A medical clinic asks all of its patients to complete a quick survey after each appointment. Patients are asked to rate their experience on a scale of 1 to 10, with 1 representing a very poor experience, and 10 representing an excellent experience. The surveys are separated into categories based on age. Then, each month, a random sample of 10 surveys are gathered from each age category. The results of this month's random samples of the 40-60 age group and the 60+ age group are shown below.
40 - 60 2 6 5 5 3 7 3 9 1 4
60+ 4 8 7 10 3 6 5 8 9 5
The mean rating of the 40-60 group is two points _____
than the mean rating of the 60+ group. This difference is about ______
the variability of either group.

Answer:
5 miles
Step-by-step explanation:
Time/speed/distance problems can be worked a number of ways. Here, we want to know the distance walked. We know the total time and the total distance and the two different speeds. So, we can use a variable to represent the value we want to know: w = distance walked (in miles).
The total time is 9:00 -6:50 = 2:10 = 2 1/6 hours = 13/6 hours.
The total time is the sum of times for the two parts of the trip: walking and riding.
walking time = walking distance/walking speed
= w/3
riding time = riding distance/riding speed
= (20-w)/30
The total time is that given above:
w/3 +(20-w)/30 = 13/6
10w +(20 -w) = 65 . . . . . . . . multiply by 30
9w = 45 . . . . . . . . . . . . subtract 20, collect terms
w = 5 . . . . . . . . . . . divide by 9

5364 minus 12.8 = 5351.2
The volume of this cylinder is 1751 cubic units. What is the volume of a cone that has the same base area and the sam height
Answer:
[tex]V_2 = 583.67[/tex]
Step-by-step explanation:
Given
Represent the volume of the cylinder with V1 and the cone with V2.
So:
[tex]V_1 = 1751[/tex]
Required
Find V2
The volume of a cylinder is:
[tex]V_1 = \pi r^2h[/tex]
Because the cone and the cylinder have the same base area and height, the volume of the cone is:
[tex]V_2 = \frac{1}{3}\pi r^2h[/tex]
Substitute [tex]V_1[/tex] for [tex]\pi r^2h[/tex].
[tex]V_2 = \frac{1}{3}\pi r^2h[/tex]
[tex]V_2 = \frac{1}{3}V_1[/tex]
Substitute 1751 for V1
[tex]V_2 = \frac{1}{3} * 1751[/tex]
[tex]V_2 = \frac{1* 1751}{3}[/tex]
[tex]V_2 = \frac{1751}{3}[/tex]
[tex]V_2 = 583.67[/tex]
The volume of the cone is 583.67 cubic units

Answer:
437.3 ft
Step-by-step explanation:
The angle of depression can be copied inside the triangle to the angle of elevation (at lower right). Then the side x can be seen to be adjacent to the angle.
The mnemonic SOH CAH TOA reminds you of the relations. Here, we have the hypotenuse and we want the adjacent angle. The relevant relation is ...
Cos = Adjacent/Hypotenuse
cos(29°) = x/(500 ft)
Multiplying by 500 ft gives ...
x = (500 ft)cos(29°)
x ≈ 437.3 ft
_____
Additional comment
You have posted a number of problems that make use of this geometry. They are all solved the same way:
a) identify the desired measure and the given measures
b) using SOH CAH TOA, identify the relation applicable to those measures
c) fill in the given values in the equation
d) solve for the unknown
You may need to make use of what you know about angles and triangles in order to relate given angles to ones you need to use.

how do you solve the system:
y+1=2x
5y+5=10x
Answer:
choose "infinitely more solutions"
Step-by-step explanation:
Let's solve this system by substitution method
y+1=2x
- 1 = - 1
y = 2x -1 <-- sbstitute this in the next equation
---------------------------------------------------------------------------------
5y+5 = 10x
5(2x -1) + 5 = 10x
10x -5 + 5 = 10x
10x + 0= 10x
- 10x = -10x
0 = 0 <-- infinitely more solutions
Answer:
5+5=10x
y=1×5+5=10x45×+=1+32=

Which graph is the solution to the following inequality
Step-by-step explanation:
-8x+5 > 21
Minus 5 from both sides
-8x > 16
Then divide 8 from both sides (also I am pretty sure the sign would change because you are dividing by a negative number)
x < -2
So the answer is x is less than or equal to -2
or C

Write an inequality that matches the graph.
A number line from zero to ten is shown. A ray extends to the left from a closed circle at six.
Answer:
[tex]x \leq 6[/tex]
Step-by-step explanation:
because the ray travels left, x has to be lower than 6, and since it is a closed circle, means that 6 is included in the answer, so x is less than or equal to 6.

An equation is shown below:
8(2x − 14) + 13 = 4x − 27
Part A: Write the steps you will use to solve the equation, and explain each step. (6 points)
Part B: What value of x makes the equation true? (4 points)
Explain the parts please and i will give brainliest the best best explained one.
Answer:
x = 6
Step-by-step explanation:
8(2x − 14) + 13 = 4x − 27
solve everything in parentheses
16x - 112 + 13 = 4x - 27
subtract 4x from each side of the equation
16x - 4x - 112 + 13 = 4x - 27 - 4x
reduce
12x - 112 + 13 = -27
combine those known numbers
12x - 99 = -27
add 99 tooth sides of the equation
12x - 99 + 99 = -27 + 99
reduce
12x = 72
divide both sides by 12
12x / 12 = 72 / 12
reduce
x = 6
