If a/b = c/d, then ad = bc.

Nikolay [14]

Answer:

The statement is true

see the explanation

Step-by-step explanation:

we have the proportion

$\frac{a}{b}=\frac{c}{d}$

we know that

To solve the proportion multiply in cross

$(a)(d)=(b)(c)$

$ad=bc$

therefore

The statement is true

After a rotation of 90° about the origin, the coordinates of the vertices of the image of a triangle are A'(6,3), B'(-2, 1)

Fed [463]

Answer:

A(3, -6)
B(1, 2)
C(7, -1)

Step-by-step explanation:

Rotation by -90° about the origin is the transformation ...

(x, y) ⇒ (y, -x)

So, your pre-image points are ...

A'(6, 3) ⇒ A(3, -6)

B'(-2, 1) ⇒ B(1, 2)

C'(1, 7) ⇒ C(7, -1)

Hotels, like airline, often overbook, counting on the fact that some people with reservations will cancel at the last minute. A

agasfer [191]

Answer: The required probability is 0.334.

Step-by-step explanation:

Since we have given that

N = 15 reservations

probability of reservations will not be used = 0.2

probability of reservations will be used = 1-0.2=0.8

Let X be the Binomial variable,that the number of reservations canceled.

We need to find the probability that more than 8 but less than 12 reservations.

So, it becomes,

$P(8$

Hence, the required probability is 0.334.

If f(x) varies directly with x2, and f(x) = 96 when x = 4, find the value of f(2).

Scilla [17]

F ( x ) = k * x²
f ( 4 ) = 96
96 = k * 4²
96 = 16 k
k = 96 : 16
k = 6
f ( 2 ) = 6 * 2² = 6 * 4 = 24
Answer: D ) 24
