5/8 cant be simplified more. Or you set the problem up wrong.
I am just typing twenty characters the answer is 23
Answer:
21 % increase
Step-by-step explanation:
Lets imagine the sides of the rectangle are 100 & 200 cms.
The area would be 100 x 200 = 20000cm^2
If we added 10% onto each side, the sides would now be 110 & 220 cms.
The area would be 110 x 220 = 24200cm^2
We can now find percentage change:
= 21/100 = 21% increase.
The reason we can just pick random values of sides to do this question with is because we worked out percentage change, which will be the same no matter the proportion of the sides.
Hope this helped! Let me know if you have any questions :)
Answer: d .we are 99% confident that the true mean age of horses with laminitis is between 6.3 and 7.4 years old.
Step-by-step explanation:
- A x% confidence interval interprets that a person can be x% sure that the true population parameter lies in it.
Given : Veterinary researchers at a major university veterinary hospital .
He calculated a 99% confidence interval for the average age of horses admitted for laminitis, a foot disease that leaves the horse severely lame, as 6.3 to 7.4 years.
Here , Population parameter = Mean age of horses with laminitis
Interpretation: We are 99% sure that the true mean age of horses with laminitis is between 6.3 and 7.4 years old.
Hence, the correct option is d .we are 99% confident that the true mean age of horses with laminitis is between 6.3 and 7.4 years old.
Answer:
Step-by-step explanation:
Divide the US population by the world population:
328,200,000/7,674,000,000 = 0.0428
Multiply 0.0428 with 100:
0.0428 x 100 = 4.28
Approximately 4 out of 100 people in the world would live in the USA.
