Answer:
Haha proofs are an interesting thing. Usually, nothing is to scale, which is why you can't measure anything. They are pretty annoying, but it helps to know why certain things are the way that they are and develop justification skills for higher level math.
Sorry to discourage you, but you're going to see "Justify" quite a lot in calculus and beyond which is basically a more informal version of a proof
you can never escape it tbh lol
Answer:
C XD
Step-by-step explanation:
The altitude of a triangle goes from the vertex (corner) to the opposite side. It must be perpendicular to the opposite side ( at a right angle)
XD is an altitude

3

A) 1
(B) 2
(C) 3
(D) 4
(E) 5
Mean is a measure of central tendency. It is the average of a set of numbers. It is determined by adding the numbers together and dividing it by the total number
Mean = sum of numbers / number of observation
sum of numbers = 3 x 7 = 21
Median is the number that is at the center or middle of a set of obervations
x + 9+ y = 21
x= lowest number
y = highest number
x + y = 21 - 9
x + y = 12
If x = 1 y = 11
if x = 2 y = 10
if x = 3 y = 9
if x = 4 y = 8
the first 3 are plausible and the median would still be 9 if x = 4, median would be 8
Answer:
0.9958
Step-by-step explanation:
P(being correct) = 1/4 = 0.25
Hence, p = 0.25
n = 19
P(x ≥ 1) = p(x = 1) + p(x = 2) +... + p(x = 19)
Using the binomial probability formula :
P(x =x) = nCx * p^x * (1 - p)^(n - x)
However, to save computation time, we could use a calculator :
Using a calculator,
P(x ≥ 1) = 0.99577
P(x ≥ 1) = 0.9958
B= 60
To find b you must do the pythagorean theorem because it is a right triangle
65^2 - 25^2=b^2
3600=b^2
60=b
x= 18
To find x you must know that a triangle is made up of 180 degrees.
x= 180-(72+90)
x=180-162
x=18
hope this helped :)
