What is the simplified base for the function f(x) = 2rootindex 3 startroot 27 endroot superscript 2 x?

VMariaS [17]

Applying exponential properties, the simplified base for the function is given as follows:

$f(x) = 2(3)^{2x}$

<h3>What is the function?</h3>

The function is represented by the following definition:

$f(x) = 2\sqrt[3]{27^{2x}}$

As an exponent, the function is given by:

$f(x) = 2(27)^{\frac{2x}{3}}$

27 can be simplified as follows:

27 = 3 x 3 x 3 = 3³

Hence:

$f(x) = 2(3^3)^{\frac{2x}{3}}$

Then, the 3 at the exponent multiplies 2x and can be simplified with the 3 of the root, hence:

$f(x) = 2(3)^{\frac{3 \times 2x}{3}} = 2(3)^{2x}$

Hence the simplified base for the function is given as follows:

$f(x) = 2(3)^{2x}$

Last year, 46% of business owners gave a holiday gift to their employees. A survey of business owners indicated that 20% plan to

alisha [4.7K]

Answer:

Part a: So the number of business owners giving holiday gift to their employees from survey is 12.

Part b: p-value is 0.00003

Part c: value of p is less that a we reject the null hypothesis.

Step-by-step explanation:

Part a

number of business owners=20% x n

number of business owners= 0.2x 60

number of business owners=12

Part b

H0: p=0.46

H1: p<0.46

Here

n=60, $\hat{p}$ =0.2, p=0.46

So test statistics is given as

$z=\frac{\hat{p}-p}{\sqrt{\frac{p(1-p)}{n}}}\\z=\frac{0.20-0.46}{\sqrt{\frac{0.46(1-0.46)}{60}}}\\z=\frac{-0.26}{0.064}\\z=-4.04$

p-value is P(z<-4.04)= 0.00003

Part c

As value of p is less that a we reject the null hypothesis.

Which is steeper: a road with a 12% grade or a road with a pitch of 1 in 8?

11Alexandr11 [23.1K]

Answer:

A road with a pitch of 1 in 8 is steeper.

Step-by-step explanation:

Let us convert these to the same units so that we can better compare them.

$\frac{1}{8} = 0.125$

0.125=12.5 %

As 12.5% is greater than 12%, the road with a pitch of 1 in 8 will be steeper.
