All insurance companies are equal. Each one is as good as any other one. true or false?

2 answers:

5 0

I would say false just because if someone thinks one is better than another it is an opinion. I think false because saying something is equally popular to another is an opinion but if the companies were saying they were alike it would be a fact.

Please let me know if this helped you at all.

It is false because a insurance company can’t be the same one is always better than the other and one does something better than the other

Using either the critical value rule or the p-value rule, if a one-sided null hypothesis for a single mean cannot be rejected at

KiRa [710]

Answer:

Step-by-step explanation:

Using either the critical value rule or the p-value rule, a conclusion can be drawn at a level of significance (alpha)

The null hypothesis: u = hypothesized mean

Alternative hypothesis: u > u0 or u < u0 for a one tailed test

Alternative hypothesis for a two tailed test: u =/ u0

To draw a conclusion by failing to reject the null hypothesis as stated then: using critical value

Observed z score > critical z score for both the one and two tailed test.

Or using p value:

P-value > alpha for a one tailed test

P-value > alpha/2 for a two tailed test

Thus, if a one-sided null hypothesis for a single mean cannot be rejected at a given significance level, then the corresponding two-sided null hypothesis will also not be rejected at the same significance level.

3. A rabbit and turtle are in a race. Is the relationship between distance

frutty [35]

Answer:

The relationship is proportional for the turtle and the equation is Distance = 54*Time

Step-by-step explanation:

Turtle’s run:

Distance (meters) | Time (minutes)

108 | 2

405 | 7.5

540 | 10

1768.5 | 32.75

Rabbitt’s run:

Distance (meters) | Time (minutes)

800 | 1

900 | 5

1107.5 | 20

1524 | 32.5

The relationship between distance traveled and time is proportional if this equation is satisfied:

Distance = k*Time or k = Distance/Time

where k is a constant

For the turtle:

108/2 = 405/7.5 = 540/10 = 1768.5/32.75 = 54

Then, the relationship is proportional and the equation is Distance = 54*Time

For the rabbit:

800/ 1 = 800

900/5 = 180

1107.5/20 = 55.375

1524/32.5 = 46.89

Then, the relationship is not proportional.

What is the recursive formula for this geometric sequence?–2, –16, –128, –1024, ...

Tatiana [17]

Answer:

$b_n=-2\cdot 8^{n-1}$

Step-by-step explanation:

Denote first four terms of the geometrc sequence as

$b_1=-2,\\ \\b_2=-16,\\ \\b_3=-128,\\ \\b_4=-1024.$

Note that

$b_2=b_1\cdot q\Rightarrow -16=-2\cdot 8;\\ \\b_3=b_2\cdot q\Rightarrow -128=-16\cdot 8;\\ \\b_4=b_3\cdot q\Rightarrow -1024=-128\cdot 8.$

Then the common ratio is

$q=8.$

Therefore, the recursive formula for the geometric sequence is

$b_n=b_1\cdot q^{n-1}\Roghtarrow b_n=-2\cdot 8^{n-1}.$

Answer:

2. angle BAD is equal to angle DCB?

3. angle CBA is equal to angle ADC, then

4.triangle BEA is equal to triangle DEC and triangle BEC is equal to DEA

Step-by-step explanation:

since line BCD is equal to line DAB

AND line CBA is equal to line ADC

and because BEA triangle equals DEC, angles BEA and DEC are congruent

and angle BEC is equal to DEA

and yeah your right, it would be supplementary.
