Answer:

∠1=66⁰

∠2=24⁰

∠3=24⁰

∠4=90⁰

Step-by-step explanation:

∠2=∠ADB=24 (ΔADB is isosceles, so ∠ADB=∠ABD)

∠4 =90 (right angle)

∠3=24 (BD bisects ∠ABC, so ∠2=∠3)

∠1+∠2+90=180 (angles in triangle add to 180)

∠1=66

Answer:

(4x + 3) + (-2x + 4) = 2x + 7

Step-by-step explanation:

(4x + 3) + (-2x + 4) = you then collect like terms

(4x + -2x) + (3 + 4)= like this, and you add what's inside perenthesis

= 2x + (3 + 4). step-by-step

= 2x + 7. then that is how you get =2x+7

Dogs are inbred for such desirable characteristics as blue eye color, but an unfortunate by-product of such inbreeding can be th

Answer:

The probability that the dogs are blue eyed and deaf is 13.02%.

Step-by-step explanation:

We are given the following information in the question:

P(Blue eyes) = 31%

P(Deaf) = 38%

P(Deaf | Blue eyes) = 42%

Formula for conditional probability:

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

Now, let A be the event where the dog is deaf and B be the the event where dog is blue eyed.

$P( \text{ Deaf}|\text{Blue eyes}) = \displaystyle\frac{P( \text{Deaf} \cap \text{Blue eyes})}{P(\text{Blue eyes})}\\\\0.42 = \displaystyle\frac{P( \text{Deaf} \cap \text{Blue eyes})}{0.31}\\\\P( \text{Deaf} \cap \text{Blue eyes}) = 0.42\times 0.31 = 0.1302 = 13.02\%$
