Find the mean of the following data set.
42, 45, 58, 63
52
42
47
Answers
Answer:
~49.9
Step-by-step explanation:
To get the mean, we must add all the numbers then divide by the amount of numbers there were.
42 + 45 + 58 + 63 + 52 + 42 + 47 = 349
Since we have 7 numbers we can do
349/7 ~ 49.9
Answer: 49.8 (50 if rounded to the nearest ones place)
Step-by-step explanation: First, let's put the number from greatest to least...and we also have to add all the numbers...
42 + 42 + 45 + 47 + 52 + 58 + 63 = 349
Lastly, we have to divide the total by how many numbers there are on the data set...there's 7
349 ÷ 7 = 49.8 (50 if rounded to the nearest ones place)
Therefore, the mean is 49.8 or 50, I hope this helps!

Since the radius is half of the diameter and we know that the diameter of the trashball is 4 in, we half the 4. So the radius of the trashball is 2 in.
Now plug everything in the formula.
2(3.14)(2) = 12.56.
The circumference of the trashball is 12.56 in.
Answer:
The circumference talks about the outside of the circle. So the formula for the circumference of a circle is 2πr (r stands for radius and π is pi. In this case we use 3.14 for pi).
Since the radius is half of the diameter and we know that the diameter of the trashball is 4 in, we half the 4. So the radius of the trashball is 2 in.
Now plug everything in the formula.
2(3.14)(2) = 12.56.
The circumference of the trashball is 12.56 in.

andre is traveling from jeffersonville to springfield. he plans to stop for a break when the distance he has traveled and the distance he has left to travel have a ratio of 3:7. where should andre stop for his break? jeffersonville, J (-15, 2). springfield, S (25, 17)
Answers
Answer:
Andre should stop at (-3 , 6.5)
Step-by-step explanation:
The change in x is from -15 to 25 which is 40 units. 40 x 3/10 = 12 which means Andre moves 12 units right starting from -15 so the x coordinate is -15+12 = -3
The change in y is from 2 to 17 which is 15 units. 15 x 3/10 = 4.5 which means Andre moves 4.5 units up starting from 2 so the y coordinate is 2+4.5 = 6.5.
Find the line parallel to y = -2x - 5
that includes the point (-1, 3).
Enter the y value of the point.

Answers
Using the point-slope form: y - y₁ = m(x - x₁)
Plug in the values: y - 3 = -2(x - (-1))
Simplify: y - 3 = -2(x + 1)
Now, we can find the y value of the point:
y - 3 = -2(-1 + 1)
y - 3 = 0
y = 3
So, the y value of the point is 3.

which graph represent the liner function y= 1/3 x -4?
Answers
Answer:
Graph 3
Step-by-step explanation:
equation: y = mx + b → y = 1/3x - 4
- m is the slope (slope = rise / run):
- b is the y intercept (when x = 0): -4
Graph 1 is incorrect because the y-intercept is 1.5 on this graph when the equation is -4
Graph 2 is incorrect because the slope is 3 / 1, the rise is 3 and the run is 1
the correct equation for this graph is y = 3x - 4
Graph 3 is correct because the slope is 1/3, the rise is 1 and the run is 3
and the y intercept is -4
Graph 4 is incorrect because the y-intercept is not even shown

The population of some native bees is declining at a rate of 9% per year. If there are 13200 bees in a hive now, how many will there be in 5 years time?
Answers
Answer:
There will be 7,260 bees in 5 years.
Step-by-step explanation:
9% per year=0.09(13200)=1188.
1,188 bees die a year.
1,188 times 5=5940
13200-5940=7260

The lateral surface area is the area of the sides, not including the top and bottom.
Assuming the 3×6 rectangles are the top and bottom, the lateral surface area is:
LA = 2×3 + 2×3 + 2×6 + 2×6
LA = 6 + 6 + 12 + 12
LA = 36
The total surface area is the lateral surface area plus the area of the top and bottom.
SA = 36 + 3×6 + 3×6
SA = 36 + 18 + 18
SA = 72

If we are given the equation of a line in this format:
y=mx+b
then it is quite simple to find the gradient and y-intercept.
In the format:
y=mx+b
the m represents the gradient (slope) and b represents the y-interpcept.
1) y=2x+3
gradient= 2
y-intercept= 3
2) y=x-5
gradient= 1
y-intercept= -5
3) y=-2x-4
gradient= -2
y-intercept= -4
4) y=5-x
gradient= -1
y-intercept= 5
5) y=3x+8
gradient= 3
y-intercept= 8
6) y= 1/4x+3
gradient= 1/4
y-intercept= 3
