Answer:
95.4% of family vehicles is between 1 and 3 years old.
Step-by-step explanation:
We are given the following information in the question:
Mean, μ = 2
Standard Deviation, σ = 6 months = 0.5 year
We are given that the distribution of age of cars is a bell shaped distribution that is a normal distribution.
Formula:
P(family vehicles is between 1 and 3 years old)
95.4% of family vehicles is between 1 and 3 years old.
By definition of , we have
and we deduce
Now, recall that the diameter is twice the radius:
and solve for :
So, divide the circumference by and you'll find the radius.
You multiply 8 by 1 because if you round up it will be an estimate
8 x 1 = 8
So Kim is wrong
24 hours in a day
24 divided by 8 = 3
400 mg times 3 doses = 1200 mg a day
mg to ounce is times 3.5274 x 10^-5
1200 times 3.5274 x 10^-5 = 0.0423288 oz
Answer:
B.
Step-by-step explanation:
Let's use the slope equation first. The slope equation is as follows:
This is what is given in the equation:
Let's label each component of the equation using these points:
y2 = 9
y1 = 7
x2 = 6
x1 = 3
Now, plug these into the equation
We can now eliminate A and C of the answer choices.
Now let's find the y intercept
Right now we have the following equation
In order to find the y intercept we need to plug in one of the given points into the equation. Let's use point (3,7).
The equation should look like this now:
Now lets solve for the y-intercept
Now that we found the y-intercept is 5 we have our full equation!
