Answer:
12.8
Step-by-step explanation:
Theorem: The median of a trapezoid is parallel to each base and the length of the median equals one-half the sum of the lengths of the two bases.
OB = (1/2)(AT + KN)
9.12 = (1/2)(5.44+ KN)
Multiply both sides by 2
18.24 = 5.44 + KN
Subtract 5.44 from both sides
12.8 = KN
If OB is the median. Then the measure of the length KN of the trapezoid will be 12.8 units.
What is Geometry?It deals with the size of geometry, region, and density of the different forms both 2D and 3D.
Using a trapezoid tank with median OB.
Then the indicated base/median length will be
If OB = 9.12 and AT = 5.44.
Then the measure of the length KN of the trapezoid will be
OB = (AT + KN)/2
9.12 = (5.44 + KN)/2
18.24 = 5.44 + KN
KN = 12.8
Thus, the measure of the length KN of the trapezoid will be 12.8 units.

Convert 3 qt/min to gallons per hour.
45 gal/h
12 gal/h
180 gal/h
4.5 gal/h
Given:
3 qt/min
To find:
The conversion of 3 qt/min to gallons per hour.
Solution:
We know that,
1 quart = 0.25 gallons
60 minutes = 1 hour
1 minute = [tex]\dfrac{1}{60}[/tex] hour
Using these conversions, we get
[tex]3 \dfrac{qt}{min}=\dfrac{3\times 0.25}{\dfrac{1}{60}}\ \dfrac{gal}{h}[/tex]
[tex]3 \dfrac{qt}{min}=3\times 60\times 0.25\ \dfrac{gal}{h}[/tex]
[tex]3\ qt/min=45\ gal/h[/tex]
Therefore, the correct option is A.
Mario is practicing ice hockey. He usually makes 7 out of 12 shots. What is the probability that mario will NOT make either of his next 2 shots?
Answer:
the probability is 25/144 or about 0.174
Step-by-step explanation:
his chance of not getting the shot is 5/12, so multiply 5/12×5/12 to get the chance of him missing both.
Mario usually makes 7 out of 12 shots, the probability that mario will NOT make either of his next 2 shots is 25/144
To solve the problem, let us define probability
What is probability?This is the likelihood of an event. Probability is given mathematically as P(event) = no of required outcomes/total number of outcomes
Probability that Mario makes no shot.Since Mario makes 7 out of 12 shots, the probability that he makes a shot is P(shot) = 7/12. The probability that he makes no shot is
P(no shot) = 1 - P(shot)
= 1 - 7/12
= 5/12
Probability that mario will NOT make either of his next 2 shotsSince Mario's shots are independent events, the probability of his first shot does not affect that of the second. So, the probability that Mario will not make either ofhis next 2 shots is
P(no 2 shot) = P(no first shot) × P(no second shot)
= P(no shot) × P(no shot)
= 5/12 × 5/12
= 25/144
So, since Mario is practicing ice hockey and usually makes 7 out of 12 shots, the probability that mario will NOT make either of his next 2 shots is 25/144

Park rangers in Yosemite estimated the number of racoons in one hiking area. The rangers tagged 15 racoons in the hiking area. The following week they captured 40 racoons. If the park rangers estimated there were 75 in the area, how many of the captured racoons were tagged.
Answer:
8
Step-by-step explanation:
15 of 75 estimated raccoons in the area were tagged. So think of this as a ratio, 15:75.
Divide 75 by the 40 racoons that were captured and you get 1.87500. 75 divided by 1.87500 is the 40 raccoons captured. So 15 divided by the same amount is the number of raccoons with tags. Divide 15 by 1.87500 to find the missing value, which is 8.

Snow Crest is 11,508.21 feet higher than Mt. Wilson. Write and solve an equation to find the elevation of Mt. Wilson. Let x represent the elevation of Mt. Wilson. The equation to find the elevation of Mt. Wilson is ____-x=_______. The elevation of Mt. Wilson is _______ feet.
Answer:
16642.1 feets
Step-by-step explanation:
Given :
Elevation of Mt. Wilson = x
If the elevation of snow crest = y
Snow crest = 11,508.21 feet higher than Mt. Wilson
Hence, y = 11,508.21 + x
The elevation of Mt. Wilson, x = y - 11,508.21 feets
From the table, elevation of Snow crest = 28,150.31 feets = y
Hence, The elevation of Mt. Wilson, x = y - 11,508.21 feets
x = 28,150.31 - 11,508.21
x = 16642.1 feets

Examine the following data set.
{15, 45, 20, 40, 55, 60, 25, 35, 45, 50, 30}
Which piece of data from the data set is an outlier, if there is one?
A) 15
B) 40
C) 60
D) There are no outliers.
The piece of data from the data set is an outlier, if there is one is that there are no outliers. The correct option is D.
What is interquartile range?The interquartile range is a measure of statistical dispersion, or the spread of data, in descriptive statistics.
To identify outliers, we first need to calculate the median and the interquartile range (IQR) of the data set.
The median is the middle value of the data set when it is arranged in order. If there is an even number of values, the median is the average of the two middle values.
First, we arrange the data set in order:
{15, 20, 25, 30, 35, 40, 45, 45, 50, 55, 60}
The median is the middle value, which is 40.
Next, we calculate the IQR, which is the difference between the third quartile (Q3) and the first quartile (Q1) of the data set.
Q1 is the median of the lower half of the data set, and Q3 is the median of the upper half of the data set. To calculate Q1 and Q3, we first split the data set into two halves:
Lower half: {15, 20, 25, 30, 35}
Upper half: {40, 45, 45, 50, 55, 60}
Q1 is the median of the lower half, which is 25. Q3 is the median of the upper half, which is 50.
So, the IQR is:
IQR = Q3 - Q1 = 50 - 25 = 25
To identify outliers, we use the following rule: any value that is less than Q1 - 1.5 x IQR or greater than Q3 + 1.5 x IQR is considered an outlier.
Q1 - 1.5 x IQR = 25 - 1.5 x 25 = -12.5
Q3 + 1.5 x IQR = 50 + 1.5 x 25 = 87.5
We see that none of the values in the data set are less than -12.5 or greater than 87.5. Therefore, there are no outliers in this data set.
Thus, the answer is D) There are no outliers.
