Answer:
16 questions
Step-by-step explanation:
12÷3/4
12×4/3
48/3=16
Triangle B can be proven congruent
if events X and Y are independent, then for intersection we multiply the probability
P(Y∩X) = P(Y) * P(X)
We know that
Now we replace P(Y) * P(X) for P(Y∩X)
Cancel out P(X)
So 
Like that
Now we replace P(X) * P(Y) for P(X∩Y)
Cancel out P(Y)
So 
P(Y | X) = P(Y) and P(X | Y) = P(X) are true
Answer:
B) 420
Step-by-step explanation:
V= lwh
l = 7
w = 5
h = 12
V = (7)(5)(12)
V = 420
Answer:
<h3>The answer is 60cm</h3>
Step-by-step explanation:
Perimeter of a rectangle = 2l + 2w
Area of rectangle = l × w
where
l is the length
w is the width
From the question
The length is twice its width is written as
l = 2w
Substitute this into the formula for finding the area of the rectangle
Area = 200 yd²
200 = 2w²
Divide both sides by 2
w² = 100
Find the square root of both sides
width = 10cm
Substitute this value into l = 2w
That's
l = 2(10)
length = 20cm
Perimeter of the rectangle is
2(20) + 2(10)
= 40 + 20
<h3>= 60cm</h3>
