Answer:
Step-by-step explanation:
F:7x•x= 7x^2
O:7x•3=21x
I:3•x=3x
L:3•3=9
Answer: 7x^2+24x+9
For a normally distributed data set, approximately 68.27% of the data is within one standard deviation. i.e. approximately 0.6827 x 200 = 137 test scores is between 86 + or - 3 i.e. from 83 to 89. Hence approximately 137/2 = 68 test score is within the 86 to 89 range.
This is what I got for the question you wanted the answer for...
Hope this helps you ☁︎☀︎☁︎♥︎
The base would be 1/3
since 1/3 x 1/3 is 1/9
-|-10|-(-10)
A negative outside of the “ | “ means that one number inside will be negative . -10-(-10)
An imaginary | will “appear” in between the two negative signs or it will turn into an addition sign.
-10+10
A positive subtracts negatives from the negative number. The answer is 0
I hope this helped.
