Answer:
what is the base and height when you know that you can multiply
Step-by-step explanation:
we are given the data from 9 to 20. we can plot the data in bar graph. The mean of the data is 15. in this case, we plot the number in x and y in terms of frequency. We can see that the plot is evenly distributed at 15 and then also at the extremes. Hence the answer to this problem is C. symmetric
Answer:
1050 + (150)times the amount of jobs they do for you during that winter, for A. 0 + (200)times the amount of jokes they do for you during that winter, for B.
Step-by-step explanation:
Boom I would choose B because it would be cheaper, since we do most of the snow removal ourselves.
Answer:
C and E
Step-by-step explanation:
Recall that according to the complex conjugate theorem, if P(x) is a polynomial function with real coefficients, and a+bi is an imaginary root of P(x), then its conjugate (i.e a-bi) must also be a root.
Here we see that 2 of the given roots are imaginary : i and 2+i
by the theorem given above, the conjugates of these must also be roots
i.e -i and 2-i
Answer:
x = -9
x = 2
Step-by-step explanation:
Given:
First, note that
Since 
and 
stay in the denominator, then
Now add two fractions which stay in the left part. The common denominator is 
so multiply the numerator of the first fraction by 
and the numerator of the second fraction by 
and subtract them in the numerator:
