Answer:
2ft
Step-by-step explanation:
The tide doesn't effect the part of ladder that is underwater that is always 2ft
4 feet, divide the # of inches by twelve and it equals the feet.
Answer:
The first one is the answer.
Step-by-step explanation:
It's an arithmetic sequence. It has a common difference.
d = an - a_n-1
an = -12x + 12
a_n-1 = - 7x + 8
d = -12x + 12 - (-7x + 8)
d = -12x + 12 + 7x - 8
d = -5x + 4
Try it. Let's try for the third term
-12x + 12 - 5x + 4
- 17x + 15 which is exactly what the third term is.
For a data point measured as y = 3.5 for an x value of x = 1.2, the residual would be 0.1
For given question,
we have been given an equation 2x + 1 that represents an equation for a trendline to the data.
General formula with residual is y = 2x + 1 + r, where r is a residual.
We need to find the residual for a data point measured as y = 3.5 for an x value of x = 1.2
We substitute given values of x and y in the residual equation
y = 2x + 1 + r
For y = 3.5 and x = 1.2,
⇒ 3.5 = 2(1.2) + 1 + r
⇒ 3.5 = 2.4 + 1 + r
⇒ r = 3.5 - 3.4
⇒ r = 0.1
Therefore, for a data point measured as y = 3.5 for an x value of x = 1.2, the residual would be 0.1

$42.
50% of 84 is the same as 84/2, which is 42.
