What is the value of n in the equation below? a^n/a^3=a^9
Levart [38]

Answer:

C

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

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:

Find m&lt; 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!
