Anna is planning a big birthday bash for her sixteenth birthday party and wants to invite as many people as possible but she has
Doss [256]
Im not an expert or anything, but i think for the innequality, i would say

6.50p + 100 \leqslant 500

as far as the amount of people she can invite, do 500-100=400 because of the setup fee, then, to find how many people she can invite. 400÷6.50 which leaves you with the highest amount of people she can invite without going over budget, as 61.

A random variable is uniformly distributed over the interval [-4, 6]. find the mean, variance, and standard deviation of .
Lyrx [107]

The mean, variance, and standard deviation are 1, 8,33 and 2.89

<h3>How to find the mean, variance, and standard deviation?</h3>

The distribution is given as:

[a, b] = [-4, 6]

The mean is calculated as;

Mean = (a + b)/2

So, we have

Mean = (-4 + 6)/2

Evaluate

Mean = 1

The variance is calculated as;

Var = (b - a)^2/12

So, we have

Var = (6 + 4)^2/12

Evaluate

Var  = 8.33

The standard deviation is calculated as;

SD= sqrt(Var)

So, we have

SD = sqrt(8.33)

Evaluate

SD = 2.89

Hence, the mean, variance, and standard deviation are 1, 8,33 and 2.89
