The range of her scores is 17.
<em><u>Explanation</u></em>
Mindy's scores in five tests are: ![95, 86, 78, 80, 91](https://tex.z-dn.net/?f=95%2C%2086%2C%2078%2C%2080%2C%2091)
First, rearranging the data in numerical order, we will get ........
![78, 80, 86, 91, 95](https://tex.z-dn.net/?f=78%2C%2080%2C%2086%2C%2091%2C%2095)
<u>'Range' is the difference between the highest and lowest values</u>.
In the above data set, highest value is 95 and lowest value is 78
So, the range of her scores will be: ![95-78= 17](https://tex.z-dn.net/?f=95-78%3D%2017)
Answer: The answer is A
Step-by-step explanation: I took the test and it was right!
I hope this helped!
16 • (x^2 + 2y^4) • (x^2 - 2y^4)
The number of real solution of the system y =
and y = 3x - 2 is zero
The system of equations are
y = ![3x^2](https://tex.z-dn.net/?f=3x%5E2)
y = 3x - 2
Then the equation will be
= 3x - 2
Move 3x - 2 to the left hand side of the equation
- 3x + 2 = 0
Find the value of
- 4ac
Here value of a = 3
The value of b = -3
The value of c = 2
Substitute the values in the expression
=
- 4×3×2
= 9 - 24
= -15
Here the value of
- 4ac is -15
Therefore there is no real valued solution
Hence, the number of real solution of the system y =
and y = 3x - 2 is zero
