Answer:
x = -9
Step-by-step explanation:
5x + 4 = -41 Your goal is to get x alone on on side
- 4 - 4 Subtract 4 from both sides to get 5x alone
5x = -45 Now you need to divide to get what x equals
Divide by 5 to get x
To find the common ratio, divide the second term by the first term
-10 / 2 = -5
to find each term in a geometric sequence, u multiply by the common ratio.....
2 * -5 = -10
-10 * -5 = 50
50 * -5 = - 250 <== ur next term

i need more info
Step-by-step explanation:
please comment on this to tell me all of said details
It is x>/0.2 so easy, just divide both sides by 0.3
To compare the two classes, the Coefficient of Variation (COV) can be used.
The formula for COV is this:
C = s / x
where s is the standard deviation and x is the mean
For the first class:
C1 = 10.2 / 75.5
C1 = 0.1351 (13.51%)
For the second class:
C2 = 22.5 / 75.5
C2 = 0.2980 (29.80%)
The COV is a test of homogeneity. Looking at the values, the first class has more students having a grade closer to the average than the second class.
