Answer:
The probability of randomly select an adult that has between 18 and 29 years old and use social media is 22.3%
Step-by-step explanation:
As the test is targeted to 18-to-29-year-old adults using social media, we want to know the probability that a randomly selected adult uses social media and belong to the study group.
To achieve this, we have this data:
- 36% of all adults do not use social media
- 75% of all adults are >30 years old.
- The percentage of population that is <em>either</em> 18-29 years old <em>or</em> uses social media is 66.7%
Using the last data we have that
The probability of randomly select an adult that has between 18 and 29 years old and use social media is 22.3%
3x+y=19
y=19-3x and y=x+3, at a solution both x and y are equal so we can say y=y:
19-3x=x+3
19-4x=3
-4x=-16
x=4, and since y=x+3
y=7 so the solution is the point:
(4,7)
Answer: -7
Step-by-step explanation:
Some of the math terms are originated from the Latin language.
From these terms are "unit" which actually means one of something and also "plus" which means many things added together.
Other terms of Maths are generated from Greek language as "ply" which means many and "nomial" which means term.
