The mean because the data is symmetrical and there are no outliers
D = RT
D = (65)(5)
D = 325
You do this via. substitution.
Answer:
4(a-1)(a-2)
Step-by-step explanation:
take out 4 (common factor)
4(a^2-3a+2)
then use box method to factor
<u> a -1</u>
a<u> a^2 -a</u>
<u>-</u>2<u> -2a 2</u>
4(a-1)(a-2)
Answer:
a) see graph
b) No
Step-by-step explanation:
The given relation is
{
}
The arrow diagram is shown in the attachment.
b) The relation is not a function because -2 alone maps onto two different y-values.
One-to-many relation cannot be a function.
Let me show u one in detail.
First we have to find the common ratio. We do this by dividing the second term by the first term.
ur first problem...
12/3 = 4...so the common ratio is 4
now we use the formula
an = a1 * r^(n-1)
n = term u want to find = 15
a1 = first term = 3
r = common ratio = 4
now we sub
a15 = 3 * 4^(15 - 1)
a15 = 3 * 4^14
a15 = 3 * 268435456
a15 = 805,306,368 <== ur 15th term
thats all there is to it...and, of course, u can always look on the internet for a geometric sequence calculator...to check urself...lol
