Z= a/m, for a <br> It a literal equation

nydimaria [60]

Answer:

a = zm

Step-by-step explanation:

z = a/m for a

Multiply all sides by m

zm = a or a = zm

Example:

2 = 6/3

in this case, z = 2, a = 6, and m = 3

We would multiply z(2) and m(3) to get a(6)

The pie chart to the right shows how adults rate their financial shape. Suppose 4 people are chosen at random from a group of 11

vekshin1

Answer:

Step-by-step explanation:

Given that a pie chart shows data as

Excellent 7%

Good 44%

Fair 35%

Poor 13%

Other 1%

If 4 people are chosen at random we find that each person is independent of other and there are two outcomes either excellent or not excellent.

p = Prob for success = p = 7%=0.07

q = Prob for non success = 1-0.07 = 0.93

If x is a random variable representing the excellent persons then X is binomial with n =4, p = 0.07

Required probability = P(X=4)

= $p^4\\=(0.07)^4\\=0.00002401$
