I think it’s b cos u minus 43 and your left with 48x and 47x so divide by 47 and you get 1 point something x = to x so yeah probably none because no number will make that work so it’s b

If a 1% level of significance is used to test a null hypothesis, there is a probability of __________ of rejecting the null hypo

USPshnik [31]

Answer:

If a 1% level of significance is used to test a null hypothesis, there is a probability of ____ less than 1%______ of rejecting the null hypothesis when it is true

Step-by-step explanation:

Given that a hypothesis testing is done.

Level of significance used is 1%

i.e. alpha = 1%

When we do hypothesis test, we find out test statistic Z or t suitable for the test and find p value

If p value is < 1% we reject null hypothesis otherwise we accept null hypothesis.

So p value can be atmost 1% only for accepting null hypothesis.

So the answer is 1%

If a 1% level of significance is used to test a null hypothesis, there is a probability of ____less than 1%______ of rejecting the null hypothesis when it is true.

Help me with this parallelogram please :)

antoniya [11.8K]

Parallel sides of parallelogram are equal in length

$\\ \sf\longmapsto AD=BC$

$\\ \sf\longmapsto 6x+14=9x-4$

$\\ \sf\longmapsto 9x-6x=14+4$

$\\ \sf\longmapsto 3x=18$

$\\ \sf\longmapsto x=6$

AD=6x+14=6(6)+14=36+14=50

Graph the inequality x>-8 using the steps

Yuki888 [10]

Hey!

Your point on the graph would be ( -8, 0 ).

We shade the right side of the graph because the inequality shows that x is greater than -8.

Hope this helps!
