Let x represent the number of laps Tony ran,

15 + 1.5x = 255
1.5x = 240
x = 160

Tony ran 160 laps.

<h2>Answer:</h2>

<h3>1) $\frac{1}{2}$ </h3><h3>3) $\frac{1}{6}$ </h3><h3>5) $\frac{2}{3}$ </h3><h3 /><h2>Step-by-Step Explanation:</h2><h3 />

1.<em> </em>Find the probability of rolling less than a four.

<u>Probability Outcomes</u> = 1, 2, 3, 4, 5, 6

<u>Outcomes lower than four</u> = 1, 2, 3

Then to answer it you need the probability in the form of a fraction.

$\frac{3}{6}$ simplifies into $\frac{1}{2}$

2. Find the probability of rolling an even prime number.

<u>Probability Outcomes</u> = 1, 2, 3, 4, 5, 6

<u>Prime Numbers Through 1-6</u> = 2, 3, 5

<u>Even Prime numbers Through 1-6</u> = 2

So the probability in the form of a fraction.

3. Find the probability of rolling factors of 20.

<u>Probability Outcomes</u> = 1, 2, 3, 4, 5, 6

<u>Factors of 20 Through 1-6</u> = 1, 2, 4, 5

So probabilty in the form of a fraction.

$\frac{4}{6}$ simplifies into $\frac{2}{3}$

Let θ be an angle in quadrant IV such that sinθ = -2/5 .<br> Find the exact values of secθ and tanθ.

Gnesinka [82]

If <em>θ</em> lies in the fourth quadrant, then sin(<em>θ</em>) < 0 and cos(<em>θ</em>) > 0. So we have from the Pythagorean identity,

sin²(<em>θ</em>) + cos²(<em>θ</em>) = 1 ==> cos(<em>θ</em>) = +√(1 - sin²(<em>θ</em>)) = √21/5

Then

sec(<em>θ</em>) = 1/cos(<em>θ</em>) = 5/√21

and

tan(<em>θ</em>) = sin(<em>θ</em>)/cos(<em>θ</em>) = (-2/5)/(√21/5) = -2/√21
