An experiment results in one of the sample points Upper E 1, Upper E 2, Upper E 3, Upper E 4, or Upper E 5. Complete parts a through c. a. Find P(Upper E 3) if P(Upper E 1)equals0.2, P(Upper E 2)equals0.2, P(Upper E 4)equals0.1, and P(Upper E 5)equals0.2.

answer:  

step-by-step explanation:

here x represents the height of the pole,

and, the height of the shadow of the pole is 12 feet.

also, the angle of elevation from the top of the pole is 40°,

therefore,

by the low of sine,

which is the required equation for finding the value of x,

answer: b)

step-by-step explanation:

its a dot plot because since the score is not high numbers.

answer:

it is general formula that is used to write value to its excet position

a11 a12 a13

a21 a22 a23

it is the example of order 2 by 3 matrix in this

a11 means value occur in 1 st row 1st column

a12 means value occurs in 1st row 2nd column

a13 means value occur in 1st row and 3rd column

a21 means value occurs in 2nd row and 1st column

a22 means value occurs in 2nd row and in 2nd column

a23 means value occurs in 2nd row and in 3rd column
