Pleaseeeeee help me out quickkk solve for x
xxTIMURxx [149]

Answer:

x = 27.2

Step-by-step explanation:

Apply trigonometric function to solve for x.

Reference angle = 54°

Side length opposite to reference angle = 22

Hypotenuse = x

We would apply SOH:

Sin 54 = Opp/Hyp

Sin 54 = 22/x

x*sin 54 = 22

x = 22/sin 54

x = 27.1934955 ≈ 27.2 (nearest tenth)

Answer:
63 Degrees

Steps:
Use the Pythagorean Theorem to find the missing side.

a^2 + b^2 = c^2
c = SQRT(a^2 + b^2)

c = SQRT(81^2 + 41^2)
c = SQRT(8242)
c = 90.785

ASIN is the inverse of sine.

(c) what is the probability that at least one adult prefers milk chocolate to dark chocolate?
Schach [20]
Part A:

Given that 47% of adults prefer milk chocolate to dark chocolate, for a random sample of n = 4 adults, the probability that all four adults say that they prefer milk chocolate to dark chocolate is given by

P(4)=(0.47)^4=0.049



Part B:

The probability that exactly two of the four adults say they prefer milk chocolate to dark chocolate is given by

P(2)={ ^4C_2(0.47)^2(1-0.47)^2} \\  \\ =6(0.2209)(0.2809)=0.372



Part C:

The probability that at least one adult prefers milk chocolate to dark chocolate is given by

P(at \ least \ 1)=P(X\geq1) \\  \\ =P(1)+P(2)+P(3)+P(4) \\  \\ =1-P(0)=1-{ ^4C_0(0.47)^0(1-0.47)^4} \\  \\ =1-(0.53)^4=1-0.0789=0.921
