You could use the proportion 3:1.

Per 3 feet, there is 1 yard.

For every 3 feet, there is an additional yard.

The ratio is 3 to 1, or 3:1

Answer:

1. 2/25

2. 4/15

Step-by-step explanation:

1. P(Y∩X)

Since P(X) =2/3 , P(Y) =2/5 , and P(X|Y) =1/5, this is a conditional probability.

So P(Y∩X) = P(Y)P(X|Y) = 2/5 × 1/5 = 2/25

2. P(Y)· P(X)

P(Y)· P(X) = 2/3 × 2/5 = 4/15

What is 1 and 3/4 as an improper fraction

EastWind [94]

$\huge\boxed{\frac{7}{4}}$

First, turn $1$ into an improper fraction with a denominator of 4, which matches $\frac{3}{4}$ .

$\displaystyle 1 \frac{3}{4} = \frac{4}{4} + \frac{3}{4}$

Now, just add the numerators.

$\displaystyle \frac{4}{4} + \frac{3}{4} = \boxed{\frac{7}{4}}$

If the diameter of the circle below is 16 in., what is the area of the circle?

mote1985 [20]

Answer:

64π inches² (approximately 201.06 inches²)

Step-by-step explanation:

$A=\pi r^2$ where $r$ is the radius

To find the radius, divide the diameter by 2

16 ÷ 2 = 8 inches

Plug in 8 as the radius

$A=\pi (8)^2\\A=64\pi$

$A=201.06$ (approximately)

Therefore, the area of the circle is 64π inches², or approximately 201.06 inches².

I hope this helps!
