Considering that the p-value associated for a r<em>ight-tailed test with z = 2.115</em> is of 0.0172, it is found that it is significant at the 5% level, but not at the 1% level.

<h3>When a measure is significant?</h3>

If p-value > significance level, the measure is not significant.

If p-value < significance level, the measure is significant.

Using a z-distribution calculator, it is found that the p-value associated for a r<em>ight-tailed test with z = 2.115</em> is of 0.0172, hence, this is significant at the 5% level, but not at the 1% level.

Clarissa has a bag of marbles. 9 are blue, 5 dre yellow, 2 dre purple, and 4 are green. What is the probability Clarissa reaches

brilliants [131]

Answer:

Step-by-step explanation:

So, first lets the probability of just finding a yellow marble. There are 9+5+2+4 marbles in total, and that is 19 marbles.

5 out of those 20 are yellow, so the probabilty is 5/20 which is 1/4 or 20%

Then, lets do just finding the probability of a color that isn't blue.

Out of 20 marbles, 11 are color not blue, and 9 are.

So that probability is 11/20

Now, I think we need to do 11/20-5/20 so 6/20=3/10

Im so sorry, I might be wrong. I found both probabilities but I dont know if my final step is right.

Answer:

A proportional relationship is there.

Step-by-step explanation:

Here in the table, the values of y are given corresponding to the values of x.

There are four sets of values of x and y.

We have to check whether the relationship is proportional or not.

Now, rate of change of y with respect to x will be from the first two pair of values is = $\frac{3.5 - (-1)}{-2 - (-8)} =0.75$

Again, rate of change of y with respect to x will be from the second two pair of values is = $\frac{12.5 - 3.5}{10 - (-2)} =0.75$

And, rate of change of y with respect to x will be from the third two pair of values is = $\frac{20-12.5}{20 - 10} =0.75$

So, the rate is always 0.75.

Therefore, a proportional relationship is there. (Answer)

Valentin [98]

The original price for one lunch special is $19.

<em><u>Explanation</u></em>

The original price for one lunch special is 'p' dollar.

He wins a coupon for $4 off for each of five days. That means , <u>he needs to pay $(p-4)$ dollar each day</u>.

So, the total amount needed to pay for 5 days $= 5(p-4)$ dollar

Given that, <u>he pays $75 for his 5 lunch specials</u>. So the equation will be.....

$5(p-4)= 75\\ \\ 5p-20=75\\ \\ 5p= 75+20\\ \\ 5p= 95\\ \\ p=\frac{95}{5}=19$

So, the original price for one lunch special is $19.
