Answer:
Step-by-step explanation:
The first question:
91 = 43 + x
x = 91 - 43
x = 48
By using transposing method
Second question:
Answer:
w=3
Step-by-step explanation:
15-5w=0
Add 5w to each side
15 -5w+5w = 5w
15 =5w
Divide each side by 5
15/5 = 5w/5
3 =w
All so have to do is make sure to convert the negatives and positives of the second group of values since there is a subtraction symbol that you have to distribute to that section.
This would turn the expression into
3x^5 + 3x^2 - 4x^3 + x - 6 - x^3 - 4x^4 - 2x^2 + 10x
Then combine like terms and line all the values in order from greatest exponent value to least to get
3x^5 - 4x^4 - 5x^3 + x^2 +11x - 6
Hope this helped :)
Answer:
A. The distribution should be skewed to the left because the mean is less than the median.
B. Most students scored a C or higher.
Step-by-step explanation:
A. Since mean<median<mode, we have a negative skewness and hence the distribution is skewed to the left.
B. Since the mean score is 71 and the modal score is 81, it is expected that a 'C' should be the lowest grade most students will have.
