Step-by-step explanation:
4 < 2(x/3)
2 < x/3
x > 6
Hence the arrow towards the right is bigger and we use an empty circle. (B)
Answer:
Amount invested at 8% rate of interest = $11000
Amount invested at 9% rate of interest = $9000
Step-by-step explanation:
Let Amy invested amount in a account with 8% simple interest = $a
Then the interest gained after one year =
=
= 0.08a
Remaining amount for the investment = $(20000 - a)
Interest earned after one year with rate of interest 9%
=
= $(1800 - 0.09a)
Total interest earned after 1 year = $1690
0.08a + (1800 - 0.09a) = 1690
1800 - 0.01a = 1690
0.01a = 110
a = $11000
Amount invested at 8% rate of interest = $11000
Amount invested at 9% rate of interest = $(20000 - 11000) = $9000
Answer:
x^2 -17x+72
Step-by-step explanation:
(x – 8) (x – 9)
FOIL
first x*x =x^2
outer -9*x = -9x
inner -8*x = -8x
last = -9*-8 = 72
Add them together
x^2 -9x-8x+72
x^2 -17x+72
Answer:
(0,1)
Step-by-step explanation:
Using it's concept, the probability that exactly two of the dice show a 1 and exactly two of the dice show a 2 is: 10/243.
<h3>What is a probability?</h3>
A probability is given by the <u>number of desired outcomes divided by the number of total outcomes</u>.
One of the six numbers is of 1, and also one out of six is 2. The other two trials can be any of the other 4 numbers, hence the probability for the six rolls has the following format:
p = (1/6)² x (1/6)² x (4/6)²
This considers just one order, while there are six rolls, hence there are 6! possible orders, hence the probability is:
p = 6! x (1/6)² x (1/6)² x (4/6)² = 120 x 16/46656 = 10/243.
