Chance of winning $100 = 1/1000 
<span>chance of winning $50 = 5/1000 = 1/200 </span>
<span>cost of ticket = -1 </span>
<span>E[x] = 100* 1/1000 + 50* 1/200 -1 </span>
<span>= 0.1 + 0.25 - 1 = -0.65 

Hope this helps</span>

A recent poll of 124 randomly selected residents of a town with a population of 310 showed that 93 of them are opposed to a new
tester [92]
The sample size is 124.
93 of them are opposed to new shopping center.

So, 
n = 124
p = \frac{93}{124}=0.75

The point estimate of the population proportion = p = 0.75
q = 1 - p = 0.25

Margin of error (E) can be calculated by:

E= Z_{c}  \sqrt{ \frac{pq}{n} }

Using the values, we get:

E=1.645 \sqrt{ \frac{0.75*0.25}{124} }=0.06

Therefore, the margin of error is approximately 0.06 or 6%.

what is a correct first step in solving the inequality –4(3 – 5x)≥ –6x 9? –12 – 20x ≤ –6x 9 –12 – 20x ≥ –6x 9 –12 20x ≤ –6x 9 –1
DIA [1.3K]
<span>The answer is -12 + 20x ≥ –6x 9. The inequality is –4(3 – 5x)≥ –6x 9. The first step is to multiply factors on the left side. The intermediary steps are: (-4)*(3) - (-4)*(5x) ≥ –6x 9. -12 - (-20x) ≥ –6x 9. So, the first step will be: -12 + 20x ≥ –6x 9.</span>

Kate writes an algebraic expression using each of the variables x and y only once. they first expression she writes uses x and y
kotykmax [81]

Answer:

B: Using x and y factor results in an expression of greater value than using x and y as terms.

Step-by-step explanation:

For her first expression, x and y are factors;

xy

For her second expression, x and y are written as terms;

x + y

For x and y are both negative integers, then;

-x * -y = xy  ............... 1

-x + (-y) = - x - y

            = - (x + y)  .............. 2

Therefore, the value of x and y factors is greater than that when x and y are as terms. Thus the correct option is B.
