Solution:
The problem is not clear.
But, considering data set is:
18,25,28,33,42
So, if we consider the data set, Interquartile Range is the difference of Quartile3-Quartile1
IQR=Q3-Q1
To find, Q1 and Q3. Let us find the median, or, Q2 first.
Median is the middle term of the data set.
So, Median, Q2=28
Q1 is the median of first half of the data set. That is, 18,25,28
So, Lower Quartile, Q1=25
Q3 is the median of second half of data set. That is, 28, 33,42
So, Upper Quartile, Q3=33
IQR=Q3-Q1
=33-25=8
Answer: IQR=8
If we consider data set: 6,7,8,9
Median, Q2=[tex] \frac{(7+8)}{2}=\frac{15}{2} [/tex]=7.5
Lower Quartile, Q1=6.25
Upper Quartile, Q2=8.75
IQR=Q3-Q1=8.75-6.25=2.5
IQR=2.5

How to calculate the probability of an event?Suppose that there are finite elementary events in the sample space of the considered experiment, and all are equally likely.
Then, suppose we want to find the probability of an event E.
Then, its probability is given as
[tex]P(E) = \dfrac{\text{Number of favorable cases}}{\text{Number of total cases}} = \dfrac{n(E)}{n(S)}[/tex]
where favorable cases are those elementary events who belong to E, and total cases are the size of the sample space.
For this case, we're given that:
Spinner has 11 parts, numbered 1, 2, .... , 11P(result of spin is multiple of 5 or multiple of 2) = To find.Take E = Event of spinner's spin resulting in multiple of 5 or multiple of 2
S = results of Sample
Then, favorable results (in favor of E) are: 2,4,5,6,8,10 (total 6 in count)
All possible results are 1, 2, ... , 11 (total 11 in count)
Thus, we get:
[tex]P(E) = \dfrac{\text{Number of favorable cases}}{\text{Number of total cases}} = \dfrac{6}{11}[/tex]
Thus, the probability that the result is a multiple of 5 and a multiple of 2 is 6/11

In a spinner numbered 1 through 11, there is only one number (10) that is both a multiple of 5 and a multiple of 2. As there are 11 possible outcomes in a single spin, the probability of spinning and landing on 10 is 1/11.
Explanation:The subject of this question is mathematical probability. Given that there is a spinner with 11 equal areas numbered 1 through 11, we are asked to find the probability of landing on a number that is both a multiple of 5 and a multiple of 2 when the spinner is spun once.
Firstly, we identify the numbers which are both multiples of 5 and 2 between 1 and 11. In this case, only one such number exists, which is 10. Hence, there is only one favorable outcome. The total number of outcomes are 11 (as the spinner has 11 equal areas).
Probability is defined as 'number of favorable outcomes' divided by the 'total number of outcomes'. In this case, since there is 1 favorable outcome (i.e. landing on '10') and 11 possible outcomes (any of the numbers 1 to 11), the probability is therefore 1/11.

Emma enjoys flying kites. her red kite has a maximum altitude of 117.46 meters, and her black kite has a maximum altitude of 362.26 feet. one foot is the same as 0.3048 meters. which kite has a higher maximum altitude, and how many feet higher is it?
Answers
[tex]1 ft : 0.3048 m = 362.26 ft : x[/tex]
From which we find
[tex]x=110.42 m[/tex]
This is the maximum altitude (in meters) of the black kite. The problem says that the maximum altitude of the red kite is 117.46 m, therefore the red kite is the one with higher maximum altitude.
2) Let's convert the maximum altitude of the red kite from meters to feet, again by using the proportion:
[tex]1 ft : 0.3048 m = x : 117.46 m[/tex]
From which we find
[tex]x=385.37 ft[/tex]
Therefore, the maximum altitude of the red kite in feet is 385.37 ft.
Answer:
Red kite has maximum altitude with 23.1 feet higher.
Step-by-step explanation:
Given : Emma enjoys flying kites. her red kite has a maximum altitude of 117.46 meters, and her black kite has a maximum altitude of 362.26 feet.
one foot is the same as 0.3048 meters.
To find : Which kite has a higher maximum altitude, and how many feet higher is it?
Solution :
First we have to convert meter into feet.
We have given, 1 feet = 0.3048 meters.
[tex]1 \text{ meter }=\frac{1}{0.3048} \text{ feet}[/tex]
So, red kite has a maximum altitude of 117.46 meters
In feet, red kite has a maximum altitude of
[tex]117.46\text{ meter }=\frac{117.46}{0.3048}=385.36 \text{ feet}[/tex]
Now, Red kite has a maximum altitude of 385.36 feet
Black kite has a maximum altitude of 362.26 feet.
385.36>362.26 feet.
Difference is 385.36-362.26=23.1 ft.
Therefore, Red kite has maximum altitude with 23.1 feet higher.

You want to determine the height of the screen at a drive-in movie theater. You use a cardboard square to line up the top and bottom of the screen structure. The vertical distance from the ground to your eye is 5.7 feet and the horizontal distance from you to the screen is 11 ft. The bottom of the screen is 6 feet from the ground. Approximate the height of the screen to the nearest tenth.
The height of the screen is about_______ feet
Answers
The height of the drive-in movie theater screen can be determined using proportions and similar triangles. The total height of the screen is found to be 11.7 feet.
Explanation:To find the height of the screen, you'll need to use similar triangles, as the triangle formed by your line of sight to the top and bottom of the screen is similar to the triangle formed by the screen and the ground. The proportion of the vertical distance from your eye to the ground and the horizontal distance from you to the screen is equal to the proportion of the height of the screen and the horizontal distance from you to the screen. Hence, you can calculate the height of the screen using a cross-multiplication.
So, we have the equation: 5.7/11 = h/11, where h is the height of the screen from your eye level. Solving this gives us h=5.7 feet. Thus, the total height of the screen is the height from the ground to your eye level plus the height of the screen from your eye level. So, the total height = 5.7 feet + 6 feet = 11.7 feet.

In a study of 38% of adults questioned reported that their health was excellent. a researcher wishes to study the health of people living close to a nuclear power plant. find the probability that when 11 adults are randomly selected, at most 3 are in excellent health
Answers
The probability that when 12 adults are randomly selected, 3 or fewer are in excellent health is 0.947.
To find the probability that when 12 adults are randomly selected, 3 or fewer are in excellent health, we can use the binomial distribution formula.
The formula for the probability of getting exactly k successes in n trials, with a probability of success p, is:
P(X = k) = (n choose k) * (p^k) * ((1-p)^(n-k))
In this case, n = 12, k = 3, and p = 0.38 (as 38% of adults reported excellent health).
So, the probability that 3 or fewer adults are in excellent health can be calculated as follows:
P(X <= 3) = P(X = 0) + P(X = 1) + P(X = 2) + P(X = 3)
Let's calculate each term:
P(X = 0) = (12 choose 0) * (0.38^0) * (0.62^12) = 0.190P(X = 1) = (12 choose 1) * (0.38^1) * (0.62^11) = 0.342P(X = 2) = (12 choose 2) * (0.38^2) * (0.62^10) = 0.269P(X = 3) = (12 choose 3) * (0.38^3) * (0.62^9) = 0.146Adding up these probabilities:
P(X <= 3) = 0.190 + 0.342 + 0.269 + 0.146 = 0.947
Rounded to three decimal places, the probability that when 12 adults are randomly selected, 3 or fewer are in excellent health is 0.947.
The probable question may be:
In a study, 38% of adults questioned reported that their health was excellent. A researcher wishes to study the health of people living close to a nuclear power plant. Among 12 adults randomly selected from this area, only 3 reported that their health was excellent. Find the probability that when 12 adults are randomly selected, 3 or fewer are in excellent health.

Isabel deposits $6,000 into an account that earns 1.5% interest compounded monthly. Assuming no more deposits and no withdrawals are made, how much money is in the account after 4 years? Compound interest formula:mc002-1.jpg t = years since initial deposit n = number of times compounded per year r = annual interest rate (as a decimal) P = initial (principal) investment V(t) = value of investment after t years
Answers
After 4 years, with an initial deposit of $6,000 at a 1.5% annual interest rate compounded monthly, Isabel will have approximately $6,370.07 in her account.
Calculating Compound Interest
To calculate the amount of money Isabel will have in her account after 4 years with an initial deposit of $6,000 at an annual interest rate of 1.5% compounded monthly, we can use the compound interest formula:
V(t) = P(1 + r/n)nt
P = principal amount (initial investment) = $6,000
r = annual interest rate (as a decimal) = 0.015
n = number of times the interest is compounded per year = 12
t = number of years the money is invested or borrowed for = 4
Substituting these values into the formula, we get:
V(4) = $6,000(1 + 0.015/12)12(4)
This simplifies to:
V(4) = $6,000(1 + 0.00125)48
Calculating the value inside the parentheses first:
1 + 0.00125 = 1.00125
Then raising it to the 48th power gives us:
1.0012548 ≈ 1.061678
Multiplying this by the principal:
V(4) ≈ $6,000 × 1.061678 ≈ $6,370.07
After 4 years, Isabel's account will have approximately $6,370.07.
