Answer:
If I'm answering this right, the bus should have travel 36 miles in 60 minutes.
If it takes 20 minutes to get to 12 miles then for every twenty minutes you would just add 12 miles.
P = 50
r = 5% or 0.05
t = 1/12
Formula = p(1+rt)
= 50(1+(0.05)(1/12)
= 50(1.0004166667)
= 50.21
For the month, abi has to pay risa $50.21
We have,
1 hour = 60 minutes
Given,
27 miles per hour
= \frac{27~miles}{1 ~hour}
= \frac{27~miles}{60~minutes} because 1 hour = 60 minutes
= \frac{0.45~miles}{1 ~minute}
So, the human ran at a speed of 0.45 miles per minute
Answer:
Correct option: (C) 91.
Step-by-step explanation:
To predict the score received by a student if the number of hours studied is 7 can be done using a regression line.
The general form of a regression line is:

Here,
<em>Y</em> = dependent variable
<em>X</em> = independent variable
<em>α</em> = intercept
<em>β</em> = slope
The formula to compute the slope and intercept are:


Consider the table below.
Compute the value of <em>α</em> as follows:

Compute the value of <em>β</em> as follows:

The regression equation is:

For <em>x</em> = 7 compute the value of <em>y</em> as follows:

Thus, the score received by a student who studied 7 hours is 91.
The correct option is (C).

Answer: f ' (x) = 4x</h3>
=======================================
Work Shown:
f(x) = 2x^2 + 5
f ' (x) = d/dx[ 2x^2 + 5 ]
f ' (x) = d/dx[ 2x^2 ] + d/dx[ 5 ]
f ' (x) = 2*d/dx[ x^2 ] + d/dx[ 5 ]
f ' (x) = 2*2x^1 + 0
f ' (x) = 4x
