Find the expected number of accidents
each day.

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
Graham walked to school at an average speed of 3 miles an hour and jogged back along the same route at 5 miles an hour. If his total traveling time was 1 hour, what was the total number of miles in the round trip?
x/3 + x/5 = 1 hr
8x/15 = 1 hr
x = 15/8
15/8 times 2 for round trip. 15/4 miles or 3.75 miles total

Answer: C
Step-by-step explanation:
1.25 + (- 0.75) is equal to 1.25 - 0.75.
1.25 is positive while - 0.75 is negative. So 1.25 is head toward the right while - 0.75 is head toward the left.
And when you substract them, you will get 0.5.
So the answer is C.

Answer:
10. x = 4
11. x = -5
Step-by-step explanation:
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.

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.

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

Write the values of n such that -15<3n≤6
Answer:
n = - 4, - 3, - 2, - 1, 0, 1, 2
Step-by-step explanation:
Given
- 15 < 3n ≤ 6 ( divide the 3 intervals by 3 )
- 5 < n ≤ 2
Thus n ≠ - 5 but n can equal the upper limit of 2
Hence
n = - 4, - 3, - 2, - 1, 0 , 1, 2

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.

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.

explicit formula:
f(n) = 8 + 3(n - 1)
[tex]\boxed{\boxed{\pink{\bf \leadsto The \ 22nd \ term \ is \ 71. }}}[/tex]
Step-by-step explanation:Given that the nth term of the Arthemetic Sequence is given by :-
[tex]\implies f(n) = 8 + 3(n-1) [/tex]
And we need to find the 22nd term .
So in place of n substitute 22 .
[tex]\bf\implies f(n) = 8 + 3(n-1) \\\\\bf\implies f_{22} = 8 + 3(22-1) \\\\\bf\implies f_{22} = 8 + 3\times 21 \\\\\bf\implies f_{22} = 8 + 63 \\\\\bf\boxed{\bf\implies f_{22} = 71 }[/tex]

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
