Answer:
1) 22
2) 19.5
3) 26
4) 12
5) False
6) True
7) Mean
8) False
9) Add all the numbers and divide by the total number of numbers
10) Bimodal
Step-by-step explanation:
1)Use the data to calculate the mean. 24, 31, 12, 38, 12, 15 *
To calculate mean you add all the numbers up and divide by the total number of numbers.
\(\frac{24 + 31+12+38+12+15}{6} = 22\)
2) Use the data to calculate the median. 24, 31, 12, 38, 12, 15 *
For median, arrange the numbers from lowest to largest
12, 12, 15, 24, 31, 38
use (n+1) / 2 to figure out which value is the median
(6+1) / 2 = 3.5 (median is in between the 3rd and 4th value)
(15+24) / 2 = 19.5
3) Use the data to calculate the range. 24, 31, 12, 38, 12, 15 *
Range is max value - min value
38 is max and 12 is min
38 - 12 = 26
4) Use the data to calculate the mode. 24, 31, 12, 38, 12, 15 *
Mode is the value that appears most frequently
In this case 12 appears 2 times, therefore it is the mode
5) the mode represents the number that appears the least *
False, mode is the number that appears the most
6) To calculate the range we use the highest and lowest number ? *
True
7) Average is another word for *
mean
8) the range indicates the middle number ? *
False, range is the max value - min value
9) which statement best describes the mean. *
add all the numbers and divide by the total number of numbers
10) A data set with two modes is known as *
bimodal

Given data=24,31,12,38,12,15summation fX=132
N(total no.of items)=6
Now,
Mean=summation FX/N
=132/6
=22
2. Arranging the data in ascending order
= 12,12,15,24,31,38
N=6
Median=(N+1/2)th item
= (6+1/2) th item
=(7/2)th item
=3.5 th item
Again,
median=3 rd item + 4th item/2
=15+24/2
= 39/2
=19.5
3.Range= highest score- lowest score
=38- 12
=26
4. Mode= 12 because it has more frequency.

Answer:
(a) The scale factor is 2.5 and the coordinates of point C are (–2.4, –0.8)
Step-by-step explanation:
We are given ...
A(-4, 3.2) and A'(-10, 8)
C'( -6, -2)
__
The scale factor is the ratio of corresponding coordinates:
A'x/Ax = -10/-4 = 2.5 . . . scale factor
Then the coordinates of C will be ...
C' = 2.5C
C = C'/2.5 = (-6, -2)/2.5

(GIVING BRAINLIEST) Gavin has two bags of tiles. The numbers and colors of the tiles are shown in the table.
If Gavin randomly draws one tile from each bag, what is the probability that he will select two red tiles?
a. 2/9
b. 1/6
c. 1/18
d. 1/3
Answers
The probability that Gavin will select two red tiles when he randomly draws one tile from each bag is 1/18. So, option C is the correct answer.
What is the probability of an event?The probability of an event is a fractional value determining how likely an event is to occur. The formula of the probability of an event =
The number of favorable outcomes to an event/total number of outcomes in that event.
What are independent events?Two events A and B are said to be independent when the occurrence is not related to the occurrence of the other.
The probability of independent events is given by:
Probability(both A and B occurs) = Probability(A occurs)*Probability(B occurs)
How do we solve the given question?We are informed that Gavin has two bags of tiles, and he draws one tile from each bag.
We are asked to find the probability that he will select two red tiles.
Let the event of drawing a red tile from bag 1 be A and bag 2 be B.
Since the two bags are different, A and B are independent events.
Now, the number of red tiles in bag 1 = 3. These are in favor of A.
The total number of tiles in bag 1 = 18.
∴ Probability(A) = 3/18
or, P(A) = 1/6.
Now, the number of red tiles in bag 2 = 3. These are in favor of B.
The total number of tiles in bag 2 = 9.
∴ Probability(B) = 3/9
or, P(B) = 1/3.
Since A and B are independent, the occurrence of A and B together is,
Probability (A and B) = P(A)*P(B)
or, P(A and B) = 1/6 * 1/3 = 1/18.
∴ The probability that Gavin will select two red tiles is 1/18.
Hence, option C. is the correct option.

Elisa and Benjamin survey a random sample of 50 students at their school about which superpower they would most like to have. The table shows their data. a. Elisa claims that about 20% of the students at the school would choose mind reading as their superpower. Is this claim supported by the sample data? c. Benjamin claims that no students at the school would choose healing as a superpower. Is Benjamin's claim definitely correct? Why or why not?
Answers
Since 6 out of 50 students (or 12%) chose mind reading. This is lower than Elisa's claim of 20%, so her claim is not supported by the sample data.
How to known if the claim supported by the sample data?a. To determine whether Elisa's claim is supported by the sample data, we need to calculate the proportion of students in the sample who chose mind reading as their superpower. From the table, we can see that 6 out of 50 students (or 12%) chose mind reading. This is lower than Elisa's claim of 20%, so her claim is not supported by the sample data.
c. Benjamin's claim that no students at the school would choose healing as a superpower is not definitely correct. From the table, we can see that 4 out of 50 students (or 8%) chose healing as their superpower. While this is a relatively small proportion, it is not zero, so Benjamin's claim is not definitely correct.
However, we should be cautious in drawing conclusions about the larger population of all students at the school based on a small sample of only 50 students.

He made a mistake. When you change a division to a multiplication, you must use the reciprocal of the second fraction. You have to flipt the second fraction. He did not flip it.

The area of triangle ABD is 50cm, and one of its sides is 10cm in length. Find one of the heights of the triangle.
Answers
Answer:
10cm
Step-by-step explanation:
If you want to find one of the heights of the triangle, you need to use some math magic. The magic spell is:
A = (1/2) * b * h
where A is the area, b is the base, and h is the height. Don't ask me why, it just works.
Now, we know that the area of triangle ABD is 50 cm and one of its sides is 10 cm. We can pretend that this side is the base of the triangle. Why? Because it makes our life easier. Trust me.
Then we put these numbers into the magic spell and we get:
50 = (1/2) * 10 * h
Now we need to solve for h, which is the height we want. To do that, we need to do some algebra. Don't worry, it's not that hard. Just follow these steps:
- Multiply both sides by 2. This gives us:
100 = 10 * h
- Divide both sides by 10. This gives us:
10 = h
- Celebrate! We found the height!
So, one of the heights of the triangle is 10 cm. Isn't math fun?
Area of triangle = 1/2 × base × height
We know the area of the triangle is 50 cm², and one of the sides (which is also the base) is 10 cm. Let's substitute these values in the formula and solve for the height:
50 = 1/2 × 10 × height
Multiplying both sides by 2, we get:
100 = 10 × height
Dividing both sides by 10, we get:
height = 10 cm
Therefore, the height of triangle ABD is 10 cm.

norm has $25 from his birthday to start with and plans to add $7 each week
Answers
Answer:
Total amount = 7x + 25
Step-by-step explanation:
Assuming that week can be denoted by a variable, in this case, x. Also assume that the total amount owned is denoted by the variable, y.
Note that $25 is the constant, meaning that that amount will not change. Norm would technically have at least $25 regardless of how much week passes.
The amount that changes per week is the addition of $7.
Set the equation:
Total amount = ($7 per week x amount of week(s)) + starting amount (constant).
Total amount = 7x + 25
