Answer:
In order to calculate the sample deviation we need to calculate the mean given by:
And replacing we got:
And the standard deviation can be calculated with this formula:
And replacing we got:
Step-by-step explanation:
For this case we have the following data given:
281, 269, 259, 265, 256, 259, 266
The range is defined as:
And if we replace we got:
In order to calculate the sample deviation we need to calculate the mean given by:
And replacing we got:

And replacing we got:
Answer:
Step-by-step explanation:
Let base be b, height be h
h = 7+b or we can say that b = h -7
A = 15 cm²
General formula for area of a triangle
A = b · h
Substitute what we know to find the height h
15 = (h-7) · h
15 = h² -7h
0 = h²-7h -15
h = (7 ±√49 + 4·1·15)/2
h = (7 ±√109)/2
h ≈ -1.72 reject this solution because height cannot be negative
h ≈ 8.72 cm
The benefits are 2, 3, 4, 6 & 7. The benefits listed are more on the business side in house purchasing. It is said that it is a good form of investment. You can stop paying for rents and have a sense of ownership, eventually, you can rent out or sell your house for higher values. Nowadays, owning a house is also quite easier due from easily accessible loans.
Answer:
<u>Use 2 points from he table to find the slope of f(x):</u>
<u>The slope is:</u>
The y - intercept is b = -1 according to point (0, -1).
<h3>Part A</h3>
<u>The lines are:</u>
- f(x) = 8x - 1
- g(x) = 3x - 2
The f(x) has greater slope since 8 > 3 and greater y-intercept since -1 > - 2.
<h3>Part B</h3>
See above
