Answer:

No, it is not possible.

Step-by-step explanation:

The Triangle Sum Theorem states that all the interior angles of a triangle will always add up to 180°, but 150 + 20 + 20 = 190.

Find the distance between the pair of points (-6.-17) and (-8.-19) The distance is (Round to the nearest thousandth as needed.)​
valina [46]

Answer:

2.83

Step-by-step explanation:

d= Square root of (x2 - x1 )^2 +( y2- y1)^2

from the point given you

x1= -6

y1 = -17

x2 = -8

y2 = -19

by applying the formula

Square root of ( -8 - (-6))^2 + ( -19 - (-17))^2

Square root of (-8+6) + (-19+17)^2

Telemarketing. the probability that a call will reach a live person is 0.2. the calls are independent. (a) a telemarketer places
Sergeeva-Olga [200]

Solution: Telemarketing. the probability that a call will reach a live person is 0.2. the calls are independent. (a) a telemarketer places 5 calls. what is the probability that none of them reaches a live person.

Answer: The given random experiment can be considered as binomial experiment with probability of success = 0.2 and number of trials = 5

Therefore, we have:

n=5,p=0.2,q=(1-p)=1-0.2=0.8

Let x be the number calls that reach to live person.

We have to find P(x=0)

Using the binomial probability distribution, we have:

P(x=0)=\binom{5}{0}0.2^{0} (1-0.2)^{5-0}

                 =1 \times 1 \times 0.8^{5}

                 =0.3277

Therefore, the probability that none of them reaches a live person is 0.3277
