Answer: Probability of the arrow landing on a green colored section is \dfrac{1}{4}

Step-by-step explanation:

Since we have given that

Probability of the arrow landing on a section colored blue = \dfrac{6}{20}

Probability of the arrow landing on a section colored red = \dfrac{9}{20}

Since there are only three sections i.e. red, blue and green.

We need to find the probability of the arrow landing on a section colored green.

Required probability is given by

1-(\dfrac{9}{20}+\dfrac{6}{20})\\\\=1-\dfrac{15}{20}\\\\=\dfrac{20-15}{20}\\\\=\dfrac{5}{20}\\\\=\dfrac{1}{4}

Hence, Probability of the arrow landing on a green colored section is \dfrac{1}{4}

The answer would be 5/20 because you add the probability of red and blue (15/20), then subtract from the total (20) which would make it 5/20.

The ratio of the sides will be constant. Then the value of the length of line segment SA will be 3 ft.

The missing diagram is given below.

<h3>What is the triangle?</h3>

A triangle is a three-sided polygon with three angles. The angles of the triangle add up to 180 degrees.

The triangles ΔABC and ΔSBT are the similar triangles.

Then the ratio of the sides will be constant.

BS / SA = BT / TC

10 / SA = 9 / 2.7

      SA = 3

Then the value of the length of line segment SA will be 3 ft.

More about the triangle link is given below.

Four int variables, x1, x2, y1, and y2, have been declared and been given values. write an expression whose value is the differe
Katen [24]
Even though we are using variables, we still know that "difference" means subtraction. So, if the larger is x1 and x2, those variables go first. The smaller, y1 and y2 will go second. So our problem will look like this:

(x1 <  x2 ? x2 : x1) - (y1 < y2 ? y1 : y2)
