The standard deviation<u> </u><u>INCREASES</u>
Step-by-step explanation:
Standard deviation is used to show how the points of the data deviate from the mean. The formulae for deriving standard deviation is attached. As seen from the formulae, the greater the variance of the data from the mean, the higher the Standard Deviation.
The mean of the given data points is $103.4. $450 is way off from this mean meaning that there is a large variance in this data point.
Answer:
x≈ 3.2056
Step-by-step explanation:
Set both sides by log. Then, solve for x.
1. 14^(x + 1) = 36
(x + 1)log(14) = log(36)
x + 1 = log(36)/log(14) . . . Divide both sides by log(14)
x = log(36)/log(14) - 1 . . . . Subtract both sides by 1.
x ≈ 0.3579 . . . . . . . . . . . .Use calculator to simplify the expression.
Note that the second problem is similar to the first.
2. 12^(y - 2) = 20
(y - 2)log(12) = log(20)
y - 2 = log(20)/log(12)
y = log(20)/log(12) + 2
y ≈ 3.2056
Answer:
The answer is 4/9
Step-by-step explanation:
Hi. Here's the work.
First turn everything into an improper fraction.
÷
=
÷ 
To divide fractions we multiply by the flipped version of the fraction, or the reciprocal.
÷
= 
Now we just multiply the fractions!
= 
The answer is therefore 4/9. Please mark brainliest if possible and i hope you get a good grade on your homework. ;)
Answer:
If the line goes through the origin, (0,0), that means the linear equation is proportional, if it doesn't go through the origin, the equation isn't proportional.
You can also tell if a linear equation is proportional if the equation has an constant after the x (for example y=2x+6)
Answer:
2x+7+y=0 -7
2x+y=-7 -2x
y=-2x-7
