Answer:
See below
Step-by-step explanation:
Lets assume weight is input and time is output
The function based on the input and output values is close to linear and it is decreasing (graph is attached)
<u>Answers are</u>
- a) correlation is negative as time decreases with increase in weight.
- b) Numeric value is obtained -0.99 by using the formula attached as picture. It is 'very strong negative relationship'
- c) Yes. Because weigh increase causes time to decrease
The problem is actually already factored for you. They are asking you to just set the equation to zero. Find the zeros.
Answer:
Surface area means all of the outside areas, kind of like when you wrap a present.
Step-by-step explanation:
1st draw the box and find the area of the top and the bottom of the figure
10 x 3 = 30 for the top and 30 for the bottom, so 60 for both.
2nd find the area of two opposite sides:
10x 4.5 = 45 for one side and 45 for the other side, which is 90 for both
3rd find the area of the last two opposite sides:
3 x 4.5 = 13.5 for one side and 13.5 for the other side, so 27 for both.
4th: now add all those sides 60 + 90 + 27 = 177 inches squared.
Answer:
D (0, 5), (5, 0)
Step-by-step explanation:
Anything with -5 and 0 will not satisfy x+y=5. This eliminates the first three choices.
It is easiest to check the offered answers. You can also solve this graphically, or by solving the simultaneous equations.
You can, for example, square the first equation and subtract the second:
... (x+y)² -(x²+y²) = 5² -25
... 2xy = 0
This will be true for x=0 or for y=0, so (0, 5) and (5, 0) are solutions to the pair of equations.
Answer:y=-1/2x
Step-by-step explanation: Because your finding the perpendicular slope, the perpendicular slope is the negative reciprocal of the slope you are given. You are given the slope of 2, and the perpendicular slope is -1/2.
