Sq.root of 1240 is approx 35 mm
<u>Answer:</u>
The point-slope equation of the line is or
<u>Solution:
</u>
Let us assume that the slope is m and the y intercept of the line is b
Hence, --------- (i)
y intercept means we need to find the value of y when x is 0
Here the line passes through point (4,-6) and slope m = (-2)
Now putting the point (4,-6) in equation (i) we get,
So, the equation of the line will be will be or
Answer: The temperature that separates the top 7% with the bottom 93% is 99.12 degrees.
The z-score that corresponds to 93% is about 1.48. If we write the equation for the z-score, we can solve for the missing temperature.
The equation would be:
(x - 98.2) / 0.62 = 1.48
x - 98.2 = 0.9176
x = 99.12 degrees
