Identify which statement about the mean of a discrete random variable is not true or state that they are all true.Choose the cor
pashok25 [27]

Answer:

A, C are true .  B is not true.

Step-by-step explanation:

Mean of a discrete random variable can be interpreted as the average outcome if the experiment is repeated many times. Expected value or average of the distribution is analogous to mean of the distribution.

The mean can be found using summation from nothing to nothing x times Upper P (x) , i.e ∑x•P(x).

Example : If two outcomes 100 & 50 occur with probabilities 0.5 each. Expected value (Average) (Mean) : ∑x•P(x) = (0.5)(100) + (0.5)(50) = 50 + 25 = 75

The mean may not be a possible value of the random variable.

Example : Mean of possible no.s on a die = ( 1 + 2 + 3 + 4 + 5 + 6 ) / 6 = 21/6 = 3.5, which is not a possible value of the random variable 'no. on a die'

PLEASE ANSWER I GIVE BRAINLIEST write an equation of a line with m=6 that passes through (7,-5)
iren [92.7K]

Answer:

y = 6x - 47

or

6x - y - 47 = 0

Step-by-step explanation:

y -  y_{1} = m(x -  x_{1} ) \\  \\ plug \: x_{1} = 7 \\  y_{1} =  - 5 \\ m = 6 \: in \: the \: above \: equation \\ y - ( - 5) = 6(x - 7) \\  \\ y + 5 = 6x - 42 \\  \\ y = 6x - 42 - 5 \\  \\ y = 6x - 47 \\  \\ or \: 6x - y - 47 = 0

The table and graph show that there are 32 ounces in a quart.
antiseptic1488 [7]

Answer:

The point (56, 1.75) is on the line.

Step-by-step explanation:

Given two points, we can get the slope (m) as follows:

m = (y2 - y1)/(x2 - x1)

where (x1, y1) and (x2, y2) are the points. Replacing with (8, 0.25) and (16, 0.5):

m = (0.5 - 0.25)/(16 - 8) = 0.03125

The point-slope form of a line is:

y - y1 = m(x - x1)

Replacing with data:

y - 0.25 = 0.03125(x - 8)

To know if point (56, 1.75) is on the line, we have to replace x = 56 in the obtained equation and check y-value, as follows:

y - 0.25 = 0.03125(56 - 8)

y - 0.25 = 1.5

y = 1.5 + 0.25 = 1.75

Then, the point is on the line. This means that there are 56 ounces in 1.75 quarts.
