Using your approximate y-intercept on the line of best fit, your equation would be y=11/7x + 3.
We find the slope by choosing two points that are on the line:
(9, 18) is easy to spot; and (2, 7) is fairly easy to spot as well. The formula for slope is:
m=y₂-y₁/x₂-x₁
m=7-18/2-9 = -11/-7 = 11/7
Slope intercept form, y=mx+b, has the slope and the y-intercept. Plugging those in we have y=11/7x+3.
Answer:
6.91 times 6.91 equals 47.7481
47.7481 times π equals 150.005080183
to the second digit this is
150.01
Answer:
option C
0.531
Step-by-step explanation:
Given in the question,
total number of people of age 35 years = 162
Total number of people of age 35 and having haemoglobin 9 or above
162 - 76
86
probability = 86/162
= 0.531
(32)/8 = 4
The answer is A
