Actually in this case we will make use of the z test
statistic. In which we calculate for the z score and then use the standard
normal distribution tables to find for the P value at the calculate z score.
z = (x – u) / s
z = (97 – 98) / 2
z = -0.5
The z value should be greater than 1.65 to for the null
hypothesis to be accepted. Hence rejected.
Your answer is the one on the bottom left
Answer: the y intercept is -5
You can use the slope intercept form to find the answer. Aka y = mx + b
In this equation m is equal to the slope and b is equal to the y-intercept.
We already know the slope, 4. And we have two different point we can choose from. I’ll show how to solve with the first (1,-1) point.
Answer:
Step-by-step explanation:
Corresponding angles are congruent
thus, 8x - 17 = 5x +19

Answer:
∑ₙ₌₁⁸ (3n − 9)
Step-by-step explanation:
This is an arithmetic series where the first term is -6 and the common difference is 3. The nth term can be written as:
aₙ = a₁ + d (n − 1)
aₙ = -6 + 3 (n − 1)
There are 8 terms in this series, so the sum is:
∑ₙ₌₁⁸ [-6 + 3 (n − 1)]
Simplified:
∑ₙ₌₁⁸ (3n − 9)
