Answer:
b. All real numbers
Step-by-step explanation:
Simplify:
- 5(x-2) = (15x+6)/(3) - 12
- 5x - 10 = 5x + 2 - 12
- 5x - 10 = 5x - 10
- -10 = -10
- 0 = 0
Since both sides are equal to each other, any value of x makes this equation true.
Answer:
0.9812
Step-by-step explanation:
Given that human weights are normally distributed with mean 175 and standard deviation 36 pounds
For a sample of 9 people std error of sample would be

Thus we find that sample mean is N(175, 12)
The plane will lift safely if sample average <200 pounds
i.e. Probability that it can safely lift off (i.e., the average weight of a person in the helicopter is less than 200)
= 
~0.981
Answer:
x=−2.181818
Step-by-step explanation:
Answer:
55.27 miles
Step-by-step explanation:
Hello, I think I can help you with this
you can easily solve this by using a simple rule of three
Step one
If 1 mile is approximately 1.61 kilometers,it is
1 miles ⇔ 1.61 Kilometers
the, how many miles(x) are 89 km?
x ⇔ 89 kilometers
the relation is

Step two
solve for x( isolating x)

55.27 miles
Have a good day
