The sizes of cans on a shelf are listed below.
18 oz, 8 oz, 16 oz, 20 oz, 20 oz, 16 oz, 12 oz, 8 oz
What is the interquartile range of this list?
2
6
9
12
Answer:
9
Step-by-step explanation:
The interquartile range of the given list is 11 oz.
What is the interquartile range?An interquartile range is a measure of the difference between the upper and lower quartiles of a dataset.
W can find the values of the upper and lower quartile and median from a box plot.
The middle line is the median and the first line is the lower quartile and the last line is the upper quartile.
The formula used is Upper quartile - Lower quartile.
We have,
To find the interquartile range (IQR), we first need to find the first quartile (Q1) and the third quartile (Q3) of the data.
To do this, we first need to order the data set from smallest to largest:
8 oz, 8 oz, 12 oz, 16 oz, 16 oz, 18 oz, 20 oz, 20 oz
Next, we find the median of the data set. Since there are 8 data points, the median is the average of the two middle values:
Median = (16 oz + 16 oz)/2 = 16 oz
Now we can find Q1 and Q3. 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.
Lower half: 8 oz, 8 oz, 12 oz, 16 oz
Upper half: 16 oz, 18 oz, 20 oz, 20 oz
Q1 = (8 oz + 8 oz)/2 = 8 oz
Q3 = (18 oz + 20 oz)/2 = 19 oz
Finally, we can calculate the IQR as the difference between Q3 and Q1:
IQR = Q3 - Q1 = 19 oz - 8 oz = 11 oz
Therefore,
The interquartile range of the given list is 11 oz.

Find the measure of arc AB. 
Answer:
AB = 3π units
Step-by-step explanation:
The arc length is calculated as
AB = circumference of circle × fraction of circle
= 2πr × [tex]\frac{45}{360}[/tex]
= 2π × 12 × [tex]\frac{1}{8}[/tex]
= 24π × [tex]\frac{1}{8}[/tex]

4. Which graph represents the solution to
-2<3x+1 ?
Hey there!
-2<3x+1
= 3x + 1 < -2
SUBTRACT 1 to BOTH SIDES
3x + 1 - 1 < -2 + 1
CANCEL out: 1 - 1 because that gives you 0
KEEP: -2 + 1 because that helps you solve for x
-2 + 1 = -3
New EQUATION: 3x > -3
DIVIDE 3 to BOTH SIDES
3x/3 > -3/3
CANCEL out: 3/3 because that gives you 1
KEE3 -3/3 because that helps us compare for x
-3/3 = -1
Answer to the equation: x > -1
OVERALL Answer: x > -1; It is an OPENED circle shaded to the right starting at -1 (Option A.)

Answer:
The correct option is - D.
Step-by-step explanation:
To find - Select the correct answer. The parent tangent function is transformed such that its period is halved. Which graph could represent the transformed function?
Solution -
We know that,
The parent tangent function is -
f(x) = tan(x)
Period of Parent function = [tex]\pi[/tex]
Now,
If Period is half,

x^2 - 9x - 10 = 0 = (x - 10)(x + 1) = 0.
Setting each factor equal to zero and then solving for x yields {-1, 10}

a) If twice the son's age in years is added to the father's age, the sum is 70. But twice
the father's age is added to the son's age, the sum is 95, find the present ages of the
father and his son.
Answer:
Son = 15 and father = 40
Step-by-step explanation:
Let, the age of son be x and father be y.
According to the question,
2x + y = 70
or. y = 70 - 2x ..................................(1)
Also,
2y + x = 95
or, 2(70 - 2x) + x = 95 (From 1)
or, 140 - 4x + x = 95
or, 45 = 3x
∴ x = 15
Now,
Substituting value of x in (1)
y = 70 - 30 = 40
∴ The present ages of son and father are 15yrs and 40yrs respectively.
