The median and interquartile range are often preferred measures of center and variation when a data set contains outliers because they are robust to outliers.
What is interquartile range?The interquartile range (IQR) is a measure of data set variability or spread. It is the difference between a distribution's third and first quartiles (Q3), and it represents the range of the middle 50% of the data.
When a data set contains outliers, the median and interquartile range are often preferred measures of center and variation because they are robust to outliers.
Outliers are extreme values that are far outside the range of the remaining data points and can have a significant impact on measures of center and variation such as the mean and standard deviation.
Thus, when there are outliers in a data set, using the median and IQR as measures of center and variation, respectively, can provide a more accurate representation of the data set's central tendency and variability than using the mean and standard deviation, which are more sensitive to outliers.

Suppose that you know that angle t and angle s are supplementary, and that the measure of angle t = 3 times the measure of angle s.
How can you find the measure of angle t ?
Answer: 135 degrees
Step-by-step explanation:
Supplementary angles are those angles that sum up to 180 degrees. For example, angle 130° and angle 50° are supplementary angles because the sum of 130° and 50° is equal to 180°.
Using that, you know that angles t and s are equal to 180 degrees. You also know that angle t is 3 times the measure of angle s.
Therefore, we can create this equation.
3s + s = 180
4s= 180
s = 45
Angle s is 45 degrees.
180 - 45 = 135
Angle t is 135 degrees.

Step-by-step explanation:
The x shouldn't change. If this isn't correct, I apologize. But I'm sure I calculated this right.
The coordinates of the figure after a translation of 5 units up is U' ( -3 , 1 ) , M' ( -1 , 4 ) and L' ( -2 , 0 )
The coordinates of the figure after a translation of 3 units up is R' ( -4 , 0 ) , D' ( -4 , 4 ) , L' ( 0 , 3 ) and F' ( 0 , 0 )
What is Translation?A translation moves a shape up, down, or from side to side, but it has no effect on its appearance. A transformation is an example of translation. A transformation is a method of changing a shape's size or position. Every point in the shape is translated in the same direction by the same amount.
A translation in the coordinate plane moves every point on a figure a given distance in a given direction. The position of any point (x, y) on the figure changes to (x + a, y + b), where a and b are real numbers.
Given data ,
Let the translated figure be represented as A
Now , the coordinates of the figure are
a)
The coordinates of the figure are U ( -3 , -4 ) , M ( -1 , -1 ) and L ( -2 , -5 )
And , when the translation is up , the y coordinate increases by d units
The coordinates of the figure after a translation of 5 units up is U' ( -3 , 1 ) , M' ( -1 , 4 ) and L' ( -2 , 0 )
b)
The coordinates of the figure are R ( -4 , -3 ) , D ( -4 , 0 ) and L ( 0 , 0 ) and F ( 0 , -3 )
And , when the translation is up , the y coordinate increases by d units
The coordinates of the figure after a translation of 3 units up is R' ( -4 , 0 ) , D' ( -4 , 3 ) , L' ( 0 , 3 ) and F' ( 0 , 0 )
Hence , the translation is solved

Step-by-step explanation:
SolutionThe solution is in the attached photo, do take note to solve this question, angles properties must be used.
Answer:
x=48°
Step-by-step explanation:
We can see the line at the top. 52°+y+59°=180° because these angles are supplementary angles. We can solve this problem:
52°+y+59°=180°
y=180-52-59
y=180-111
y=80-11
y=69°
because the angles in a triangle add up to 180°, y+63°+x=180°, or
69°+63°+x=180°
We can solve it from here:
69+63+x=180
120+12+x=180
132+x=180
x=180-132
x=80-32
x=48°

Find the percent change to the nearest whole percent
Answer:
40.63% to the nearest whole percent is 41
Step-by-step explanation:
(45 - 32) / 32) * 100 = 40.63 %
To round 40.63 to the nearest whole number consider the tenths’ value of 40.63, which is 6 and equal to or more than 5. Therefore, we have to round up: the whole number part of 40.63, 40, increases by 1 to 41, and the decimal point and all digits (.63) are removed...
40.63 rounded to the nearest whole number = 41

The sum the age of a boy and his sister is 32 years. If the boy is 6 years older than his sister, how old is his sister?
TYVM!! :)
Answer:
The sister is 13 years old.
Step-by-step explanation:
Let the boy's age = b.
Let the sister's age = s.
b + s = 32
b = s + 6
s + 6 + s = 32
b = s + 6
2s + 6 = 32
b = s + 6
2s = 26
b = s + 6
s = 13
b = 13 + 6
s = 13
b = 19
Answer: The sister is 13 years old.

It takes 10 mins to fill a bath with just the hot tap and 15 minutes to fill it just with the cold tap.
How long wikll it take to fill the bath if you run both taps at once?
Please give a equation or the steps of solving, thanks a lot!
===========================================================
Explanation:
Let's say the tub is 30 gallons. I'm picking this number because it's the LCM of 10 and 15. Picking the LCM means that later division operations result in a whole number.
The hot tap takes 10 minutes to fill the tub. Its rate is 30/10 = 3 gallons per minute.
Rate = (amount done)/(time)
The cold tap works at a rate of 30/15 = 2 gallons per minute.
When both taps are running at the same time, they combine to a total rate of 3+2 = 5 gallons per minute. Therefore, it will take 30/5 = 6 minutes if both taps are opened.
Time = (amount done)/(rate)
-------------------------
Another approach:
The hot water tap takes 10 minutes to do 1 job. That "1 job" refers to "fill the bathtub". The unit rate here is 1/10 of a job per minute.
Meanwhile, the cold tap has a unit rate of 1/15 of a job per minute.
The combined rate is 1/10 + 1/15 = 3/30+2/30 = 5/30 = 1/6 of a job per minute.
x = number of minutes it takes to fill the bathtub if both taps are going at once.
We can say:
(unit rate)*(time) = amount done
(1/6 of a job per min)*(x minutes) = 1 job
(1/6)x = 1
x = 6 minutes is the final answer
-------------------------
Another approach:
The template for problems like this is:
1/A + 1/B = 1/C
where
A = amount of time for the hot tap water (working alone)B = amount of time for the cold tap water (working alone)C = amount of time if the two taps work togetherWe end up with the equation
1/10 + 1/15 = 1/x
This can be rearranged into
(1/10+1/15)x = 1
and also rearrange into
(1/6)x = 1
Follow the steps mentioned earlier to end up with 6 minutes as the final answer
You flip a coin and draw a marble at random from a bag containing two purple marbles and one white marble The number of possible outcomes in the sample space is
Answer:
6 possible outcomes
Step-by-step explanation:
Given:
Flip a coin
Draw a marble at random from a bag containing two purple marbles and one white marble
To Find:
The possible outcomes = ?
Solution:
By Flipping a coin, we have two outcomes, either head or tail
For each of these outcomes we will either tale any one of the balls from the bag
So possible outcomes will be
Head - purple ball
head -purple ball
Head -white ball
Tail - purple ball
Tail -purple ball
Tail -white ball
So there are 6 possible outcomes.
When given a set of cards lying face down that spell M, A, T, H, F, A, N, determine the probability of randomly drawing a consonant.
six halves
six sevenths
five sevenths
two sevenths
Answer: five sevenths
Step-by-step explanation:
To determine the probability of randomly drawing a consonant from the set of cards, we first need to identify the consonants in the given letters: M, A, T, H, F, A, N.
From this set of letters, the consonants are M, T, H, F, and N. There are 5 consonants out of a total of 7 letters.
To calculate the probability, we divide the number of favorable outcomes (drawing a consonant) by the total number of possible outcomes (drawing any letter).
The probability of randomly drawing a consonant is:
Number of favorable outcomes: 5 consonants
Total number of possible outcomes: 7 letters
Therefore, the probability of randomly drawing a consonant is 5/7.
Expressing it as a fraction, the probability is five sevenths.
Therefore, the correct answer is five sevenths.

At a school carnival, the diameter of the mat of a trampoline is 16 feet and the diameter of its metal frame is 18 feet. What is the length, in feet, of the metal frame that surrounds the trampoline? Use 3.14 for π and round your answer to the nearest tenth.
a
50.2 feet
b
56.5 feet
c
100.5 feet
d
113.0 feet
The length of the metal frame that surrounds the trampoline can be calculated by subtracting the diameter of the mat from the diameter of the metal frame and then multiplying by π.
The diameter of the mat is 16 feet and the diameter of the metal frame is 18 feet, so the difference is 18 - 16 = 2 feet.
The length of the metal frame can be calculated as follows:
Length = π * (difference in diameter) = 3.14 * 2 feet = 6.28 feet
So, the length of the metal frame is 6.28 feet, which is closest to option a, 50.2 feet. The answer is therefore a.
The average grain of salt is 0. 0003 meters wide. Rhinovirus, which causes the common cold, is 0. 00000003 meters wide. How many times wider is a grain of salt than Rhinovirus? Choose the correct answer. A. 1 × 102 times B. 1 × 103 times C. 1 × 104 times D. 1 × 105 times
Number of times a grain of salt is wider than Rhinovirus
= width of average grain of salt / width of rhinovirus
=0.0003 / 0.00000003
=1 × 10^4
Hence, the number of times a grain of salt is wider than Rhinovirus is 10,000 times.

What is a proportional relationship?A proportional relationship is defined as follows:
y = kx.
In which k is the constant of proportionality.
The constant for a pair (x,y) is given as follows:
k = y/x.
When x = 5/6, y = 2, hence the constant is given as follows:
k = 2/(5/6)
k = 12/5
k = 2.4.
When x = 25/6, y = 10, hence the constant is given as follows:
k = 10/(25/6)
k = 60/25
k = 2.4.
When x = 125/6, y = 50, hence the constant is given as follows:
k = 50/(125/6)
k = 300/125
k = 2.4.
Same constant, hence the table in fact represents a proportional relationship.
