There are 70 students in a nutrition class. What is the probability that a junior non nutrition major and then a sophomore nutrition major are chosen at random?

0.62% or 1/161

Step-by-step explanation:

So first you must find the probability that the junior non nutrition major is chosen, this is 10/70. After this the total number of people is lowered down to 69 since one person was chosen. Then you find the probability of a sophomore nutrition major. This is 3/69. Then multiply the two probabilities together. 10/70*3/69 = 1/161 once you reduce it. And if you change it to percentage form it is 0.62%

sec ф = 5/3 (quadrant 4)

let x = base

y = perp

z = hypotenuse

sec ф = hypotenuse/base = 5/3

⇒ z = 5 and x = 3

finding y:

z² = x² + y²

5² = 3² + y²

y² = 25-9

y² = 16

y = 4

now finding all other geometric functions of theta:

sin ф = y/z = 4/5

sin ф = -4/5 (sin is negative in the 4th quadrant)

cos ф = x/z = 3/5

cos ф = 3/5 (cos is positive in 4th quadrant)

tan ф = y/x = 4/3

tan ф = -4/3 (tan is negative in 4th quadrant)

cosec ф = z/y = 5/4

cosec ф = -5/4 (cosec is negative in the 4th quadrant)

cot ф = x/y = 3/4

tan ф = -3/4 (tan is negative in 4th quadrant)
