The time in minutes for each of Sam's phone calls this week are shown in the list. {9, 15, 5, 7, 9, 12, 11, 4} Which statement is true regarding the duration of his calls? A. The median is greater than 10. B. The mean is less than 8. C. The range is less than 10. D. The mode is greater than 7.
Answers
Answer: The mode is greater than 7.
Step-by-step explanation:
The time in minutes are given as 9, 15, 5, 7, 9, 12, 11, 4. We can arrange them in ascending order and this will be:
= 4, 5, 7, 9, 9, 11, 12, 15
Mean = (4 + 5 + 7 + 9 + 9 + 11 + 12 + 15) / 8 = 9
Median = 9+9/2 = 18/2 = 9
Mode = 9
Range = 15 - 4 = 11
Therefore, the true statement are:
D. The mode is greater than 7.

B) 7/2
3) Which of the following zeros of the following quadratic function x2+14x+49?
A)-7
B)14
Answers
Answer:
1) A
3) A
Step-by-step explanation:
Solve using factoring or quadratic formula.
Solve the area of a trapezoid formula for the variable h: A = 1/2h(b1 + b2)
Note: In this formula, A = area, H = height, and b1 and b2 are the bases of the trapezoid.
Answers
The area of the trapezoid formula can be solved for the variable h as,
h = 2A / (b1 + b2)
Given the formula to find the area of the trapezoid.
A = 1/2 (b1 + b2) h
Here A is the area, h is the height and b1 and b2 are the bases of the trapezoid.
We have to get an equation for formula in h.
That is, we need to isolate h alone on one side and the other terms and variables on other side.
Multiplying whole equation with 2,
2A = (b1 + b2) h
Dividing whole by (b1 + b2),
h = 2A / (b1 + b2)
Hence the required equation is h = 2A / (b1 + b2).

Which number completes the system of linear inequalities represented by the graph? y > 2x – 2 and x + 4y >
Answers
we have y≥2x-2 ------> inequality A
The inequality A is the solid red line in the graph the solution of the inequality A is the shaded area above the solid red line x+4y≥?------> inequality B The inequality B is the solid blue line in the graph the solution of the inequality B is the shaded area above the solid blue line we know that the point (0,-3) lie on the line of the inequality B. substitute the values of x and y in the equation of the line
x+4y=c
0+4*(-3)=c
c=-12
so the answer is -12
The system of linear inequalities is:
y > 2x – 2 and x + 4y > -12.
What is inequality?It shows a relationship between two numbers or two expressions.
There are commonly used four inequalities:
Less than = <
Greater than = >
Less than and equal = ≤
Greater than and equal = ≥
We have,
When x = 0, y = 2(0) – 2 = -2.
So the point (0, -2) is on the line.
When x = 2, y = 2(2) – 2 = 2.
So point (2, 2) is on the line.
Plotting these two points and drawing a line through them gives us the graph of y = 2x – 2.
Next, let's graph x + 4y = -12 by solving for y:
x + 4y = -12
4y = -x - 12
y = (-1/4)x - 3
Again, we can plot two points on the line.
When x = 0, y = -3, giving us the point (0, -3).
When x = -4, y = -2, giving us the point (-4, -2).
Plotting these points and drawing a line through them gives us the graph of x + 4y = -12.
Thus,
The solution to the system of inequalities is the shaded region where the two graphs intersect and y > 2x – 2.
This region is shown in the attached image.

Step-by-step explanation:
It's a triangle, so we know that the sum of angles is 180deg
x + (2x - 9) + (2x + 4) = 180
5x - 5 = 180
5x = 185
x = 37
Measure of angle A = (2*37 - 9)deg = 65deg
Measure of angle B = (2*37 + 4)deg = 78deg

D) is the correct answer
Step-by-step explanation:
To define a function, so one x can only corresponding to one y.
Then for A) we have x = -5, but y can be 1 and 4, so it is to a function,
for B) x =1, y = -1 or -4, so not. For C) x =0, y = -3 or 0, so wrong. Then left with D) which each x only corresponding to one y, so D) is correct.

How many solutions does the equation 8x + 38 = -3(-6 - 4x) has?
Answers
Answer:
Step-by-step explanation:
8x + 38 = -3(-6 - 4x)
8x + 38 = -3(-4x - 6)
8x + 38 = -3 (-4x - 6)
8x + 38 = 12x + 18
8x +38 = 12x + 18
8x + 38 - 38 = 12x + 18 - 38
8x + 38 - 38 = 12x + 18 - 38
8x = 12x + 18 - 38
8x= 12x - 20
8x = 12x - 20
8x - 12x = 12x - 20 - 12x
8x - 12x = 12x - 20 - 12x
-4x = 12x - 20 -12x
-4x = 12x - 20 -12x
-4x = - 20
-4x = -20
