Jill earn $15 per hour babysitting class a transportation fee of five dollars per job. Write a formula for E, Ji Jill earn $15 p

daser333 [38]

Since you know the amount of what she earns you would use the number 15 and you dont know how long she worked you would put "x" next to the 15. so you would have 15x and then put a plus 5 to show her transportation fee. so you would have the equation of 15x+5:) and instead of x use h to show hours because h=hours

you feel me?
great!

The entertainment committee voted to hire a DJ for the school dance. The DJ

nydimaria [60]

A 4 hours

This is because if you create the equation using $75 which is the starting fee and then $30 for every hour of playing music.

Equation: 75+30h<200
You subtract 75 from 200 and the divide that number by 200 you will get a decimal but you look at your answer choices and choose the closest number to your answer.

What is the significance of the mean of a probability distribution?

VikaD [51]

Answer:

Significance of the mean of a probability distribution.

Step-by-step explanation:

The mean of a probability distribution is the arithmetic average value of a random variable having that distribution.

For a discrete probability distribution, the mean is given by, $\sum x_iP(x_i)$ , where P(x) is the probabiliy mass function.
For a continuous probability distribution, the mean s given by, $E(x) = \int x_if(x_i)$ , where f(x) is the probability density function.
Mean is a measure of central location of a random variable.
It is the weighted average of the values that X can take, with weights given by the probability density function.
The mean is known as expected value or expectation of X.
An important consequence of this is that the mean of any symmetric random variable (continuous or discrete) is always on the axis of symmetry of the distribution.
For a continuous random variable, the mean is always on the axis of symmetry of the probability density function.
