Answer:
Ana spent $17 per book on average.
Juan spent $14.78 per book on average.
y = $15 + 17x--------- equation 1
y= $10 + 14.78 x------------- equation 2
Step-by-step explanation:
Ana has to pay a yearly fee of $15 to join.
She spends a total of $525 for 30 books.
The amount spent on books = Total amount - yearly fee
= $525- $15= $510
Price per book on the average = $510/30= $ 17
Ana spent $17 per book on average.
Juan has to pay a yearly fee of $10 to join.
He spends a total of $350 for 23 books.
The amount spent on books = Total amount - yearly fee
= $350- $10= $340
Price per book on the average = $340/23= $ 14.78≅ $15
Juan spent $14.78 per book on average.
The function can be established if y gives the total cost and x gives the number of books
y = $15 + 17x--------- equation 1
y= $10 + 14.78 x------------- equation 2
Juan has a better deal because the yearly fee is less also the price per book is less.

Which value cannot represent the probability of an event occurring?
options are:
0.01
2 over 85
62.5%
1.1
Answer:
1.1
Step-by-step explanation:
1 in probability means always so anything greater than 1 is meaningless
A construction company has two divisions: ceilings and floors. The amount of revenue for the ceiling division, C, is approximately Normally distributed with a mean of $2.6 million per year and a standard deviation of $0.9 million per year. The amount of revenue for the flooring division, F, is approximately Normally distributed with a mean of $3.1 million per year and a standard deviation of $1.1 million per year. Assume C and F are independent random variables.
What is the probability that the ceiling division makes more revenue than the flooring division in a randomly selected year?
0.006
0.363
0.401
0.637
Answer:
The correct anwer is 0.363

Megan creates a scale drawing of a car. The ratio of her scale drawing length to actual car
length is 3 cm : 2 m. The length of the car in her drawing is 6 cm.
Ivan draws a scale drawing of the same car. His ratio of scale drawing length to actual car
length is 2 cm : 1m.
What is the length of the car in Ivan's scale drawing?
Answer : 12cm
Step-by-step explanation:
Answer:
im thinking its 12

Find the value of x.
Answer:
11
Step-by-step explanation:
All angles on a triangle equal 180. 80+60=140.
Now to solve for x, we set it to equal 40 for 180-140.
40=3x+7. 40-7=33
33=3x 33/3=11
x=11

you have a bucket that contains 3 red baseballs , 4 white baseballs, and 5 green baseballs. you are going to pick out one baseball, leave it out, and then pick another baseball. what is the probability of picking out a white baseball followed by a green baseball?
Answer:
probably a 60%
Step-by-step explanation:
Answer:
5/44
Step-by-step explanation:
3 plus 4 plus 5 is 12 so for a white it is 4/12 or 1/3
then you take out the white baseball and you want a green which is 5/11 3 red 3 white 5 green
5/11 times 1/3 is 5/33
so the odds of picking both is 5/33

Answer:
Y = 28.31
Z = 13.29
Angle A = 28
Step-by-step explanation:
For Angle A:
Remember a triangle has a total of 180 degree angles. So set up your formula as
180 - 62 -90 = Angle A
For Y:
The sine of an angle is equal to the ratio of the opposite side to the hypotenuse.
sin (B) = opp/hyp or b/c or (y)
sinB = 62
b = 25
Rewrite as c=b/2SinB -> c=25/sin62 -> Y = 28.31
For Z:
Use the Pythagorean theorem to find the unknown side.
[tex]z^{2} = 28.31^{2} - 25^{2}[/tex]
z = 13.29

Mark's father was putting in a new kitchen floor. The dimensions were 8 feet by 12 feet. If each tile was 1 square foot, how many tiles did he need?
Answer:
96 tiles
Step-by-step explanation:
The kitchen floor is rectangular on shape.
The dimensions of the kitchen floor were 8 feet by 12 feet.
Hence, Area of a rectangle = Length × Width
Length = 8ft
Width = 12ft
Hence:
Area = 8ft × 12ft
= 96 ft²
If each tile was 1 square foot, the number of tiles he would need is
1 ft² = 1 tile
96 ft² = x
Cross Multiply
1ft² × x = 96 ft² × 1 tile
x = 96 ft² × 1 tile/1 ft²
x = 96 tiles
Therefore, Mark's father would need 96 tiles

The attendance office creates a bar graph to display the number of students tardy throughout the month. What is the range of the number of students tardy during the first five months of the year?
Answer:
60
Step-by-step explanation:
To find the range you subtract the highest and lowest value
The highest value on this graph is 105 from the month of May and the lowest value is 45 from the month of March.
When you do 105-45 you get 60 which is the range

Step-by-step explanation:
Perimeter= all sides added together
so in this case
3x+1 = 2x + 2x + x-1 + x+2 + x-1 + x + 2
now you may be wondering why i put two 2x's, two 2+x, and two x-1 , the far left side is 2x and has 2 lines and so does the bottom side which has 2 lines so theyre congruent ( the same case for the 2+x and x-1 ) so you need to account for all sides.
so lets simplify this huge equation!
3x+1 = 4x + 1x - 1 + 1x + 2 + 1x - 1 + 1x + 2
3x+1 = 8x - 1 + 2 - 1 + 2
3x + 1 = 8x + 2
-3x on both sides
1 = 5x + 2
-2 on each side
-1 = 5x
x = -1/5
