A researcher decides to split scores on an exam into quartiles. She determines that a score of 64 is at the 25th percentile, a score of 74 is at the 50th percentile, and a score of 80 is at the 75th percentile. What is the interquartile range (IQR) for these data
Answer: IQR = 16
Step-by-step explanation:
The given data is 25 th percentile is 64, 50th percentile is 74 and 75 th percentile is 80.
percentage : 25 50 75
score : 64 74 80
Median:- The median is obtained by first arranging the data in ascending or descending order and applying the following rule.
If the number of observations is odd, then the median is observation
term
If the number of observations is even, then the median is observation and observations.
given n=3, middle term is '74'
In this given data the median is (M) = 74
Interquartile range IQR = median of upper half-median of lower half
= 80-64
= 16
IQR = 16

Imagine that you are designing a solar car. If you mount solar cells on the underside of the car as well as on the top in direct sunlight, and it takes five times as many cells underneath to generate the same amount of electricity generated by the cells on top, what percentage of the sunlight is reflected back off the pavement?
The percentage of sunlight that is reflected off the pavement, given the proportion of cells required, is 20%.
How to find the percentage of sunlight reflected ?The number of solar cells requred is inversely proportional to the amount of sunlight they receive. In other words the more sunlight a cell receives, the fewer cels are needed to generate a given amount of electricity.
Given that it takes five times as many cells underneath the car to generate the same amount of electricity as the cells on top this imples that the cells underneath are receving one-fifth the amount of sunlight that the cells on top receive.
Since the cells on top are receiving direct sunlght, we can take the amount of sunlight they receive as 100%. Thus, the cells underneath, receiving one-fifth of this amount, are receiving 20% of the sunlight.

What is the y-intercept of =−3−7xy
The y-intercept is (0, -3)
The y-intercept is the point where the line on the graph cuts the y-axis.
To find the y-intercept, we let x equal to zero and solve for y.
y = -3 - 7x (given equation)
Substitute x = 0 in the equation,
y = -3 - 7(0)
y = -3 - 0
y = -3
Thus we can conclude that the y-intercept for the given equation y = -3 - 7x is (0, -3).

The six sides of a number cube are labeled 1,2,3,4,5, and 6. You flip a coin and roll the number of the cube. What us the theoretical probability that the coin lands on heads and u roll the number less then 5.Write your answer a fraction
Answer:
The probability is 1/3
Step-by-step explanation:
At any point in time, the probability that a coin lands on head = 1/2 given that the coin is fair
Rolling a number less than 5;
The numbers are 1,2,3 and 4
The probability of rolling a number less than 5 is 4/6
So we proceed to
multiply both probabilities to get the answer to the question,
we have this as;

The measure of angle APB in the intersecting chords is 10⁰.
What is the measure of angle APB?
The measure of angle APB is calculated by applying intersecting chord theorem which that the angle at tangent is half of the arc angle of the two intersecting chords.
The value of m∠APB is calculated as follows;
m∠APB = ¹/₂ (arc AC - arc AB ) ( exterior intersecting secants)
The value of arc angle AC = 80⁰
The value of arc angle AB = 60⁰
Now substitute and solve for the value of angle APB as follows;
m∠APB = ¹/₂ (80 - 60 )
m∠APB = ¹/₂ ( 20 )
m∠APB = 10⁰

identify the parameters p and n in the following binomial distribution scenario. the probability of winning an arcade game is 0.489 and the probability of losing is 0.511. if you play the arcade game 15 times, we want to know the probability of winning more than 8 times. (consider winning as a success in the binomial distribution.)
Here the parameters, p =0.489 and n=15, and the probability of winning more than 8 times is 0.17946
while you playing an arcade game, there are two possible outcomes: win or lose, which is related to the binomial distribution, such as :
P= \(C_{n,k}\) \(p^{n}\) \(q^{n-k}\)
where C is the combination, p is the probability of success and the q is the complement of the p (q=1-p) .Here we are given that the probability of winning an arcade game is 0.489 and the probability of losing is 0.511. So p= 0.489, since the number of the trial are 15, we need to find the probability for more than 8 times, which means
P(X>8)= P(X=9)+P(X=10)+P(X=11)+P(X=12)+P(X=13)+P(X=14)+P(X=15) P(X>8)=P(X>=8)- P(X=8)

What is sample space?"A sample space is a collection or a set of possible outcomes of a random experiment. The sample space is represented using the symbol, “S”. The subset of possible outcomes of an experiment is called events. A sample space may contain a number of outcomes that depends on the experiment. If it contains a finite number of outcomes, then it is known as discrete or finite sample spaces."
"The samples spaces for a random experiment is written within curly braces “ { } “. There is a difference between the sample space and the events."

Anton want to make 5lb ugar yrup. How much water and how much ugar doe he need for 75% yrup
Anton needs 3.75 lbs of sugar and 1.25 lbs of water to make 5 lbs of 75% sugar syrup.
To make a 75% sugar syrup, Anton will need 75% sugar and 25% water by weight. To find out how much sugar and how much water he needs, we can use the following formulas:
Sugar weight = 5lbs x 75% = 3.75lbs
Water weight = 5lbs x 25% = 1.25lbs
So Anton needs 3.75 lbs of sugar and 1.25 lbs of water to make 5 lbs of 75% sugar syrup.
It's important to note that syrup with 75% sugar content is heavy syrup, it is mostly used for preservation and not as a sweetener.

After solving, the height of the cylinder is 6 meters.
The surface area of a cylinder is 24π m².
The distance around the base of the cylinder is 3π meter.
The diameter of a base of the cylinder is 4 meter.
Now the radius of the cylinder = diameter/2
The radius of the cylinder = 4/2
The radius of the cylinder = 2 meter.
The formula of surface area of cylinder:
S = 2πrh
From the question:
2πrh = 24π

f(x) = (2/9)x - (9/2) for x=9
f (9) = - 5/2 is the output for the given input .
How can you tell whether a function is linear or not?
Looking at a function's graph will reveal if it is linear or not with the greatest ease.When a linear function is plotted on a graph, a straight line is formed. A nonlinear function is curved in some way; it does not form a straight line.f(x)= (2/9)x - (9/2)
Put x = 9 ⇒ (2/9) * 9 - (9/2)
⇒ 2 - 9/2

Rewrite the following equation in slope-intercept form.
y + 9 = – (x + 10)
Write your answer using integers, proper fractions, and improper fractions in simplest form.
The slope-intercept form of the equation can be written as y = -x - 19
Slope - Intercept FormThe slope intercept form of a straight line is one of the most common forms used to represent the equation of a line. The slope intercept formula can be used to find the equation of a line when given the slope of the straight line and the y-intercept( the y-coordinate of the point where the line intersects the y-axis). Equation of line is the equation that is satisfied by each point that lies on that line.
The equation given is y + 9 = -(x + 10)
Rewriting this equation in y = mx + c format;
y + 9 = -(x + 10)
y + 9 = -x - 10
y = -x - 10 - 9
y = -x - 19
