Answer: The equation for the two given points is y=x+b
Step-by-step explanation:
Step 1. First find the slope: 6-7/2-3 = -1/-1=1. The slope is just 1, or x. So for now, the equation is y=x+b
Step 2. We must find the y-intercept, or B. We can plug in any points to find b. Let's use (2, 6) (but you can use (3, 7) too, it doesn't matter) Plug 2 in for x, since 2 represents x, and then do the same for y. ---> 6=2+b.
Step 3. Simplify. 6=2+b. 6-2=2-2+b ---> b=4. Subtract both sides by 2 to get B.
The equation for the two given points is y=x+b
Hope this helps.
Answer:
99.7% data lies between 13 to 43
Step-by-step explanation:
Mean: 
Standard deviation : 
68% of data lies between 
to 
95% of the data lies between 
to 
99.7% data lies between 
to 
We are supposed to find 99.7 of the data will lie between which values
99.7% data lies between 
to 
99.7% data lies between 13 to 43
Hence 99.7% data lies between 13 to 43
Answer:
The function graphed is f(x) = 3x + 1
See that the y=intercept is at (0,1). That's where the +1 comes from.
Note that the graph goes up 3 spaces every time it goes 1 to the right. 3/1 = 3 is the slope.
The answer to 12 is C.
The answer to 13 is B. Neither is a function. For a function of x to exist, for every x, there must be only one y. In both tables, there's a number for x that gives two different y's.

1 Distribute
(8+3)(7+3)
8(7+3)+3(7+3)
2 Distribute
8(7+3)+3(7+3)
562+24+3(7+3)
3 Distribute
562+24+3(7+3)
562+24+21+9
4 Combine like terms
562+24+21+9
562+45+9
Solution

Step-by-step explanation:
The area of a rectangle(A) related to the length (L) and WITDH (W) of its sides by the following Relationship:A=L W if you know the width is easy to find the length rearranging this equation to get L=A÷w if you know the length and want width rearranged to get W=A÷L this is the formula not the answer.
