the mean is calculated as
mean = [tex]\frac{sum}{count}[/tex]
this year's mean = [tex]\frac{7+3.3+2}{3}[/tex] = [tex]\frac{12.3}{3}[/tex] = 4.1
last year's mean = [tex]\frac{5.3+1.6+2.4}{3}[/tex] = [tex]\frac{9.3}{3}[/tex] = 3.1

What is the volume of a sphere with a radius of 9.1 ft, rounded to the nearest tenth of a cubic foot?
The volume of the sphere with a radius of 9.1ft is 3256.55cubic feet.
We have given that, the radius of the sphere is 9.1ft.
We have to determine the volume of the sphere
What is the formula for the volume of the sphere?The volume of the sphere is given by
[tex]V=\frac{4}{3}\pi r^3[/tex]
r is the radius of the sphere
V- is the volume of the sphere
So use the given value in the formula so that,
[tex]V=\frac{4}{3}\pi (9.1)^3[/tex]
[tex]V=3156.55082 ft^3[/tex]
Therefore the volume of the sphere with a radius of 9.1ft is 3256.55cubic feet.

Which point is located at - 1/6
Answer:
Point C
Step-by-step explanation:
it is negative, so we can already eliminate points A and B so which leaves us with C and D. It is a fraction that is greater than -1 so that eliminates point D, so the remaining point is our final answer.
Answer:
Point C
Step-by-step explanation:
Step 1: What point is located at -1/6
We can see that the arrow pointing up showcases us going positive and the arrow pointing down showcases us going negative. 0 gives us the middle point between negatives and positives. We can see that there are 6 ticks between each whole number. Therefore, if we go 1/6 of a tick down in the negative direction we would get point C.

Answer:
The answer is y= -2
Step-by-step explanation:
(Arrange according to the like terms first)
5y-y+42= 34

Two chords intersect within a circle to form an angle whose measure is 53 degrees. If the intercepted arcs are represented by 3x + 3 and 10x -14, find the measure of the LARGER of these two arcs.
A. 106
B. 76
C. 9
D. 30
Answer:
76degrees
Step-by-step explanation:
Using the theorem which states that the vertex of the angle inside a circle is half the sum of the measured intercepted arcs. Hence;
Angle at the vertex = 53 degrees
Half the sum of intercepted arcs = 1/2(3x+3+10x-14)
Half the sum of intercepted arcs = 1/2(13x-11)
Equating to the vertex to find x
1/2(13x-11) = 53
13x - 11 = 2 * 53
13x - 11 = 106
13x = 106 + 11
13x = 117
x = 117/13
x = 9
For the arc 3x + 3
= 3(9) + 3
= 27 + 3
= 30degrees
For the arc 10x - 14
= 10(9) - 14
= 90 - 14
= 76degrees
Hence the measure of the larger of the two arcs is 76degrees

Answer:
z = -1.8, y = 10.2
Step-by-step explanation:
- 2z -2y = -24 (EQ 1)
3z - 2y = -33 (EQ 2)
Change one of the equations to it's opposite (Turning a negative number to a positive/or the other way around)
Let's target the equation that can leave us with the simplest question to solve
-2z + -2y = -24
-3z + 2y = 33
-5z = 9
(Dividing and switching the negative sign over)
z = -1.8
Plug in Z to solve for y.
-2(-1.8) - 2y = -24
3.6 - 2y = -24
-2y = -20.4
y = 10.4

If one end of a line segment is (4, 4) and midpoint is (-2,2), find the co-ordinates of the other end.
Answer:
-8,0
Step-by-step explanation:
From one end of a segment to the midpoint, it takes -6x to get to the midpoint. Based on that, you can go another 6 over the y graph and get -8 for x.
For y, the segment goes from 4 to 2 (a -2 over the x graph). you can infer then that the other end will be 0.
Find the value of x to the nearest tenth.
Answer:
x ≈ 16.2
Step-by-step explanation:
tan56° = [tex]\frac{24}{x}[/tex] ( multiply both sides by x )
x × tan56° = 24 ( divide both sides by tan56° )
x = [tex]\frac{24}{tan56}[/tex] ≈ 16.2 ( to the nearest tenth )
A hurricane wiped out 40% of the wild rats in a coastal city. Then, a disease spread through stagnant water killing 20% of the rats that survived the hurricane. What percentage of the original population of rats is left after these 2 events
After the hurricane and the disease, 48% of the original population of rats is left.
We have,
After the hurricane, 40% of the rats were wiped out, which means
100% - 40% = 60% of the rats survived.
Then, after the disease spread through stagnant water, 20% of the remaining rats were killed.
This means 100% - 20% = 80% of the rats that survived the hurricane are still left.
To find the percentage of the original population of rats that is left after both events, we multiply the percentages:
Percentage left = 60% * 80% = 0.6 * 0.8 = 0.48
Finally, we convert the decimal value back to a percentage:
Percentage left = 0.48 * 100% = 48%
Therefore,
After the hurricane and the disease, 48% of the original population of rats is left.

x-y=-3
-8x+y=45
Answer:
x = 17, y = 28
Step-by-step explanation:
1. Isolate for x in "x - y = -3, -8":
x - y+y = -3, -8+y
x = -11 + y
2. Substitute "x = -11 + y" in for x in the second expression:
-11 + y + y = 45
3. Simplify:
-11 + 2y = 45
4. Isolate y:
-11+11 +2y = 45+11
2y = 56
[tex]\frac{2y}{2} = \frac{56}{2}[/tex]
y = 28
5. Substitute the new y-value into the first equation:
x = -11 + 28
x = 17
