Answer: 0.001 or 1/1000
Since it is a negative exponent and -3 so it is in the thousandths, so 1/1000 or 0.001.
Have a good day! : )
Hello,
a(1)=108
a(2)=a(1)/(-2)=-54
a(3)=a(2)/(-2)=a(1)/(-2)²=27
a(4)=a(3)/(-2)=a(1)/((-2)^3)=-27/2
a(n)=a(1)/(-2)^(n-1)=108 *(-1/2)^(n-1) (exponential decreasing)
lim if x->infinite (a(n))=0==> converges
We know the opposite and adjacent sides of angle B, so we can use the inverse tangent to solve for its value.
tan(B)^-1 = 3/4
B = 64.4 degrees
Answer:
The mean is <em>c). 67</em>
Step-by-step explanation:
You must use the weighted average in order to calculate the mean, given that we know the frequency distribution.
In order to to this, you calculate the proportion that the frequency on each interval represents out of the total frequencies; in other words, this is the weight value:
These are the factors by which you will multiply the speed so that you can get the average speed in terms of their weight. For each interval of speed, let's take the average between the minimum and the maximum as the value of speed.
After these two transformations, your table will look as this:
Then, you multiply the average speed times its weight value, finding the weighting factor:
The final step is to sum all the weighting factors, which gives you a total of 67 mph. This is your weighted average.
Answer:
y = (x - )² -
Step-by-step explanation:
Given
y = (x + 2)(x - 3) ← expand factors
= x² - x - 6
Use the method of completing the square
add/ subtract ( half the coefficient of the x- term )² to x² - x
y = x² + 2(- ) x + - - 6
= (x - )² -
