Answer:
<h2>31.25% or 1/16 of her test</h2>
Step-by-step explanation:
Step one:
given
let the total amount of her test be x
we are told that she complete 1/8x test in 2/5 of an hour
hence she completed 1/8x in 0.4 hours
let us find the rate at which she completes are test
rate= 1/8x/0.4
convert the numerator to decimal number for easy computation
rate= 0.125x/0.4
rate=0.3125x per hour
Step two:
Hence 1 hour she can finish 0.3125x *1
=0.3125x
She can finish 31.25 % of her test in 1 hour
or 1/16 of her test
Answer:
10
Step-by-step explanation:
You must use distributive property to get 2m+10+48m+8 and then add all like terms. You get 50m+18 as your final answer.
<u>Answer-</u>
<em>The </em><em>exponential model</em><em> best fits the data set.</em>
<u>Solution-</u>
x = input variable = number of practice throws
y = output variable = number of free throws
Using Excel, Linear, Quadratic and Exponential regression model were generated.
The best fit equation and co-efficient of determination R² are as follows,
<u>Linear Regression</u>

<u>Quadratic Regression</u>

<u>Exponential Regression</u>

The value of co-efficient of determination R² ranges from 0 to 1, the more closer its value to 1 the better the regression model is.
Now,

Therefore, the Exponential Regression model must be followed.
