Answer:
2nd row, circle is <u><em>6</em><em>x</em><em> </em><em>+</em><em> </em><em>2</em><em>y</em></u><em>.</em>
3rd row, rectangle is <u><em>3</em><em>x</em><em> </em><em>+</em><em> </em><em>y</em></u><em> </em>and circle is <u><em>5</em><em>x</em></u><em>.</em>
Step-by-step explanation:
As the question say when 2 rectangles, at the sides are add up together, it will form circle in the middle. So in order to find circle or rectangle, you either have to add or substract :
For 2nd row, circle,
T/L(r) + B/R(r) = M(c)
4x + 3y + 2x - y = M(c)
6x + 2y = M(c)
M(c) = 6x + 2y
For 3rd row, rectangle,
T/L(r) + B/R(r) = M(c)
x + 4y + B(r) = 4x + 5y
B(r) = 4x + 5y - x - 4y
= 3x + y
For 3rd row, circle,
T/L(r) + B/R(r) = M(c)
2x - y + 3x + y = M(c)
5x = M(c)
M(c) = 5x
* Take note, for 3rd row, you first have to find the rectangle then circle.
Symbols :
- T/L(r) = Top/Left (rectangle)
- B/R(r) = Bottom/Right (rectangle)
- M(c) = Middle (circle)
a. Recall that
For , we have
By integrating both sides, we get
If , then
so that
We can shift the index to simplify the sum slightly.
b. The power series for can be obtained simply by multiplying both sides of the series above by .
c. We have
In one month, there are on average 30 days.
So if he talks 135 minutes per month, he talks on average 135/30 minutes per day
135/30 = 4.5
So on average he talks to his grandfather for 4 minutes and 30 seconds a day.
Answer: Yes.
Step-by-step explanation: Convert it to a decimal. Percent means per 100. So if you have 50% the decimal form is .5 since you divide 50 by 100. 5% would be .05 etc
Answer:
It's exactly normal, because both populations are normally distributed.
