5x+4y = 73
-4x + 4y = -8
5x + 4y -(-4x+4y) = 73 -(-8)
5x + 4y + 4x - 4y = 81
5x + 4x + 4y - 4y = 81
9x = 81
x = 81÷9
x = 9
Substitute x = 9 into any of the equations to find y.
5(9) + 4y = 73
45 + 4y = 73
4y = 73 - 45
4y = 28
y = 28÷4
y=7

Should be the correct answer.
We cannot reject the null hypothesis as the p value is less than 0.01.
<h3>How to illustrate the hypothesis?</h3>
From the information given, Luiza wants to go on a popular talent TV show and in order to be accepted, her audition must get at least 60% positive votes from the people in the crowd.
The observed outcome also has a probability less than 1% under the tested hypothesis. Based on the information, the test statistic will be - 1.58.
After this, this will be checked under the standard normal distribution table where the p value will be 0.0571.
Based on this information, we cannot reject the null hypothesis as the p value is less than 0.01.
In conclusion, the correct option is that we cannot reject the hypothesis.
