Answer:

The answer to your question is 50 inches

Step-by-step explanation:

Data

Area = 200 in²

diagonal 1 = 8 in

diagonal 2 = ?

Formula

Area = (diagonal 1 x diagonal 2) / 2

Solve for diagonal 2

diagonal 2 = 2 x Area 2 / diagonal 1

-Substitution

diagonal 2 = 2 x 200 / 8

-Simplification

diagonal 2 = 400 / 8

-Result

diagonal 2 = 50 in

The rectangle below has an area of 81- x^2 square meters and a width of 9 - x meters

sveta [45]

Answer:

The width would be 9 + x

Step-by-step explanation:

In order to find this, we must first factor the area. This will give us two things that are being multiplied together.

81 - x^2 = (9 - x)(9 + x)

Since the area is the length times the width and the width is x - 9, we know the length must be x + 9

Suppose C1;C2;C3 are three didifferent biased coins, whose probability of heads equals 0.4, 0.5, and 0.2 respectively. Suppose c

allochka39001 [22]

Solution :

$P(A \cap B) = P(\text{coin}\ C_1 \text{ chosen and 4 heads in 10 trails})$

$= \frac{1}{3} \times ^{10}C_4 \times 0.4^4 \times 0.6^6$

= 0.0836

P(B)= P(coin $C_1$ chosen and 4 heads in 10 trails) + P(coin $C_2$ chosen and 4 heads in 10 trail) + P(coin $C_3$ chosen and 4 heads in 10 trail)

$=\frac{1}{3}\times ^{10}C_4 \times 0.4^4 \times 0.6^6 + \frac{1}{3}\times ^{10}C_4 \times 0.5^4 \times 0.5^6 + \frac{1}{3}\times ^{10}C_4 \times 0.2^4 \times 0.8^6$

$=0.0836+0.0684+0.0294$

$=0.1813$

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

$=\frac{0.0836}{0.1813}$

$=0.4611$
