You would do 300• 31/100 to get 90. I’m pretty sure that’s right
Answer:
solutions
Step-by-step explanation:
Another term for the roots or x-intercepts of the standard-form quadratic equation is "<em>solutions</em>." These are the values of x that make the equation true.
a = 4, b= 9. Explanation: Since all of it is to the power of 3, we can divide the exponents to of the results (right side of the equation). 12/3=4, 27/3=9. Hope this helps.
5x+2y=20 when x=3/10 is:
5(3/10)+2y=20
15/10+2y=20
1.5+2y=20
2y=18.5
y=9.25
Options:
A. 18, 20, 20, 22, 25
B. 20, 20, 20, 25, 25
C. 16, 19, 21, 22, 22
D. 20, 20, 21, 22, 22
Answer:
A. 18, 20, 20, 22, 25
Step-by-step explanation:
Required
Which list has a mean of 21 and median of 20
Each of the list have 5 numbers and they've all been sorted.
The median is the number at the 3rd position (i.e. the middle number)
So, list C and D are out because they do not have a median of 20.
Next, calculate the mean of lists A and B

A. 18, 20, 20, 22, 25



B. 20, 20, 20, 25, 25



Only list A has a median value of 20 and a mean value of 21
