Answer: 0.12
Step-by-step explanation:
The expected number of accidents is a weighted average of the potential number of accidents and their probabilities:
= (0 * 0.935) + (1 * 0.03) + (2 * 0.02) + (3 * 0.01) + (4 * 0.005)
= 0.12
Last month, a truck driver made
5 round-trips to Los Angeles and some round-trips to San Diego.
Write an expression that shows how many miles he drove in all.
Identify and describe the part of the expression that shows how
many miles he drove and trips he made to San Diego.
Example Answer:
You could represent a round trip to Los Angeles with the variable: x
You could represent the number of miles in a round trip to Los Angeles with the variable: a
You could represent a round trip to San Diego with the variable: y
You could represent the number of miles in a round trip to San Diego with the variable: b
your equation would be: xa + yb
Factoring in what we know, the example equation would be:
5a + yb
The sales tax in a certain county is 7%. If an item marked at $19.94 is sold within the county, estimate the final cost of the item once tax is included.
Given:
Rate of sales tax = 7%
Marked price of an item = $19.94
To find:
The final cost of the item once tax is included.
Solution:
We have,
Rate of sales tax = 7%
Marked price of an item = $19.94
[tex]\text{Sales tax}=\dfrac{7}{100}\times 19.94[/tex]
[tex]\text{Sales tax}=1.3958[/tex]
Now, final cost of the item once tax is included is
[tex]\text{Final cost}=\text{Marked price}+\text{Sales tax}[/tex]
[tex]\text{Final cost}=19.94+1.3958[/tex]
[tex]\text{Final cost}=21.3358[/tex]
Therefore, the final cost of the item once tax is included is $21.3358.
Triangle A B C is cut by line segment M N. Line segment M N goes from side A B to side B C and cuts both sides into equal parts. The lengths of A M and M B are 88 centimeters, the lengths of C N and N B are 75 centimeters, and the length of A C is 116 centimeters. What is the length of Line segment M N? 58 cm 75 cm 88 cm 116 cm
Answer:
A
Step-by-step explanation:
Edge
The measure of MN is equal to 58cm, the correct option is A.
What is a Triangle?A triangle is a polygon with three sides, vertices and angle.
Triangle A B C is cut by line segment M N.
such that,
A M = M B = 88 centimeter
CN =NB = 75 centimeter
AC = 116 centimeter
If a line segment joins the mid-points of two sides of a triangle, then the line segment is parallel to the third side of the triangle and the measure is equal to half of its length.
MN = (1/2) AC
MN = (1/2) * 116
MN = 58 centimeter

Answer : Answer:
a) $10 per hour
b) Sandra
Step-by-step explanation: he equation y 10x describes the amount of money Sandra earns, where x is the number of hours she works and y is the amount of money she earns
The table shows the amount of money Susan cams for different numbers of hours worked
Susan's Earnings
Time (h) Money Earned
5 40
8 64
10 80
(a) How much money does Sandra eam per hour? Show your work
(b) Who earns more per hour? Justify your answer
Answer:
a)
y = 10x is sandra's equation. To find her hourly rate, we need to find how much she earns in "1" hour. Since x is hours, we plug in x = 1 and find y (which is her pay).
y = 10x
y = 10(1)
y = 10
$10 is Sandra's hourly rate.
b)
To find who earns more per hour, we need to find the hourly rate of Susan as well from the table. Then compare.
5 hours = $40 so per hour is 40/5 = 8
8 hours is 64, so per hour 64/8 = 8
10 hours is 80, so 80/10 = 8
The table is justified at $8 per hour.
We know Sandra earns $10/hr and Susan earns $8 per hour. So Sandra earns more per hour.
An insurance company charges Ted E. Bear $1400 per year for insurance on his home. The company has predicted that there is a 10% chance that Ted will make a claim on the policy of $5000. Create a probability distribution and determine what the insurance company can expect to make on this policy, on average?
Answer:
$900
Step-by-step explanation:
The given parameters are;
The amount Ted pays per year for insurance on his home = $1,400
The value of the insurance policy = $5000
The chance that Ted will make a claim on the policy = 10%
The expected value is given as follows
Incidence Probability(p) Value(v) v × p
A claim is made 0.1 $5,000 - $1,400 = -$3,600 -$360
No claim 0.9 $1,400 $1260
Expected value is $1,260 - $360 = $900
The value the insurance company can be expected to make on average on the policy is $900
When packing a sultcase for a trip, the optimal welght of the suttcase Is 40 pounds. You aim for this weight with every trip you take. But your
sultcase's actual welght tends to vary by at most a certain number of pounds.
Part A. Write an absolute value inequality that models this relationship.
Part B. If the suitcase weight can vary by at most 7.5 pounds,what inequality can be used to find the range of acceptable weights for your suitcase?
Part C. Use the inequality from part B to determine the range of acceptable weights for the suitcase.
Part E. How would the inequality in part B change if you wanted to know the rate of weights that are unacceptable for your suitcase? Explain.
Part F. What is the solution for the inequality you created in part E?
Part H. What comparisons can you make between the two inequalities?
Part I. Will there ever be an instance where there is no solution to an absolute inequality? If yes,then what would the inequality look like?
Answer:
|x − 40| ≤ 7.5.
Step-by-step explanation:
The absolute value inequality |x − 40| ≤ y models the relationship between the acceptable weights of the suitcase and the amount it can vary.
If the suitcase weight can vary up to 7.5 pounds, then 7.5 can be substituted for y in the inequality:
|x − 40| ≤ 7.5.
This inequality can be used to find the range of acceptable weights of the suitcase.
Add. Write your answer in the simplest form.

Kevin works at a restaurant. He stacks glasses as shown below. Let x be the number of glasses and f(x) be the height of the stack. If 5.5-inch glasses with 1.2-inch lips are stacked vertically, which table correctly models this situation?
Answer:
[tex]f(x) = 5.5x + 1.2 \\ \: is \: the \: required \: situation.[/tex]
As per the given condition f(x) = 5.5x +1.2 inch will be the required model.
What is function?" A function is a mathematical expression to represent the relation between one or more variable."
According to the question,
x represents the number of glasses
f(x) represents the height of the stack
height of the glass = 5.5inch
stack vertically with height = 1.2 inch
Therefore,
Required model
f(x) = 5.5x +1.2
Hence, f(x) = 5.5x +1.2 inch will be the required model.

Which best describes the statement a plane contains at least 3 points not on the same line?
a. always true
b. sometimes true
c. never true
d. cannot tell
Answer: a. always true
Step-by-step explanation:
A plane is defined as a line and a point outside this line.
We know that for any set of two points, we can draw a line throug them.
Then if we have "3 points not in the same line" is equivalent to have two points in the same line, and the third point outside of it, then this is the definition of a plane.
Then the correct option is A, always true.

10. Use the perimeter formula. Collect terms, subtract* the constant, divide by the coefficient of the variable.
P = 2(L+W)
42 = 2(5x +(x-3))
21 = 6x -3 . . . . . . divide by 2, collect terms
24 = 6x . . . . . . . . add 3
4 = x . . . . . . . . . . divide by 6

11. Collect terms, subtract the constant, divide by the coefficient of the variable.
-8x -3(2x +1) = 67
-8x -6x -3 = 67 . . eliminate parentheses
-14x -3 = 67 . . . . . collect terms
-14x = 70 . . . . . . . add 3
x = -5 . . . . . . . . . . divide by -14

* "Subtract" and "add the opposite" are the same mathematical operation. In both these problems, the constant we want to get rid of is -3, so we add 3 (the opposite of -3). Of course, that operation is done to both sides of the equation.
