Answer:
The probability the average mpg is less than 28 mpg is 0.8413.
Step-by-step explanation:
Given : The manufacturer of a new compact car claims the miles per gallon (mpg) for the gasoline consumption is approximately normal with
Mean mpg and standard deviation mpg.
Number of sample n=36
To find : What is the probability the average mpg is less than 28 mpg?
Solution :
Applying z-score formula,
The portability is given by,
Using z-table,
Therefore, the probability the average mpg is less than 28 mpg is 0.8413.
Answer:
Sum. If the problem asks to add the two fractions, the result is:
Step-by-step explanation:
If you mean to simply state whether this is a sum or a difference, it's a sum.
This is because of the + sign present between the two fractions which indicates it's an addition.
If it was a - it would indicate it was a subtraction problem (or difference)
In order to solve this, we will have to get a common denominator on both fractions. In this case, to do this, we can multiply each denominator to the other fraction, such that:
This can't be simplified further, but can be represented in decimal form as 1.20833.
Good luck!
Answer:
The final equation is .
Step-by-step explanation:
To rewrite an equation in slope-intercept form, our equation must be in form. This means the <em>y</em>-variable must be on the left side of the equation and the slope and y-intercept must be on the right side of the equation. We can do this by moving the equation around.
And then, we're done! Our final answer is .
Answer:
(2x⁶ + 5y³)(2x⁶-5y³)
Step-by-step explanation:
I hope its correct..Cause Even I am not so good at maths..I tried
We need volume
Find volume of big cuboid then subtract the small one
For big one
Volume
- LBH
- 25(24)(8)
- 24(200)
- 4800ft³
For small one
Volume
- LBH
- 25(20)(3)
- 500(3)
- 1500ft³
TOTAL volume
