∠A and \angle B∠B are complementary angles. If m\angle A=(6x+29)^{\circ}∠A=(6x+29)

umka2103 [35]

Answer:

Step-by-step explanation:

Complementary angles add up to 90

6x + 29 + x + 5 = 90

6x + x + 29 + 5 = 90

7x + 34 = 90

7x = 90 - 34 {Subtract 34 from both sides}

7x = 56

x = 56/6 {Divide both sides by 6}

x = 8

∠A = 6x + 29

= 6*8 + 29

= 48 + 29

∠A = 77°

A book can be classified as either non dash fiction or fiction. Suppose that 87% of books are classified as fiction. (a) Two b

Mnenie [13.5K]

Answer:

0.7569, 0.5729,0.4371

Step-by-step explanation:

Given that the books are of only two types either non dash fiction or fiction.

Also probability of selecting a fiction = 0.87 = p

X - no of books fiction selected is binomial with p = 0.87 and n =2

(since each trial is independent of the other and there are only two trials)

a) the probability that both books are fiction=

$P(X=2) = 0.87^2 = \\0.7569$

b) Here n =4 with same p.

$P(X=4) =0.87^4 \\= 0.5729$

c) Prob atleast one is non dash fiction = $P(X< 4)\\= 1-P(X=4)\\=1-0.87^4\\=0.4371$

This is not unusual since 0.4371 probability is not nearer to 0 it is almost half.
