Answer:
12.1 repeating
Step-by-step explanation:
73/6=12.16666666...
Step-by-step explanation:
Hey there!!
You can simply use midpoint formulae to find midpoint of the coordinates.
Here, Given that;
G(3,3) and H(-7,7).
Using midpoint formulae,
)
)
After simplifying it we get,
= (-2,5).
Therefore, midpoint of GH is M(-2,5).

Answer:
H0: μ = 7.8
Ha: μ > 7.8
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.
For the case above;
Let μ represent the true mean length of long-distance calls after the rate reduction
The null hypothesis is that true mean length of long-distance calls after the rate reduction is the same and equal to 7.8 minutes
H0: μ = 7.8
The alternative hypothesis is that the true mean length of long-distance calls after the rate reduction have increased that is greater than 7.8 minutes
Ha: μ > 7.8
Answer:

Step-by-step explanation:
Given

g(x) = f(x) 4 units left
Required
Find g(x)
When a point is translated 4 units left, the rule is:

So, we have:

is calculated as:

Hence:

Scaled by 2, side lengths are 3, 4 and 5
