2. Suppose a coin is flipped 10,000 times. What is a reasonable prediction for the number of times the coin lands on tails?

Set up a proportion and solve. Your response will be a number. No label.

Answers

Answer 1

Answer:

Step-by-step explanation:

1)8/36 x 180= 40 bags

2) im guessing its 0.5 x 10,000=5000

Answer 2

Answer:

1) 40

2) 5000

Step-by-step explanation:

QUESTION 1

8:36 = x:180

180/36 = 5

8(5) = x

40 = x

therefore they will screen 40 bags in a group of 180

QUESTION 2

A coin has 2 sides, heads and tails.  

So it has a 50% chance of getting heads or tails

50% of 10 000 is 5000

it could land on tails 5000 times and heads 5000 times

hope this helped

At a basketball game, a vender sold a combined total of 124 sodas and hot dogs. The number of hot dogs sold was 54 less than the number of sodas sold. Find the number of sodas sold and the number of hot dogs sold

Answers

x+y=124. y=x-54. 124= x + x-54. add 54. 178= x+x or 178=2x. divide each side by 2. x=89. 124-89=35. 89 sodas and 35 dogs

There were 89 sodas and 35 hot dogs sold.

What is an equation?

The equation is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are equal.

Let the number of sodas would be x and the number of hot dogs would be y

x + y = 124 ....(i)

y = x - 54   ....(ii)

Substitute the value of equation (ii) in (i), and solve for x

124 = x + x - 54

Add 54 to the above equation, and we get

178 = x+x or

178 = 2x.

Divide each side by 2 into the above equation, and we get

x = 89

Substitute the value of x = 89 in equation (i), and solve for y

y = 124 - 89

y = 35

Hence, There were 89 sodas and 35 hot dogs sold.

Answer:

It would be A because to do experimental probability you have to add the total amount out trials and that would be the denominator and the number of times 3 happened would be the numerator.

It would be A number 1 because I think that is what it is.

Answer:. x=16°

4x=85-21. (move x-es in one side and known numbers in another side)

4x=64°. (subtract)

Step-by-step explanation:

h-9=7

h=9+7

h=16

I hope this helps.

Answer:

H=16

Step-by-step explanation:

H is a variable representing an unknown number. What you would do for this equation is:

Start with a number like 10, and plug it into the eqation where h is, 10-9=7

We know that is a false statement. So since 10-9=1, all you do is think what plus one equals 7. 1+6=7 so take 6 and add it to 10. Replace the variable h with 16. 16-9=7

That is correct, so H=16.

Answer:

-3/4^10

Step-by-step explanation:

you multiply powers 5 and 2

-3/4 ^10

Answer:

The answer is 22

The sum of two numbers is 48:

x + y = 48      ⇒ x = 48 - y

One third of one number is 5 greater than one sixth of another number:  

1/3x =5  + 1/6 y    

1/3(48 - y) = 5 + 1/6y

1/3 * 48 - 1/3 * y = 5 + 1/6 y

16 - 1/3y = 5 + 1/6y

16 - 5 = 1/6y + 1/3y

11 = 1/6y + 2/6y

11 = 3/6y

y = 11 * 6 / 3

y = 22

x = 48 - y

x = 48 - 22

x = 26

The smallest number is 22.

Answers

An orchard sells 1102.5 pounds of apples in 1 week.

Answer:

612.5

Step-by-step explanation:

First you have to find how many pounds of apples it sells daily. 3.5 * 25 = 87.5. Then you would multiply by 7 to find how many pounds it sells in a week. 87.5 * 7 = 612.5. So the orchard sells 3.5 pounds of apples per week.
