answer:
x=-4/7 and the slope is 7
Answer:
3
Step-by-step explanation:
The slope of a line is the rate of change
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (2, 12 ) and (x₂, y₂ ) = (0, 4) ← 2 ordered pairs from the table
m = [tex]\frac{4-12}{0-2}[/tex] = [tex]\frac{-8}{-2}[/tex] = 4
y = 7x + 4 ← is in slope- intercept form
with slope m = 7
Difference between rates of change = 7 - 4 = 3

Applying the triangle sum theorem, the value of c in the triangle is: D. 95°
What is the Triangle Sum Theorem?
Based on the triangle sum theorem, the sum of all interior angles in a triangle equals 180 degrees.
Applying the triangle sum theorem, we have:
b = 180 - 45 - 80 = 55°
a = 180 - 100 - 50 = 30°
c = 180 - b - a = 180 - 55 - 30
c = 95°
Therefore, applying the triangle sum theorem, the value of c in the triangle is: D. 95°

Answers
Answer:
There was 56695 people in the previous population.
Step-by-step explanation:
Well, first you need to find the percentage, 15% of 66700.
Which is 10005
Then, you need to subtract 66700 by 10005 to get the previous population.

Mean: is the average of the numbers.
Median: The middle number found by ordering all data points and picking out the one in the middle (or if there are two middle numbers, taking the mean of those two numbers). Example: The median of 4, 1, and 7 is 4 because when the numbers are put in order (1 , 4, 7) , the number 4 is in the middle.

Answer: Triangle: x = 40 Line: x = 10
Explanation:
All angles of a triangle adds up to 180. So x + 50 + 90 (the square box represents a 90° angle) = 180
Simplify: x + 140 = 180
So x = 40°
A straight line is 180°
so 7x+110=180
7x= 70
x=10
Answer:
x = 40
x = 10
Step-by-step explanation:
Problem 1
The sum of all angle measures in any triangle is (180) degrees. In this problem, one is given that one of the angle measures is (50) another is (x) and the final is (90) degrees. A general rule is that when an angle has a box around, its degree measure is 90 degrees. One can apply this here by stating the following,
x + 50 + 90 = 180
Simplify,
x + 140 = 180
Inverse operations,
x + 140 = 180
-140 -140
x = 40
Problem 2
The degree measure of a straight line is (180) degrees, the two given angles in this picture form a straight line. Thus, the sum of their angle measures is (180) degrees. Form an equation off of this information and solve for (x),
110 + 7x = 180
-110 -110
7x = 70
/7 /7
x = 10

Would a dot plot or a histogram best represent the data presented here? Why?
A) Histogram, because a large number of scores are reported as ranges
B) Histogram, because a small number of scores are reported individually
C) Dot plot, because a large number of scores are reported as ranges
D) Dot plot, because a small number of scores are reported individually
Answers
Answer:
A
Step-by-step explanation:
histogram's report ranges
ex.
60 people in 20 - 29
20 people in 30 - 39
10 people in 40 - 49
A) Histogram is suitable for this data, as large number of scores are reported as ranges
Histogram is a form of graphical representation of data, presenting a group of data points in particular ranges.
Dot plot presents data simply by number of dots, on various data points.
In this case : students scores are not in individual numerical units, but in range. Scores : 20 to 29 ... 60 to 69
So, Histogram is suitable in this case, and not Dot Plot

Answer: it is online customers buy an average of five packs compared to walk-in customers, who buy an average of two packs
Step-by-step explanation: Tell me if its correct or not for you :))
The inference based on the median is: online customers by an average of five packs compared with walking customers who buy an average of two packs online.
What is the Median of a Dot Plot?
The median is a measure of dispersion, which can give us an idea of where most of the data points lie in the data distribution that is represented in a dot plot.
The median is the middle value, having equal data points on the right and to the left.
The median for online customers is between 5 and 6.
The median for walk-in customers is 2.
Therefore, the inference to make using the median is: online customers by an average of five packs compared with walking customers who buy an average of two packs online.

A. higher, lower?
B. same as, twice, half?

Answer: A
Step-by-step explanation: mean in math terms mean everything added together on a graph we now have an 8th grade class and a 7th grade class the 7th-grade class has 67 pets 6+14+15+16+10+6=67 and the 8th-grade class has 121 pets 3+8+21+36+35+18=121 so it would be A.
the mean number of pets for the 8th-grade class is about 1.4 pets higher than the mean number of pets for the 7th grade class. This different is about lower the mean absolute deviation of either group.
