Myra polled twenty-five students in her class to determine the number of movies the students attended at the theater this year. The results are in the table. She decided to find the mean of a sample using Row 1 and Row 5.
What is the mean of her sample?
2
4
6
8
Answer: 4
Step-by-step explanation: How to find the mean of sample?
Mean of sample = (sum of data values of sample)/(size of sample)
(it is because size of sample = number of data values in sample)
For the given case, the population is
Row 1: 6 5 2 8 6
Row 2: 2 0 4 5 2
Row 3: 3 4 3 0 1
Row 4: 5 2 6 3 3
Row 5: 2 3 2 2 4
The sample Myra select is: Row 1 and Row 5.
Sample values are: 6, 5, 2, 8, 6, 2, 3, 2, 2, 4
Mean of sample = (6+5+2+8+6+2+3+2+2+4)/10 =40/10 = 4
Thus, The mean of Myra's sample is 4

For all of these, it involves the exterior angle theorem.
It states that the sum of the two opposite interior angles (not the adjacent/supplementary) is equal to the corresponding exterior angle. You can rearrange the equation of the others to satisfy this rule.

Jess is having a cake so she buys cake mix and decorate the cake with frosting just must been $62 baking pans and $2.50 for each box cake mix eggs and oil complete the table giving the total cost just will spend to meet each specific number of cakes
Number of cakes
15, 30, 50
A. 15 cakes cost $37.50. 30 cakes cost $75. 50 gigs cost $125
B. 15 cakes cost $99.50 30 gigs cost $137. 50 gigs cost $187
C. 15 cakes cost $99.50. There any cakes cost $75. 50 gigs cost $125
The correct option is B.
Here's the breakdown of the cost calculation:
15 cakes:
Cake mix: $2.50 x 15 = $37.50
Baking pans: $62
Total: $37.50 + $62 = $99.50
30 cakes:
Cake mix: $2.50 x 30 = $75
Baking pans: $62
Total: $75 + $62 = $137
50 cakes:
Cake mix: $2.50 x 50 = $125
Baking pans: $62
Total: $125 + $62 = $187
So the correct option is B

According to the information in the image, it can be inferred that the length of these would be 6, 8, 6, 8.
How to identify the length of the sides of this figure?To identify the length of the sides of this figure we must take into account the lengths shown in the model on the left. In this case we know that this figure is 6 high, 2 long and 8 wide.
Then the lengths that have an intermediate size would be 6, the longest lengths would be 8 and the shortest would be 2. From the above we can infer that the squares on the right side of the figure would be filled as follows: up: 6, 8, 6, 8.

PLEASEE ANSWER ASAPP!!
The system of linear equations −3x + 2y = −6 and y equals negative one half times x plus 4 is graphed on a coordinate plane. Approximate the solution to the system.
Answer: the solution to the system of equations is approximately (3.5, 2.25)
Step-by-step explanation:
The first equation can be rewritten in the form y = mx + b, where m is the slope and b is the y-intercept, by solving for y:
-3x + 2y = -6
2y = 3x + 6
y = (3/2)x + 3
The second equation already has the form y = mx + b:
y = -1/2 x + 4
Now that both equations are in the form y = mx + b, we can graph them on a coordinate plane and find the point at which they intersect, which is the solution to the system. The x and y coordinates of the intersection point are the values that satisfy both equations simultaneously.
The x and y values of the intersection point can be found either by solving for x and y or by using the method of substitution.
By using substitution, we can substitute the value of y from the second equation into the first equation to solve for x:
-3x + 2(-1/2 x + 4) = -6
-3x + (-x + 8) = -6
-4x + 8 = -6
-4x = -14
x = 3.5
Now that we have found x, we can substitute it into either equation to find y:
y = -1/2 x + 4
y = -1/2 * 3.5 + 4
y = 2.25
So, the solution to the system of equations is approximately (3.5, 2.25).
A line passes through the points (2,2) and (3,9). What is its equation in point-slope form?

I need to find whether its a adjacent angle or vertical on both
Answer:
1. Vertical angles
x = 113°
2. Adjacent angles
x = 28
Step-by-step explanation:
1)
Vertical angles have the same measurement. They are across from one another.
2) Adjacent angles are next to each other.
These angles are complementary. That means that together they add to 90
56 + x + 6 = 90 Combine like terms
62 + x = 90 Subtract 62 from both sides
62 - 62 + x = 90 - 62
x = 28

Answer:
5 Pints total
Each person gets 5 pints
Step-by-step explanation:
There is a 9/10 and a 1/10 which makes 1
There are 2 2/10 and 2 8/10 which makes 2
There is a 4/10 and a 6/10 which makes 1
There are 2 5/10 which makes 1
This adds up to a total of 5 pints.
If the question is how many pints are in each drink for them all to be equal it would be 5/10 or 1/2 pints each because there are 5 pints and 10 people with milk.
