Answers
Answer:
Step-by-step explanation:
A
For the considered case, the weight 6 pound 1 ounce will be taken as : Option C: Lower quartile.
What are quartiles?When we get data which can be compared relatively with each other, for finding quartiles, we arrange them in ascending or descending order.
Quartiles are then selected as 3 points such that they create four groups in the data, each groups approximately possessing 25% of the data.
Lower quartile, also called first quartile has approx 25% in its left partition, and on its right lies approx 75% of the data.
Similarly, second quartile (also called median) is approximately in mid of the data.
Third quartile (also called upper quartile) has approx 75% in its left partition, and on its right lies approx 25% of the data.
Left to right is said in assumption that data was arranged increasingly from left to right
For this case, it is said that 25% of the class weighted less than 6 pounds 1 ounce. That means it is first quartile or say lower quartile.
Thus, for the considered case, the weight 6 pound 1 ounce will be taken as : Option C: Lower quartile.

The following table represents the highest educational attainment of all adult residents in a certain town. If a resident who is 30-49 years old is chosen at random, what is the probability that they have completed a bachelor's degree and no more? Round your answer to the nearest thousandth.
Answers
Answer:
If a resident who is 30-49 years old is chosen at random, the probability that they have completed a bachelor's degree and no more is 29.13%.
Step-by-step explanation:
Taking into account the educational table provided, if a resident who is 30-49 years old is chosen at random, to determine what is the probability that they have completed a bachelor's degree and no more the following calculation must be performed:
30-39 Bachelor's degree = 1576
40-49 Bachelor's degree = 443
30-39 Total = 4062
40-49 Total = 2869
4062 + 2869 = 100
1576 + 443 = X
6931 = 100
2019 = X
2019 x 100/6931 = X
201900/6931 = X
29,129 = X
Therefore, if a resident who is 30-49 years old is chosen at random, the probability that they have completed a bachelor's degree and no more is 29.13%.

Answers
9514 1404 393
Answer:
8√2 units
Step-by-step explanation:
The distance formula is useful.
d = √((x2 -x1)² +(y2 -y1)²)
d = √((10 -2)² +(5 -13)²) = √(64 +64)
d = 8√2
The length of AB is 8√2 units.

In 2002, there were 450 households in the city of Klean that recycled. Each year since 2002, the number of
households that recycle has grown by 8%. Write a function to represent the number of households
in Klean that recycle x years since 2002.
Answers
Answer:
450 x 1.08 ^ X = N
Step-by-step explanation:
Since in 2002, there were 450 households in the city of Klean that recycled, and each year since 2002, the number of households that recycle has grown by 8%, to write a function to represent the number of households in Klean that recycle X years since 2002 the following mathematical reasoning should be raised:
450 (initial number) x 1.08 (8% is added to the initial number) ^ X (years) = Number of households that recycle
450 x 1.08 ^ X = N
Thus, for example, if said number were calculated in 2007, that is, 5 years after 2002, the equation would apply as follows:
450 x 1.08 ^ 5 = N
450 x 1.4693 = N
661.20 = N

Answers
Answer:
All triangles add up to 180 degrees so...
180 - 43 - 59 = 78 degrees.
So x - 78 degrees.
x and y are supplementary angles so...
180 - 78 = 102.
So y = 102.
180 - 102 - 49 = 29 degrees
So z = 29 degrees

so your starting value (10) is not going to have the x by it. instead he is feeding his dog so it will be subtracted from.
x is the number of days he can feed his dog. this will be mulitplied with something.
0.5 is how much he feeds his dog each day. this will be times the number of days or x.

A jar contains 10 red marbles 18 blue marbles and 12 white marbles. Which multiplication will halo you find the sorted probability of picking a red marble, replacing it, then picking a blue marble?

Answer:
[tex]\frac{9}{80}[/tex]
Step-by-step explanation:
So there is 40marbles in total
The probability of picking a red marble first is [tex]\frac{10}{40}[/tex] because there is 10 red marbles out of 40 total marbles
Then you replace it and I'm going to assume that you put the red marble back.
Then you would still have 40 marbles and the probability of picking a blue one is [tex]\frac{18}{40}[/tex] because there is 18 blue marbles.
Then you multiply [tex]\frac{10}{40}[/tex] and [tex]\frac{18}{40}[/tex] and that is [tex]\frac{9}{80}[/tex]

Morgan bought a sofa for $216.00. The finance charge was $25 and she paid for it over 15 months.

Round the answer to the nearest tenth.

Answers
Answer:
9.3%
Step-by-step explanation:
Morgan's approximate APR is approximately 1.0%.
What is an expression?An expression contains one or more terms with addition, subtraction, multiplication, and division.
We always combine the like terms in an expression when we simplify.
We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.
Example:
1 + 3x + 4y = 7 is an expression.com
3 + 4 is an expression.
2 x 4 + 6 x 7 – 9 is an expression.
33 + 77 – 88 is an expression.
We have,
Using the given formula:
Approximate APR = (Finance Charge ÷ Months) x 12 / Amount Financed
We know that the amount financed is the total cost of the sofa minus the finance charge, which is:
Amount Financed = $216.00 - $25.00 = $191.00
We also know that the finance charge was $25.00 and she paid for it over 15 months, so:
Finance Charge ÷ Months
= $25.00 ÷ 15
= $1.67
The approximate APR is:
Approximate APR = ($1.67 x 12) ÷ $191.00 = 0.1393
Rounding this to the nearest tenth gives us 0.1, which is equivalent to 1.0% as the nearest percentage.
Therefore,
Morgan's approximate APR is approximately 1.0%.

With individual lines at its various windows, a post office finds that the standard deviation for normally distributed waiting times for customers on Friday afternoon is 7.2 minutes. To test this claim, the post office experiments with a single, main waiting line and finds that for a random sample of 25 customers, the waiting times for customers have a standard deviation of 3.5 minutes. a) With a significance level of 5 percent, conduct an appropriate test on the claim. (State your null hypothesis, test statistic, critical value, decision rule, conclusion) (15 points) b) What is the 95% confidence interval for the population variance
Answers
Answer:
H0 : σ²= 7.2²
H1 : σ² < 7.2
We can conclude that the mean waiting time of customers vary less, Than 7.2 minutes.
Step-by-step explanation:
H0 : σ²= 7.2²
H1 : σ² < 7.2²
The test statistic :
X² = [(n - 1)*s² ÷ σ²]
s² = 3.5
n = sample size = 25. ; s²
X² = [(25 -1)*3.5² ÷ 7.2²
X² = (24 * 3.5^2) / 7.2^2
X² = 5.67
Pvalue from Chisquare statistic :
P(X² < 5.67) = 0.000042
Pvalue < α ; we reject the Null.
Hence, we can conclude that the mean waiting time of customers vary less, Than 7.2 minutes.
