Answer:
Step-by-step explanation:
Part A:
Mark did not round to the nearest hundreds, he rounded to the nearest tens.
Option A (Incorrect):
271 and 582 are normally not rounded down, unless we are using limits coming from the left and a unique equation.
Option B (Incorrect):
271 as the same problem as option A, but 582 rounding to 600 is correct. It doesn't make sense to round both numbers differently, unless stated.
Option C (Incorrect):
271 rounding to 300 is correct, but 582 is not normally rounded down to 500 unless we are using limits coming from the left and a unique equation. Unless stated, don't round both numbers differently.
Option D (Correct):
271 rounded to 300 and 582 rounded to 600 looks correct for rounding to the hundreds.
Part B:
There are two ways to solve this question:
One way:
271 + 582 = 853
Round 853 to the nearest hundred for 900
(Note: Round 853 to the nearest tens for 850.)
Second way:
271 + 582
Round Numbers:
300 + 600
= 900

Answer:
x = 35 , y = 72.5
Step-by-step explanation:
(a)
x and 35° are vertical angles and are congruent, then
x = 35
(b)
y. y and 35 lie on a straight line and sum to 180°, that is
y + y + 35 = 180
2y + 35 = 180 ( subtract 35 from both sides )
2y = 145 ( divide both sides by 2 )
y = 72.5
Answer:
y = 72.5 degrees
X = 35 degrees
Step-by-step explanation: A straight line is 180 degrees. The line with the two y degrees and the 35 degrees is a straight line, which is = 180 degrees. Because the y degrees are the same variable (y) they are equal degrees. All you need to do to find y is 180-35 =145. Divide that by 2 to find both y’s. 145 / 2 = 72.5. You can do the same for x, or realize that x and 35 are alternate interior angles, meaning they are the same measure: 35 degrees.
Identify the volume of the composite figure. Round to the nearest tenth.
Answer:
474.5 ft³
Step-by-step explanation:
volume of cube = l³ = 9³ = 729
volume of the cylinder = πr²h = π × 3² × 9 = 81π
subtracting,
729-81π = 474.5309951 ft³
Answer:
474.5 ft³

Which statement is true about a trend line?
Answer:
Its b
Step-by-step explanation:
I did the test...
The correct statement about a trend line is: A trend line and a regression line are equivalent terms.
A trend line and a regression line are NOT equivalent terms. They refer to different concepts in data analysis.
1. Trend Line:
A trend line, also known as a line of best fit, is used to represent the general direction or pattern of a dataset. It is a straight line that fits through the data points in a scatter plot to show the overall trend in the data. The primary purpose of a trend line is to identify the underlying pattern or tendency of the data points. Trend lines can be linear or nonlinear, depending on the nature of the data.
In simple terms, a trend line helps us visualize whether the data is increasing, decreasing, or following a specific pattern over time or across a range of values.
2. Regression Line:
A regression line is a specific type of trend line used in linear regression analysis. Linear regression is a statistical method that examines the relationship between two or more variables to predict an outcome. It finds the "best-fit" straight line that minimizes the sum of the squared differences between the actual data points and the predicted values.
The regression line represents the relationship between the independent variable(s) (usually denoted as 'X') and the dependent variable (usually denoted as 'Y'). It provides an equation of the form Y = a + bX, where 'a' is the y-intercept and 'b' is the slope of the line. The regression line serves as a predictive model to estimate the value of the dependent variable based on the values of the independent variable(s).
- A trend line represents the general direction or pattern of a dataset.
- A regression line is a specific type of trend line used in linear regression to predict outcomes based on the relationship between variables.
Therefore, the correct statement is: A trend line and a regression line are NOT equivalent terms.

George is reading a book.On Monday he read 1/3 of the book. On Tuesday he reads three-tenths of the remaining pages. He has 35 pages left to read. How many pages are in the book
Answer:
Step-by-step explanation:
m=p/3
t=(3/10)(1-1/3)
t=(3/10)(2/3)=p/5
p-p/3-p/5=35
(15p-5p-3p)/15=35
7p/15=35
7p=525
p=75
So the book has 75 pages.
6⋅10 −2 6, dot, 10, start superscript, minus, 2, end superscript is how many times as large as 2 ⋅ 1 0 − 8 2⋅10 −8 2, dot, 10, start superscript, minus, 8, end superscript?
Answer:
6⋅10^ −2 is 3* 10^6 greater than 2 ⋅ 10^− 8
Step-by-step explanation:
Given the following expression
6⋅10^ −2 and 2 ⋅ 10^− 8
Taking their ratio
k = 6⋅10^ −2/2 ⋅ 10^− 8
k = 6/2 * 10^-2/10^-8
k = 3 * 10^{-2+8}
k = 3* 10^6
Hence 6⋅10^ −2 is 3* 10^6 greater than 2 ⋅ 10^− 8

5x +2(x3 - 9) = 132 + 8x?
Answer:
x = 50
Step-by-step explanation:
5x + 2(3x - 9) = 132 + 8x
5x + 6x - 18 = 132 + 8x
11x - 18 = 132 + 8x
11x - 18 = 8x + 132
11x - 18 + 18 = 8x + 132 + 18
11x = 8x + 150
11x - 8x = 8x - 8x + 150
3x = 150
3x ÷ 3 = 150 ÷ 3
x = 50

Find the area (in square feet) of a trapezoid with height h and bases b_1 and b_2. h = 6 in b_1 = 9 in b_2 = 12 in The area is _ square feet
Answer:
Area of the trapezoid = 90 square feet
Step-by-step explanation:
Area of a trapezoid with bases b₁, b₂ and height h is given by the formula,
Area of a trapezoid = [tex]\frac{1}{2}(b_1+b_2)h[/tex]
By substituting the given values in the formula,
Area = [tex]\frac{1}{2}(6+9)12[/tex]
= [tex]\frac{180}{2}[/tex]
= 90 square feet
Therefore, area of the trapezoid = 90 square feet
