Answer:
0.3 probability that 
Step-by-step explanation:
The probability distribution is given in the table.
Probability that x <= -3
The values that are -3 or lower are -3 and -5. So

From the table:
. So

0.3 probability that 
Yo sup??
For our convenience let h=x+1
therefore
when x tends to -1, h tends to 0
hence we can rewrite it as

This inequality is of the form 1∞
We will now apply the formula

plugging in the values of g(x) and f(x)

express coth² as cosh²/sinh² and also write cosh-1 as 2sin²(h/2)
(by applying the property that cos2x=1-sin²x)
After this multiply the numerator and denominator with h² so that we can apply the property that

Now your equation will look like this.

We will now apply the result

where x=h²
we get

we now multiply the numerator and denominator with 4 so that we can say



Apply the limits and you will get


Hope this helps.
Answer:
106
Step-by-step explanation:
When the decimal is 5 or greater, we round up. When the decimal is less than 5, we round down. For example, 105.4 would be rounded down to 105 because 4<5

5)
x = 132 - 42
x = 90
Answer
90 degrees, right angle
6)
180 - 126 = 54
The other two are congruent so 54/2 = 27
Answer
27
7)
An exterior angle of a triangle is equal to the sum of the opposite interior angles
So
6x = 38 + 82
6x = 120
x = 20
Answer
20
8)
Sum of interior in a triangle = 180 degrees
So
2x - 3 + 23 + 128 = 180
2x + 148 = 180
2x = 32
x = 16
Answer
16
