Answer:

Probability that a gym member does not take weight-loss medication = 0.63

Step-by-step explanation:

Let E be the event of choosing a gym member who drank protein shakes and W be the event of choosing a gym member who took weight loss medication.

Probability that a gym member drank protein shakes = P(E) = 0.9

Probability that a gym member does not drink protein shakes = P(not E) = 0.1

E and W are independent events.

By using Bayes Theorem, P(E and W) = P(E)*P(W)

Probability that a gym member drank protein shakes and took weight loss medication = P(E and W) = 0.3*0.9 = 0.27

Probability that a gym member took weight-loss medication = P(W) = 0.1 + 0.27 = 0.37

(10% of members who did not drink protein shakes took weight-loss medication)

Therefore, Probability that a gym member does not take weight loss medication = P(not W) = 1 - 0.37 = 0.63

Let f(x)=5/x and g(x) =2x^2+5x. What two numbers are not in the domain of F o G?
expeople1 [14]
F(x)=5/x
g(x)=2(x^2)+5x
f(x) has a domain of all real numbers excluding zero
g(x) has a domain of all real numbers
fog(x)=5/(2(x^2)+5x)
fog(x)=5/(x(2x+5))
fog(x) has a domain that excludes both zero and -5/2

Find the limit of the function algebraically lim (x^2 -36 / x+6 ) x ->6
posledela

9514 1404 393

Answer:

  0

Step-by-step explanation:

The function is defined everywhere except at x=-6. The limit value is the function value at that point.

  f(6) = (6^2 -36)/(6 +6) = 0/12 = 0

The limit of the function is 0 as x → 6.

A map is laid out in the standard (x,y) coordinate plane. How long, in units, is an airplane's path on the map as the airplane f
xeze [42]

Answer:

Distance between the points A and B is 15.52 units.

Step-by-step explanation:

It has been given in the question that an airplane flies along a straight line from City A to City B.

Map has been laid out in the (x, y) coordinate plane and the coordinates of these cities are A(20, 14) and B(5, 10).

Distance between two points A'(x, y) and B'(x', y') is represented by the formula,

d = \sqrt{(x-x')^{2}+(y-y')^{2}}

So we plug in the values of (x, y) and (x', y') in the formula,

d = \sqrt{(20-5)^{2}+(14-10)^{2}}

d = \sqrt{(15)^{2}+(4)^{2}}

d = \sqrt{225+16}

d = 15.52

Therefore, distance between the points A and B is 15.52 units.
