Answer:
4.24
Step-by-step explanation:
round the hundredths place according to the thousandths place
if the thousandths place (in this case 9) is 5 or greater, round the hundredths place up
if the thousandths place is less than 5, keep the hundredths place the same number
Answer:
Step-by-step explanation:
The question relates to dividing a fraction by proper and another fraction
The given expression is presented as follows;
We rearrange the fractions as improper fractions for easier division as follows;
Therefore, we have;
Answer:
Option B
Step-by-step explanation:
Taking the derivative of the residual function, then applying the normal equation:
[a; b] = (X'*X)^(X'*y)
with
X = [1 1; 2 1; 3 1; 4 1; 5 1]
X' is transpose of X
y = [11; 8; 4; 1; 0]
[a; b] = [-2.9 13.5]
if you look at delta y over x, you'll notice it always equals 2
i.e (22-2)/10-0 = 20/10 = 2
or (14-2)/6-0 = 12/6 = 2
or even (22-8)/10-3 = 14/7 = 2
This means that m (slope) is 2.
Now as for b. b is the y intercept and that value occurs when x = 0. On the table, when x = 0 y = 2 so b = 2.
y = mx + b becomes
y = 2x + 2
For
and
to be inversely proportional, there must be some constant
such that
Given that
when
, it follows that
Then when
, we have
