Answer:
6
Step-by-step explanation:
The trick here is to know PEMDAS.
PEMDAS stands for: Parentheses, Exponents, Multiplication, Division, Addition, Subtraction.
This is the order in which you should simplify a problem.
Parentheses:
(5 + 1)^2 - (11 + 32) + 4
(6)^2 - (43) + 4
Exponents:
(6)^2 - (43) + 4
36 - 34 + 4
We have no multiplication or division, so we can skip those steps.
Addition:
36 - 34 + 4
40 - 34
Subtraction:
40 - 34
6
So 6 is our answer.
Answer:
Step-by-step explanation:
the simple interest formula= principal* interest rate*time
simple interest : 100000*%2*2 years
simple interest= 4000 dollars
compound quarterly : A=principal(1+r/4)^t
since it is quarterly and have 4 quarters in a year, and 8 in two years.
compound quarterly: 100000(1+0.03/4)^8=106159.88
it is better to invest with compound interest because it add 6159 dollars in two years to the investment of 100000 dollars.
the difference between the interest: 6159.88-4000=2159.88
Using it's concept, it is found that the probability of being a girl and choosing lemonade is given by:
b. 0.2.
<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>.
In this problem, out of 130 people, 26 are girls who choose lemonade, hence the probability is given by:
p = 26/130 = 0.2, which means that option b is correct.
