Mathematics
1 answer:
shepuryov [24]3 years ago
3 0

Answer:

11

Step-by-step explanation:

Pulg in 2 into the equation x+3^2

I dont know if theres supposed to be a parenthese like (x+3)^{2} but if there isn't then it would be 2+3^{2}  which is 2+9

if there is parenthese... it would be:

(2+3)^{2} = (5)^{2}=25

It would be letter D - 3648.

The probability of winning is 0.76 and the probability of losing is 0.24.

In each simulation the probability of winning exactly one match is:   P(win one match) = 2C1 x 0.76 x 0.24 = 0.3648

Multiply the result by 10,000 simulations to get the expected number of times that exactly one match is won.
   10,000 x 0.3648 = 3648 times.

In AABC, MLA = 53, m4C = 84, and side a = 8 inches. Find the length of side b to the nearest tenth of an inch.
Cerrena [4.2K]

Answer:

6.8 inches

Step-by-step explanation:

Given data :

m∠ A = 53°  ,  m∠ C = 84° , side a = 8 inches

therefor m ∠ B = ( 180 - (84 + 53 )) = 43°

<u>Find the length of side b </u>

we will apply sine rule here

\frac{a}{sinA} = \frac{b}{sinB} = \frac{c}{sinC}

= \frac{8}{sin53}  = \frac{b}{sin43}

∴ b = ( sin43° * 8 ) / sin53°

      = ( 0.6819 * 8 ) / 0.7986

      = 5.4552 / 0.7986 = 6.83 ≈ 6.8 inches
