Answer:

Probability that all winner are men = 0.0035 (Approx.)

Step-by-step explanation:

Given:

Number of women = 50

Number of men = 26

Total number winner = 5

Find:

Probability that all winner are men

Computation:

Total competitor = 50 + 26 = 76

Probability that all winner are men = 26/76 x 25/75 x 24/74 x 23/73 x 22/72

Probability that all winner are men = 7,893,600 / 2,216,980,800

Probability that all winner are men = 0.0035 (Approx.)

Which of the following is NOT a variation of a Pythagorean identity?​
Ipatiy [6.2K]

The expression that is not a variation of the Pythagorean identity is the third option.

<h3>What is the Pythagorean identity?</h3>

The Pythagorean identity can be written as:

sin^2(x) + cos^2(x) = 1

For example, if we subtract cos^2(x) on both sides we get the second option:

sin^2(x) = 1 - cos^2(x)

Which is a variation.

Now, let's divide both sides by cos^2(x).

sin^2(x)/cos^2(x) + cos^2(x)/cos^2(x) = 1/cos^2(x)\\\\tan^2(x) + 1 = sec^2(x)\\\\tan^2(x) - sec^2(x) = -1

Notice that the third expression in the options looks like this one, but the one on the right side is positive. The above expression is in did a variation of the Pythagorean identity, then the one written in the options (with the 1 instead of the -1) is incorrect, meaning that it is not a variation of the Pythagorean identity.

Concluding, the correct option is the third one.

F(x)=−2x+16<br> g(x)=4x+10<br> please give me the intersection points
vagabundo [1.1K]

Answer:

  • (1, 14)

Step-by-step explanation:

The intersection is when both functions have same coordinates

  • f(x) = g(x)

Substitute to get

  • - 2x + 16 = 4x + 10
  • 4x + 2x = 16 - 10
  • 6x = 6
  • x = 1

The y- coordinate is

  • y = - 2(1) + 16 = -2 + 16 = 14

So the intersection point is (1, 14)
