Can you show me a picture of the problem?
Answer:
743.25m^2
Step-by-step explanation:
Area of triangle = 1/2bh
= 1/2 x 30 x 26
= 390
Area of semi circle = 1/2 πr^2
= 1/ 2 x 3.14 x 15 x15
=353.25m^2
= 390 + 353.25
= 743.25m^2
Answer:
92°
Step-by-step explanation:
The exterior angle is equal to the sum of the 2 opposite interior angles, that is
2x - 2 = x + 45 ( subtract x from both sides )
x - 2 = 45 ( add 2 to both sides )
x = 47
Then
exterior angle = 2x - 2 = 2(47) - 2 = 94 - 2 = 92°
Answer:
0.19975
Step-by-step explanation:
P = nCr pʳ qⁿ⁻ʳ
where n is the number of trials,
r is the number of successes,
p is the probability of success,
and q is the probability of failure (1−p).
Given:
n = 11
r = 9
p = 0.7
q = 0.3
Plugging in values:
P = ₁₁C₉ (0.7⁹) (0.3¹¹⁻⁹)
P = 0.19975
