A coin is tossed several times and the results are displayed in this table.

Heads: 14 Tails: 7

What is the experimental probability of the coin landing on tails?

Enter your answer, as a fraction in simplified form, in the boxes.

Answers

A coin was tossed a total of 21 times.

If we add 7 + 7 + 7 together, we can see that we get 21.

Since 7 + 7 = 14, the probability of getting heads is 2/3.

1 - 2/3 = 1/3, so the experimental probability of the coin landing on tails is 1/3.

Step-by-step explanation:

i dont know if this is correct

find the value of x when y equals -7.
2(3x - 7) = 9y​

Answers

Hey there!


2(3x - 7) = 9y

2(3x - 7) = 9(-7)

2(3x - 7) = -63

2(3x) + 2(-7) = -63

6x - 14 = -63

ADD 14 to BOTH SIDES

6x - 14 + 13 = -63 + 13

SIMPLIFY IT!
6x = -63 + 13

6x = -49

DIVISION 6 to BOTH SIDES

6x/6 = -49/6

SIMPLIFY!
x = -49/6

x = -8 1/6


Therefore, the answer should be:

x = -8 1/6 (or x = -49/6 [EITHER OF THOSE SHOULD BE YOUR RESULT BECAUSE THEY ARE BOTH EQUAL TO EACH OTHER])

Answer:

25

Step-by-step explanation:

Let the whole number be W

W x 140% = 35

Percentage to Decimal conversion

Divide % by 100 to get the decimal140/100 = 1.4

Solving

1.4W = 35W = 35/1.4W = 175/7W = 25

Answer:

25

Step-by-step explanation:

We're given:

140% of a number is 35

Let the number be x.

First, convert 140% into a decimal:

1.4

Then, write an equation:

1.4x = 35

x = 35 ÷ 1.4

x = 25

Therefore, 140% of 25 is 35.

4. Each pail of plaster covers 90 square feet of ceiling. What is the least number of pails of plaster you would need to buy to cover the ceiling of a square room with walls 14 feet long?
5 pails
6 pails
4 pails
3 pails

Answers

Answer:

3 pails

Step-by-step explanation:

The square room's base is 14 x 14 = 196

You need to fill the whole room so you might get extra

so... 196 / 90 = 2.177777778

which means you will need  3 and you will have extra

Answer:

3 pails!

Step-by-step explanation:

The area of the ceiling:

A = 14² = 196 ft²

We need plaster to cover 196 ft².

196 : 90 = 2.17778
