Hello!
If William originally won 50 tickets, redeemed 30, and gave 5 to his friend, the expression that represents how many tickets he has left is:
50-30-5
If you are looking for how many tickets William has left, you simply need to solve the expression:
50-30-5 = 15
I hope this helps you! Have a great day!
Answer: 60= $3.00 and 30= $4.00
x=# of $3 tickets
90-x=# of $4 tickets
$3x+$4(90-x)=$300
3x+360-4x=300
-x+360=300
-x=-360+300
-x=-60
x=60 $3 tickets
90-60=30 $4 tickets
Answer:
p-value of the statistics = 0.0096
Step-by-step explanation:
Given - The mayor of a town has proposed a plan for the annexation of an adjoining bridge. A political study took a sample of 1500 voters in the town and found that 47% of the residents favored annexation. Using the data, a political strategist wants to test the claim that the percentage of residents who favor annexation is above 44%.
To find - Determine the P-value of the test statistic.
Proof -
Given that,
H0 : p = 0.44
Ha : p > 0.44
Now,
Test Statistics is
z = (p bar - p)/ sqrt(p(1-p)/n)
= (0.47 - 0.44) / sqrt(0.44(1-0.44)/1500)
= 2.34
⇒z = 2.34
So,
p-value = P(Z > z)
= P(Z > 2.34)
= 0.0096
⇒p-value = 0.0096
