Answer:
a) The table is in the attached file
b) P(X=1, Y =1) = P(X=1)P(Y=1)
c) 0.06
d) 0.19
Step-by-step explanation:
Check the attached files for the solutions and explanations for questions a to d
Volume of cone is (1/3)π r² h.
So since diameter is 18 inches, radius is 9 inches, right?
So just plug in values and calculate;
V = (1/3)·π·9²·14
= 378π
≈ 1187.52
Step-by-step explanation:
x+90+4x-75=180
add all the sides together and since its a triangle they equal to 180
Answer:
How far does Clare travel in one hour?
A: 36
How far does Clare travel in three hours?
A: 108
How far does Clare travel in 3.5 hours?
A: 126
Step-by-step explanation:
Find the Unit Value
72/2 = 36
Clare travels 36 miles per hour
Therefore, you must multiply the hours by the Unit travel time for the answers.
1 X 36 = 36
3 X 36 = 108
3.5 X 36 = 126
Answer:
Part 1) 
Part 2) 
Step-by-step explanation:
<u><em>The picture of the question in the attached figure</em></u>
Part 1) Find the area
we know that
The area of the shape is equal to the area of a quarter of circle minus the area of an isosceles right triangle
so

we have that the base and the height of triangle is equal to the radius of the circle

substitute

simplify
Factor 36

Part 2) Find the perimeter
The perimeter of the figure is equal to the circumference of a quarter of circle plus the hypotenuse of the right triangle
The circumference of a quarter of circle is equal to

substitute the given values

Applying the Pythagorean Theorem
The hypotenuse of right triangle is equal to

simplify

Find the perimeter

simplify
Factor 6
