His score increased by 21%
91-70=21 therefore he increased his score by 21%
Answer:
Her wages would increase by $100 or double to $200 in other words.
Step-by-step explanation:
Her hours doubled so this means that her wages should double as well. Also, she makes $20 an hour so you could also come to this conclusion by multiplying 20 times 10.
By definition, electromagnetic induction is the term that is generally used to describe the method of generating a potential difference across a conductor through a changing magnetic field. In addition, the induce current would be minimised if the loop is placed parallel to the magnetic field itself. Therefore, C.
Answer:
The height of the tree in 2020 was of 19.63 feet.
Step-by-step explanation:
Exponential equation for growth:
The exponential equation for the growth of an amount has the following format:

In which H(t) is the amount after t years, H(0) is the initial amount and r is the growth rate, as a decimal.
A 4 foot tree was planted in 2012 outside a high school.
This means that 
The tree grew continuously by 22% each year from that point.
This means that 
Find out what the height of the tree was in 2020.
2020 is 2020 - 2012 = 8 years after 2012, so this is H(8).




The height of the tree in 2020 was of 19.63 feet.
Answer:
The standard deviation of the price she will get is $8,371.58.
Step-by-step explanation:
An uniform probability is a case of probability in which each outcome is equally as likely.
For this situation, we have a lower limit of the distribution that we call a and an upper limit that we call b.
The variance of the uniform distribution is given by:

The standard deviation is the square root of the variance.
Uniformly distributed between $204,000 and $233,000
This means that 
So

The standard deviation is the square root of the variance. So

The standard deviation of the price she will get is $8,371.58.
