-9(z + 3) - 5(2z + 10)
Distribute -9:
-9z - 27 - 5(2z + 10)
Distribute -5:
-9z - 27 - 10z - 50
Combine like terms:
-19z - 77
Answer: H0 : u = 6 ounces
Ha : u not equal to 6 ounces
Step-by-step explanation:
The null hypothesis (H0) tries to show that no significant variation exists between variables or that a single variable is no different than its mean.
While an alternative Hypothesis (Ha) attempt to prove that a new theory is true rather than the old one. That a variable is significantly different from the mean.
Therefore, for the case above;
H0 : u = 6
Ha : u not equal to 6.
Answer:
128 days and 4000 days
Step-by-step explanation:
Answer: 2 times sqrt(181) (approximately 26.9)
Step-by-step explanation:
First, we can plot these points on a graph. Then, we’ll use the Distance Formula to calculate the distance between the two points, which is sqrt(181).
Since the problem tells us that one of our coordinates is the midpoint of K, we know that the length of the segment we just calculated is 1/2 of K. We can multiply our answer to get that K is 2 times sqrt(181).
