Many golfers wear wrist bracelets containing magnets because they claim the magnets improve balance and the length of shots played off the tee. A golfer would like to determine if the claim has merit and proposes two methods for collecting data. Method 1: As golfers approach the first tee, give some golfers wrist bracelets with magnets and some golfers wrist bracelets without magnets. During the round of golf, keep track of the length of the golfers’ shots. Method 2: Contact golfers who have purchased wrist bracelets with magnets and ask them to provide information about their shot length. Which statement about these methods is true? Method 1 is an observational study because it does not attempt to influence responses. Method 2 is an observational study because it does not attempt to influence responses. Method 2 is an observational study because it could include golfers from many golf courses. Both methods are observational studies because they both collect information about shot length.

4+3(x+2)=12
Plz answer
Answer: x = 2/3
Step-by-step explanation:
Let's solve your equation step-by-step.
4+3(x+2)=12
Step 1: Simplify both sides of the equation.
4+3(x+2)=12
4+(3)(x)+(3)(2)=12(Distribute)
4+3x+6=12
(3x)+(4+6)=12(Combine Like Terms)
3x+10=12
3x+10=12
Step 2: Subtract 10 from both sides.
3x+10−10=12−10
3x=2
Step 3: Divide both sides by 3.
3x/3 = 2/3
ANSWER: x = 2/3

Answer:
the lines are perpendicular
Step-by-step explanation:
When both equations are written in standard form, they are ...
y -3x = 5
3y +x = 2
The coefficients in one of these equations are swapped, and one is negated, relative to the coefficients in the other equation. This means the lines are perpendicular (their slopes are opposite reciprocals).
A graph confirms this relationship.

The relation ((6, 8), (7, 10), (7, 12), (8, 16),
(10, 16)} is not a function. Which x-value has
more than one y-value associated with it?
Record your answer on the grid provided.
Answer:
x = 7 is repeated twice.
Hence, there is NO MORE unique input. We can not have repeated inputs.
Thus, the relation is NOT a function.
Step-by-step explanation:
Given the relation
{(6, 8), (7, 10), (7, 12), (8, 16), (10, 16)}We know that a relation is a function that has only one output for any unique input.
As the inputs or x-values of the relations are:
at x = 6, y = 8
at x = 7, y = 10
at x = 7, y = 12
at x = 8, y = 16
at x = 10, y = 16
If we closely observe, we can check that there is a repetition of x values.
i.e. x = 7 is repeated twice.
Hence, there is NO MORE unique input. We can not have repeated inputs.
Thus, the relation is NOT a function.
i have to find the mean and range of this data set and show work.
data set: 49,50,52,58,61,63,66,67,67,68
Answer:
61 is the mean and the range is 19
Step-by-step explanation:
trust
Mean = [tex]60.1[/tex] and Range = [tex]19[/tex] for the given set of data.
What is Mean?
"Mean is the average set of all the given values."
What is Range?"Range is the difference between highest and the lowest value."
Formula
Mean = [tex]\frac{Sum of all the observations}{Total number of observations}[/tex]
Therefore, Mean = [tex]\frac{49 + 50 +52 +58 +61 +63 +66 +67 +67 +68}{10}[/tex]
= [tex]\frac{601}{10}[/tex]
= [tex]60.1[/tex]
Range = Max (x) - Min (x)
= [tex]68 - 49[/tex]
= [tex]19[/tex]
Hence, the Mean = [tex]60.1[/tex] and Range = [tex]19[/tex] for the given data set.

A road crew uses the triangles shown in the diagram to
measure the width of a sinkhole across a highway from a safe
distance away. How wide is the sinkhole?
Answer:
18 ft
Step-by-step explanation:
Both triangles shown are congruent.
By the concept of transversal lines and vertically opposite angles, we conclude that the width of the sinkhole is 18 feet.
What is a transversal?We know when a transversal intersects two parallel lines at two distinct points,
Two pairs of interior and alternate angles are formed such that the measure of interior angles are same and the measure of alternate angles is also the same.
We know when a transversal intersects a parallel line vertically opposite angles are equal and we also know that sides opposite to similar angles have the same length.
∴ The width of the sinkhole is also 18 feet.

Grant has $58 in a savings account. He plans on depositing $30 into the
account each month and not taking any money out of the account. Which
function rule will give the total amount T that he has in the account
after n months?
Answer
I believe it is the first answer
Step-by-step explanation:
You would have to multiply 30 by however many months he deposits money to find how much he has in he account at that time
Hope this helps
The function rule of the total amount T in the account after n months is
T = 30n + 58.
Option A is the correct answer.
What is an expression?An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.
Example: 2 + 3x + 4y = 7 is an expression.
We have,
Amount in the account = $58
Amount deposited each month = $30
The total amount after n months.
T = 58 + 30n
Thus,
The T = 30n + 58 is the total amount in the account after n months.

OB. 840 units2
O C. 480 units2
O D. 420 units2
Answer:
480 units^2
Step-by-step explanation:
5 * 12 = 60
13 * 14 = 182
12 *14 = 168
5 * 14 = 70
480
The surface area of the given prism will be 480 square units so the correct answer is option C.
What is surface area?The space occupied by any two-dimensional figure in a plane is called the area. The area of the outer surface of any body is called the surface area.
The triangular prism is having 6 surfaces so the surface area will be the sum of the area of all the sides of the prism.
The area of all the sides of the prism will be calculated as follows:-
5 x 12 = 60
13 x 14 = 182
12 x 14 = 168
5 x 14 = 70
The total surface area of the prims will be:-
SA of prism = 60 + 182 + 168 + 70 = 480 square units
Therefore the surface area of the given prism will be 480 square units so the correct answer is option C.

You would need to get all the numbers on one side and all the variables on the other side.
-48t + 2 -2 ≤ -71t + 14 -2 → -48t ≤ -71t + 12
