Answer:

we do not reject the null hypothesis

Step-by-step explanation:

The critical value depends on the form of the alternative hypothesis, in particular, whether the test is two-sided, one-sided on the left, or one-sided on the right. For a given test, the critical value can be seen as the limit value from which we can reject the null hypothesis with a given significance threshold. So, in a hypothesis test, if the test statistic is less extreme than the critical value, we do not reject the null hypothesis. But if the test statistic is more extreme than the critical value, we reject the null hypothesis.

in a standard casino dice game the roller wins on the first roll if he rolls a sum of 7 or 11. what is the probability of winnin

Alborosie

Answer-

The probability of winning on the first roll is 0.22

Solution-

As in the game of casino, two dice are rolled simultaneously.

So the sample space would be,

$|S|=6^2=36$

Let E be the event such that the sum of two numbers are 7, so

E = {(1,6), (2,5), (3,4), (4,3), (5,2), (6,1)}

$|E|=56$

$\therefore P(E)=\dfrac{|E|}{|S|}=\dfrac{6}{36}$

Let F be the event such that the sum of two numbers are 11, so

F = {(6,5), (5,6)}

$|F|=2$

$\therefore P(F)=\dfrac{|F|}{|S|}=\dfrac{2}{36}$

Now,

$P(\text{sum is 7 or 11)}=P(E\ \cup\ F)=P(E)+P(F)=\dfrac{6}{36}+\dfrac{2}{36}=\dfrac{8}{36}=\dfrac{2}{9}=0.22$

Answer:

41.86 miles each hour

Step-by-step explanation:

Kelli and her family went to the beach for a vacation. They drove 293 miles in 7 hours to get there. ABOUT how many miles did they drive each hour?

This Question is calculated as:

7 hours = 293 miles

1 hour = x miles

Cross Multiply

7 hours × x = 1 × 293 miles

x = 293 miles/7 hours

x = 41.857142857 miles per hour

x ≈ 41.86 miles per hour

Hence, they drove 41.86 miles each hour

You increase the size of a computer screen display by 20 %

Eva8 [605]

Assuming display of computer is at 100%
So increase by 20% = 120 (20/100 *100)
then 20% of 120 is: 20/100 * 120 = 24

So the display is now 120-24 = 96

Hope this helps!
