Answer:
36 meters^2
Step-by-step explanation: Because a square is equal on all sides, and there are 4 sides on a square, you need to divide the perimeter by 4. When you do this you will get 6. Now to find the area, you need to do 6x6, which equals 36.
Is this a function {(2,5),(3,6),(5,2),(0,5),(8,1),(9,3)}

Answer:
Yes
Step-by-step explanation:
To be a function, no two x-values can be the same in a set of coordinates.
2, 3, 5, 0, 8, and 9 do not equal each other, so it is a function.
Answer:
D. Fail to reject the null hypothesis. There is enough evidence to oppose the gaming company's claim.
Step-by-step explanation:
Let μ = mean time to complete a role-playing game.
The company claims that their role-playing games take <u>over</u> 65 hours to complete, so the hypotheses are:
H₀: μ = 65 H₁: μ > 65
Therefore, this is a one-tailed test.
The significance level is 1%, so α = 0.01.
Find the value of the test statistic (z):
Using the “Percentage Points of The Normal Distribution” table, the critical value is z = 2.3263 meaning the critical region is Z > 2.3263.
Since z = -3.4641... < 2.3263, the observed value of the test statistic lies outside the critical region. Therefore, the result is not significant.
<u>Conclusion</u>
There is sufficient evidence at the 1% level of significance to fail to reject H₀ and to oppose the alternative hypothesis that the mean time to complete the role-playing game is more than 65 hours.
