64/109 ≈ 0.5872
Step-by-step explanation:
41 + 23 = 64 of the events have outcome E.
An additional 35 + 10 = 45 do not.
The probability of an outcome of E is 64 out of a total of 64+45 = 109 events.
P(E) = 64/109 ≈ 0.5872
Answer:
15°
Step-by-step explanation:
sum of exterior angles=360°
each angle=360/24=15°
b
20 ×n=360
n=360/20=18
18 sides
c.
(n-2)×180=174n
180n-174n=360
6 n=360
n=360/6=60
number of sides =60
75 cm, 100 centimeters is one meter. 15 times 100 divided by 20
Answer:
A right triangle is a triangle with one right angle 90 degree. The side opposite the right angle is called the "hypotenuse", and the other two sides are called the legs. The angles opposite the legs, by definition, are complementary.The Pythagorean Theorem states that in all right triangles, a^{2}+b^{2}=c^{2}.
