In a classroom libray Mrs. Sterling has 16 mystery books, 4 fantasy, 4 biographies, 4 poetry books, 2 comic books, and 2 cookbooks. A book is selected from the classroom library at random. What is the probability that the book is a mystery book?
Such probability is calculated by dividing the number of mystery books by a total number of books:
--> [tex]\frac{16}{32} = \frac{1}{2}[/tex]
Thus the probability that the book is a mystery book is 1/2.

The table that shows a constant rate of change of -3 is Table D.
Option D is the correct answer.
What is an expression?An expression contains one or more terms with addition, subtraction, multiplication, and division.
We always combine the like terms in an expression when we simplify.
We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.
Example:
1 + 3x + 4y = 7 is an expression.com
3 + 4 is an expression.
2 x 4 + 6 x 7 – 9 is an expression.
33 + 77 – 88 is an expression.
We have,
The constant rate of change (r):
Take two ordered pairs (a, b) and (c, d)
= (d - b) / (c - a)
Now,
From Table D.
We see that,
r = (-1 - 2) / (-21 + 22) = -3/1 = -3
r = (-4 + 1) / (-20 + 21) = -3/1 = -3
r = (-7 + 4) / (-19 + 20) = -3/1 = -3
Thus,
The table that shows a constant rate of change of -3 is Table D.

Step-by-step explanation:
The sum of the measures of the angles of a triangle is 180. The sum of the measures of the second and third angles is five times the measure of the first angle. The third angle is 16 more than the second. Let x, y, and z represent the measures of the first, second, and third angles, respectively
Answer:
x = 30 degrees
y = 67 degrees
z = 83 degrees
Step-by-step explanation:
Let's first set up a few equations. We know:
x + y + z = 180
y + z = 5x
z = y + 16
Let's now solve our equations through substitution. We'll substitute variable z in equations one and two for (y + 16), which is possible thanks to our third equation.
Now, our second equation has become:
y + y + 16 = 5x
So...
5x = 2y + 16
Our first equation is now:
x + y + y + 16 = 180
So...
x + 2y = 180 - 16
And...
x + 2y = 164
Finally...
x = 164 - 2y
Let's take a look at our new first and second equations:
5x = 2y + 16
x = 164 - 2y
Let's substitute again, replacing x in the first equation with (164 - 2y).
Our first equation is now the following:
5(164 - 2y) = 2y + 16
We can apply the Distributive Property to get:
820 - 10y = 2y + 16
So...
-10y - 2y = 16 - 820
-12y = -804
y = 67
Now that we have found y, we can find x and z.
We know that the third angle z is 16 more than the second, y. That was our third equation, z = y + 16.
So, z = 67 + 16.
z = 83.
We know the sum of the y and z is five times the measure of x.
(83 + 67)/5 = 30
To check our work, we can do 67 + 83 + 30 = 180. So we know we are correct.
The Big Motor Works (BMW) is considering a production schedule for cars and trucks over the next two months. They must deliver on time 400 trucks and 800 cars in month one. In month two, their demand is 300 trucks and 300 cars. During each month, at most 1,000 vehicles can be built. Each truck uses two tons of steel and each car uses one ton of steel. During the first month, the steel cost will be $400 per ton. During the second month the cost of steel will go up to $600 per ton. At most 2,500 tons of steel can be purchased in each month. (Steel can only be used in the month it is purchased.) At the beginning of month one, 100 trucks and 200 cars are in inventory. At the beginning of each month a hold- ing cost of $150 per vehicle is assessed. Each car gets 30 mpg, and each truck gets 20 mpg. To meet fuel economy regulations, the vehicles produced each month must average at least 26 mpg. The company wants to minimize its total costs.
a. Formulate a linear program to help BMW determine how many cars and trucks it should produce each month and how many it should keep in inventory each month.
b. Use Solver to find the optimal solution to the linear program from part a. Using a sensitivity report from the Solver solution in part b, answer questions c—g.
c. How many trucks and how many cars should be produced in each month?
d. Suppose the price of steel fell by $25 per ton. What would be the total impact on optimal solution and optimal value?
e. The company just got notified the supply of steel has decreased from 2,500 tons to 2,000 tons. What impact will this have on their production plans?
f. The company is able to add overtime at a cost of $900 per car to increase total production in either month. Should they add overtime in either month? Why or why not?

Answer:
Php 973.00
Step-by-step explanation:
Aling Luz bought 3/8 yards of linen cloth which cost Php 72.00 per yard.She gave Php 1000.00 to the cashier.How much change will she?
Number of yards bought = 3/8
Cost of a yard = Phone 72.00
Cost of number of yards bought = Number of yards bought × Cost of a yard
= 3/8 × Php 72.00
= Php 27.00
She gave Php 1000.00 to the cashier.
How much change will she?
= Amount given to the cashier - cost of yards bought
= Php 1000.00 - Php 27.00
= Php 973.00

Pamela stopped at 1.8 miles marker. where will she be if she walks one tenth of a mile towards camp? one mile towards camp?Explain
I am pretty sure it is a because 2 is half of 4 and 18 is half of 36.
Step-by-step explanation:
Pamela will be 1.7 miles if she walks one-tenth of a mile toward camp.
What are Arithmetic operations?Arithmetic operations can also be specified by adding, subtracting, dividing, and multiplying built-in functions.
- Subtraction operation: Subtracts the right-hand operand from the left-hand operand.
for example 4 -2 = 2
At the 1.8-mile marker, Pamela stopped.
We have to determine the mile toward camp if she makes it a mile and a tenth of the way to camp.
Since a tenth of a mile is equal to one mile, if she is heading in the direction of the camp and the 1.8-mile marker is moving forward.
As per the given condition,
So remaining distance would be
⇒ 1.8 - (1/10)
⇒ 1.8 - 0.10
⇒ 1.7
Therefore, she will be 1.7 miles if she walks one-tenth of a mile toward camp.

Answer:
a) s = 2a sinh(b/a)
b) 18 feet
Step-by-step explanation:
The arc length is:
s = ∫ √(1 + (dy/dx)²) dx
y = a cosh(x/a)
y = ½ a (e^(x/a) + e^(-x/a))
dy/dx = ½ a (1/a e^(x/a) − 1/a e^(-x/a))
dy/dx = ½ (e^(x/a) − e^(-x/a))
(dy/dx)² = ¼ (e^(2x/a) − 2 + e^(-2x/a))
Plugging in:
s = ∫ √(1 + ¼ (e^(2x/a) − 2 + e^(-2x/a))) dx
s = ∫ ½ √(4 + e^(2x/a) − 2 + e^(-2x/a)) dx
s = ∫ ½ √(e^(2x/a) + 2 + e^(-2x/a)) dx
s = ∫ ½ √(e^(x/a) + e^(-x/a))² dx
s = ∫ ½ (e^(x/a) + e^(-x/a)) dx
s = ½ (a e^(x/a) − a e^(-x/a))
s = ½ a (e^(x/a) − e^(-x/a))
Evaluate from x=-b to x=b:
s = ½ a (e^(b/a) − e^(-b/a)) − ½ a (e^(-b/a) − e^(b/a))
s = ½ a e^(b/a) − ½ a e^(-b/a) − ½ a e^(-b/a) + ½ a e^(b/a)
s = a e^(b/a) − a e^(-b/a)
s = a (e^(b/a) − e^(-b/a))
s = 2a sinh(b/a)
We know that s = 48, and b = 20. We also know y = 30 when x = b.
48 = 2a sinh(20/a)
24 = a sinh(20/a)
30 = a cosh(20/a)
Using the given identity:
cosh²(20/a) − sin²(20/a) = 1
a² cosh²(20/a) − a² sin²(20/a) = a²
30² − 24² = a²
a² = 324
a = 18

The table shows the amount of money Kaylee earns for different numbers of hours worked.
Kaylee’s Earnings
Time (h) 2 5 8 10
Money earned ($) 39 97.50 156 195
(a) How much money does Kaylee earn per hour? Show your work.
(b) Who earns more per hour? Justify your answer.
HELP ME PLEASEEEEE
Answer:
(a) Kaylee earns $19.50 per hour.
(b) Kaylee earns more money per hour than Joey.
Step-by-step explanation:
x = # of hrs. worked
y = amount of money earned
Joey:
y = 16.50x
Kaylee:
Time (h) 2, 5, 8, 10
Money earned ($) 39, 97.50, 156, 195
y = mx + b; Slope (m) = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]
We will be using: (2,39) and (8,156) to find the slope of this table.
[tex]m=\frac{y_2-y_1}{x_2-x_1} \\\\m=\frac{156-39}{8-2} \\\\m=\frac{117}{6} \\\\m=19.5[/tex]
y = mx + b
y = 19.5x + b
I will be using (2, 39) to find the value of b
(2, 39)
y = 19.5x + b
39 = 19.5(2) + b
39 = 39 + b
-39 -39
0 = b
y = 19.5x + b ==> y = 17.7x + 0 = OR y = 19.5x (since the value of b is 0)
(a) The question wants us to find out how money Kaylee earns per hour. Recall that x = # of hrs. worked and y = amount of money earned.
y = 19.5x
She earns $19.50 per hour.
(b)
Joey: y = 16.50x (earns $16.50 per hour)
Kaylee: y = 19.5x (earns $19.50 per hour)
As you can see, Kaylee earns more money per hour than Joey.
Hope this helps!
