Answer:
The probability that a person will get 17 or more right, if the person is truly guessing, is about 12.9%.
The p-value is the probability of obtaining the observed results of a test, assuming that the null hypothesis is correct.
Step-by-step explanation:
The system of hypothesis fo this case are:
Null hypothesis: 
Alternative hypothesis: 
That's a upper right tailed test.
The p-value is the probability of obtaining the observed results of a test, assuming that the null hypothesis is correct.
And this value allows to reject or not the null hypothesis.
If 
we reject the null hypotheis at the significance level. That indicates strong evidence against the null hypothesis, so you reject the null hypothesis.
If 
then we say that we fail to reject the null hypothesis at the significance level. That indicates weak evidence against the null hypothesis, so you fail to reject the null hypothesis.
Answer:
D. 20 + 2.50x < 50
Step-by-step explanation:
20 + 2.50x < 50 - the sign has to be less than because Millie wants to spend less than $50
-(q + 14) = -3 + (-14)
-q - 14 = -3 -14
-q - 14 = -11
-q = +14 - 11
-q= 3
Answer:
126°
Step-by-step explanation:
the total max percent can be 100%
OR
The total value of the pie is 100%
that means all sectors must add upto 100
=> x + x + 21 + 9 = 100
=> 2x + 30 = 100
=> 2x = 70
=> x = 35
therefore, the two large sectors which are both equal to x each represents 35% of the whole.
<u>Angle subtended by one of those large sectors</u> :-
therfore, the central angle of the big sector is<u> 126°</u>
The first time I did the math including 8 but we are increasing it so it will just be how much did the price increase from 8 to 18 well I know 100% of 8 is 8 so thats 100% and 25% of 8 is 2 so I added the two and 8 + 8 = 16 + 2 = 18 I added those percents 100 + 25 = 125%
