A and B are independent events if the probability of getting a red convertible is 0.08

<h3>How to determine the probability?</h3>

The given parameters are:

P(A) = 0.20

P(B) = 0.40

The events are independent, if

P(A and B) = P(A) * P(B)

So, we have:

P(A and B) = 0.20 * 0.40

Evaluate

P(A and B) = 0.08

Hence, A and B are independent events if the probability of getting a red convertible is 0.08

Answer:

area= 59.5 perimeter=31.6

Step-by-step explanation:

the area of the square is 49 because 7x7=49 and the area of the triangle is 3x7/2 because it is half of a rectangle so it is 10.5 + 49 = 59.5 and perimeter you add all the sides so 3+7.6+7+7+7= 31.6

Answer:

Step-by-step explanation:

$\frac{2}{k^2-2k}=1-\frac{1}{k^2-2k}$

multiply by $\frac{k^2-2k}{1}$ on each side

$2=k^2-2k-1$

add 1 on both sides $3=k^2-2k$

make it equal 0

$0=k^2-2k-3$

Factor

$(k-3)(k+1)$

answer is 3 and -1

Plzzz hurry up and help me if A+B=45<br>prove that <br>(1+tanA)(1+tanB)=2

Solnce55 [7]

Answer:

see explanation

Step-by-step explanation:

If A +B = 45° then tan(A+B) = tan45° = 1

Expanding (1 + tanA)(1 + tanB)

= 1 + tanA + tanB + tanAtanB → (1)

Using the Addition formula for tan(A + B)

tan(A+B) = $\frac{tanA+tanB}{1-tanAtanB}$ = 1 ← from above

Hence

tanA + tanB = 1 - tanAtanB ( add tanAtanB to both sides )

tanA + tanB + tanAtanB = 1 ( add 1 to both sides )

1 + tanA + tanB + tanAtanB = 2

Then from (1)

(1 + tanA)(1 + tanB) = 2 ⇒ proven
