What is the value of n in the equation below? a^n/a^3=a^9

Levart [38]

Answer:

Step-by-step explanation:

using the rules of exponents

• $a^{m}$ × $a^{n}$ = $a^{(m+n)}$

given $\frac{a^{n} }{a^{3} }$ = $a^{9}$

multiply both sides by $a^{3}$

$a^{n}$ = $a^{9}$ × $a^{3}$ = $a^{12}$

since bases on both sides are a, equate the exponents, hence

n = 12 → C

A random sample of 40 college students has a mean earnings of $3120 over the summer months. Assume the population standard devi

PSYCHO15rus [73]

Answer:

A normal distribution or z-test is used to construct a confidence interval.

Step-by-step explanation:

We are given the following in the question:

Sample mean, $\bar{x}$ = $3120

Sample size, n = 40

Population standard deviation, σ = $677

The distribution of earnings of college is a normal distribution.

Conditions:

Since we are given the population standard deviation and the the sample size is also greater than 30.

Conclusion:

Thus, we use a normal distribution or z-test to construct a confidence interval.

Find m< s <br> Please please help

Nadusha1986 [10]

Answer:

m< s = 43

Step-by-step explanation:

77 + 2x + 3 = 6x (collect like terms)

80 + 2x = 6x (subtract 2x on both sides)

80 = 4x (divide both sides by 4)

20 = x

PLUG IN TO M<S

2(20) + 3

40 + 3

m<s = 43

Hope this helps ya! Keep smiling!
