Answer:

ABD = 49 DEGREES

CBD = 28 DEGREES

Step-by-step explanation:

Add ABD AND CBD equations TOGETHER

8x+5=77

Subtract 5 both sides.

8x=72

x=9

Now you have x, this isn't all you have to do, put x into the equations you have.

3(9)+22=?

27+22= 49

ABD = 49 degrees

5(9)-17=?

45-17= 28

CBD = 28 degrees

to check work, 49 + 28 = 77

P( $r$ successes in $n$ trials) = ⁿ $C_{r}$ × $[P(Success)^{r}]$ × $[P(failure)]^{n-r}$

We have
$n=8$
$r=2$
$P(Success)=0.15$
$P(Failure)=0.85$

Substitute these values into the formula, we have
P( 2 success in 8 trials) = ⁸C₂ × (0.15)² × (0.85)⁶
P( 2 success in 8 trials) = 0.2376.... ≈ 0.24 = 24%
