Answer:
p value = 0.302
Step-by-step explanation:
Given that all cars can be classified into one of four groups: the subcompact, the compact, the midsize, and the full-size. There are five cars in each group. Head injury data (in hic) for the dummies in the driver's seat are listed below.
H_0: All cars have same mean values
H_a: atleast two cars have different mean values
(Two tailed anova test)
Anova: Single Factor

Since p value of 0.302 is greater than 0.05 significance level we accept null hypothesis.
p value = 0.302
Step-by-step explanation: Notice that the two equations in this problem have the same slope of -1/4 but different y-intercepts.
When lines have the same slopes, they are parallel.
Parallel lines never meet/intersect so there is no solution.
Answer: Choice B
y = (x+3)^2 - 1
==================================================
Recall that vertex form is y = a(x-h)^2 + k with the vertex being (h,k)
From the given graph, it shows that (h,k) = (-3,1) is the vertex. So we plug this pair of values into the general function above to get
y = a(x-h)^2 + k
y = 1(x-(-3))^2 + (-1)
y = (x+3)^2 - 1
which is the final answer
note: a = 1 is the case for all four answer choices, so we don't have to worry about the value of 'a'
Answer:
Whoes Joe?
Step-by-step explanation:
Answer:
125 times.
Step-by-step explanation:
Prob(Heads) = 1/2.
Prob(Spinner lands on 2) = 1/4 ( as there are 4 sections on the spinner).
So the best prediction for the number of times this occurs in a 1000 trials
= 1/2 * 1/4 * 1000
= 1/8 * 100
= 125 times.
