The median of the afternoon (PM) group is 23.
How to solve for the medianTo find the median of a set of numbers, we need to arrange them in ascending order and find the middle value.
Arranging the numbers in ascending order:
7, 9, 10, 12, 13, 15, 15, 16, 21, 23, 25, 26, 28, 30, 35, 35, 37, 38, 44, 55
There are 20 numbers in the dataset, so the middle value would be the 10th number when arranged in ascending order. In this case, the median of the afternoon (PM) group is 23.
Therefore, the median of the afternoon (PM) group is 23.

Answer:
56.52 but you have to round so its 57
Step-by-step explanation:
You have to multiply 18 and pi so we will use 3.14 for pi. 18 times 3.14 will give you 56.52 but you have to round it so it will be 57. If the number is greater than 5 you round up but if it is less you round down.
A box contains 18 blue flashlights, 3 red flashlights, 7 silver flashlights, and 2 black flashlights. The flashlights are identical in size and shape. If one flashlight is chosen at random, what is the probability that the flashlight will be either blue or black?
The probability that the flashlight will be either blue or black is,
⇒ 20/30
What is mean by Probability?The term probability refers to the likelihood of an event occurring. Probability means possibility. It is a branch of mathematics that deals with the occurrence of a random event. The value is expressed from zero to one.
We have to given that;
A box contains 18 blue flashlights, 3 red flashlights, 7 silver flashlights, and 2 black flashlights.
Hence, Total number of flashlights are,
⇒ 18 + 3 + 7 + 2
⇒ 30
So, the probability that the flashlight will be blue is,
⇒ 18 / 30
And, the probability that the flashlight will be black is,
⇒ 2 / 30
Hence, the probability that the flashlight will be either blue or black is,
⇒ 18/30 + 2/30
⇒ 20/30

The probability of flashlight to be black or blue is 2/3. To find the probability of selecting a blue or black flashlight from a box, add the number of blue and black flashlights, then divide by the total number of flashlights.
We first find the total number of blue and black flashlights, which is 18 (blue) + 2 (black) = 20.
Then, we divide this by the total number of flashlights in the box (18 + 3 + 7 + 2 = 30) to get the probability.
The probability of choosing a blue or black flashlight is 20/30 = 2/3 = 0.67.

Among the given tables, only the table with y-values doubling as x increments by 1 represents an exponential function. This is characterized by a constant proportional rate of change in the y-values in relation to x.
Explanation:The question asks to identify which of the given tables models an exponential function. An exponential function is a mathematical function in the form [tex]f(x) = a · b^x,[/tex] where a is not zero, b is a positive real number not equal to 1, and x is any real number. The key characteristic of an exponential function is that the rate of change (the increase or decrease) is proportional to its current value, meaning as x increases, the value of y increases or decreases at a rate proportional to its current value.
x y
0 5
1 7
2 9
3 11
This does not represent an exponential function because the increase in y is linear.
x y
0 5
1 10
2 20
3 40
This table models an exponential function since each y-value is doubling as x increases by 1.
x y
0 5
1 6
2 8
3 11
This does not model an exponential function because the growth does not follow a constant ratio.
x y
0 5
1 10
2 15
3 20
This also does not represent an exponential function as the increase in y is linear, similar to the first table.
Therefore, the table that models an exponential function is the one where the y value doubles as x increments by 1.

A circus charges $5 per child ticket and $8 per adult ticket. There were 136 tickets sold for a total of $830. How many child tickets and how many adult tickets were purchased?
I know that I need to use c + a =136 and 5c + 8a = 830
Answer:
50 adult
86 child
Step-by-step explanation:
c + a =136
5c + 8a = 830
These are the two equations to use
c is the number of child tickets and a is the number of adult tickets
The total number of tickets is 136
The child tickets are 5 dollars apiece and the adult tickets are 8 dollars apiece and the total amount made is 830
I will use elimination
Multiply the first equation by -5
-5(c+a) = -5*136
-5c-5a =-680
Then add this to the second equation
-5c-5a =-680
5c +8a = 830
------------------------
3a = 150
Divide each side by 3
3a/3 = 150/3
a = 50
Now we can find c
a+c = 136
50 + c = 136
Subtract 50 from each side
50+c-50 =136-50
c = 86
Answer:
child tickets: 86
adult tickets: 50
Step-by-step explanation:
C + A = 136
C = 136 - A
5C + 8A = 830
5(136 - A) + 8A = 830
680 - 5A + 8A = 830
3A = 150
A = 50
C = 136 - 50
C = 86

Michael recorded the number of points his team scored for the first seven basketball games.
64, 58, 60, 52, 56, 62, 54
which box plot correctly represents the data?
Answer:
The first box.
Step-by-step explanation:
The minimum is 52, the max is 64, the median is 58.
The correct option is A.
Given,
The number of points scored for the first seven basketball games.
64,58,60,52,56,62,54
On arranging it in increasing order we get,
52,54,56,58,60,62,64
The above data is ungrouped data.
We know that, The median of ungrouped data is the middle term (when the total no. terms in data is odd) on arranging the data in ascending or descending order.
So here on arranging the above data, the middle term here is 58, hence the median here is 58.
The minimum score is 52 and the maximum score is 64.
On seeing the options we find that the option A is correct because here the minimum value is 52 and the maximum is 64 and median is exactly 58.
Hence, option A is correct.

A 10-foot ladder is leaning against a tree. The bottom of the ladder is 4 feet away from the bottom of the tree. Approximately how high up the tree does the top of the ladder reach? 2.4 feet 6.0 feet 9.2 feet 10.8 feet
Answer:
C
Step-by-step explanation:
If we were to draw a horizontal line from the bottom of the ladder to the bottom of the tree and then draw a vertical line from the bottom of the tree to the top of the ladder, we'd get a right triangle with legs as the distance between the bottom of the tree and the bottom of the ladder and the height of the ladder, and the hypotenuse is the length.
Here, we know the hypotenuse is 10 feet and that the bottom of the ladder is 4 feet away from the bottom of the tree, so use the Pythagorean Theorem to find the height:
h = [tex]\sqrt{10^2-4^2} =\sqrt{84}[/tex] ≈ 9.2 feet
The answer is C.
Answer:
9.2 feet
Step-by-step explanation:
The ladder forms a right angle triangle with the ground and the tree
10² = 4² + h²
h² = 100 - 16
h² = 84
h = 9.16515139

If the product of two integers is positive, their signs are positive or negative
Answer:
It could be both 2 positives, or 2 negatives.
Step-by-step explanation:
This is because a negative times a negative is a positive, and a positive times a positive is a positive.
If the product of two integers is positive, their signs can be either positive or negative.
If the product of two integers is positive, their signs are positive or negative.
To understand this, we need to consider the rules for multiplying integers. When we multiply two positive numbers or two negative numbers, the result is always positive. However, when we multiply a positive number and a negative number, the result is always negative.
For example, if we multiply +3 and +4, the result is +12. If we multiply -3 and -4, the result is also +12. But if we multiply +3 and -4, the result is -12.

A park has a shape of a regular hexagon of sides of 2km each.Ama walks a distance of 5km along the sides of the park.What is the direct distance between the start point and the end point?
Answer: 3.61km or √13
Step-by-step explanation:
Given Data:
Sides of hexagon = 2km each
Distance walked by Ama = 5km
Therefore;
Let Ama starting position be the origin.
With this She would travel along two edges and then go halfway along a third.
Her new x- coordinate would be
= 1 + 2 + 1/2 = 7/2
Because she travels a distance of 5km which translates to 2 and half side of the Hexagon
= 2*1/2
= 1km. On her x-coordinates
For her y-coordinate we use same principles as x-coordinates
= √3 + 0 - √3/2
= √3/2
Therefore her distance walked
= √ ( (7/2)^2 + (√ 3/2)^2 )
= √ ( 49/4 + 3/4 )
= √ 13
= 3.61km
