Answer: The probability that she will guess correctly on the third question =\frac{1}{4}


Step-by-step explanation:

Given: The math test has 10 multiple choice questions, each with 4 answers.

To find  probability that she will guess correctly on the third question, we need to just look at only one question which has 4 options and one of them is the right answer, thus probability of choosing the right answer from 4 option is the fraction of 1 over 4.

The probability that she will guess correctly on the third question

=\frac{\text{answer of a question}}{\text{total options of a question}}

=\frac{1}{4}

Dina planted a six-foot tree in her backyard which she expects to grow at the rate of 4 feet per year. Find the equation of the
Scrat [10]

Answer:

y = 6 + 4x

After 4 years, the tree would be 22 ft tall.

Step-by-step explanation:

Hi there!

Let x = the number of years that pass

Let y = the height of the tree (ft)

We're given that the 6-foot tree grows at a rate of 4 ft per year. This means that the height of the tree will be equal to 6 ft, the original height, plus another 4 ft every year that passes.

Height of tree = 6 feet + 4 feet × number of years that pass

y = 6 + 4x

To solve for how tall the tree would be 4 years after Dina plants it, replace x with 4, since 4 years have passed:

y = 6 + 4(4)

y = 6 + 16

y = 22

Therefore, the tree would be 22 ft tall.

I hope this helps!

The price of a swimming pool
Goryan [66]

Answer:

  • Sales\:\:Price=List\:\:Price-Discount
  • Sales price= $1167.25 List price=L Discount=19.5\%\:of\:L=0.195L
  • 1167.25=L-0.195L

Step-by-step explanation:

The percentage discount is 19.5\%

The discount is always given on the list price.

Sales\:\:Price=List\:\:Price-Discount

Let the list price be L, then

List price=L

Sales price= $1167.25

Discount=19.5\%\:of\:L=0.195L

We substitute into the equation to get:

1167.25=L-0.195L

1167.25=0.805L

Divide both sides by 0.805

\frac{1167.25}{0.805}=L

1450=L

The list price of the swimming pool is $1450
