Answer: 1. x = (y - 2)² + 8
3. y = 2(x +9)² + 7
<u>Step-by-step explanation:</u>
Notes: Vertex form is: y =a(x - h)² + k or x =a(y - k)² + h
- (h, k) is the vertex
- point of vertex is midpoint of focus and directrix:
- p is the distance from the vertex to the focus
1)
Now let's find the a-value:
Now, plug in a = 1 and (h, k) = (-8, 2) into the equation x =a(y - k)² + h
x = (y - 2)² + 8

2)
Now let's find the a-value:
Now, plug in a = -1/2 and (h, k) = (1, 10) into the equation x =a(y - k)² + h
***************************************************************************************
3)
Now let's find the a-value:
Now, plug in a = 2 and (h, k) = (-9, 7) into the equation y =a(x - h)² + k
y = 2(x +9)² + 7

The answer to your question is 70.08
If it’s division it would be 36 but if in an equation it would be 4. Because 4 x 3 = 12 and 36 divided by three equals 12
Answer:
We cannot determine the appropriate hypotheses to test this study because we are only given the data for the sample size and the population mean. Meanwhile, we need to know the data of the sample mean, the standard deviation and the level of significance before we can state the appropriate hypotheses for this test.
Step-by-step explanation:
Given that:
sample size n = 300
population mean μ = 35
The null hypothesis and the alternative hypothesis can be computed as follows:
Null hypothesis
Alternative hypothesis
The degree of freedom df = n -1
df = 300 - 1
df = 299
