The perimeter of a square is 4 times the length of one side of the square. Which graph represents this situation? *
Arisa [49]

Answer:

A.

Step-by-step explanation:

Graph B must be incorrect as this is a directly proportional relationship. Likewise, graph C shows an inversely proportional relationship.

Between graph A and D, only graph A passes through the origin, which is true because if length is zero, perimeter is zero.

Hence the answer is Graph A.

The probability distribution function for the discrete random variable where x is equal to the number of red lights drivers typi
Ivahew [28]

Using probability concepts, it is found that:

a) The missing value is 0.04.

b) The mean is of 0.37.

The distribution is given by:

P(X = 0) = 0.76

P(X = 1) = 0.15

P(X = 2) = 0.05

P(X = 3) = x

Item a:

The sum of <u>all the probabilities has to be 1</u>, that is:

\sum_{i = 0}^{3} P(X = i) = 1

Thus:

0.76 + 0.15 + 0.05 + x = 1

0.96 + x = 1

x = 0.04

The missing value is 0.04.

Item b:

The mean is given by the <u>sum of each outcome multiplied by it's probability</u>, thus:

E(X) = 0(0.76) + 1(0.15) + 2(0.05) + 3(0.04) = 0.37

The mean is of 0.37.
