To answer this question we need to understand the difference between discrete and continous data:
• Discrete data can only take certain values along some interval.
,• Continuous data can take any value along some interval.
In this case we know that there will always be a integer number of people in the meeting, that is, we can only have certain values (we can't have 6.5 people in a meeting).
Therefore, this is a discrete data set.

In a bag of Jolly Ranchers, the ratio of blue to red is 3 to 4. If I have a TOTAL of 56 Jolly Ranchers, how many of them are blue?
Answer:
24
Step-by-step explanation:
If ratio of blue to red is 3:4 or in fraction terms 3/4 then the ratio of blue to all Jolly ranchers = 3/(3+4) = 3/7
Since there are a total of 56, the number of blue ones = 56 x 3/7 = 24
Answer:
24
Step-by-step explanation:
Based on the given conditions, formulate: 56 x 3 divided by (3 + 4)
Calculate the product or quotient: 168/3+4
Calculate the sum or difference:168/7
Cross out the common factor:24

What is the solution to this system of equations?X+ 2y = 4| 2x-2y = 5(3.-5)(3.)no solutioninfinitely many solutions
The given system of equation :
x +2y =4
2x -2y =5
On adding both equation we get
x+2y+2x-2y=4+5
3x=9
x=3
So, for y, substitute x=3
x+2y=4
3+2y=4
2y=4-3
2y=1
y=1/2
The solutions is (3,1/2)
The system of linear equation have infintely many solution if they are coincidient, i.e. slope are equal
The given expression :
x+2y =4
2y=4-x
y=(4-x)/2
y = 2-x/2
So slope is (-1/2)
The second equation : 2x-2y=5
2y=2x-5
y=(2x-5)/2
y=x-

if one face of a cubr has a area of 6.75 square inches, what is the surface of the entire cube.
The surface area of the entire cube is 40.5 square inches
Here, we want to get the surface area of a cube given the measure of the area of one of the faces
Looking at the net of a cube, we can identify six identical and equal-dimension faces
So to get the total surface area of the cube, we have to multiply the surface area of one of the faces by 6
Mathematically, that would be;
[tex]6.75\text{ }\times\text{ 6 = 40.5}[/tex]

Assume that adults have IQ scores that are normally distributed with a mean of μ=100 and a standard deviation σ=20. Find the probability that a randomly selected adult has an IQ less than 128.
The probability that the IQ is less than 128 is 0.91924
How to determine the probability?The given parameters about the distribution are
Mean value of the set of data, μ = 100Standard deviation value of the set of data σ = 20IQ value, x = 128The z-score of the data value is calculated as
z = (x - μ)/σ
Substitute the given parameters in the above equation
z = (128 - 100)/20
Evaluate
z = 1.4
The probability that the IQ is less than 128 is then calculated as:
P(x < 128) = P(z < 1.4)
From the z table of probabilities, we have;
P(x < 128) = 0.91924
Hence, the probability is 0.91924

is this relation a function ? yes or noif no , identify two ordered pairs as proof.
A relation is said to be a function when each input value is related to only one output.
It can also be said that a function is a relation that has only output for any unique input.
In a function, each x-value is related to only one output.
From the relation given here, we have a straight-line graph. Here, each x-value is related to only one y-value.
Since each x-value is related to only one y-value, this relation is a function.
ANSWER:
Yes, this relation is function.
Two owners of a cattle ranch, Robert and Val, want to find the average weight for the ranch’s 200 cows. Instead of weighing all of the cows:
o Robert weighs 25 cows and gets an average weight of 1,550 pounds (stdev = 50)
o Val weighs 100 cows and gets an average weight of 1,380 pounds (stdev = 50)
What is Val’s margin of error, rounded to the nearest whole number? (The formula is 1.96 (std dev) /
If the average weight calculated by Val is 1380 pounds with standard deviation 50 of 100 cows, then Val's margin of error will be 9.80.
Given that average weight found by Val is 1380 pounds with standard deviation 50 of 100 cows.
We are required to find the margin of error of Val's data.
Margin of error is the difference between the actual data and the calculated data.
Margin of error=1.96*σ/[tex]\sqrt{n}[/tex]
In our case σ=50 and n is 100.
Margin of error=1.96*50/[tex]\sqrt{100}[/tex]
=1.96*50/10
=1.96*5
=9.80
Hence if the average weight calculated by Val is 1380 pounds with standard deviation 50 of 100 cows, then Val's margin of error will be 9.80.
