Statement first there was a ten-year age gap between the oldest and youngest students in 1990.and statement fourth are correct
What are population and sample?It is defined as the group of data having the same entity which is related to some problems. The sample is a subset of the population, it is a part of the population.
We have:
Survey data involving two random samples of students at law school are shown. The surveys were taken, comparing the age of students in 1900 to the age of students in 2014.
The statements that are true about the two samples of students:
In 1990, there was a 10-year age difference between the oldest and youngest students.In 2014, the median age of students was greater than the median age in 1990.Thus, statement first there was a ten-year age gap between the oldest and youngest students in 1990.and statement fourth are correct

Answer:
y-intercept: [tex](0,-\frac{5}{2} )[/tex]
x-intercept: [tex](-2,0)[/tex]
Step-by-step explanation:
Hi there!
Important things to note:
the y-intercept occurs when x=0the x-intercept occurs when y=01) Find the y-intercept
[tex]-5x-4y=10[/tex]
Substitute x with 0
[tex]-5(0)-4y=10\\0-4y=10\\-4y=10[/tex]
Divide both sides by -4
[tex]\frac{-4y}{-4} =\frac{10}{-4} \\y=-\frac{5}{2}[/tex]
Therefore, the y-intercept is [tex]-\frac{5}{2}[/tex]. When written in (x,y) form, x will always be 0 while y is the y-intercept:
[tex](0,-\frac{5}{2} )[/tex]
2) Find the x-intercept
[tex]-5x-4y=10[/tex]
Substitute y with 0
[tex]-5x-4(0)=10\\-5x-0=10\\-5x=10[/tex]
Divide both sides by -5
[tex]-5x=10\\\frac{-5x}{-5}= \frac{10}{-5} \\x=-2[/tex]
Therefore, the x-intercept is -2. When written in (x,y) form, x will always be the x-intercept while y is always 0:
[tex](-2,0)[/tex]

make a flow chart showing that the two triangles are congruent. NO LINKS!
Answer:
Step-by-step explanation:
I take it the unmarked angle on the top triangle should be Q
The way the triangles are marked the following are the statements.
<Q = < X Given
RQ = XZ Given
XY = PQ Given
Is the angle included between the two given sides?
If yes then the Two Triangles are congruent by SAS
If no then the Two Triangles cannot be conclusively known to be congruent.
I have to leave you to figure out the flow chart symbols. I have no way of showing this as a flow chart if it is a computer program flow chart.

Write the point -slope form of the equation of the line (-2,5), slope =6
Answer:
y - 5 = 6(x + 2)
Step-by-step explanation:
The equation of a line in point- slope form is
y - b = m(x - a)
where m is the slope and (a, b) a point on the line
Here m = 6 and (a, b) = (- 2, 5) , then
y - 5 = 6(x - (- 2)) , that is
y - 5 = 6(x + 2)
Complete the function table for each equation
Answer:
y=-32, 0, -16, -4, 16
Step-by-step explanation:
y=4(-6)-8= -32
y=4(2)-8 = 0
y=4(-2)-8 = -16
y=4(1) -8 = -4
y=4(6) -8= 16
For the given equation of the line, the complete table is attached below.
Use the concept of the equation of line defined as:
A line has length but no width, making it a one-dimensional figure. A line is made up of a collection of points that can be stretched indefinitely in opposing directions. Two points in a two-dimensional plane determine it.
The given equation of a line is,
y = 4x - x
To complete the table:
Put x = -6 in this equation,
y = (-4)(-6) - 8
y = 16
Put x = 2 in the equation,
y = (-4)(2) - 8
y = -16
Put x = -2 in the equation,
y = (-4)(-2) - 8
y = 0
Put x = 1 in the equation,
y = (-4)(1) - 8
y = -12
Put x = 6 in the equation,
y = (-4)(6) - 8
y = -32
The complete table is attached below.

From the equation, find the axis of symmetry of the parabola. y = 3 x squared minus 12 x + 11 a. x = negative 2 c. x = 1 b. x = 2 d. x = negative 1 Please select the best answer from the choices provided A B C D
Answer:
the axis of symmetry would be: b. x=2
The equation of the axis of symmetry of the parabola will be x = 2. Then the correct option is B.
What is the equation of the parabola?Let the point (h, k) be the vertex of the parabola and a be the leading coefficient.
Then the equation of the parabola will be given as,
y = a(x - h)² + k
The equation is given below.
y = 3x² - 12x + 11
Convert the equation into a vertex form. Then we have
y = 3x² - 12x + 11
y = 3x² - 12x + 12 - 1
y = 3(x² - 4x + 4) - 1
y = 3(x - 2)² - 1
The equation of the axis of symmetry of the parabola is given as,
x - 2 = 0
x = 2
The equation of the axis of symmetry of the parabola will be x = 2. Then the correct option is B.

Kyle is buying a $220 bicycle if the bicycle is on sale for 35% off how much will he save
Answer:
$77
Step-by-step explanation:
Okay so first, we know that the bicycle is 220 dollars. So we got to multiply that to the percent. We can't muiltiply it into the percent yet so we turn that percent into 0.35
220 * 0.35
This equals to 77. That's the answer but it's not that simple, cause we aren't finished!
So we know that 35 percent of 220 is 77 dollars. So subtract that to 220!
220 - 77
This is equal to 143. Now how much will he save? He will save 220 - 143, which is 77! That's how we know the answer! I'm sure this is correct, if itsn't please comment! Have a great day!
Answer:
$143
Step-by-step explanation you wanna see how much 35% is out of 220
35% = 0.35
220 * 0.35 = 77 = discount
Now you want to see how much it will be when the discount is applied
220-77 = 143
The bicycle is $143 when discount is applied, you save $77

solve the inequality 3/5x +30>150
Answer:
Step-by-step explanation:
3/5x+30=150
We move all terms to the left:
3/5x+30-(150)=0
Domain of the equation: 5x!=0
x!=0/5
x!=0
x∈R
We add all the numbers together, and all the variables
3/5x-120=0
We multiply all the terms by the denominator
-120*5x+3=0
Wy multiply elements
-600x+3=0
We move all terms containing x to the left, all other terms to the right
-600x=-3
x=-3/-600
x=1/200
