Answer:
The answer is below
Step-by-step explanation:
a) If O(x, y) is the midpoint between two points X(x₁, y₁) and Y(x₂, y₂)m then the coordinates of O is:
x = (x₁ + x₂)/2; y = (y₁ + y₂) / 2
Since M(x, y) is the midpoint of AB, then the coordinates of M is:
x = (0 + 5) / 2 = 2.5; y = (1 + 0)/2 = 0.5
M = (2.5, 0.5)
b) The center of gravity is gotten by finding the average of the x coordinates and the y coordinates of the vertices of the triangle.
Let O(x, y) be the center of gravity of triangle ABC, hence;
x = (0 + 5 + 4) / 3 = 3
y = (1 + 0 + 2) / 3 = 1
O = (3, 1)

i think its a because its saying which one does not allow you to conclude that both triangles are congruent but the other ones are talking the sides and a is the only one thats talking about the angles. so i dont really know if its right but thats just an educated guess.

5. Amy deposited $7,000 in a bank account earning 3.5% interest, compounded
annually. Write an equation to represent how much money Amy will have after t
years.
Answer:
Step-by-step explanation:
Given the following data;
Principal = $7,000
Interest = 3.5% = 3.5/100 = 0.035
To find the future value, we would use the compound interest formula;
[tex] A = P(1 + \frac{r}{n})^{nt}[/tex]
Where;
A is the future value.
P is the principal or starting amount.
r is annual interest rate.
n is the number of times the interest is compounded in a year.
t is the number of years for the compound interest.
Substituting into the equation, we have;
[tex] A = 7000(1 + \frac{0.035}{n})^{nt}[/tex]

list all of your perfect squares
[tex]\sqrt{1}, \sqrt{4} ,\sqrt{9} , \sqrt{16} , ...\\[/tex]
So [tex]\sqrt{5}[/tex] is between [tex]\sqrt{4} and \sqrt{9}[/tex] so it is between 2 and 3
If that is a negative [tex]\sqrt{30}[/tex] then it is between square root of 25 and 36, which would be -5 and -6
-[tex]\sqrt{15}[/tex] is between [tex]\sqrt{9} and \sqrt{16}[/tex] so -3 and -4

A:149
B:153
C:225
D:297
Answer: 225 square feet
Step-by-step explanation:
We find the area of the 4 triangle and the area of the rectangle and thereafter we add everything together.
Area of triangle 1 = 1/2 base × height
= 1/2 × 12 × 8
=96/2
=48
Area of triangle 2 = area of triangle 1= 48( because the opposite triangle are congruent so they have equal base and height)
Area of triangle 3 = 1/2×base×height
= 1/2 × 6 ×9.5
= 57/2
=28.5
Area of triangle 4=Area of triangle 3 = 57 (the opposite triangle are congruent and so they have the same base and height hence the same area)
Area of the rectangle = length×breadth
=12 × 6 =72
Total surface area = addition of all the areas of the triangles and the rectangle
Total surface area= 48+48+57+57+72 = 225
Therefore, the total surface area is 225 square feet

Jordan ran 15LaTeX: \frac{3}{8}3 8 miles, while Ethan ran 12 LaTeX: \frac{1}{6}1 6 miles. How many miles did the boys run altogether?
Answer:
27 13/24 miles
Step-by-step explanation:
Given that:
Jordan = 15 3/8 miles
Ethan = 12 1/6 miles
Miles ran altogether :
15 3/8 + 12 1/6
123/8 + 73/6
(369 + 292) / 24
= 661 / 24
= 27 13/24
4kg of cheese costs £10.80 how much would 3kg cost
Answer:
£8.10
Step-by-step explanation:
Divide £10.80 by 4 to find the cost of 1 Kg, then multiply this by 3
£10.80 ÷ 4 = £2.70 ← cost of 1 Kg , then
cost of 3 Kg = 3 × £2.70 = £8.10
Answer:
it may helps......
Step-by-step explanation:
we can solve it by unitary method....So,
Cheese (in Kg). Cost (in Rs)
4kg 10.80
3kg X
Now, 4×x = 3×10.80
X=3×10.80/4 (by transposing)

A researcher has conducted a survey using a simple random sample of 50 licensed drivers to create a confidence interval to estimate the proportion of licensed drivers favoring the construction of a new stoplight. Assume that the sample proportion does not change. The researcher now decides to survey a random sample of 200 people instead of 50 licensed drivers. Which of the following statements best describes how the confidence interval is affected by this change?
The width of the new interval is about the same width as the original interval.
The width of the new interval is about twice the width of the original interval.
The width of the new interval is about one half the width of the original interval.
The width of the new interval is about one fourth the width of the original interval.
The width of the new interval is about four times the width of the original interval.

Mr. Monrean had three sheets of stickers. He gave 20 stickers from each sheet to his students and has 12 total stickers left. Write and solve an equation to find the total number of stickers s there were originally on each sheet.
Answer:
the total number of stickers is 24
Step-by-step explanation:
The computation of the total number of stickers is shown below
Let us assume the total no of stickers be x
Now as per the question, the equation is
3(x - 20) = 12
3x - 60 = 12
3x = 12 + 60
3x = 72
x = 24
Hence, the total number of stickers is 24
If a factor of a polynomial is x-5, what is the zero?
Answer:
x = 5
Step-by-step explanation:
Because the factor of the polynomial is x - 5, we can infer that the zero would be the solution of this equation: x - 5 = 0
Therefore, the zero is x = 5.

B) What was the temperature at the park at noon today? How many days are in the month of February this year? D) What are the ages of the dogs that live on this street? E) What is the color of the house at the end of the street?
Answer:
A and D are statistical questions because they will have more than one answer
Step-by-step explanation:
B is wrong bc there is only one specific temperature at noon
C is wrong because you just answer how many days there are
E is wrong because its only asking for a color of one house and not all the houses if it did ask for the colors of all the houses on the block, it would then be a statistical question.
Considering that there would be multiple solutions, questions A and D are statistical ones.
What is statistics?The study of gathering, analyzing, interpreting, presenting, and organizing data in a certain way is the focus of the mathematic branch known as statistics.
The act of gathering data, classifying it, presenting it in a way that makes it understandable, and then conducting additional analyses of the data is known as statistics.
As per the information given in the question,
Let check the options one by one,
Because there is just one particular temperature at noon, B is incorrect.
C is incorrect because you just responded with the number of days.
E is incorrect as it only requests the color of one house, not all the houses. If it did, it would be a scientific question asking for the hues of all the homes on the block.

In the equation y=2x+3,y represents the total number of preseason and regular season games that your softball team played this summer. The variable x represents the number of weeks in the regular season. Which statement is true?
Answer:
C. Your team plays 3 preseason games.
Step-by-step explanation:
In the equation y = 2x + 3, y represents the total number of preseason and regular season games that your softball team played this summer. The variable x represents the number of weeks in the regular season. Which statement is true?
A. The regular season lasts 2 weeks.
B. The preseason lasts 2 weeks.
C. Your team plays 3 preseason games.
D. Your team plays 3 regular season games each week.
Solution:
The equation for a linear function is given as:
y = mx + b;
where m is the rate of change and b is the y intercept (that is initial value of y at x = 0), y and x are variables.
Given that y = 2x + 3;
The slope (m) = 2 and the y intercept (b) = 3
This slope means 2 games are played every week during the regular season games. The y intercept means that at before the regular games have start, 3 games have been played. Therefore, the team plays 3 preseason games.
