Answer: 120
Step-by-step explanation:
AP.EX
The estimate obtained from a sample of 120 is likely to be closest to the actual parameter value of a population
In sampling; the higher the sample size, the higher the estimate cam be closer to the actual parameter
From the list of given options;
The sample size 120 has the highest chance to be close to the actual parameter value
This is so because, 120 is greater than other sample sizes

If ben completes 1/4 of his book report in 5/6 of an hour how much of the book report does ben complete per hour?
Answer: Ben completes 3/10 of his book report per hour
Step-by-step explanation:
Ben completes 1/4 of his book report in 5/6 of an hour
5/6 of an hour = 5/ 6 x 60 = 50 minutes
Therefore in 1 hour, which is = 60 minutes he completes
(1/4 x 60 minutes)/ 50 minutes
= 15/ 50
= 3/10 of his book report.

L is in the interior of ∠JKM. If m∠JKL=56.4° and m∠JKM=82.5°, what is m∠LKM?
The measure of angle ∠LKM is m∠JKL=56.4° and m∠JKM=82.5° is 26.1 degrees
The point where two lines meet or intersect is known as an angle.
If L is in the interior of ∠JKM, then:
∠JKL + ∠LKM = ∠JKM
Given the following parameters
m∠JKL=56.4° and m∠JKM=82.5°
Required angle
m∠LKM
From the expression above:
m∠LKM = ∠JKM - ∠JKL
m∠LKM = 82.5 - 56.4
m∠LKM = 26.1 degrees
Hence the measure of angle ∠LKM is m∠JKL=56.4° and m∠JKM=82.5° is 26.1 degrees

The expression that has a term with a coefficient of 6 is бу.
Option A is the correct answer.
What is an expression?An expression contains one or more terms with addition, subtraction, multiplication, and division.
We always combine the like terms in an expression when we simplify.
We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.
Example:
1 + 3x + 4y = 7 is an expression.com
3 + 4 is an expression.
2 x 4 + 6 x 7 – 9 is an expression.
33 + 77 – 88 is an expression.
We have,
The term "coefficient" refers to the numerical factor that is multiplied by a variable or variables in a term.
Out of the given expressions, only one has a term with a coefficient of 6, which is:

Which correctly explains the number of solutions of the following system of linear
equations?
- 3x + 3y = 12
y = x + 4
А The graphs of the equations are parallel lines because they have the same slope
but different y-intercepts. The system has no solution.
B The graphs of the equations are lines that intersect at one point because the
equations have the same slope but different y-intercepts. The system has
exactly one solution.
с
The graphs of the equations are lines that intersect at one point because the
equations have the same slope and same y-intercept. The system has exactly
one solution.
D The graphs of the equations are the same line because the equations have the
same slope and same y-intercept. The system has infinitely many solutions.
Answer:
D I dont know if im right though
Step-by-step explanation:
The system of equations are same and graphs of the equations are the same line because the equations have the same slope and same y-intercept. The system has infinitely many solutions.
What is an Equation of a line?The equation of a line is expressed as y = mx + b where m is the slope and b is the y-intercept
And y - y₁ = m ( x - x₁ )
y = y-coordinate of second point
y₁ = y-coordinate of point one
m = slope
x = x-coordinate of second point
x₁ = x-coordinate of point one
The slope m = ( y₂ - y₁ ) / ( x₂ - x₁ )
Given data ,
Let the equation of line be represented as A
Now , the value of A is
The first equation is -3x + 3y = 12 be equation (1)
y = x + 4 be equation (2)
Adding 3x on both sides , we get
3y = 3x + 12
Divide by 3 on both sides , we get
y = x + 4 be equation (3)
So , the equation ( 2 ) is same as equation ( 3 )
Now , the slope of the equation is m = 1 and the y intercept is b = 4
Hence , the equations have infinite solutions

A scuba diver descends 80 feet, rises 25 feet, descends 12 feet, and then rises 52 feet where he will do a safety stop for five minutes before surfacing. At what depth did he do his safety stop?
Answer:
15 ft
Step-by-step explanation:
At 15 feet below the surface, the scuba diver did his safety stop.
What is the surface?The surface is the common region between two different mediums. Here in the question surface is the common region between seawater and above seawater.
Let us denote the values of descending by negative sign and rising by positive sign and we sum up all the values together.
∴ [ - 80 + 25 + (-12) + 52 ] feet.
= (-80 + 25 - 12 + 52) feet.
= - 15 feet.

Noah and Lin are marketing paper cones to hold popcorn to hand out at parent math night. They want the cones to hold 9 cubic inches of popcorn. What are two different possible values for height h and radius r for the cones?
if h=3, then r=
if r=2, then h=
Answer: r = 1.69 inches
h = 2.15 inches
Step-by-step explanation: Volume of a solid is the amount of space contained within a solid.
Volume of a cone is directly proportional to radius and height:
[tex]V=\frac{1}{3}\pi r^{2}h[/tex]
They want the cones to hold the same volume of 9 cubic inches.
If height is 3:
[tex]9=\frac{1}{3}\pi r^{2}3[/tex]
[tex]\pi r^{2}=9[/tex]
[tex]r^{2}=2.864[/tex]
r = 1.69 inches
When height is 3, radius is 1.69 inches for a cone to have 9 cubic inches of volume.
If radius is 2:
[tex]9=\frac{1}{3}\pi (2)^{2}h[/tex]
[tex]h=\frac{9(3)}{4 \pi}[/tex]
h = 2.15 inches
If radius is 2 inches, height of the cone is 2.15 inches.
