Answer:
C. x=12
Step-by-step explanation:
Since, the variance calculated on 34 scores is equal to 14.94.
We have to determine the standard deviation.
Relationship between Variance and standard deviation is:
Standard deviation = 
Substituting the value of Variance, to evaluate the standard deviation.
We get,
Standard deviation = 
= 3.865
= 3.87
Therefore, the standard deviation is 3.87
Answer:
2.40x=40 if that's an option!
Step-by-step explanation:
Answer:
slope = 8, y- intercept = 5
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + b ( m is the slope and b the y- intercept )
Given
- 8x + y = 5 ( add 8x to both sides )
y = 8x + 5 ← in slope- intercept form
with slope m = 8 and y- intercept c = 5
Answer:
3:5, 12:20
Step-by-step explanation:
A ratio is basically just a fraction. Therefore, 6:10 is just 6/10, or 3/5, or 3:5. It's the same thing as a fraction, just with a colon.
Thus, all you need is two equivalent fractions to 6/10. Examples are 3/5, 12/20, 30/50, etc. After you find the fractions, you just need to put them back into ratio form, so 3:5, 12:20, 30:50, etc.
