Answer:
87.5
you need to add all the numbers and the divide it by the sum of values
Answer:
B
Step-by-step explanation:
When it's parallel that means it has the same slope. The slope of this equation is 1/2 therefore the answer is B
Answer:
Sample
Step-by-step explanation:
The term that represents the description in the question is called sample.
Take for instance:
- 40 students selected from a class of 100
- 1000 people selected from a population of 100000
In the above descriptions:
40 and 1000 represent the samples while 100 and 100000 represent the populations, respectively.
Another example is when 10 cats are picked from an animal farm in order to study their eating pattern.
All these and many more represent sample.
Answer: 3528.25
Step-by-step explanation:Make a sideview sketch
you should have 2 triangles, one right-angled containing the height and a scalene triangle with angles 24° , 153° (the supplement of 27°) and 3°
the side opposite the 3° angle is 1000
by let the side opposite the 24° be x, (also the hypotenuse of the right-angled triangle)
x/sin24 = 1000/sin3
x = 1000sin24/sin3
let the height of the mountain be h
sin 27 = h/x
h = x sin27 = (1000sin24/sin3)(sin27)
= 3528.25
The question is asking how many combinations of two people can be made from a group of ten people.
Using the formula C(10,2) = 10!/(2! x (10 - 2)! = 10!/(2! x 8!) = 45 handshakes.
A simple way to prove this is each person shakes the hand of 9 other people
10 x 9 = 90 but this counts every handshake from the view of both people involved.
The actual number of handshakes is therefore 90 / 2 = 45
