Number of Products which are prime numbers = 8
ii) Not a perfect square
Number of products which are perfect squares =11
iii) A multiple of 5
Number of Products that are multiples of 5=15
iv) Less than or equal to 21
Number of products less than or equal to 21=40
v) Divisible by 4 or 6
Products Divisible by 4 or 6= 42
Answer:
The balance of the savings account after all the interest is paid for the year is $3,844.30
Step-by-step explanation:
In the question we have been given the Annual percentage yield as 3.9% , the principal as 3,700 and the time to be 1 year and asked to determine the accumulated amount in the savings account at the end of the year.
The accumulated amount can be determined using the compound interest formula;
Therefore, the balance of the savings account after all the interest is paid for the year is $3,844.30
1. 20, there is 4 1/2s so that is 2 and there is 18 whole squares.
2. 10x8 =80
80/2=40. answer is 40
The line x=4 is a straight vertical line. If we were to measure it's slope using rise over run, we will get 0 in the denominator because there is no change in the x direction. Therefore, the slope of the line is undefined.
Answer:
a third 1/3
Step-by-step explanation
first write the equation
express 8 to power form = 2^3x don't forget the unknown , which is x
it becomes ; 2^3x = 2^1
since the base numbers are same, cancel them.
equate the powers ; 3x=1
divide both sides by the number next to the unknown to get the answer.
