Answer:
The correct option is B. 23%
Step-by-step explanation:
Let the event that patient brushes his teeth at least twice a day is denoted by A
So, P(A) = 0.83
Let the event that patient flosses daily is denoted by B
So, P(B) = 0.47
Now, it is given that 19 percent patients brush at least twice a day and floss daily.
⇒ P(A and B) = 0.19
Now, we need to find conditional probability of occurring event B given A has occurred.
Hence, Nearest required percentage = 23%
Therefore, The correct option is B. 23%
Answer: $35.35
Step-by-step explanation:
Facts
3 items
item 1: 8.95
item 2: 11.49
item 3: 12.75
6.5% sales tax
Step 1: Find the total cost of the items ,before tax
8.95+11.49+12.75= 33.19
Step 2: Apply the sales tax
6.5% of 33.19 = 2.15735 --> approximatley $2.16
Step 3: Add the sales tax amount to the total cost of the items to find the final total cost.
$33.19+$2.16= $35.35
Hence the answer is B

Answer:
(x-2)^2+ (y+3)^2 = 64
Step-by-step explanation:
We can write the equation of a circle as
(x-h)^2+ (y-k)^2 = r^2
Where (h,k) is the center and r is the radius
(x-2)^2+ (y- -3)^2 = 8^2
(x-2)^2+ (y+3)^2 = 8^2
(x-2)^2+ (y+3)^2 = 64

Answer:
First, we put the values of the given point into the general equation, giving:
0 = m * -1 + b .......(1)
Now plug in the given value of m into equation (1), giving:
0 = 2 + b ........(2)
Solving equation (2), we find that b = -2.
Now we can write the required equation as:
y = -2x - 2
