Which combined inequality has the same solution set shown in the graph of x?

alexandr402 [8]

Step-by-step explanation:

an open (empty) point means the point itself is not included.

a closed (filled) point means the point itself is included.

the x values going from -3 (not included) to -1 (included) means

-3 < x <= -1

so, the second answer is correct.

Suppose you deposit $600 into an account that pays 5% annual interest, compounded continuously. How much will you have in the ac

Sever21 [200]

Answer:

D)$732.84

Step-by-step explanation:

A=p(1+r/n)^nt

P=principal=$600

r=5%=0.05

t=4 years

n=12 months

A=p(1+r/n)^nt

=600(1+0.05/12)^12*4

=600(1+0.0041666666666 )^48

=600(1.0041666666666 )^48

=600( 1.2208953550215 )

=732.53

A=$732.53

Option D)$732.84 is the answer

The graph of F(x), shown below, has the same shape as the graph of G(x) = x2, but it is shifted to the left 1 unit. What is its

Brut [27]

Your answer is D. There is a simple way of describing this. In the equation above, you can see ' $x^{2}$ '. This means that if the shape was shifted one unit left, it becomes -1 on the x-axis. The +1 value marks the distance from zero.

5. Find the slope that intersects the x-axis at (1,3) and the y-axis at (4,7).

kotykmax [81]

For this case we have that by definition, the slope of a line is given by:

$m = \frac {y_ {2} -y_ {1}} {x_ {2} -x_ {1}}$

Where:

$(x_ {1}, y_ {1})\\(x_ {2}, y_ {2})$

They are two points through which the line passes.

According to the statement we have two points:

$(x_ {1}, y_ {1}) :( 1,3)\\(x_ {2}, y_ {2}) :( 4,7)$

Substituting we have:

$m = \frac {7-3} {4-1} = \frac {4} {3}$

Thus, the slope of the line is:

$\frac {4} {3}$

Answer:

$\frac {4} {3}$

For hypotheses correct option is (a).

The test statistics is

Degree of freedom: df=n-2= 22

The p-value is: 0.000

The critical value of t is to/2 = 2.07

Since p-value is less than 0.05 so we reject the null hypothesis. There is significant evidence ....
