Answer:
D 565.2 in
Step-by-step explanation:
First you need to find the area of the stepping stone. The rule for area of circle is pi times radius squared. To find the radius you divide 12 by 2 = 6. After you do 6 times 6= 36 you multiply 36 times pi (3.14) = 113.04. After we find the are of the stepping stone we multiply it by five to get how many inches we have to cover. 113.04 times 5= 565.2 in.
Answer:
Number 1 would be figure 2
Number 2 would be figure 1
Number 3 would be figure 3
Step-by-step explanation:
A correlation coefficient describes the relationship between two variables. A zero shows that there is no correlation while a one describes a positive correlation. A negative one describes a negative correlation. Since all of the dot in the scatter plot in figure 2 are spread out and not in a line, it has no correlation or you could say that it's coefficient is zero. Since the dots in figure 1 are going from left to right and are close together, it has a positive correlation. Since the dots in figure three are going right to left and resemble a line, the correlation coefficient is -1.
Answer:
Number of student that will absent = 16000
Step-by-step explanation:
Using direct proportion
8:20 = X:40000
X = (40000 x 8) ÷ 20 = 16000
