Step-by-step explanation:
Given:
The radius of a circular sign is 12 inches.
Equal parts of the sign are painted red and yellow.
Question asked:
How many square inches are painted each color?
Solution:
Here given that <u> a circular sign is divided into two equal parts </u>and one part is painted with red and other with yellow and we have to calculate the area of each color:
We will find area of semicircle of each color:
Thus, 226.285 square inches are painted each color.
The answer is (-2, -1) hope this helps!
Answer:
a) 20%
b) 40%
c) Mean = 62.5 seconds; Variance = 52.083 seconds
Step-by-step explanation:
The time it takes a hematology cell counter to complete a test on a blood sample is continuously distributed over the period of 50 to 75 seconds with probability f(x) = 0.04.
a) The percentage of tests require more than 70 seconds is:
b)The percentage of tests that require less than one minute (60 seconds) is:
c) The mean and variance of a continuous distribution are determined by:
Mean = 62.5 seconds.
Variance = 52.083 seconds.
2 4/5 , 2.6 , 2.3 would be your answers in descending order. From greatest to least.
