Answer:
Step-by-step explanation:
Distance between two points:
Suppose that we have two points, 
and 
. The distance between them is given by:
Equation of a circle:
The equation of a circle with center 
and radius r has the following format:
Center at the origin;
This means that 
So
Passes through (4, 6)
The radius is the distance from this point to the center. So
So
Then
Soap because I don’t want to be dirty
Answer:
0.964
Step-by-step explanation:
It's easier to approach this problem if you find the prob. that z is less than -1.8 and then subtract your result from 1.00.
The prob. that z is less than -1.8 can be found using any calculator with probability and statistic functions.
The prob. that z is less than -1.8 = normcdf(-100,-8) = 0.036. Here "cdf" stands for "cumulative probability density function)," -100 is far to the left of z = -1.8, and the result (0.036) is the area under the standard normal probability density curve to the left of z = -1.8.
Finally, subtract this 0.036 from 1.000, obtaining 0.964. This is the probability that z is greater than -1.8.
If she gave all the kids in her class 1 piece of candy, and she had 7 left over, the equation is 97 - 7 = 90. There are 90 kids in her class.
Answer:
<u>226.08 cm³</u>
Step-by-step explanation:
V = 1/3πr³
= 1/3 x 3.14 x 216
= 72 x 3.14
= <u>226.08 cm³</u>
