Answer:

236.715 ft²

Step-by-step explanation:

The figure consists of the rectangle with sides 15 ft and 4 ft and two semicircles with diameter 15 ft (radius 7.5 ft).

The area of the rectangle is

A₁=15·4=60 ft²

The area of two semicircles together is the area of circle. Thus,

A₂=πr²=π·7.5²=56.25π≈176.715 ft²

The area of the figure is

A=A₁+A₂=60+176.715=236.715 ft²

We can use the slope formula to find the slope.

$\frac{y.2 - y.1}{x.2 - x.1} = m$

2 + 5 / 4 - 0

7/4

The slope is 7/4, or 1.75

The Venn diagram shows the results of two events resulting from rolling a number cube.

lorasvet [3.4K]

Answer:

Option B.

Step-by-step explanation:

From the given venn diagram it is clear that

$A={1,2}$

$B={1,2,3,4,5,6}$

$A\cap B={1,2}$

Since the intersection of A and B is non-empty, therefore by conditional probability

$P(B|A)=\dfrac{P(A\cap B)}{P(A)}$

$P(B|A)\cdot P(A)=P(A\cap B)$

$P(A\cap B)=P(B|A)\cdot P(A)$

Therefore, the correct option is B.
