Given a feedlot of about 1200 cows, if an individual cow produces about 50 liters of manure a day, how many liters of manure wou
Amiraneli [1.4K]
Hello!

First you have to find how many liters of manure is made a day

1 cow makes 50 liters a day

We can do 50 * 1200 to find how many liters the cows make a day

50 * 1200 = 60000

Then you multiply this my how many days are in a month

60000 * 30 = 1800000

The answer is 1,800,000 liters of manure a month

Hope this helps!

If sinX = 0.6, and X is in Quadrant II, then what is the value of cosX?
maxonik [38]
To calculate for cos X given that sin X=0.6 and is in Quadrant we proceed as follows:
sin X=0.6
Thus implies that:
x=arcsin 0.6
x=36.97
given that X is in the Quadrant ii then the value of x will be:
180-36.97
=143.13
hence cos X will be:
cos X=cos 143.13
cos X=-0.8

Answer:

The confidence level for a confidence interval of 46.4% to  47.6% is 99.7%.

Explanation:

First of all, the choices for this question are missing so I will include the ones I found for this exact question. The missing options are as follows:

A. 85% B. 95% C. 68% D. 99.7%

When it comes to statistics, a confidence interval (CI) is  a type of interval estimate  of a population parameter. Statistics is all about drawing conclusions in the face of uncertainty. Whenever you take a sample, you can’t be completely certain that your sample truly reflects the population it’s drawn from.

In conclusion, from the choices presented, the best option is the last one. Option D.

A circle is defined by the equation x2 + y2 + 8x + 22y + 37 = 0. What are the coordinates for the center of the circle and the l
inn [45]
We can say that:
8x = -2ax
8 = -2a
a = -4

22y = - 2by
22 = -2b
b = -11

37 = a² + b² - r²
37 = (-4)² + (-11)² - r²
r² = 16 + 121 - 37
r² = 100
r = 10

With all this information, we can say that:
The center of the circle is: (-4 ; -11)
and the radius of the circle is r = 10

P.S:
(a - x)² + (b-y)² = r²
a² - 2ax + x² + b² -2by + y² - r² = 0
x² + y² -2ax - 2by + a² + b² - r² = 0
