Answer:
A bag contains 9 pennies, 8 nickels and 5 dimes: 22 coins total
5/30 = 1/6
22 + 8 = 30
8 quarters would give the needed 30 coin total
P(dime) = 5/30 = 1/6
Step-by-step explanation:
No quarters should be added to the bag so the probability of drawing a dime is 1/6
Let x be the number of quarters to be added to the bag.
The probability of drawing a dime can be found by dividing the number of dimes in the bag by the total number of coins in the bag after adding x quarters.
The total number of coins in the bag before adding any quarters is:
9 pennies + 8 nickels + 5 dimes = 22 coins
After adding x quarters, the total number of coins in the bag becomes:
9 pennies + 8 nickels + 5 dimes + x quarters = 22 + x coins
The probability of drawing a dime is given as 1/6.
So, we can set up the equation:
5 / (22 + x) = 1/6
30 = 5(22 + x)
30 = 110 + 5x
-80 = 5x
x = -16
Since x represents the number of quarters to be added, it cannot be negative. Therefore, it is not possible to add any quarters to the bag so that the probability of drawing a dime is 1/6.
Hence, the answer is zero quarters.

(Find The Probability Question)
Choose 2 apples to eat from a bowl containing 6 apples, 8 oranges, and 4 bananas.
Answer:
240/990 = 8/33.
Step-by-step explanation:
Arbitrarily, the chances of this outcome, by picking an apple first, then an orange, then a banana, is:
5/11 × 4/10 × 2/9= 40/990
But we don't care about the order and in reality, there are six orders that would achieve our outcome:
Apple, orange, banana
Apple, banana, orange
Orange, Apple, banana
Orange, banana, Apple
Banana, Apple, orange
Banana, orange, Apple
The probability of each these outcomes is the same as computed above (Just exchanging numerators.) So the answer is 6×(40/990)

Peter made a square pin for his pet guinea pig to roam in. One side was 18.2 cm. What is the area of the pin?
A. 331.24 cm
B. 321.24 cm
C. 74.8 cm
D. 72.8 cm
Hi!
Answer:
A) 331.24
Step-by-step explanation:
To find the area, you need to multiply LxW, (Length x Width) and in this case, since it's a square, the sides are equal. Each side is 18.2 cm, so all we have to do is multiply 18.2 by 18.2, and then we get 331.24, so your answer is option A.

What is the value of x given the following image?
Answer:
27
Step-by-step explanation:
CDE is a right angle so the sum of CDF and FDE is equal to 90
2x + x + 9 = 90 add like terms
3x + 9 = 90 subtract 9 from both sides
3x = 81 divide both sides by 3
x = 27

If you would think about it, p (earnings) relies on h (how long he worked), therefore it would be p=8h
Construct a scatter plot of these data using the following coordinate grid. The vertical axis represents the calories and the horizontal axis represents the fat (grams).
Answer: here is a lesson that helped me Discussion Points and Possible Answers
1. The table below shows the total fat in grams and total calories for various fast food items. Does this
data suggest that there is an association between the fat grams and total calories in fast food
items? Support your answer.
Sandwich Total fat (g) Total Calories
Hamburger 9 260
Cheeseburger 13 320
Quarter Pounder 21 420
Quarter Pounder with Cheese 30 530
Big Mac 31 560
Arch Sandwich Special 31 550
Arch Special with Bacon 34 590
Crispy Chicken 25 500
Fish Fillet 28 560
Grilled Chicken 20 440
Grilled Chicken Light 5 300
Sample Answers: The food items with more fat tend to have more calories, so it seems
reasonable that there is a positive association. Larger values of total fat tend to go with larger
values of total calories.
2. A scatter plot can be used to visualize the association between fat and calories. Think about how
the variables are related, and how the variables fat and calories should be placed on the
coordinate axes. Label the axes on the graph below, and explain your choice of axes and
variables.
Answer: Since the amount of fat in fast food affects the
total calories, the variable fat is the independent
variable. This variable is best to plot along the horizontal
axis. The variable calories is the dependent variable
and is, therefore, best to plot along the vertical axis.
Teacher Tip: Discuss with the students why fat is the independent variable
and calories is the dependent variable in this situation. Ask them whether
the amount of fat depends on how many calories are in the food, or the
amount of calories depend on how much fat is in the food.

Which expression is equivalent to 30x - 12y
10(3x + 2y)
6(5x + 2y)
6(5x - 2y)
10(3x - 2y)
Answer:
B) 6(5x -2y)
Step-by-step explanation:
When we have a number outside the parenthesis, we can distribute this number to all the terms inside the parenthesis. Since our given expression is 30x -12y, we are looking for an expression that when expanded results in these two numbers.
Only option B provides both 30x and -12y, as seen as 6 times 5x= 30x and 6 times -2y = -12y.

Reflection over the x -axis is (x,y) → (x,−y)
Here the given point:
N(-3, -4)
If reflected:
(-3, 4)
Answer: (-3, 4)
Explanation:
When you reflect a point across the x-axis, the x-coordinate remains the same, but the y-coordinate is taken to be the additive inverse. The reflection of point (x, y) across the x-axis is (x, -y).
(-3, -4) ⇒ (-3, 4)

Answer:
[tex]x=21[/tex]
Step-by-step explanation:
I'm not sure if I understood what the problem is asking for and if the numbers behind 3 are answer choices but the answer would be 21.
3's times table:
[tex]3*1=3[/tex]
[tex]3*2=6[/tex]
[tex]3*3=9[/tex]
[tex]3*4=12[/tex]
[tex]3*5=15[/tex]
[tex]3*6=18[/tex]
[tex]3*7=21[/tex]
Since 3 times 7 equals 21 the following equations involving division with the numbers 3, 7, and 21 would be:
[tex]\frac{21}{7}=3[/tex] [tex]\frac{21}{3}=7[/tex]
