Answer:
ax+b
Step-by-step explanation:
Answer:
x = 45
y = 45
z = 11.1
Step-by-step explanation:
Remark
The triangle is a right triangle. That means that it has 1 right angle.
It is also isosceles which means that the two legs that are not the hypotenuse are equal.
Result: z and 11.1 are equal z = 11.1
More remark
If the triangle is isosceles, that means that the angles that are not right angles must also be equal.
90 + x + y = 180
but x = y
90 + 2x = 180 Subtract 90
2x = 180 - 90 Divide by 2
2x/2 = 90/2
x = 45
Answer:
3y+5
Step-by-step explanation:
Combine the like terms
11y+2y-10y= 3y
12-6= +5
Answer:
a) Mean: 13.25
Variance: 11.02
b)
0 if x below than 7.5
is x in between 7.5 and 19
1 if x higher than 19.
Step-by-step explanation:
This is a problem in which we use the uniform probability distribution.
(a) What are the mean and variance of depth?
The mean is the midpoint of 7.5 and 19. So

The mean is 13.25
The variance is given by the following formula:

In which b and a are the limits of the interval. So 
So

The variance is 11.02.
(b) What is the cdf of depth?
The uniform probability distribution has a cummulative distribution function, of 0 if is below a,
for x in between a and b and 1 is x is greater than b.
So:
0 if x below than 7.5
is x in between 7.5 and 19
1 if x higher than 19.
