Answer:
His weight is 8 pounds 9 ounces
Step-by-step explanation:
First, you need to know if you are converting from a smaller unit of measurement to a bigger unit of measurement OR if you are converting from a larger unit to a smaller unit.
→ RULE
When converting from smaller units to bigger units of measurement, you need to divide.When converting from larger units to smaller units of measurement, you need to multiply.Ounces are smaller than pounds, so you need to divide.
To convert 137 ounces to pounds, you would divide 137 ounces by 16 ounces, since 1 pound equals 16 ounces.
1 pound = 16 ounces
137 ÷ 16 = 8 R 9 (long division)
The quotient (8) is the number of pounds and the remainder (9) is the number of ounces.
8 R9 → 8 pounds 9 ounces
137oz = 8 pounds 9 ounces
→ Alana's baby bother weighted 8 pounds 9 ounces.
(^ the question asks for an answer in pounds AND ounces)

what is 28.086 as a %?
Answer:
= 2808.6%
Step-by-step explanation:"Percent" means "per 100" or "over 100". So, to convert 28.086 to percent we rewrite 28.086 in terms of "per 100" or over 100.
Multiply 28.086 by 100/100. Since 100/100 = 1, we are only multiplying by 1 and not changing the value of our number.
28.086/1×100/100=2808.6100
2808.6/100 is 2808.6 over 100 and means 2808.6 per 100. 2808.6 "per 100" means 2808.6 "percent" or 2808.6%
Therefore, we have shown that
28.086 = 2808.6%
Simplified Conversion:Multiply by 100 and add the percent sign %
28.086 × 100 becomes 2808.6%
Shortcut Conversion:Move the decimal point 2 places to the right and add the percent sign %
28.086 becomes 2808.6%
Jobs arrive at the server at the rate of 8 jobs per hour. The service takes 3 minutes, on the average. This system is modeled by the Bernoulli single-server queuing process with 5-second frames and capacity limited by 3 jobs. Write the transition probability matrix for the number of jobs in the system at the end of each frame.
Answer:
2249 / 540000
Step-by-step explanation:
Jobs arrival time = 8 jobs per hour
Service takes 3 minutes on average
Frame size = 5 second
capacity of each frame = 3 jobs
Determine the transition probability matrix for number of jobs in system
First step : find probability of job arrival
= 8 / ( 5 * 3600)
= 8 / 18000 = 1 / 2250
next : determine probability of service
= ( 3 * 5 )/ 3600
= 15 / 3600 = 1/240
Finally the transition probability matrix ( p10 )= { 1, 0}
= probability of service(1 - probability of arrival)
= 1/ 240 * ( 1 - 1 / 2250 )
= 1 / 240 * ( 2249 / 2250 )
= 2249 / 540000

Answer:
√29
Step-by-step explanation:
We can call the given points A(3, 4) and B(-2, 6).
The right triangle with segment AB as a hypotenuse can best be drawn along grid lines. Then the vertical leg is the difference of y-coordinates: 6-4 = 2, and the horizontal leg is the difference of x-coordinates: 3 -(-2) = 5.
The Pythagorean theorem tells you the square of the hypotenuse is the sum of the squares of the legs.
AB² = 2² + 5²
AB² = 4 + 25 = 29
Taking the square root, we find the length of the line segment between the points to be ...
AB = √29

Answer:
Volume of beach ball = 4176.2 inch³ (Approx.)
Step-by-step explanation:
Given:
Diameter of beach ball = 20 inches
Find:
Volume of beach ball
Computation:
Radius of beach ball = Diameter / 2
Radius of beach ball = 20 / 2
Radius of beach ball = 10 inches
We know that beach ball is a sphere shape
So,
Volume of beach ball = Volume of sphere
Volume of sphere = [4/3][π][r³]
Volume of beach ball = [4/3][π][r³]
Volume of beach ball = [4/3][22/7][10³]
Volume of beach ball = [1.33][3.14][1,000]
Volume of beach ball = 4176.2 inch³ (Approx.)

A potato chip company produces a large number of potato chip bags each day and wants to investigate whether a new packaging machine will lower the proportion of bags that are damaged. The company selected a random sample of 150 bags from the old machine and found that 15 percent of the bags were damaged, then selected a random sample of 200 bags from the new machine and found that 8 percent were damaged. Let p^O represent the sample proportion of bags packaged on the old machine that are damaged, pˆN represent the sample proportion of bags packaged on the new machine that are damaged, pˆC represent the combined proportion of damaged bags from both machines, and nO and nN represent the respective sample sizes for the old machine and new machine.
Required:
Have the conditions for statistical inference for testing a difference in population proportions been met?
Answer:
The conditions for the approximation have been met
Step-by-step explanation:
Random samples on both cases and
p∧o proportion of bags packaged on the old machine that are damaged
p∧n sample proportion of bags packaged on the new machine that are damaged
p∧c = ( p∧o + p∧n ) / (nO + nN )
p∧o = 15 % p∧o = 0,15 nO = 150
p∧o * nO = 0,15 *150 p∧o * nO = 22,5
p∧n = 8 % p∧n = 0,08 nN = 200
p∧n*nN = 0,08 * 200 p∧n*nN = 16
Both p∧n*nN and p∧o * nO are bigger than 5
Therefore both samples are big enough for the approximation of the binomial distribution to normal distribution

Ricki caught ten fish. The weights of the fish are shown in the line plot below. Each x represents one fish. What is the total weight of all of the fish? A. 48 1/4 oz B. 44 3/4 oz C. 47 3/4oz D. 45 2/4 oz
Answer:
The correct answer is C. 47 3/4 oz.
Step-by-step explanation:
Since Ricki caught ten fish, and the weights of the fish were 3 2/4 oz one of them, 4 1/4 oz three of them, 4 3/4 oz two of them, and 5 2/4 oz four of them To determine their total weight, the following calculation must be performed:
3 2/4 + (4 1/4 x 3) + (4 3/4 x 2) + (5 2/4 x 4) = X
3 2/4 + 12 3/4 + 9 2/4 + 22 = X
46 7/4 = X
47 3/4 = X
Therefore, the total weight of the fish was 47 3/4 oz.

g Annual starting salaries in a certain region of the U. S. for college graduates with an engineering major are normally distributed with mean $39725 and standard deviation $7320. Suppose a school takes a sample of 125 such graduates and records the annual starting salary of each. The probability that the sample mean would be at least $39000 is about
Answer:
The probability that the sample mean would be at least $39000 is of 0.8665 = 86.65%.
Step-by-step explanation:
To solve this question, we need to understand the normal probability distribution and the central limit theorem.
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 z-score 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 p-value, we get the probability that the value of the measure is greater than X.
Central Limit Theorem
The Central Limit Theorem estabilishes that, for a normally distributed random variable X, with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]s = \frac{\sigma}{\sqrt{n}}[/tex].
For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.
Mean $39725 and standard deviation $7320.
This means that [tex]\mu = 39725, \sigma = 7320[/tex]
Sample of 125
This means that [tex]n = 125, s = \frac{7320}{\sqrt{125}}[/tex]
The probability that the sample mean would be at least $39000 is about?
This is 1 subtracted by the pvalue of Z when X = 39000. So
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
By the Central Limit Theorem
[tex]Z = \frac{X - \mu}{s}[/tex]
[tex]Z = \frac{39000 - 39725}{\frac{7320}{\sqrt{125}}}[/tex]
[tex]Z = -1.11[/tex]
[tex]Z = -1.11[/tex] has a pvalue of 0.1335
1 - 0.1335 = 0.8665
The probability that the sample mean would be at least $39000 is of 0.8665 = 86.65%.
