Answer:
$ 2263
Step-by-step explanation:
In this case to calculate the standard error of the mean, we only need the standard deviation (sd) and the number of the random sample (n).
sd = 13000
n = 33
SE = sd / (n ^ (1/2))
replacing:
SE = 13000 / (33 ^ (1/2))
SE = 2263.01
What the standard error of the mean for a random sample of 33 first-year lawyers means is $ 2263
Answer:
x = 1 or x = -3/2
Step-by-step explanation:
Solve for x over the real numbers:
2 x^2 + x - 3 = 0
The left hand side factors into a product with two terms:
(x - 1) (2 x + 3) = 0
Split into two equations:
x - 1 = 0 or 2 x + 3 = 0
Add 1 to both sides:
x = 1 or 2 x + 3 = 0
Subtract 3 from both sides:
x = 1 or 2 x = -3
Divide both sides by 2:
Answer: x = 1 or x = -3/2
Answer:
i believe its a square :)
Step-by-step explanation:
Given that the tornado traveled 260 miles in 4 hours, its initial speed is 65 mi/h. Then, slowing by 20% every hour, the speed after 2 hours can be calculated through the equation,
speed = (65 mi/h) x (1-0.2)^2
speed = 41.6 mi/h
Thus, the speed of the tornado after 2 hours is approximately 41.6 mi/h.

18b - 3c -10
