A multiple-choice test in which each question has 4 choices only one of which is correct. Assume that 9 questions are answered b

yaroslaw [1]

Answer:

Therefore, the probability is P=0.0084.

Step-by-step explanation:

We know that a multiple-choice test in which each question has 4 choices only one of which is correct. Assume that 9 questions are answered by guessing randomly.

Because we have 4 choices only one of which is correct, we get that p=0.25 and q=0.75.

We calculate the probability of getting exactly 6 correct answers.

n=9 and k=6.

$P=C_k^n\cdot p^k\cdot q^{n-k}\\\\P=C_6^9\cdot 0.25^6\cdot 0.75^3\\\\P=84\cdot 0.0001\\\\P=0.0084$

Therefore, the probability is P=0.0084.

In 2010, the population of a city was 119,000. From 2010 to 2015, the population grew by 6.3%. From 2015 to 2020, it fell by 3.7

kaheart [24]

Step-by-step explanation:

population in 2010=119000

population in 2015=11900*1.063=126497

population in 2020=126497*(1 - 0.037)=126491*0.963= 121817

answer=

$\frac{121817}{11900} \times 100$

=1.0237%
