<h2>
The required probability is 0.1224.</h2>
Step-by-step explanation:
Here, given:
The probability of having 0 dental checkup = 0.3
The probability of having 1 dental checkup = 0.6
The probability of having 2 dental checkup = 0.1
Number of people chosen at random = 7
So, the number of ways 2, 4 and 1 checkup are :
Now, the combined probability that two will have no checkups, four will have one checkup, and one will have two checkups in the next year
=
Hence, the required probability is 0.1224.
Answer:
B.45
Step-by-step explanation:
<h3>A sum of all angles in a triangle is 180°</h3><h3>55+60+x+20=180</h3>
60+55=115
180-115=65
65-20=45
Answer: 45°
Your answer is B) -5/6.
We can find this using the formula (y2 - y1)/(x2 - x1) and substitute in the coordinates:
(-2 - 3)/(5 - -1) = -5/6
I hope this helps!
Answer:
there is no value of x that will make this equation true
No. 10 ft border is not enough.
To find out the enough length to border needed to exactly border the bulletin board, we must find out the perimeter of the bulletin board.
Perimeter of a rectangle = Length*(2) + Width*(2)
= (4 ft *2) + (2 ft *2)
= 12 ft
So, 10 ft is not enough because the perimeter of the bulletin board is 12 ft.
