Answer: The answer is most likely 0.3
Step-by-step explanation:
The difference between the theoretical and experimental probabilities of getting heads is 0.3.
This question is solved using the concepts of theoretical and experimental probabilities.
Theoretical probability: Calculated without considering previous trials. Experimental probability: Calculated considering previous trials.----------------------------
Theoretical probability:
A fair coin means that it is equally as likely to be heads or tails, so 0.5 theoretical probability of getting heads.
----------------------------
Experimental probability:
Out of 10 trials, 2 resulted in heads, so 2/10 = 0.2 experimental probability of getting heads.
----------------------------
Difference:
0.5 - 0.2 = 0.3
The difference between the theoretical and experimental probabilities of getting heads is 0.3.

A rope weighs 800 grams per meter of length. What is the weight in kilograms of 12.2 meters of the rope?
Answer: the weight in kilograms is 9.76kg
Step-by-step explanation:
1 meter of length of rope = 800 g
12.2 meters of the rope= (12.2meters x 800g)/ 1 meter=9760grams
We know that 1000 g = 1kg
9760 grams = 9760/1000=9.76 kilograms

Penny’s backyard contains a flower garden. The dimensions of the actual garden are 5 feet by 7½ feet. A scale drawing of the flower garden is shown below.
1. What is the scale factor from the actual flower garden to the scale drawing?
Be sure to express your ratio in simplest form.
2. If the drawing is enlarged by a scale factor of 5/2, what would be the dimensions of the flower garden in the new scale drawing? Express your dimensions in decimal form. Enter the smaller of your two lengths in the first answer box.
inches x
inches
3. What is the scale factor from the actual flower garden to the new scale drawing?
Be sure to express your ratio in simplest form.
Answer:
1.) Scale factor from the actual flower garden to the scale drawing = 20 : 1
2.) Dimensions of the flower garden in the new scale drawing = 7.5 inches × 11.25 inches
3.) Scale factor from the actual flower garden to the new scale drawing = 8:1
Step-by-step explanation:
Given - Penny’s backyard contains a flower garden. The dimensions of the
actual garden are 5 feet by 7½ feet. A scale drawing of the flower
garden is 3 inches by 4.5 inches.
To find - 1. What is the scale factor from the actual flower garden to the
scale drawing?
2. If the drawing is enlarged by a scale factor of 5/2, what would
be the dimensions of the flower garden in the new scale
drawing?
3. What is the scale factor from the actual flower garden to the
new scale drawing?
Proof -
As we know that,
1 feet = 12 inches
⇒5 feet = 5×12 = 60 inches
7½ (= [tex]\frac{15}{2}[/tex]) feet = [tex]\frac{15}{2}[/tex]×12 = 90 inches
∴ we get
The dimensions of the actual garden is 60 inches by 90 inches.
1.)
As,
[tex]\frac{60}{3} = \frac{20}{1} = 20 : 1[/tex]
[tex]\frac{90}{4.5} = \frac{900}{45} =\frac{20}{1} = 20 : 1[/tex]
So,
Scale factor from the actual flower garden to the scale drawing = 20 : 1
2.)
As given, If the drawing is enlarged by a scale factor of 5/2
⇒Dimensions of flower garden = 3×[tex]\frac{5}{2}[/tex] inches by [tex]4.5 (\frac{5}{2})[/tex] inches
= 7.5 inches by 11.25 inches
∴ we get
Dimensions of the flower garden in the new scale drawing = 7.5 inches × 11.25 inches
3.)
Scale factor from the actual flower garden to the new scale drawing = [tex]\frac{60}{7.5}[/tex] = [tex]\frac{600}{75} = \frac{8}{1} = 8 : 1[/tex]

If £25 = 450 rubles, how many £ are in 864 rubles?
Answer:
£48
Step-by-step explanation:
£25 = 450 rubles
We need to know how many rubles you can get from £1.
£25 = 450
£ = 450/25
£ = 18
So, with £1 you get 18 rubles.
To know how many £'s you would need for 864 rubles, you need to divide 864 by 18.
£ = 864/18
£ = 48

Answer:
17. x=11 18. x=18
Step-by-step explanation:
For 17, 14x-25=129, add 25 to 129 to get 154, then divide 154 by 14x to get x=11. The conditional for 17. would be "If J║K then alternate interior angles are congruent.
For 18. 2x-8+9x-10=180, combine like terms to get 11x - 18 =180, add 18 to 180 to get 198 than divide 198 by 11x and get x = 18. Converse statement would be, "If J║K then consecutive interior angles are supplementary.

Avery's mother wants to order large pizzas for Avery's birthday party. Each pizza will be cut into 8 slices. She needs enough pizza for 18 children and 5 adults. She wants each person to have 4 slices. How many pizzas does she need to order?
Answer:
She would need to order 11.5 pizzas. But of course she wouldn't order 11.5 so she'll just round up and order 12 pizzas.
Step-by-step explanation:
Take 4 pieces of pizza for each person and multiply that by how many people there are in this case 23. The answer would be 92 pieces of pizza would be needed to feed all of the 23 people. So you take 92 and divide it by 4 because each person gets 4 slices and the answer you get is 11.5. If the question is a multiple choice and it gives you the option of 11.5 then that's the answer but if its a fill in then round up to 12 pizzas because if not there will not be enough pizza for everyone.
Hope this helped! :)

You have $75 and need to buy 9 books at the bookstore and each book costs d dollars.
Write an algebraic expression to represent the amount of money left over.
Answer:
75-9d
Step-by-step explanation:
Hello,
The Answer to the question is 75-9d let me explain why,
you are asking, how much money is leftover. For me to get that I need to know that for every book it cost "d" dollars.
You know you have $75, and you need 9 books, we don't know how much they cost but we don't really need to.
75 - 9d
75 is the total. You need to subtract it by how many books your buying, 9.
The books are d amount of dollars, so we put 9d so that we know that for every 1 book it cost d amount so technically 9 is the amount of books times d, how much 1 book costs
Hope you can understand, I was having some trouble finding a way to explain it so my bad.
Also, I haven't done that in a while so sorry if I'm wrong

Classify the pair of angles.
O adjacent
O complementary
O supplementary
Onone of these
The pair of angles are acute angles.
The correct option is none of these.
What is an angle?The angles between two lines are the angles formed by two intersecting lines, measured in degrees or radians.
Several different types of angles can be formed between two lines, including acute angles, right angles, and obtuse angles.
We have,
The pair of angles of 30 and 30 are equal in measure.
But they are not adjacent, as they do not share a common vertex and a common side.
They are also not complementary, as complementary angles add up to 90 degrees, and 30 + 30 = 60.
Similarly, they are not supplementary, as supplementary angles add up to 180 degrees, and 30 + 30 = 60.
Therefore,
The pair of angles are none of the given options.
