Answer:
The amount invested at 4.5% was
The amount invested at 5% was
Step-by-step explanation:
we know that
The simple interest formula is equal to
where
I is the Final Interest Value
P is the Principal amount of money to be invested
r is the rate of interest
t is Number of Time Periods
Let
x -----> the amount invested at 4.5%
9,000-x -----> the amount invested at 5%
in this problem we have
substitute
so
therefore
The amount invested at 4.5% was
The amount invested at 5% was
Answer: 2.5
Step-by-step explanation:
Mean m = Sum s ÷ no of observation n
m = 2.5, n = 10
2.5 = s ÷ 10
s = 10 × 2.5
s = 25.
If one observation 2.5 is deleted from sum 25, new sum equals 25 — 2.5 = 22.5.
The no of observation becomes 9.
Therefore new mean = 22.5 ÷ 9
m = 2.5.

Answer:
nonlinear because the second row isn't going up by the same number
Answer: TRUE
<u>Step-by-step explanation:</u>
an even number is divisible by 2.
Consider even number j which equals 2a and even number k which equals 2b. Then the product of these two numbers (j and k) = 2a*2b = 4ab.
4ab is divisible by 4.
BONUS:
The product of three even numbers is divisible by 2³
The product of four even numbers is divisible by 2⁴
The product of five even numbers is divisible by 2⁵
