Answer:

[tex]y = 2 {(x - 3)}^{2} + 1[/tex]

Answer:

D) 2(x - 3)² + 1

Step-by-step explanation:

First off:

the equations are in y = a(x-h)²+k format.

So, that means that since the vtx is (3, 1), the answers could only be c or d

The difference between the two is one parabola is reflected (negative) and the other is facing up. Since (1, 9) is above the vtx, only D is the one that passes through (1, 9) because it is the only one facing upward to touch that point.

Answer:

1. y - 2 = (3/5) (x + 5)

2. y = -5x - 4

Step-by-step explanation:

Slope form - y1 - y = m (x1 - x)

Slope intercept - y = mx + b

______________________________

 - We combine the [tex](x)[/tex] variables because to get to the end sum of the equation, there can only be 1 variable. So to get the 1, you combine like terms.

 - We do this to get 1 number left over. To do this you do the opposite of what you see. In this case we have a negative 19, so you add 19 on each side of the equals.

 - We do this to get x alone. To do this you do the opposite of what you see. In this case we have [tex]4(x)[/tex] which is multiplying, so you divide by 4 on each side.

So your answer is [tex]\bold{x=9}[/tex].

Answer:

H0 : μ2004 - μ2000 = 0

Step-by-step explanation:

Given the data:

Year ________: 2000 ___ 2004

Mean ________ 27.34 ___ 48.12

Std. Dev _______10.11 ____ 19.23

Unweighted n 43 54

The hypothesis is to test if there was a significant difference in the average number of hours worked in a week from 2000 to 2004 ;

Hence, the null hypothesis will negate the hypothesis, that is there is no difference in the average hours worked in a week from 2000 to 2004

Null hypothesis ; H0 : μ2 - μ1 = 0

Alternative hypothesis ; H1 : μ2 - μ1 ≠ 0

Null hypothesis suggest that there is no significant relationship exist in the given set of single observed variable.. As the null hypothesis negate the hypothesis. Hence the difference is zero and hypothesis for the given problem is,

[tex]H_0; (\mu_1-\mu_2)=0[/tex]

[tex]H_a; (\mu_1-\mu_2)\neq 0[/tex]

For year                     2000         2004

Mean                          27.34          48.12

Standard Deviation   10.11          19.23

Unweighted n             43              54

Null hypothesis suggest that there is no significant relationship exist in the given set of single observed variable.

Now the Analyst want to know if there was a significant difference in the average of hours worked in a week from year 2000 to 2004.

To detect a difference (if there it is) between the average of hours worked in a week from 2000 to 2000, it should be test the null hypothesis that there is no difference between the means against the alternative hypothesis. Therefore,

[tex]H_0; (\mu_1-\mu_2)=D_0=0[/tex]

Versus

[tex]H_a; (\mu_1-\mu_2)\neq 0[/tex]

As the null hypothesis negate the hypothesis. Hence the difference is zero and hypothesis for the given problem is,

[tex]H_0; (\mu_1-\mu_2)=0[/tex]

[tex]H_a; (\mu_1-\mu_2)\neq 0[/tex]

(hope this helps can i plz have brainlist :D hehe)

Step-by-step explanation:

1. Not a function There is no correlation plus there is two y values for the same x.

2.Not a function, There is two y values for the same x

3.Yes, you can draw a linear line through the points to represent the equation, also there is one x for one y.

4.Yes, this is a step function. It seems there are two y values for same x. but the shaded circle means to include it and the open circle means dont include it so it is a function.

5.No, this is a parabola but this function has two y values for the same x

6. Yes, this is a absolute value function and there is multiple x values for the same y so it IS a function

Graph 3,6,4 represents a function because the x’s do not repeat and it passes the vertical line test. Which means 1,2,5 is not a function because the x's do repeat and it does not pass the vertical line test
