3/5 is 60% 3/15 is 20% divide 60% by 20% and you have a 3 hope this helps
Because all are a multiple of 2, you can factor out 2, 2(-x^2+x+2)=0
Answer:
Option 3 is correct that is prime numbers.
Step-by-step explanation:
Even numbers are those which are divisible by 2
Prime numbers are the numbers which are divisible by 1 and the number itself
Since, we have to take only positive numbers
Carrie has taken out the set of even number within the set of prime number
So, 2 is the only number inside this eset because 2 is even as well as prime
Hence,universal set will be prime numbers
Therefore, Option 3 is correct that is prime numbers.
Answer:
x = 1/5 , and x = - 1/5
Step-by-step explanation:
25x² – 1 = 0
5²x² - 1² = 0
(5x - 1)(5x + 1) = 0
5x -1 = 0, 5x + 1 = 0
x = 1/5 , x = - 1/5
Given :
On average, a refrigerator door is opened 99 times each day.
Len has two refrigerators in his house.
To Find :
How many times in a 8−week period are the refrigerator doors opened.
Solution :
Number of times door opened for 2 refrigerator , n = 99×2 = 198.
Number of days in 8 week , d = 8×7 = 56 days.
So, total number of times doors open in a period of 8-week is :

Therefore, refrigerator doors are opened about 11088 times.
Hence, this is the required solution.
