Same question was posted earlier .... I repeat my answer here ...

Question (2a):
Given that sum of triangle = 180°
∠1 + ∠2 + ∠3 = 180°
∠3 = 180° - ∠1 - ∠2     ---------------- (1)

Given that sum of angles on the adjacent line = 180°
∠3 + ∠4 = 180° 
∠4  = 180° - ∠3 ------------------------(2)

Sub (1) into (2)
 ∠4  = 180° - (180° - ∠1 - ∠2 ) 
∠4  = 180° - 180° + ∠1 +∠2  
∠4  =  ∠1 +∠2  (proven)

Question (2b):
∠4  =  52° + 25° 
∠4  =  77°

olga55 [171]

Answer:

(507.05, 592.95)

Step-by-step explanation:

Given data:

sample mean = $550, sample standard deviation S = $60.05

95% confidence interval , n = 10

For 95% confidence interval for the mean

mean ± M.E.

where M.E. is margin of error = t_{n-1}, \alpha/2\times\frac{S}{\sqrt{n} }

Substituting the values in above equation

=t_{10-1}, 0.05/2\times\frac{60.05}{\sqrt{10} }

= 2.62×18.99

=42.955

= 550±42.95

=(507.05, 592.95)

This is the 4th question
gavmur [86]

Answer:

a) There are 9 outcomes.

b) **i have attached the tree diagram**

c) 1/9

d) 1/9

Step-by-step explanation:

Both events (choosing a shirt and choosing pants) are not mutually exclusive (disjoint). Meaning that both events can occur at the same time.

a) For a sequence of two events in which the first event can occur <em>m</em> ways and the second event can occur <em>n</em> ways, the events together can occur a total of <em>m</em> • <em>n</em> ways. So for this problem, you would do 3 • 3 which equals 9.

b) **tree diagram is attached**

c) Because there are two different events occurring (choosing a shirt and choosing pants) you need to multiply using the Multiplication Rule for Independent Events : P(A and B) = P(A) * P(B)

The probability of event A occurring (choosing a red shirt) is 1/3 and the probability of event B occurring (choosing brown pants) is also 1/3.

1/3 * 1/3 = 1/9

d) You would do the same thing here as part c.

The probability of event A occurring (choosing a blue shirt) is 1/3 and the probability of event B occurring (choosing blue pants) is again 1/3.

1/3 * 1/3 = 1/9

I hope this was helpful!! :)
