction.
Answer:
10/9
Step-by-step explanation:
So first you have to convert 5 to a fraction. 5/1 is equal to 5 so that means that 5/1 can work. 5/1x2/9=10/9 because all you have to do is multiply the numerator with the numerator and the denominator with the denominator.
Hope this helps
Answer:
10/9 (1 1/9
Step-by-step explanation:
That’s the fraction way, so all you simply do is multiply 5 by the numerator (2) then you would put it over the 9, which would make it 10/9. Also if you would like to simplify it but still it be a fraction, it would be 1 1/9.

Robert gets a job with a starting salary of $35,000. He is promised a $2500 raise each
subsequent year. Which of the following numbers represents his salary during his 7th
year of employment?
A. $45,000
B. $47,500
C. $50,000
D. $52,500
Step-by-step explanation:
starting salary = $35,000
raise in 1 year = $2500
raise in 7 year = $17,500
salary on 7th year = $35,000 + $17,500
= $52,500
