Answer:
D
Step-by-step explanation: We know it's not A or B because a statistical question is a question that will vary. D has that exact response while C is not exactly what a statistical question is.
Answer:
$1280.59
53 years
Step-by-step explanation:
To find how much we will get in 5 years, we use the formula:

P = $1200
r = 1.3% or 0.013
t = 5
Now that we have our values, let's plug them into the formula.



We will have $1280.59 after 5 years.
Now to find how long it will take for our investment to double.
t = ln(A/P)/r
A = 2400
P = 1200
r = 1.3 or 0.013
Let's plug it in.
t = ln(2400/1200)/0.013
t = ln(2)/0.013
t = 53.32 or 53 years
Answer:

Step-by-step explanation:
The formula to calculate the average acceleration is:

Where <em>s</em> is the speed of the object and <em>t </em>is the time it takes the object to change its speed
to the speed 
In this case we have that:





Answer:
The answer is A: 6√2 - 2√30 + 6 - 2√15
Believe me it right.
x = 8-(-2.25) = 8+2.25 = 10.25
y = 6-4.2-(-4.9)=6-4.2+4.9=6+0.7=6.7
<span>x-y = 10.25.-6.7=
