2. Solve the equation. What is the value of y?
Which expression would be easier to simplify if you used the commutative property to change the order of the numbers?
A. 20 + 17 + (-1/2) + (-5/2)
B. 2/3 + (-1/3) + 5
C. (-17) + 45 + (-33)
D. 20 + 80 + (-32)
9514 1404 393
Answer:
C. (-17) + 45 + (-33)
Step-by-step explanation:
The order seems appropriate for A, B, D:
A. = 37 -6/2 = 34
B. = 1/3 +5 = 5 1/3
D. = 100 -32 = 68
I would rearrange the numbers in C to put the negative numbers together:
C. = (-17) +(-33) +45 = -50 +45 = -5
Answer:
c. is the right answer :) hope this helps
if g is the midpoint of ab, classify each triangle by its angles and sides
Answer:
CFE: Right triangle.
BCE: Acute
BFG: Equilateral
GAF: Obtuse
Step-by-step explanation:
Remember the types of triangles, first the CFE creates a right angle, which is a 90º angle between two of the sides that would be where F is located, so that would be a right triangle.
BCE is an acute triangle since all of its angles are lower than 90º so you don't have any larger than 90º angles, and its sides are not equal to eachother, so different sides and angles below 90º is an acute triangle.
BFG is an equilateral triangle since all of its sides are equal, and it is demonstrated in the figure by putting a little line in the middle of the sides that means that the sides are equal since the three sides of the triangle have them they are all equal making it an equilateral triangle.
GAF is an obtuse triangle, since all of its side are different and it has an angle larger than 90º that creates an obtuse triangle because of its obtuse angle.
Each of the triangles are classified as;
ΔCFE: Right angle triangle.
ΔBEC: Acute triangle
ΔBFG: Equilateral triangle
ΔGAF: Obtuse triangle
1) For the triangle ΔCFE, we can see that it has a right angle at point F. Thus, ∠CFE = 90°. Therefore, we can call ΔCFE right angled triangle.
2) For the triangle ΔBEC, we can see that the three angles namely;∠BEC, ∠BCE, ∠EBC are all less than 90°. Any triangle where the three angles are less than 90° is called acute triangle.
3) For the triangle ΔBFG, we can see that the three sides are equal. Any triangle with it's 3 sides equal is called equilateral triangle.
4) For the triangle ΔGAF, we can see that one of the angles which is ∠G is greater than 90° and any triangle with one of its's angles greater than 90° is called obtuse triangle.

Question 3 of 10
Solve the inequality and enter your solution as an inequality in the box below,
using "<="fors or ">" for 2 if necessary.
-2(5x + 1) > 48
Answer here
The solution to the inequality is x < -5.
To solve the inequality -2(5x + 1) > 48, we need to isolate the variable x. Let's simplify the equation step by step:
-2(5x + 1) > 48
Start by distributing -2 to the terms inside the parentheses:
-10x - 2 > 48
Next, isolate the variable by adding 2 to both sides of the inequality:
-10x - 2 + 2 > 48 + 2
-10x > 50
Now, divide both sides by -10, remembering to flip the direction of the inequality when dividing by a negative number:
(-10x) / (-10) < 50 / (-10)
x < -5
This means that any value of x that is less than -5 will satisfy the original inequality. To express the solution using an inequality symbol, we write x ∈ (-∞, -5). The symbol (-∞, -5) represents the interval of all real numbers less than -5, including -5 itself.

How to write a equation from a graph
Answer:
The bottom numbers comes first and then the side
Step-by-step explanation:
If i had a graph and i was using gallons per hour i would put gallons on the bottom and hours on the side
Answer/Step-by-step explanation:
So, if there is line on the graph and we need to get its equation in slope-intercept for (y = mx+b where m is the slope and b is the y-intercept). First, we have to take two points that lie on that line. Then, we will use the slope formula (m = y2 - y1 / x2 - x1). Once we get the slope, we have to find the y-intercept aka the b - value in the equation. So, to find this we have to take one of the coordinate point (that lies on the graph and was used to find the slope) and the slope. When you get the b - value, you have to substitute that value and the slope value into the equation. This is how you can write an equation from a graph.
Ex. (2, 3), (4, 9)
m = 9 - 3 / 4 - 2
m = 6/2
m = 3 <--- This is the m value aka the slope
y = mx + b (In this case, we will use the first point which is (2,3)).
3 = 3(2) + b
3 = 6 + b
b = -3
y = 3x -3

Two angles are complementary . One angle measures 27 . Find the measure of the other angle . Show your work and / or explain your reasoning
Answer:
153°
Step-by-step explanation:
Two angles are complementary . One angle measures 27 . Find the measure of the other angle . Show your work and / or explain your reasoning
Two angles are called supplementary when their measures add up to 180 degrees.
so
180 - 27 = 153°
Pew Research Center is a nonpartisan polling organization that provides information about issues, attitudes, and trends shaping America. In a poll, Pew researchers found that 73% of teens aged 13–17 have a smartphone, 15% have a basic phone and 12% have no phone. The study also asked the respondents how they communicated with their closest friend. Of those with a smartphone, 58% responded texting, 17% social media and 10% phone calls. Of those with no smartphone, 25% responded texting, 29% social media and 21% phone calls. (Pew Research Center website, October 2015).
Required:
a. One statistic (58%) concerned the use of texting to contact his/her closest friend, if the teen owns a smartphone. To what population is that applicable?
b. Another statistic (25%) concerned the use of texting by those who do not own a smart- phone. To what population is that applicable?
c. Do you think the Pew researchers conducted a census or a sample survey to obtain their results? Why?
Step-by-step explanation:
from the available data in this question,
1.
this population is applicable to those teenagers in the study who are aged 13 to 17 years and who own a smartphone
2.
from the question, this population is applicable to the the teenagers in the study within the age of 13 to 17 years who do not own a smartphone.
3. pew research conducted a sample survey and not a census to obtain their results. it would be illogical and not practical to conduct a census. A sample survey is better for this since it would cost less, save more time and also the members of the survey can easily be picked from the american teenage population.. a census would require data for the full population compared to sample survey which would only require a subgroup of the teenage population.

QUESTION 2 Brewsky's is a chain of micro-breweries. Managers are interested in the costs of the stores and believe that the costs can be explained in large part by the number of customers patronizing the stores. Monthly data regarding customer visits and costs for the preceding year for one of the stores have been entered into the regression analysis and the analysis is as follows: Average monthly customer-visits 1,462 Average monthly total costs $4,629 Regression Results Intercept $1,496 b coefficient $2.08 R2 0.86814In a regression equation expressed as y = a + bx, how is the letter b best described? (CMA adapted)
Answer:
b is the amount by which the costs of the stores (i.e. y) will increase whenever the number of customers patronizing the stores (i.e. x) increases by one.
Step-by-step explanation:
How is the letter b best described?
b is the amount by which the costs of the stores (i.e. y) will increase whenever the number of customers patronizing the stores (i.e. x) increases by one.
That is, b is the coefficient of letter x and it indicates that whenever there is a one unit increase in the number of customers patronizing the stores (i.e. x), the costs of the stores (i.e. y) will increase by $2.08.
To give an example, the regression equation in the question is expressed as:
y = a + bx ............................ (1)
Where;
y = the costs of the stores = ?
a = Intercept = $1,496
b = coefficient = $2.08
x = the number of customers patronizing the stores = ?
Assume x = 1, we can predict y by substituting the values to obtain y1 as follows:
y1 = $1,496 + ($2.08 * 1) = $1,496 + $2.08 = $1,498.08
Now, assume x increases by 1 to 2 i.e. x = 2, we can predict y by substituting the values to obtain y2 as follows:
y2 = $1,496 + ($2.08 * 2) = $1,496 + $4.16 = $1,500.16
The the change is y as a result of one unit increase in x from 1 to 2 can then be obtained as follow:
Change in y = y2 - y1 = $1,500.16 - $1,498.08 = $2.08.
This therefore cofirms that b indicates that whenever there is a one unit increase in the number of customers patronizing the stores (i.e. x), the costs of the stores (i.e. y) will increase by $2.08.

So, 1 inch = 1/12 ft
or, 3 inches = 3/12 = 0.25 ft.
So the height of Amir is = 5 ft 3 inch = 5.25 ft.
Let the height of the dinosaur is = x.
