Answer:
We will fail to reject the null hypothesis and conclude that there is no sufficient evidence to suggest that more than 10% of the cars from a car manufacture experience engine failures before reaching a mileage of 150,000 miles
Step-by-step explanation:
We are given;
Population proportion; p_o = 10% = 0.1
Sample proportion; p = 9/65 = 0.1385
Z-score formula for this is;
z = (p - p_o)/√(p_o(1 - p_o)/n)
z = (0.1385 - 0.1)/√(0.1(1 - 0.1)/65)
z = 0.0385/0.0372
z = 1.03
From online z-score calculator, we have; p - value = 0.1504
Our p - value is greater than the significance level of 0.1.
Thus,we will fail to reject the null hypothesis and conclude that there is no sufficient evidence to suggest that more than 10% of the cars from a car manufacture experience engine failures before reaching a mileage of 150,000 miles
Answer:There are positive integers, for example, 3, and its opposite, a negative integer, -3.
Step-by-step explanation:
Answer:
Option A f(x) = a(x - 2)^2 + 5
Step-by-step explanation:
Vertex Form : y = a(x-h)^2 + k
In this case, we don't need the a-term because we are only looking for the vertex.
The h-term is how this parabola moved horizontally.
Since the x value is 2, that means that the graph moved 2 spaces towards the right. We plug it in to get:
y = (x - 2)^2
Now we need to find the k value. We see that the vertex is (2,5), and the y-value is 5. That means that the graph moved up to 5 units. Now we plug 5 into the k-value, and this is what we get:
y = (x - 2)^2 + 5
Walah! We're done with the equation, and as we can see, the answer is option A!
To solve this for D you divide both sides by pi and get d=c/pi
