3*10^7 routers will be needed for 9 billion devices

Step-by-step explanation:

Given

Total Devices = 9\ billion =  9*10^9\ devices\\

1 router supports 300 devices

So we have to divide the total number of devices by the devices supported by 1 router to find the number of routers

So,

Total\ number\ of\ routers= \frac{Devices}{Devices\ with\ one router}\\=\frac{9*10^9}{300}\\=\frac{900*10^7}{300}\\=3*10^7\ routers

Hence,

3*10^7 routers will be needed for 9 billion devices

If the correlation coefficient between two variables is .90, what percent of the variance is explained by this correlation
ZanzabumX [31]

Answer:  81% of the variance in dependent variable is explained by this correlation .

Step-by-step explanation:

For X = Independent variable and Y=dependent variable,

If r= correlation coefficient , then we say r^2<em>  </em>of the<em> </em>variance in Y is explained by Variable X.

Given: r= 0.90

(0.90)^2= 0.81

So, 81% of the variance in dependent variable is explained by this correlation .

Plz someone help I will mark brainlest diameter is 8.8 yd​
sweet [91]

Answer:

60.79 square yards.

Step-by-step explanation:

d = 2r; d = 8.8.

8.8 = 2r

r = 8.8 / 2

r = 4.4 yards.

Since we now have the radius, we can find the area of the circle, which can be found using πr^2, or 3.14 * r^2.

4.4^2 * 3.14 = 19.36 * 3.14 = 60.7904.

Since the question tells us to round to the nearest hundredth, our final answer will be 60.79 square yards.

Hope this helps!
