Answer:
a. Mean = 81.5
b. Median = 93.5
c. Mode = 98
Step-by-step explanation:
Given the following data;
x = 83, 98, 22, 89, 99, 98
F(x) = 83 + 98 + 22 + 89 + 99 + 98
F(x) = 489
Number of items, n = 6
a. To find the mean;
Mean = F(x)/n
Mean = 489/6
Mean = 81.5
b. To find the median;
Median refers to the middle number of a sorted data. Thus, we would arrange the number in an ascending order and choose the middle number.
x = 22, 83, 89, 98, 98, 99
Middle numbers = 89 and 98
Median = (89 + 98)/2
Median = 187/2
Median = 93.5
c. To find the mode;
Mode is the number which appeared the most in the series.
Mode = 98
The Mean, median, and mode for the following data set are as follows:
Mean is 81.5Median is 93.5Mode is 98.What are the measures of central tendency?The measures of central tendency include the mode, the median, and the mean.
Statistically, a central tendency is a typical value for a probability distribution.
The mode's value appears most often in a set of data values. The median is the middle value of a dataset. The mean represents the average.
Data and Calculations:Data set (in ascending order)
22 + 83 + 89 + 98 + 98 + 99 = 489
Mean = 81.5 (489/6)
Median = 93.5 (89 + 98)
Mode = 98 (occurred twice more than other values)

Dara pinkston Recorded her house and expenses for a month of August mortgage payment was 347.90Insurance $17 Texas $84 electricity $64.40 phone service $33.50 fuel $98.25 water $17.44 in repairs $79.87 .Her monthly take-home pay is 2150 what’s her total money coast?
Answer:
the total monthly cost is $742.36
Step-by-step explanation:
The computation of the total monthly cost is shown below:
= Mortgage payment + insurance + taxes + electricity + phone service + fuel + water + repairs
= $347.90 + $17 + $84 + $64.40 + $33.50 + $98.25 + $17.44 + $79.87
= $742.36
Hence, the total monthly cost is $742.36
12. Nine more than y is twenty one.
Answer:
y+9=21
Step-by-step explanation:
9 more than y equals 21.
Answer
y=12
Step-by-step explanation:
y+9=21 (this would be the formula)
-9 -9 (you want to eliminate 9 from the equation, so subtract it from both sides of the equation)
y=12 (after subtracting 9 from both sides you are left with 12)
Check it
12+9=21 (is this true?)
21=21 (yes it is true, therefore y=12)

coins, 10% are pennies and 38% are dimes. There are 2 more nickels than pennies. How much
money does the bag contain?
Answer:
5 pennies
7 nickels
19 dimes
$2.3
Step-by-step explanation:
first i like to find 1%
50/100=1%
50/100=0.5
then multiply to find %'s
0.5x10=pennies
0.5x10=5
0.5x38=dimes
0.5x38=19
since there are 2 more nickels than pennies there are 7 nickels since there are 5 pennies
then find each value and add
5x.01+7x.05+19x.10
0.05+0.35+1.9=$2.3

Focusing on describing or explaining data versus going beyond immediate data and making inferences is the difference between _______. Group of answer choices central tendency and common tendency mutually exclusive and mutually exhaustive properties descriptive and inferential statistics positive skew and negative skew
Answer:
descriptive and inferential statistics.
Step-by-step explanation:
Science can be defined as a branch of intellectual and practical study which systematically observe a body of fact in relation to the structure and behavior of non-living and living organisms (animals, plants and humans) in the natural world through experiments.
In Statistics, sampling can be defined as a process used to collect or select data (objects, observations, or individuals) from a larger statistical population using specific procedures.
There are various types of sampling used by researchers and these are;
1. Random sampling.
2. Systematic sampling.
3. Stratified sampling.
4. Cluster sampling.
5. Opportunity or convenience sampling.
Focusing on describing or explaining data versus going beyond immediate data and making inferences is the difference between descriptive and inferential statistics because descriptive statistics focuses on describing or explaining data contained in a population or obtained as a sample while inferential statistics is solely based on drawing an inference from a sample or population.
According to survey data, the distribution of arm spans for males is approximately Normal with a mean of 71.4 inches and a standard deviation of 3.1 inches. a. What percentage of men have arm spans between 66 and 76 inches? b. A particular professional basketball player has an arm span of almost 89 inches. Find the z-score for this person's arm span. What percentage of males have an arm span at least as long as this person?
Answer:
a) 89.97% of men have arm spans between 66 and 76 inches.
b) The z-score for this person's arm span is 5.68. 0% of males have an arm span at least as long as this person
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.
Mean of 71.4 inches and a standard deviation of 3.1 inches.
This means that [tex]\mu = 71.4, \sigma = 3.1[/tex]
a. What percentage of men have arm spans between 66 and 76 inches?
The proportion is the pvalue of Z when X = 76 subtracted by the pvalue of Z when X = 66. The percentage is the proportion multiplied by 100.
X = 76
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{76 - 71.4}{3.1}[/tex]
[tex]Z = 1.48[/tex]
[tex]Z = 1.48[/tex] has a pvalue of 0.9306
X = 66
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{66 - 71.4}{3.1}[/tex]
[tex]Z = -1.74[/tex]
[tex]Z = -1.74[/tex] has a pvalue of 0.0409
0.9306 - 0.0409 = 0.8997
0.8997*100% = 89.97%
89.97% of men have arm spans between 66 and 76 inches.
b. A particular professional basketball player has an arm span of almost 89 inches. Find the z-score for this person's arm span. What percentage of males have an arm span at least as long as this person?
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{89 - 71.4}{3.1}[/tex]
[tex]Z = 5.68[/tex]
The z-score for this person's arm span is 5.68.
Z = 5.68 has a pvalue of 1
1 - 1 = 0
0% of males have an arm span at least as long as this person
The percentage of men who have arm spans between 66 and 76 inches is 89.97% and the percentage of males who have an arm span at least as long as this person is 0%.
Given :
According to survey data, the distribution of arm spans for males is approximately Normal with a mean of 71.4 inches and a standard deviation of 3.1 inches.
a) The formula of z-score is given below:
[tex]\rm Z = \dfrac{X-\mu}{\sigma}[/tex]
where [tex]\mu[/tex] is the mean and [tex]\sigma[/tex] is the standard deviation.
When X = 66 the formula of z-score becomes:
[tex]\rm Z = \dfrac{66-71.4}{3.1}[/tex]
Z = -1.74
The p-value regarding the (Z = -1.74) is 0.0409.
When X = 76 the formula of z-score becomes:
[tex]\rm Z = \dfrac{76-71.4}{3.1}[/tex]
Z = 1.48
The p-value regarding the (Z = 1.48) is 0.9306.
Now, the percentage of men who have arm spans between 66 and 76 inches is:
= (0.9306 - 0.0409) [tex]\times[/tex] 100 %
= 89.97%
b) Now, at X = 89 the formula of z-score becomes:
[tex]\rm Z = \dfrac{89-71.4}{3.1}[/tex]
Z = 5.68
The p-value regarding the (Z = 5.68) is 1.
So, the percentage of males who have an arm span at least as long as 89 inches is:
= (1 - 1) [tex]\times[/tex] 100 %
= 0%

Answer:
1. area DEF = 2π cm²
2. arc JK = 2π cm
Step-by-step explanation:
1. The area is given by ...
A = 1/2r²θ . . . . . where r is the radius and θ is the central angle in radians
Your sector has an area of ...
A = (1/2)(3 cm)²(80(π/180)) = (1/2)(9 cm²)(4/9π)
A = 2π cm²
__
2. The length of an arc is ...
s = rθ . . . . . . . where r is the radius and θ is the central angle in radians
s = (5 cm)(72(π/180)) = (5 cm)(2/5π)
s = 2π cm . . . arc length
_____
Additional comment
There are π radians in 180°, so an angle in degrees can be converted to an angle in radians by multiplying by π/180°. (The units of degrees cancel, leaving a pure number. "Radians" have no units.)
