Step-by-step explanation:
i took the test on edmentum and got it correct
From the histogram graph, it is clear that the graph is skewed left. Anabelle's score should be added to 60 - 70. 5 students scored below 70 on that day.
What is a histogram graph?''A histogram is a graphical representation that organizes a group of data points into user-specified ranges. Similar in appearance to a bar graph, the histogram condenses a data series into an easily interpreted visual by taking many data points and grouping them into logical ranges or bins.''
Given, a histogram that shows the test score results of Ms. Garrison's Algebra class.
1. Data in the histogram is skewed left as the graph is pretty higher on the right hand side and deeper on the left hand side.
2. Anabelle was absent on the day of the test but appeared on the next week. She scored 60. It will be added in the column of 60 - 70.
3. The students who scored less than 70 on that day of exam is = (3 + 2) = 5.

Answer:
(x, f(x)) = (1, 6), (2, 11), (3, 18), (4, 27)
Step-by-step explanation:
Each figure consists of two small squares and a square that has a side length of 1 more than the figure number. That is, ...
f(x) = (x +1)^2 +2
You can count the squares in figures 1-3. Figure 4 will be 2 more squares than 5^2 = 25, so will be 27 squares.
(x, f(x)) = (1, 6), (2, 11), (3, 18), (4, 27)
The solution to 9(x+2) = 5 - 2(x - 1) is
*Show your work*
Answer:
x=-1
Step-by-step explanation:
9(x+2) = 5 - 2(x - 1)
9x+18 = 5-2x+2
9x+18 = -2x+7
+2x = +2x +7
-----------------------
11x+18 = 7
-18 = -18
-----------------------
11x = -11
÷11 = ÷11
-----------------------
x = -1
Answer:
x = -1
Step-by-step explanation:
9(x+2) = 5 - 2(x-1)
9(x+2) = 5 - 2(x - 1)
9x+18 = 5-2x+2
9x+18 = -2x+7
+2x +2x
11x + 18 = 7
-7 -7
11x + 11 = 0
-11 -11
11x = -11
x = -1
You need a 45% alcohol solution. On hand, you have a 175 mL of a 25% alcohol mixture. You also have 70% alcohol mixture. How much of the 70% mixture will you need to add to obtain the desired solution?
175 mL at 25% concentration of alcohol contains 0.25 (175 mL) = 43.75 mL of alcohol. If v is the amount of the 70% solution that you use, then that amount contains 0.7v mL of alcohol.
Mixing these two yields a total volume of 175 mL + v, and it contains 43.75 mL + 0.7v alcohol. You want to end up with a concentration of 45%, which means the ratio of the amount of alcohol to the total volume needs to be 0.45:
(43.75 mL + 0.7v) / (175 mL + v) = 0.45
Solve for v :
43.75 mL + 0.7v = 0.45 (175 mL + v)
43.75 mL + 0.7v = 78.75 mL + 0.45v
0.25v = 35 mL
v = 140 mL

Step-by-step explanation:
the numerator of a fraction x/y is 2 less than the denominator. If 3 is added to both the numerator and denominator, then the sum of the new fraction and the original fraction is 53/35 find the quadratic equation.
Answer:
Step-by-step explanation:
Fraction :x/y
numerator x = y - 2
Now the fraction can be written as: (y-2)/y
3 is added to both denominator and numerator.
After adding 3, the new fraction = [tex]\frac{y-2 +3 }{y + 3 } = \frac{y+ 1 }{y +3}[/tex]
The sum of the new fraction and the original fraction is 53/35
[tex]\frac{y+1}{y+3} + \frac{y-2}{y} = \frac{53}{35}\\\\\frac{(y+1)*y}{(y+3)*y}+\frac{(y-2)*(y+3)}{y(y+3)}=\frac{53}{35}\\\\\frac{y^{2}+y}{y^{2}+3y}+\frac{y^{2}+y-6}{y^{2}+3y}=\frac{53}{35}\\\\\frac{y^{2}+y+y^{2}+y-6}{y^{2}+3y}=\frac{53}{35}\\\\\frac{2y^{2} + 2y - 6}{y^{2}+3y}=\frac{53}{35}\\\\[/tex]
35*(2y² + 2y - 6) = 53 *(y² + 3y)
35*2y² + 2y * 35 - 6*35 = 53 *y² + 53*3y
70y² + 70y - 210 = 53y² + 159y
70y² + 70y - 210 - 53y² - 159y = 0
70y² - 53y² + 70y - 159y - 210 = 0
17y² - 89y - 210 = 0
Answer:
17y^2 - 89y - 210 = 0
Step-by-step explanation:
Original fraction: x/y
The numerator is 2 les than the denominator, x = y - 2
Original fraction: (y - 2)/y
New fraction:
Add 3 to the numerator and denominator of the original fraction:
(y - 2 + 3)/(y + 3) = (y + 1)/(y + 3)
Add the new fraction and old fraction and get 53/35.
(y - 2)/y + (y + 1)/(y + 3) = 53/35
35y(y + 3)[(y - 2)/y] + 35y(y + 3)[(y + 1)/(y + 3)] = 35y(y + 3)(53/35)
35(y + 3)(y - 2) + 35y(y + 1) = 53(y^2 + 3y)
35(y^2 + y - 6) + 35(y^2 + y) = 53y^2 + 159y
17y^2 - 89y - 210 = 0

What is always true about a linear pair?
O A. The sum of angle measures is 180°.
B. Each angle measure is the same.
O C. The sum of angle measures is 90°.
D. The sum of angle measures is 360°.
Answer:
O A. The sum of angle measures is 180°.
Step-by-step explanation:
A linear pair of angles are supplementary.
They must add up to 180°.
Linear pairs also would form a straight angle. A straight angle is 180°.

What is the intermediate step in the form (x + a)2 = b as a result of
completing the square for the following equation?
-3x2 - 36x = 300
Answer:
we need to add a²=6² to both sides of [tex]x^2+12x+6^2=-100+6^2[/tex] in order to rewrite in the form [tex]\left(x\:+\:a\right)^2\:=\:b[/tex].
Step-by-step explanation:
Given the equation
[tex]-3x^2-36x=300[/tex]
First of all, we need to divide both sides by -3 to simplify it
i.e.
[tex]\frac{-3x^2-36x}{-3}=\frac{300}{-3}[/tex]
[tex]x^2+12x=-100[/tex]
In order to rewrite in the form [tex]\left(x\:+\:a\right)^2\:=\:b[/tex], we need to add a²=6² to both sides
[tex]x^2+12x+6^2=-100+6^2[/tex]
so
[tex]\left(x+6\right)^2=-64[/tex]
Therefore, we need to add a²=6² to both sides of [tex]x^2+12x+6^2=-100+6^2[/tex] in order to rewrite in the form [tex]\left(x\:+\:a\right)^2\:=\:b[/tex].

Two lines are parallel, but are not the same line. Which of the following is not true of the lines? A. The slopes are the same. B. The lines have no points in common. C. The y-intercepts are not the same. D. The lines must have a positive slope. Please select the best answer from the choices provided A B C D
Answer:
D
Step-by-step explanation:
Parallel lines must have the same slope. They could have points in common. If the y-intercepts were the same, taking into consideration the fact that the slopes have to be the same, it would be the same line and as the question directs, they are not. Parallel lines can have negative slope, as long as their slopes are equal.
