Answer:

D E B C A ⇒ 2nd answer

Step-by-step explanation:

* Lets revise the steps of bisecting a line segment

1. Place the compass at one end of line segment.

2. Open the compass to slightly longer than half the line

segment length.

3. Draw an arc above and under the line segment

4. Keeping the same compass width, draw an arc above and under

the line segment from other end of line.

5. Each two arcs intersected at a point over the line and another

point under the line.

6. Use the ruler to join these point by a line which is the bisector of

the line segment

* Now lets arrange the steps step

1. Place the compass, and open it wider than half the distance of

the segment ⇒ D

2. Swing an arc above and below the segment ⇒ E

3. Keeping the compass the same width, Place the compass at

point B and swing an arc above and below the segment ⇒ B

4. Place points C and D on the intersection of the arcs created

above and below segment AB ⇒ C

5. Draw a line from point C to point D ⇒ A

∴ The arrange of the statements is ⇒ D E B C A

Simplify (3x2 − 2) (5x2 5x − 1).

Evgen [1.6K]

If you would like to simplify (3x^2 - 2) * (5x^2 + 5x - 1), you can calculate this using the following steps:

(3x^2 - 2) * (5x^2 + 5x - 1) = 3x^2 * 5x^2 + 3x^2 * 5x - 3x^2 * 1 - 2 * 5x^2 - 2 * 5x + 2 * 1 = 15x^4 + 15x^3 - 3x^2 - 10x^2 - 10x + 2 = 15x^4 + 15x^3 - 13x^2 - 10x + 2

The correct result would be 15x^4 + 15x^3 - 13x^2 - 10x + 2.

A variety of stores offer loyalty programs. Participating shoppers swipe a bar-coded tag at the register when checking out and r

Answer:

$t=\frac{130-120}{\frac{40}{\sqrt{80}}}=2.236$

Now we can find the degrees of freedom:

$df=n-1=80-1=79$

Now we can calculate the p value with the alternative hypothesis using the following probability:

$p_v =P(t_{(79)}>2.236)=0.0141$

Using a significance level of 0.01 or 1% we have enough evidence to FAIL to reject the null hypothesis and we can conclude that shoppers participating in the loyalty program NOT spent more on average than typical shopper at this significance level assumed

Step-by-step explanation:

Information given

$\bar X=130$ represent the sample mean

$s=40$ represent the sample standard deviation

$n=80$ sample size

$\mu_o =120$ represent the value to verify

t would represent the statistic

$p_v$ represent the p value

System of hypothesis

We want to verify if shoppers participating in the loyalty program spent more on average than typical shoppers (120) , the system of hypothesis would be:

Null hypothesis: $\mu \leq 120$

Alternative hypothesis: $\mu > 120$

The statistic for this case is given by:

$t=\frac{\bar X-\mu_o}{\frac{s}{\sqrt{n}}}$ (1)

Replacing the info given we got:

$t=\frac{130-120}{\frac{40}{\sqrt{80}}}=2.236$

Now we can find the degrees of freedom:

$df=n-1=80-1=79$

Now we can calculate the p value with the alternative hypothesis using the following probability:

$p_v =P(t_{(79)}>2.236)=0.0141$

Using a significance level of 0.01 or 1% we have enough evidence to FAIL to reject the null hypothesis and we can conclude that shoppers participating in the loyalty program NOT spent more on average than typical shopper at this significance level assumed
