Really any option.
Explanation: A triangle can be obtuse of acute, either of these answers will make one of those.
Answer:
Step-by-step explanation:
Yes. The commutative property of addition (as well as the commutative property of multiplication) applies to all real numbers, and even to complex numbers. As an example (for integers):
5 + (-3) = (-3) + 5
A 90º degree angle is a right angle. Anything below is an acute angle and anything more than 90º is an obtuse angle.
Answer:
a=-32 if you think that was a good answer pls mark as brainliest
Step-by-step explanation:
a-(-14) is the same as a+14
a+14=-18
a=-32
Answer:
99.7% of the distribution will be between 600 hours and 900 hours.
Step-by-step explanation:
The Empirical Rule states that, for a normally distributed random variable:
68% of the measures are within 1 standard deviation of the mean.
95% of the measures are within 2 standard deviation of the mean.
99.7% of the measures are within 3 standard deviations of the mean.
In this problem, we have that:
Mean = 750
Standard deviation = 50
What percent of the distribution will be between 600 hours and 900 hours?
600 = 750 - 3*50
600 is 3 standard deviations below the mean
900 = 750 + 3*50
900 is 3 standard deviations above the mean
By the Empirical Rule, 99.7% of the distribution will be between 600 hours and 900 hours.
