If I get a 100 on one assingment and a 57 on the other, what is my average of the assignments?
Answer:
78.5
Step-by-step explanation:
Add the two scores, and then divide this sum by 2 to obtain the average score:
[tex] \frac{100 + 57}{2} = \frac{157}{2} = 78.5[/tex]
Answer:
78.5
Step-by-step explanation:
To calculate the average of the assignments, you must find the mean of the assignments.
Mean = sum of the items divided by the number of items
[tex]\frac{100+57}{2}[/tex]
[tex]=\frac{157}{2}[/tex]
[tex]=78.5[/tex]
The sum of all but one interior angle of a heptagon is 776°. What is the measure of the final interior angle? 42º 56º 124º 304º.
Answer:
124°
Step-by-step explanation:
the sum of the interior angles of a polygon is
sum = 180° (n - 2) ← n is the number of sides
here n = 7 ( heptagon has 7 sides ) , then
sum = 180° × 5 = 900°
let x be the final interior angle , then
776° + x = 900° ( subtract 776° from both sides )
x = 124°

C. 124

Answer: A. an incorrect decision when the null hypothesis is false
Explanation:
A type I error is when we reject the null, but the null was true.
A type II error is when we fail to reject the null, but the alternative was true.

Hey there!
0.860(17) + 3.302 = 10
= 0.86(17) + 3.302
= 14.62 + 3.302

What is 1050 rounded to the nearest thousand?
Answer:
1100
Step-by-step explanation:
We round the number up to the nearest hundred if the last two digits in the number are 50 or above.
We round the number down to the nearest hundred if the last two digits in the number are 49 or below.
If the last two digits are 00, then we do not have to do any rounding, because it is already to the hundred.

Find the AREA OF THE BASE of the
cylinder!
base is 10yd and height is 15yd
Instructions: Find the measure of the indicated angle.
Answer:
x = 35
Step-by-step explanation:
As it is an isosceles triangle, two sides are equal (that's why we took two x)
2x = 180- 110
2x = 70
x = 70/2
x = 35
I hope my answer helps you.
The measure of the indicated angle is 35 degrees.
What is the angle sum property?
A triangle is a polygon that has three sides and three vertices. It is one of the basic figures in geometry.
The angle sum property of a triangle states that the sum of the interior angles of a triangle is 180 degrees.
We are given that;
Angle = 110degree
Now,
x+x+110=180
2x+110=180
2x=180-110
2x=70
x=70/2
x=35
Therefore, by the angle sum property of triangles the answer will be 35degree.

10 One of the legs of a right triangle has vertices with coordinates (-2,4) and (10,0).
What is the equation of the line of the other leg of the right triangle if it shares the vertice of (10,0)?
The equation of the line of the other leg of the right triangle if it shares the vertice of (10,0) is y = -1/3x + 10/3
How to find the equation of a line?The equation of a line in slope-intercept form is expressed as y = mx + b
where
m is the slope
b is the y-intercept
Given the coordinate points (-2, 4) and (10, 0)
Find the slope
Slope = -4/12
Slope = -1/3
Determine the y-intecept
0 = -1/3(10) + b
b = 10/3
Determine the equation
y = -1/3x + 10/3
Hence the equation of the line of the other leg of the right triangle if it shares the vertice of (10,0) is y = -1/3x + 10/3

#6 You want to find out what type of pet is most commonly adopted from the shelter. Over the course of a month, you randomly survey 40 people who have just adopted a pet. Of those 40 people, 23 adopted dogs. If about 4,500 people adopt pets each year, about how many can you predict will dogs?
Answer:
we predict 2,587 persons will adopt dogs
Step-by-step explanation:
out of 40 persons 23 adopt dogs
Then
out of 40×25 persons 23×25 adopt dogs
Then
out of 1000 persons 575 adopt dogs
Then
out of 1000×4.5persons 575×4.5 adopt dogs
Then
out of 4,500 persons 2,587.5 adopt dogs
Method 2 :
Let x Ben the number of persons we predict they will adopt dogs:
Here we have a proportional relationship:
Then

It is common knowledge that a fair coin lands heads up 50% of the time and tails up 50% of the time. For fair coins, a probability of 0 is assigned to the coin landing on its edge. But what if several coins were glued together? A teacher claims that if 10 pennies were glued together and flipped many times, the penny stack would land on heads 25% of the time, tails 25% of the time, and on its edge 50% of the time. To investigate this claim, a student glues 10 pennies together and flips the stack 200 times. The student would like to know if there is convincing evidence that the distribution differs from what the teacher claimed. What are the appropriate hypotheses?
H0: The distribution of flips is 25% heads, 25% tails, and 50% edge.
Ha: The distribution of flips is not 25% heads, 25% tails, and 50% edge.
H0: The distribution of flips is not 25% heads, 25% tails, and 50% edge.
Ha: The distribution of flips is 25% heads, 25% tails, and 50% edge.

Ha: The penny stack will not land on heads 50 times, tails 50 times, and on its edge 100 times when flipped 200 times.
H0: The penny stack will not land on heads 50 times, tails 50 times, and on its edge 100 times when flipped 200 times.
Ha: The penny stack will land on heads 50 times, tails 50 times, and on its edge 100 times when flipped 200 tim
Answer:
The penny stack will land on heads 50 times, tails 50 times, and on its edge 100 times when flipped 200 times
Step-by-step explanation:
25% of 200=50

2y - 3x = 6
The lines represented by these equations are

Using linear function concepts, it is found that the two lines can be classified as:
(4) intersecting, but not perpendicular.
What is a linear function?A linear function is modeled by:
y = mx + b
In which:
m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.b is the y-intercept, which is the value of y when x = 0, and can also be interpreted as the initial value of the function.The slope defines if the lines are parallel or perpendicular, as follows:
If they are parallel, they have the same slope.If they are perpendicular, the multiplication of the slopes is of -1.If the multiplication of -1, and the slopes are different, they are intersecting.In this problem, the lines in slope-intercept formula are:
[tex]y = \frac{2}{3}x - 2 \rightarrow = m = \frac{2}{3}[/tex]
[tex]y = \frac{3}{2}x + 3 \rightarrow m = \frac{3}{2}[/tex]
Then:
[tex]\frac{2}{3} \times \frac{3}{2} = 1[/tex]
So they are intersecting and not perpendicular, which means that option 4 is correct.

Answer:
4 in
Step-by-step explanation:
18 + 22 + 15 + 28 + 17 = 100
100 / 5 = 20
So, the mean for the data set: 18, 22, 15, 28, 17 is 20.
18 - 20 = |2|
22 - 20 = |2|
15 - 20 = |5|
28 - 20 = |8|
17 - 20 = |3|
2 + 2 + 5 + 8 + 3 = 20
20 / 5 = 4
So, 4 in is the mean absolute deviation (MAD).
I also took the test.
