Y= mx +b ; x is the slope and y is the y-intercept.
So in this case, our equation will be y= 3x + 19 :)
<span>In a normal distribution 68.27% of the values are within one standard deviation from the mean, 95.5% of the values are within two standard deviations from the mean, and 99.7 % of the values are within three standard deviations of the mean
With that you have the answer to the three questions:
</span>
<span>a. significantly high (or at least 2 standard deviations above the mean).
99.5% of the values are within 2 standard deviations from the mean, half of 100% - 95.5% = 4.5% / 2 = 2.25% are above the mean, so the answer is 2.25%
b. significantly low (or at least 2 standard deviations below the mean).
The other half are below 2 standard deviations, so the answer is 2.25%
c. not significant (or less than 2 standard deviations away from the mean).
As said, 95.5% are within the band of two standard deviations from the mean, so the answer is 95.5%.

It would probably be 1 and 3/8 yards of string left because if he cut 5/8 yards of the string it would be a subject of subtraction, so if you would subtract that amount from 2 yards, the answer would be 1 and 3/8 yards of string left, hope this helps, good luck
41 = x/84
x=84*41
x=3444
41 as a fraction of 84 is 3444/84
