Answer:
59°
Step-by-step explanation:
Difference=54-(-5)
=54+5=59
We have been given that the standard deviation of a group of 20 scores is 15 and we are asked to find variance.
Since we know variance is square of standard deviation. In order to find out the variance of the given data we have to take the square of 15.
Therefore, our variance is 225.
425 is decreased to 319.
The above statement means that a number should be deducted from 425 to get the difference of 319.
Let x be the unknown number.
425 - x = 319
425 - 319 = x
106 = x
106 is the unknown number.
It can be phrased like this: 425 decreased by 106 is 319.
Newborn = 18 inches
adult boa = 9 * 18 + 2 = 164 inches
Since all the information is given, then merely put the necessary facts in order.
Had the length of the newborn been unknown, it would have been represented by x.
9x + 2 = 164
9x = 164 - 2
9x = 162
9x/9 = 162/9
x = 18
