Answer:
No
Step-by-step explanation:
If the center is at (0, 0) and if (0, -9) lies on the circle, then the radius must be 9.
In this case, the equation of this circle is
x^2 + y^2 = r^2 = 9^2.
Does (8, 717) satisfy this equation? No. 717^2 would be far outside of the circle. the distance from the center to the point (8, 17) is not the same as the radius
Standard deviation is simply the square root of the variance.
We need to get the square root of each variance to see whether its standard deviation is greater than its variance.
A. 0.25 ⇒ √0.25 = 0.50
B. 1.75 ⇒ √1.75 = 1.32
C. 2.5 ⇒ √2.5 = 1.58
D. 1.5 ⇒ √1.5 = 1.22
Among the choices, only A. 0.25 has a standard deviation that is greater than the variance. The standard deviation is 0.50
Answer:
The slopes of the line are most likely the same because they are parallel lines. Parallel lines always have the same slope as eachother.
Step-by-step explanation:
Answer: Slope: -1.6
Use the slope formula
substitute point values in the formula
(10 -2)
- like this: m = ----------
(1 - 6)
Simplify each other side of the equation
- simplified: 8/-5
m: - 1.6
The rule of 72 will have you divide 72 over the interest rate in percent form. Ignore the percent symbol
So we'll divide 72 over 8.47 to get...
72/8.47 = 8.50059
which is roughly 8.5 years for the money to double
If we round to the nearest whole number, then it takes 9 years for the money to double (according to the rule of 72). The year 1999 isn't listed so the next best choice is the year 2000. So I'm fairly confident the answer is C) 2000. Though your teacher may have 1998 in mind for some reason. If it were me, I'd go with 2000 because the year 1998 will have the account balance short of the goal of $10,000.
Answer: Choice C) 2000
