Answer:

The Percent Error for her estimate   = 66.66%

Step-by-step explanation:

The initial estimate time to write a book = 3 hours

The final estimate to write a book = 5 hours

⇒  The Error in the estimation = Final estimate - Initial Estimate

                                                   =  5 hours  - 3 hours  = 2 hours

Now, \textrm{Percentage Error} =  \frac{\textrm{Total error}}{\textrm{Initial Estimate}} \times 100

= \frac{2 }{3}  \times 100  = 66.66

Or, the Percentage in Error  = 66.66%

wariber [46]

Answer:

0.25 (inches?)

Step-by-step explanation:

the equation is:

y=mx+b

y is the length of her hair, the dependent variable, the outcome

m is the slope, which is in this case the growth of her hair in a month

x is the independent variable, or the number of months

b is how long her hair is to start with, which is 12 in

we are looking for m, which is the growth of her hair per month, which is given as 0.25 inches, so that would be the answer

1)When adding two negative numbers, _________ the absolute value of the numbers and keep the negative sign.
butalik [34]


1) add.

for example -1 + -2 = - (||-1| + |-2||), which is -(1+2) or -3


2) subtract

for example 4 + -7 = -(||-7| + |4||), which is - |7 - 4| or -3


3) change
for example 3 - (- 2) = 3 + 2


4) -10

the sum is -10.25, which is closest to -10
