Answer:
52
Step-by-step explanation:
S(blue) = S(Whole) - S(cut part)
S(blue) = 7*11 - 5*5 = 77 - 25 = 52
Answer: 165
Step-by-step explanation: To evaluate this expression, we simply plug the value of the variable into the expression and solve.
So here, since <em>n</em> is equal to 15, we have 150 + (15) which simplifies to 165.
Answer:
Let X = score of final exam.
X~normal(23, 16)
(a)
percentage of score between 19 and 27
= P(19 < X < 27)
= P((19-23) / sqrt(16) < Z < (27 - 23) / sqrt(16))
= P(-1 < Z < 1)
= 1 - P(Z <= -1) - P(Z >= 1)
= 1 - P(Z >= 1) - P(Z >= 1)
= 1 - 2*P(Z >= 1)
= 1 - 2(0.1587)
= 0.6826
= 68.26%
According to Normal Distribution Table
P(Z>=1) = 1 - P(Z<1) = 1-0.8413
So the final percentage is 68.26%
This is what you're looking for if I'm not mistaken
sin²x + cos²x = 1
So:
sin²x = 1 - cos²x
∴ sin²x * cos²x = (1 - cos²x) * cos²x
= cos²x.(1 - cos²x)
(= cos²x - cos⁴x)
Both angles are congruent and since opposite angles of a trapezoid = 180, s and t equal 108.
