In a particular city, the population proportion π supports an increase in the minimum wage. for a random sample of size 2, let y = number who support an increase. a. assuming π = 0.50, specify the probabilities for the possible values y for y and find the distribution’s mean and standard deviation. b. suppose you observe y = 1 and do not know π . find and sketch the likelihood function. using the plotted likelihood function, explain why the ml estimate ˆ= π

reduce the friction between its moving parts

step-by-step explanation:

in fact, by reducing the friction between the moving parts of the machine, it is possible to reduce the energy wasted due to this friction; therefore, more input energy is converted into useful work, and this will improve the efficiency of the machine.

divide the numbers

step-by-step explanation:

●yes, this statement is absolutely apt.

hope this you

the speed is   miles per hour > is false

step-by-step explanation:

we know that  

a relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form or

in a proportional relationship the constant of proportionality k is equal to the slope m of the line and the line passes through the origin

the graph shown in the figure represent a direct variation

the slope of the line represent the speed

for the point

substitute the values of x and y

the linear equation is equal to

statements

case a) it takes hours to go miles

the statement is true

because

substitute

for

find the value of y in the linear equation

> is correct

case b) the speed is   miles per hour

the statement is false

because the speed is

case c) the unit rate for the trip is

the statement is true

because the speed is equal to the slope of the linear equation

case d) it took minutes to go the first miles

the statement is true

because

substitute

for

find the value of y in the linear equation

> is correct
