Answer:
The two most widely used measures of the “center” of the data are the mean (average) and the median. To calculate the mean weight of 50 people, add the 50 weights together and divide by 50 . To find the median weight of the 50 people, order the data and find the number that splits the data into two equal parts.

b) CN = WN, ∠C ≅ ∠W.
Prove RN = ON
Answer:
Step-by-step explanation:
Considering triangle CNR and triangle WNO, there are:
∠C = W
CN = WN
∠CNR = ∠WNO (2 opposite angles)
deduce triangle CNR = triangle WNO
deduce RN = ON

Solve the equation -8(n + 7) = -88. What are two ways to start solving this equation? Choose BOTH ways.
1) Subtract 7 from both sides.
2) Use the distributive property.
3) Add 8 to both sides.
4) Add 88 to both sides.
5) Divide both sides by -8.
Answer:
Divide each side by -8
Distribute
Step-by-step explanation:
-8(n + 7) = -88.
Method 1
Divide each side by -8
n+7 = 11
Subtract 7 from each side
n = 4
Method 2
Distribute
-8n-56= -88
Add 56 to each side
-8n = -32
Divide by -8
n=4
Answer:
Distributive property & dividing -8 on both sides.
Step-by-step explanation:
You can begin solving the equation by either using the distributive property or dividing -8 on both sides.
Distributive Property:
[tex]-8(n+7)=-88\\-8n-56=-88\\-8n=-32\\n=4[/tex]
Dividing:
[tex]-8(n+7)=-88\\n+7=11\\n=4[/tex]

If f(x) = -2x- 1 and g(x) = -x what is the value of f [g(2)]?
PLEASE ANSWER ACCURATELY
Answer:
[tex]\displaystyle f[g(2)] = 3[/tex]
Step-by-step explanation:
We are given the two functions:
[tex]\displaystyle f(x) = -2x - 1\text{ and } g(x) = -x[/tex]
And we want to find the value of:
[tex]\displaystyle f[g(2)][/tex]
First, evaluate g(2):
[tex]\displaystyle \begin{aligned} g(2) &= -(2) \\ &= -2\end{aligned}[/tex]
Substitute:
[tex]\displaystyle f[g(2)] = f(-2)[/tex]
Evaluate f(-2):
[tex]\displaystyle \begin{aligned} f(-2) &= -2(-2) - 1 \\ &= 4 - 1 \\ &= 3\end{aligned}[/tex]
Therefore:
[tex]\displaystyle f[g(2)] = 3[/tex]
You used 6 3/4 cups of sugar while baking muffins and nut bread for a class party. You used a total of 1 1/2 cups of sugar for the muffins. Your nutbread recipe calls for 1 3/4 cups of sugar per loaf. How many loaves of nutbread did you make?
Answer:
Step-by-step explanation:
1. Convert to decimals.
[tex]6\frac{3}{4}[/tex] = 6.75 cups of sugar - Total Sugar
[tex]1\frac{1}{2}[/tex] = 1.50 cups of sugar - Muffin Sugar
[tex]1\frac{3}{4}[/tex] = 1.75 cups of sugar - Nutbread sugar
2. Subtract muffin sugar from total sugar
6.75 cups total sugar - 1.50 cups fir muffins = 5.25 cups remaining
3. Divide remaining sugar by amount used per loaf nutbread
5.25 cups sugar / 1.75 cups for each loaf nutbread = 3
3 Loaves of nutbread were made.
According to the 2000 census, the population of a city was 935,426. According to the 2010 census, the population of the same city was 934,578. Taylor says the 2000 population was greater than the 2010 population.
1. - Construct an argument that supports Taylor's conjecture.
2. - In 1870, the population was seventy-two thousand, five hundred six. Lupita wrote 72,560. Construct a math argument that explains whether Lupita wrote the number correctly.
The Taylor is right and Lupita is wrong.
It is required to Construct a math argument.
What is a statement?A statement is a declarative sentence that is either true or false but not both. A statement is sometimes called a proposition. The key is that there must be no ambiguity. To be a statement, a sentence must be true or false, and it cannot be both.
Given:
In 2000 census, the population of a city was 935,426.
In 2010 census, the population of the same city was 934,578.
1. Taylor is correct because in the thousands place there is a a five for 2000 and 2010 it’s a 4.
2. Lupita is wrong it should be seventy-two thousand five hundred sixty.
Therefore, the Taylor is right and Lupita is wrong.

The area of a rectangle is 36 square centimeters. Give all possible whole-number dimensions of the rectangle. Which rectangle has the greatest perimeter?
Answer:
ALL POSSIBLE DIMENSIONS OF THE RECTANGLE (whole numbers):
1 cm and 36 cm (Perimeter = 74 cm)
2 cm and 18 cm (Perimeter = 40 cm)
3 cm and 12 cm (Perimeter = 30 )
4 cm and 9 cm (Perimeter = 26)
6 cm and 6 cm Perimeter= 24 (squares are also considered rectangles, this is a square because of equal sides)
The rectangle with the greatest perimeter consists of the dimensions 1 cm and 36 cm.
EXPLANATION:
I listed all possible factors of 36: 1, 2, 3, 4, 6, 9, 12, 18, 36
And have come up with 5 possible dimensions with numbers from the listed factors above (when the dimensions of each rectangle are multiplied the result will be 36/the area)
Multiplication is used because the area of a rectangle is length x width
And I used the formula for perimeter:
2 (l + w)
And found the greatest perimeter (74 cm) that belongs to the rectangle with the dimensions 36 cm and 1 cm.

If a 130 mile trip takes 2 hours, what was the speed?
How long does a 35 mile trip at 70 mph take?
Answer:
Question 1's answer is 75 mph
Question 2's answer is 30 minutes
Step-by-step explanation:
Answer:
1. 65mph
2. 1/2 hour
Step-by-step explanation:
1. The equation is D=R×T. Since the distance was 130 miles and the time was 2 hours, rewrite the equation as 130=2R. Divide both sides by 2 and you get R=65
2. Using the equation, write 35 miles as distance and 70 mph as rate: 35=70T. Divide both sides by 70: T=0.5, which is equal to 1/2 hour, or 30 minutes.

Answer:
y = -2x+7
Step-by-step explanation:
The slope intercept form of an equation is
y = mx+b where m is the slope and b is the y intercept
y = -2x +b
Substitute the point into the equation and solve for b
5 = -2(1)+b
5 = -2+b
Add 2 to each side
5+2 = -2+b+2
7=b
y = -2x+7
A map is drawn to a scale of 1 : 20 000.
The actual area of the grassland is 2.5 hectares. Calculate the area on the map, giving your answer in square centimetres. ( 1 hectare = 10 000 m² )
pls help thank you:>
Answer:
0.625 cm²Step-by-step explanation:
Scale factor:
k = 1/20000When applied to the area consider k² as a scale factor.
The actual area:
2.5 hectares = 25000 m² = 25000*100² cm² = 250000000 cm²The area on the map:
250000000 * (1/20000)² = 0.625 cm²
