\textit{since the exponents are the same}\\
\textit{their bases must also be the same}

6-x=x\implies 6=2x\implies \cfrac{6}{2}=x\implies 3=x$

According the the U.S. Department of Education, full-time graduate students receive an average salary of $15,000 with a standard

Firdavs [7]

Answer:

Step-by-step explanation:

Given that :

population Mean = 15000

standard deviation= 1200

sample size n = 100

sample mean = 16000

The null and the alternative hypothesis can be computed as follows:

$\mathtt{H_o : \mu = 15000 }\\ \\ \mathtt{H_1 : \mu > 15000}$

Using the standard normal z statistics

$z = \dfrac{\overline X - \mu}{\dfrac{\sigma }{\sqrt{n}}}$

$z = \dfrac{16000 -15000}{\dfrac{1200 }{\sqrt{100}}}$

$z = \dfrac{1000}{\dfrac{1200 }{10}}$

$z = \dfrac{1000\times 10}{1200}$

z = 8.333

degree of freedom = n - 1 = 100 - 1 = 99

level of significance ∝ = 0.05

P - value from the z score = 0.00003

Decision Rule: since the p value is lesser than the level of significance, we reject the null hypothesis

Conclusion: There is sufficient evidence that the Dean claim for his graduate students earn more than average salary of $15,000

Jeremy is going to roll a fair 6 sided die 180 times.

bija089 [108]

Solve this by dividing the 180 by 6. This results in 30. So, each number should be rolled 30 times. There are only two numbers greater than 4. Multiply 30 by 2 to get your answer, 60.

If each exterior angle of a regular polygon measures 15°, how many sides does the polygon have?

Yuri [45]

Answer:

Step-by-step explanation:

The sum of the exterior angles of a polygon = 360°

Divide this by the size of 1 exterior angle to find number of sides, that is

number of sides = $\frac{360}{15}$ = 24
