Answer:
Step-by-step explanation:
Start with the circumference.
C = 2*pi*r
C = 301.5
pi = 3.14
r = ??
Solution
301.5=3.14 * 2 * r
301.5 = 6.28*r
r = 301.5/6.28
r = 48.01
So the radius = 48.01
The diameter is twice as much or 48.01 * 2 = 96.02
Answer:
2
Step By Step Explanation:
= 2*(8+3*3-4^2)
= 2*(8+3*3-16)
= 2*(8+9-16)
= 2*(17-16)
= 2*(1)
= 2*1
= 2
90°
By definition, lines that connect opposite corners of a kite are perpendicular. The answer must be 90°.
Answer:
The equation of the regression line for the following data is:
y=2.4x+120.1
Step-by-step explanation:
We are given a set of data values in table form as:
Day(x) Number of visitors(y)
1 120
2 124
3 130
4 131
5 135
6 132
7 135
Hence, when we draw a scatter plot with the help of these data points using the linear regression calculator we see that the regression line is a line with y-intercept as (0,120.1) and x-intercept as (-50.04,0)
Hence, the regression line for the following data is:
y=2.4x+120.1
