Answer:
When simplified this equation equals 8.
Step-by-step explanation:
Let me show you my work.
4 ( 3.5 - 1.5 ) = 4 ( 2 )
4 ( 2 ) = 8 because 4 times 2 = 8

1. Mean is the number you get when you add all these numbers and then divide by the number of numbers. So, (31 + 28 + 30 + 31 + 30) / 5 = 150 / 5 = 30
2. The median is the middle number in the list of numbers, so, the answer is 30 as well.
3. Mode is the number that appears most often, so here it is 30 and 31 because they both appear 2 times.
4. Range is the difference between the largest and smallest number, so 31 - 28 = 3.
Answer:

Step-by-step explanation:
First, make them on one side of the formula in the form of
which is 
Next, insert the corresponding number in the quadratic formula,
, and the answer can be calculated.
Answer:
I believe its y=5(4)^x
Step-by-step explanation:
The equation is supposed to look like y=ab^x
a is basically where it all starts, so where the y meets the 0
- so the 5 in the y's place meets the 0
b is what you're multiplying by on the y's side, which is by 4 every time
and the x is the exponent and since there is no exponent you leave it as x
67/100 is approximately 2/3 and 515 is approximately 510 so D. 2/3*510
