The constant rate of change is 8...any questions?
Answer:
Step-by-step explanation:
y = -x^2+4x-6x +24
y = -x^2 -2x + 24
Vertex (x) = 2/-2 = -1
Vertex (y) = -100/ -4 = 25
Vertex (-1, 25)
axis of symmetry: x= -1
-x^2 -2x + 24 = 0
Δ/4 = 1+24 = 25
x1 = (1 + 5)/-1 = -6
x2 = (1-5)/-1 = 4
left x intercept = (-6,0)
right x intercept = (4,0)
The DOMAIN is the set of all numbers
The range is y less than or equal to 25
Answer:
There is not sufficient evidence to support the claim μ > 54.4.
Step-by-step explanation:
1) Previous concepts
A hypothesis is defined as "a speculation or theory based on insufficient evidence that lends itself to further testing and experimentation. With further testing, a hypothesis can usually be proven true or false".
The null hypothesis is defined as "a hypothesis that says there is no statistical significance between the two variables in the hypothesis. It is the hypothesis that the researcher is trying to disprove".
The alternative hypothesis is "just the inverse, or opposite, of the null hypothesis. It is the hypothesis that researcher is trying to prove".
2) Solution to the problem
On this case we want to test is and the system of hypothesi on this case are:
Null Hypothesis:
Alternative hypothesis:
On this case is our decision is FAILS to reject the null hypothesis then we can conclude that we don't have enough evidence to support the claim at the significance level provided. So the correct conclusion would be:
There is not sufficient evidence to support the claim μ > 54.4.

<h3>
Equation</h3>
An equation is an expression used to show the relationship between two or more numbers and variables.
Let x represent the number of dimes and y represent the number of quarters.
A dime is worth 10 cents. A quarter is worth 25 cents.
Hence:
x + y = 17 (1)
Also:
10x + 25y = 290 (2)
From equation 1 and 2:
x = 9, y = 8
