Answer:
<em>EX=2.68 ≈ 3</em>
<em>Lakeside Olds should expect 3 automobiles lined up at opening</em>
Step-by-step explanation:
<u>Expected Value of a Discrete Probability Distribution</u>
Given a discrete probability distribution of values
x={x1,x2,x3...,xn}
And probabilities
p={p1,p2,p3,...,pn}
Provided the sum of all probabilities is 1, then the expected value of the distribution is
EX =
The data refers to the number of automobiles lined up at Lakeside Olds at opening time for service:
x={1,2,3,4}
And probabilities
p={ 0.40 , 0.03 , 0.06 , 0.51 }
Checking the sum: 0.40 + 0.03 + 0.06 + 0.51 = 1
Now compute the expected value
EX= 1*0.40+2*0.03+3*0.06+4*0.51
EX=2.68 ≈ 3
Lakeside Olds should expect 3 automobiles lined up at opening
8 would be the constant but in this situation there is a variable next to it so I’m not sure if it would be considered a constant
Answer:
Step-by-step explanation:
Based on the figure given:Angle S is equal to 34 degrees.The triangle is inscribed in a circle, we can assume that the triangle is a right triangle. Thus, the measure of angle U is180 - 90 - 34 = 56 degrees. This is equivalent to the measure of the arc opposite the angle. Therefore, the measure of arc ST is also 56 degrees.
56 / (7/8) =
56 * 8/7 =
448/7 =
64.......so there are 64 total paperclips
64 * 0.03 = $ 1.92 <=== to get a total of 56 inches, u would have to use 64 paper clips costing u $ 1.92
The florists charges and delivery are illustrations of linear functions
The amount made by the florist per delivery is y = 1.5 + 0.25x
<h3>How to determine the functions</h3>
For the charges, we have:
- Delivery = $5.00
- Rate = $1.00 per mile
Represent the cost with y, and the number of miles with x.
The function that represents the amount the florist made is:
y = 5 + x
For the delivery, we have:
- Gas = $3.50
- Rate = $0.75 per mile
The function that represents the delivery is:
y = 3.5 + 0.75x
The amount made by the florist per delivery is then calculated as:
y = 5 - 3.5 + x - 0.75x
y = 1.5 + 0.25x
