The probability that exactly 8 individuals do not cover their mouth is 0.0037.
<h3>How to calculate the probability?</h3>
It should be noted that the probability will be solved by using the binomial distribution.
From the information, the probability that a randomly selected individual will not cover his or her mouth when sneezing is 0.267.
Therefore, the probability that thee person will not cover their mouth will be:
= 1 - 0.267
= 0.733
This will be:
= 12C8 × (0.267)^8 × (1 - 0.267)⁴
= 12C8 × (0.267)^8 × 0.733⁴
= 495 × 0.00002582 × 0.28867
= 0.0037
In conclusion, the probability is 0.0037.

Answer:
y = -x - 1
Step-by-step explanation:
First, we can put the equation into y = mx + b form:
2x + 5y = 10
5y = -2x + 10
y = -x + 2
Now, we know the slope is -. A parallel line will have the same slope.
So, we can plug in the point (-5, 1) into the equation y = -x + b to find b:
1 = -(-5) + b
1 = 2 + b
-1 = b
So, the equation will be y = -x - 1
Answer:
The triangles are similar in that the smaller triangle was dilated by a scale factor of 1/4 which means that the length of the missing side is 20m
Step-by-step explanation:
Answer:
EF = 10
Step-by-step explanation:
DE + EF = DF
5x + x + 8 = 20
6x = 20 - 8
6x = 12
x = 12/6
x = 2
EF = x + 8 = 2 + 8 = 10
