It is the third number line.
b-11=-8
What minus 11 would equal -8? 3!
8+3=11 so it would make sense that the dot would be on 3.
smaller numbers minus larger numbers (such as this equation) always end up being negative, so if you have the answer and at least one of the other numbers, it will be easy to figure out.
In this case you would want to maybe just imagine 11-8=? or go 8+?=11.
11-8=3 and 8+3=11. There you would have your missing number.
Answer:
0.1091 or 10.91%
Step-by-step explanation:
We have been given that a particular telephone number is used to receive both voice calls and fax messages. suppose that 20% of the incoming calls involve fax messages and consider a sample of 20 calls. We are asked to find the probability that exactly 6 of the calls involve a fax message.
We will use Bernoulli's trials to solve our given problem.
Therefore, the probability that exactly 6 of the calls involve a fax message would be approximately 0.1091 or 10.91%.
Answer: (x - 1)² + (y - 1)² = 25
<u>Step-by-step explanation:</u>
The formula for a circle is (x - h)² + (y - k)² = r² where
- (h, k) is the center
- r is the radius
Typically, you are given the center and the radius. In this problem, you are given (x, y) so you must plug that into the equation to find r².
Given: (x, y) = (-3, 4) and (h, k) = (1, 1)
(-3 - 1)² + (4 - 1)² = r²
(-4)² + (3)² = r²
16 + 9 = r²
25 = r²
Next, input (h, k) and r² into the equation
(x - 1)² + (y - 1)² = 25
Answer:
116 mg
Step-by-step explanation:
From the statement we have that a patient receives 1 1/3 mg of medicine per kilogram of his weight.
The first thing is to pass the mixed number 1 1/3 to a rational number, like this:
1 + 1/3 = 1.33
So it would be 1.33 mg of medicine per kg, if the patient weighs 87 kg, he should be given a total of:
1.33 * 87 = 116
A total of 116 mg should be given to that patient.
Answer:
See below.
Step-by-step explanation:
The area of the circle is given by the formula:
From the circle, we can see that the diameter is 14. Thus, the radius must be 14 divided by 2 or 7.
We're also using 3.14 for π. Substitute:
Use a calculator:
And we're done!
