Step-by-step explanation:
Answer:
At x=3 the value of the function is 4
Step-by-step explanation:
we have the points
(-2,3) and (3,4)
That means
(-2,3)
For x=-2
The value of the function y is equal to 3
(3,4)
For x=3
The value of the function y is equal to 4
therefore
At x=3 the value of the function is 4
The value of p(1) is 2
<h3>What is the value of p(1)?</h3>
The function definition is given as:
P(x) = -3(x - 2)^2 + 5
The expression P(1) means that x =1
So, we have:
P(1) = -3(1 - 2)^2 + 5
Evaluate the difference
P(1) = -3(-1)^2 + 5
Evaluate the square
P(1) = -3 * 1 + 5
This gives
P(1) = 2
Hence, the value of p(1) is 2

<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.
