Given:
The variance of a distribution = 195.
To find:
The standard deviation, rounded to the nearest thousandth.
Solution:
Standard deviation of a distribution is the square root of the variance of the distribution.
Here, the standard deviation of the distribution is
Therefore, the standard deviation is 13.964.
Answer: 1) B is correct, constant of variation is -2.
Step-by-step explanation:
1)
Direct variation states that a relationship between the two variables. we say y varies directly as x
i.e, or y =kx.................[1] ; where k is the constant of variation.
Given the equation:
Divide both sides by -4 we get;
Simplify:
.......[2]
On comparing equation [2] with [1] we get;
k = -2
Answer:
A unit rate is a rate with 1 in the denominator.
Step-by-step explanation:
If you would like to know the number of minutes of long-distance calls you made, you can calculate this using the following steps:
3.3 cents = $0.033
m = $3.40 / 3.3 cents
m = $3.40 / $0.033 = 3.40 / 0.033
m = 103.03 minutes
The correct result would be <span>103.03 minutes.</span>
Answer:
C. 3
Step-by-step explanation:
5x - 2 = 13
5x = 15
x = 15 ÷ 3
x = 3
