Fofino [41]

The probability of senior citizens suffer from sleep disorders is

P(A)=0.91

The probability of senior citizens suffer from anxiety is,0.09.

P(B)=0.09

The probability of seniors suffer from both sleep disorders and anxiety is,

P(A\cap B)=0.06

a. The probability that a senior citizen suffers from anxiety, given that he or she has a

sleep disorder.

P(A|B)=\frac{P(A\cap B)}{P(B)}P(A|B)=\frac{0.06}{0.09}P(A|B)=0.67

What is the length of side BC? What is the length of side GH?
almond37 [142]
In this situation you would have to use ratios to figure it out.
AD over EH or 24/16 that would be equal to 1.5
This would show that BC over GF is also equal to 1.5.
6/4 is equal to 1.5.
Side length BC is 6

Hello! We will be using the Pythagorean theorum, where a² + b² = c². C is the clanted part of the triangle, and 13² is 169. a = 12, and we are looking for the value of b. 12² is 144. Let's subtract to find b. 169 - 144 is 25. Now, let's find the square root of 25 to find the length. √25 is 5. There. b = 5. The side length of side b is 5. The correct answer is C: 5.

Solve 19cos θ = 5 cos θ + 14 for all values of θ if θ is measured in radians.
Bas_tet [7]

Answer:

Ф=xπ, x={0,+∞}

Step-by-step explanation:

be 19cosФ=5cosФ+14 → 19cosФ-5cosФ-14 → 14cosФ-14=0 → cosФ=1

then,  values for which cosФ=1 are Ф=0º=360º=720º........., but the values of Ф  must be radians, so Ф=xπ, where x∈Z, not including the negative numbers,

x={0,1,2,3,....∞}

Note: π≅3.141592

when calculating the values, it must be done in radian mode
