The interquartile range of the data-set is of 5.5, which means that the middle 50% kindergarten classes has a number of students that differ by at most 5.5.
What are the median and the quartiles of a data-set?The median of the data-set separates the bottom half from the upper half, that is, it is the 50th percentile.The first quartile(Q1) is the median of the first half of the data-set, and is also the 25th percentile.The third quartile(Q3) is the median of the second half of the data-set, and is also the 75th percentile.The interquartile range(IQR) represents the middle 50% of the distribution, and is given by Q3 - Q1.For this problem, the ordered data-set is given by:
18, 18, 18, 20, 21, 22, 23, 23, 24, 24.
There are 10 elements, hence:
The first half is 18, 18, 18, 20, which has median (18 + 18)/2, hence Q1 = 18.The second half is 23, 23, 24, 24, which has median (23 + 24)/2, hence Q3 = 23.5.Then the IQR is:
Q3 - Q1 = 23.5 - 18 = 5.5.
The IQR is of 5.5, which means that the middle 50% kindergarten classes has a number of students that differ by at most 5.5.

A study of a local high school tried to determine the mean amount of money that each student had saved. The study surveyed a random sample of 96 students in the high school and found a mean savings of 4000 dollars with a standard deviation of 500 dollars. Determine a 95% confidence interval for the mean, rounding all values to the nearest whole number.
I don't know sorry I will try and come back If I get it :D
A 95% confidence interval for the average is 4100
What is confidence interval ?The confidence interval formula is used in statistics for describing the amount of uncertainty associated with a sample estimate of a population parameter. It is used to describe the uncertainty associated with a sampling method.
Formula of confidence interval:
If n ≥ 30,
Confidence Interval = m ± [tex]z(\frac{SD}{\sqrt{n} } )[/tex]
where,
n = Number of terms
m = Sample average
SD = Standard Deviation
z = Value corresponding to confidence interval in z table
Table of Confidence interval and Z
CI z
0.70 1.04
0.75 1.15
0.80 1.28
0.85 1.44
0.90 1.645
0.92 1.75
0.95 1.96
0.96 2.05
0.98 2.33
0.99 2.58
According to the question
random sample of student (n) = 96
average savings = 4000 dollars
Standard deviation = 500 dollars
95% confidence interval for the average needed
i.e , z = 1.96
Now, By using Formula of confidence interval:
Confidence Interval = m ± [tex]z(\frac{SD}{\sqrt{n} } )[/tex]
substituting the values
Confidence Interval = 4000 ± [tex]1.96(\frac{500}{\sqrt{96} } )[/tex]
= 4000 ± 100.021
= 4100.21
values to the nearest whole number
Confidence Interval = 4100
Hence, A 95% confidence interval for the average is 4100 .

Step-by-step explanation:
A house was valued at $238,000. Over several years, the value decreased by 16%, giving the house a new value.
(a) Fill in the blank to write the new value in terms of the old value.
Write your answer as a decimal.
New value = 1 x Old value
(1) Use your answer in part (a) to determine the new value.
New value: 0
Answer:
The new value of the house after the 16% decrease would be $199,920.
Step-by-step explanation:
Given that a house was valued at $ 238,000, and over several years, the value decreased by 16%, giving the house a new value, to determine the new value the following calculation must be performed:
238,000 - (238,000 x 0.16) = X
238,000 - 38,080 = X
199.920 = X
Thus, the new value of the house after the 16% decrease would be $ 199,920.

Answer:
y = 6/5x - 24/5
Step-by-step explanation:
The two points we are given are (4, 0) and (9, 6). First, find the slope.
m = 6 - 0/9 - 4 = 6/5
Next, insert the values into the point-slope form formula. I'll use (4, 0) as the coordinates.
y - 0 = 6/5(x - 4)
y = 6/5x - 24/5
One side of a rectangle is three times as long as another. If its area is 363 square centimeters, find its dimensions.
Shorter side:
Longer side:
9514 1404 393
Answer:
11 cm by 33 cm
Step-by-step explanation:
You can solve this problem mentally as follows.
Consider the rectangle as 3 squares, side-by-side. Then the area of each of those squares is 363/3 = 121 cm^2. From your knowledge of the squares of numbers, you know that 121 = 11^2. So, the width of the rectangle is 11 cm, and the length is 3 times that, or 33 cm.
_____
Using variables, we can let w represent the width. Then 3w can represent the length, and the area is ...
A = LW
A = (3w)(w) = 3x^2 = 363
w^2 = 363/3 = 121
w = √121 = 11
3w = 3·11 = 33
The width is 11 cm; the length is 33 cm.
Answer:
Shorter side: 11 cm
Longer side: 33 cm
First, write down what you know:
length=3*width, this can be written as 3w
area=363 sq cm
Now we know the formula for the area of a rectangle= length * width so we can substitute what we know into the formula. It looks like this:
363 (area) = 3w (length) × w (width)
[tex]363=w^2[/tex]
divide both sides by 3 to get: 121 = [tex]w^2[/tex]
take the square root of both sides to get: w=11 (square root of 121 is 11)
Now that we know what the width is, we can substitute that and find the length: 3w = 3 × 11=33
So length (longer side) is 33cm and width (shorter side) is 11cm.
*To check this, plug the numbers into the area formula: Area=33 × 11 = 363 sq cm.

36 irrational or rational and why?
Answer:
Rational
Step-by-step explanation:
First tip with numbers... All whole numbers are rational and all numbers, rational or irrational are real numbers. Rational numbers consist of whole numbers, integers, fractions, and so on... While irrational numbers are numbers that can't be simplified to a basic whole number or fraction like 36.
Pi (π) is an example of an irrational number.

PLEASE ANSWER ASAP FOR BRAINLEST!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
Answer and Step-by-step explanation:
You got the triangle at front, half of 6 is 3, so then you do 4 times 3 divided by 2, which is 6.
There are 4 of those triangles, so 4 times 6 is 24.
Now, we got two rectangles on top. 5 times 12 is 60, and 60 + 60 is 120.
the bottom rectangle is 6 times 12, which is 72.
Now we add.
24 + 120 + 72 is 216
216 [tex]in^2[/tex] is the answer.

Step-by-step explanation:
Given
[tex]g(f(x)) = 3(x + 4)^2 - 5[/tex]
Required
Find g(x) and f(x)
Replace all expression in bracket with x
[tex]g(x) = 3(x)^2 - 5[/tex]
[tex]g(x) = 3x^2 - 5[/tex]
The expression removed from bracket are:
f(x) and x + 4
