The given data is qualitative in nature because they do not measure or count anything.
According to the question,
We have the following information:
The blood groups are A, B, AB and O.
Now, we have to find whether this data is qualitative or quantitative in nature.
First, we will first find the definitions of qualitative data and quantitative data. Qualitative data means that the data describes the types, names, symbols or the nature of the objects being studies. It is often the nature of observation that is described in these types of data. For example, if one is studying endangered species then the reasons for their decline is qualitative data.
Quantitative data often gives us the numbers or the count of the object.
Now, in this case, we are not given that there are 4 different blood groups. Instead, we are given the types of blood groups.
So, this is qualitative in nature.
Hence, the correct option is A.

At a basketball game, 28% were supporting the visiting team. If total
number of people attending the game was 1100, how many people
were supporters of the home team?
Answer: 792 supporters
Step-by-step explanation:
Change 28% to a decimal
28%=0.28
Find the product of 0.28 and 1100
0.28x1100=308
Subtract 1100 and 308 to find the supporters of the home team

What are the coordinates of Y if (5, 12) is 1/3 of the way from X to Y?
Answer:
Step-by-step explanation:
The coordinates of point Y are (9 , 12)
Step-by-step explanation:
* Lets explain how to solve the problem
- If point (a , b) divides a line whose end points are (c , d) and (e , f) at
ratio p : q from the point (c , d), then
and
∵ Segment XY has one endpoint at X (0 , 0)
∵ Point (3 , 4) is 1/3 of the way from X to Y
∴ Point (3 , 4) divides the segment XY, where the distance from X
to the point (3 , 4) is 1 part and from point (3 , 4) to Y is 2 parts
∴ Point (3 , 4) divides segment XY to the ratio 1 : 2 from X
- Let point (a , b) is (3 , 4)
- Let point (c , d) is X (0 , 0)
- Let point (e , f) is Y
- Let p : q = 1 : 2
* Lets find e and f
∵
∴
∴
- Multiply both sides by 3
∴ 9 = e
∴ The x-coordinate of point Y is 9
∵
∴
∴
- Multiply both sides by 3
∴ 12 = f
∴ The y-coordinate of point Y is 12
* The coordinates of point Y are (9 , 12)

Susan said, "Venus is more than twice as far from the sun as Mercury is."
Is Susan correct? If so, write yes. If she is wrong, rewrite the statement to make it true.
You could change more to less, change the planets-do whatever you need to do to
make a TRUE statement for Susan.
A TRUE statement for Susan is: "Venus is less than twice as far from the Sun as Mercury is."
Given:
The distance of each planet from the Sun,
Mercury - 51,000,000
Venus - 10000000
Earth - 150000000
Susan said, "Venus is more than twice as far from the sun as Mercury is."
51,000,000 × 2 = 102,000,000
When we calculate twice the distance of Mercury from the Sun it is much greater than the actual distance of Venus from the Sun.
(102,000,000 > 10000000)
Hence, the statement is incorrect and so is Susan.
The correct statement should be:

A tablet and a digital camcorder are both on sale for 30% off. The regular price of the tablet is $185. The regular price of the camcorder is $140. Part A Find the sale price of the tablet. Explain. Part B What is the sale price of the camcorder?
Part A
We need to find the sale price of the tablet, i.e., after a discount of 30% was applied.
When we apply a discount rate d to a price P, the sale price S is given by:
[tex]S=(1-d)\cdot P[/tex]In this problem, the original price of the tablet, in dollars, is:
[tex]P=185[/tex]And the discount rate is:
[tex]d=30\%=\frac{30}{100}=0.3[/tex]Then, the sale price is given by:
[tex]S=(1-0.3)\cdot185=0.7\cdot185=129.5[/tex]Therefore, the sale price of the tablet is $129.50.
Part B
Now, we can use the same formula to find the sale price of the camcorder, using:
[tex]\begin{gathered} P=140 \\ d=0.3 \end{gathered}[/tex]We obtain:
[tex]S=(1-0.3)\cdot140=0.7\cdot140=98[/tex]Therefore, the sale price of the camcorder is $98.
In the diagram , AB and BC are both tangent to P
Since AB and BC are both tangent to the circle P, their length is the same.
So we have the following equation:
[tex]2x+7=31[/tex]Solving this equation for x, we have:
[tex]\begin{gathered} 2x=31-7 \\ 2x=24 \\ x=\frac{24}{2} \\ x=12 \end{gathered}[/tex]So the value of x is 12, therefore the correct option is the first one.
The measure of ∠ABD is (0.19x+65)° and the measure of ∠CBD is (0.06x+50)°. Find the value of x.
Supplementary angles are those angles that add up to 180 degrees.
In this case, analyzing the figure shown in the exercise, you can identify that the angle ABD and the angle CBD are Supplementary angles.
Based on the explained above, you can set up the following equation:
[tex]m\angle ABD+m\angle CBD=180[/tex]Knowing that:
[tex]\begin{gathered} m\angle ABD=0.19x+65 \\ m\angle CBD=0.06x+50 \end{gathered}[/tex]You can substitute them into the first equation:
[tex](0.19x+65)+(0.06x+50)=180[/tex]Finally, solve for "x":
[tex]\begin{gathered} 0.19x+65+0.06x+50=180 \\ 0.25x+115=180 \\ 0.25x=180-115 \\ \\ x=\frac{65}{0.25} \\ \\ x=260 \end{gathered}[/tex]The answer is:

On his desk, Brandon has a stack of books.
The first one is 10 pages long, while the second one is 20 pages long. The second one has 40 pages, which is twice as much as the first.

80 times 2 =160
160 times 2=320

Annual starting salaries for college graduates with degrees in business administration are generally expected to be between and . Assume that a confidence interval estimate of the population mean annual starting salary is desired. a. What is the planning value for the population standard deviation? b. How large a sample should be taken if the desired margin of error is ? Round your answers to next whole number. ? ? c. Would you recommend trying to obtain the margin of error? Explain.
Because of the very huge sample size, we do not advise attempting to acquire the $100 margin of error.
The annual starting salaries for college graduates with degrees are between $30,000 and $45,000.
The confidence interval is 95%.
The planning value of the population standard deviation is expressed as:
= ( 45000 - 30000 ) / 4
= 15000/4
= 3750
And, 95% confidence interval a is 0.05.
Using the standard normal table,
Z(0.025) = 1.96
(a) For error E = $500,
n = ( Z × S/E )²
n = ( 1.96 × 3750/500)²
n = 216.09 = 217
(b) For error E = $200,
n = ( Z × S/E )²
n = ( 1.96 × 3750/200)²
n = 1351
(c) For error E = $100
n = ( Z × S/E )²
n = ( 1.96 × 3750/100)²
n = 5403
Therefore, Due to the sample size being too huge, we do not advise attempting to achieve the $100 margin of error.

Sabreena is playing a card game, and the odds of her winning after drawing the next card are 5:7.
What is the probability of her not winning?
Enter your answer as a decimal rounded to the nearest thousandth, like this: 0.423
Giving that her probability of winning is 5:7, Her Probability of not winning is; 0.286
What is the Probability of not winning?
According to binomial probability distribution, the probability is usually given by the formula;
P(X = x) = nCx * p^(x) * (1 - p)^(n - x)
where;
p is probability of success
n = number of trials, or the sample size
x = the number of "successes" in the probability
Now, we are told that the probability of winning in the next card is 5:7. Writing this in fraction form is 5/7.
Now, we know that percentage of winning + percentage of losing equals to 1. Thus;
Percentage of not winning + 5/7 = 1
Percentage of not winning = 1 - 5/7
Percentage of not winning = 2/7
In percentage form, this gives us;
2/7 * 100% = 28.57% = 0.286
