Hi there!
Which of the following is a true statement? (round to the nearest tenth as needed).
------------------------------------------
Check: u + -10 = 14, when u = -1.4
u(-1.4) + -10 = 14
-11.4 ≠ 14
Answer: False
------------------------------------------
Check: -10 - u = 14, when u = 4.0
-10 - u(4) = 14
-14 ≠ 14
Answer: False
------------------------------------------
Check: -10 + u = 14, when u = 24.0
-10 + u(24) = 14
14 = 14
Answer: True
------------------------------------------
Check: If -10 + u = 14, when u = 4
-10 + u(4) = 14
-6 ≠ 14
Answer: False
------------------------------------------
The statement that is true is: -10 + u = 14, then u = 24.0
------------------------------------------
Hope This Helps :)

La respuesta es yo no se que es la resquesta
Solve for x over the real numbers:
x^2 - 4 x - 5 = 0
The left hand side factors into a product with two terms:
(x - 5) (x + 1) = 0
Split into two equations:
x - 5 = 0 or x + 1 = 0
Add 5 to both sides:
x = 5 or x + 1 = 0
Subtract 1 from both sides:
Answer: x = 5 or x = -1
Answer:
Approximately 68% of students study between 22.9 and 25.7 hours.
Step-by-step explanation:
The Empirical Rule states that, for a normally distributed random variable:
Approximately 68% of the measures are within 1 standard deviation of the mean.
Approximately 95% of the measures are within 2 standard deviations of the mean.
Approximately 99.7% of the measures are within 3 standard deviations of the mean.
In this problem, we have that:
Mean of 24.3 hours, standard deviation of 1.4 hours.
What percent of students study between 22.9 and 25.7 hours?
22.9 = 24.3 - 1.4
25.7 = 24.3 + 1.4
Within 1 standard deviation of the mean, so:
Approximately 68% of students study between 22.9 and 25.7 hours.
