What is the value of the natural logarithm when x =0.6 is rounded to the nearest hundredth

Bezzdna [24]

We are tasked to determine the natural logarithm when x = 0.6.
x = 0.6, applying natural logarithm on both sides, we have it:
ln x = ln 0.6 using a scientific calculator, enter ln 0.6 and then this would give an answer of -0.5108256238
As per instruction, we are required to round the answer to the nearest hundredth such as the final answer is -0.51.

The answer is the letter "B".

Hello,

So we can first assign HD videos and classic videos to specific variables, x is HD videos and y is classic videos.

Fiona bought 5 HD videos, and 2 classic videos for 31 dollars.
5x + 2y = 31

Iliana bought 3 HD videos and 5 classic videos for 30 dollars.
3x + 5y = 30

Therefore, the final answer is choice D, 5x + 2y = 31 and 3x + 5y = 30.

tekilochka [14]

Answer:

a) 25

b) 49

c) 97

Step-by-step explanation:

The sample size is calculated using the formula, n = $(\frac{\sigma\times z}{\textup{Margin of error}})^2$

Now,

for 95% confidence level value of z-factor = 1.96

Given:

Mean = $3.94

standard deviation = $0.25

thus,

a) for margin of error = $0.10

n = $(\frac{\sigma\times z}{\textup{Margin of error}})^2$

or

n = $(\frac{0.25\times1.96}{\textup{0.10}})^2$

or

n = 4.9²

or

n = 24.01 ≈ 25 (Rounded off to next integer)

b) for margin of error = $0.07

n = $(\frac{\sigma\times z}{\textup{Margin of error}})^2$

or

n = $(\frac{0.25\times1.96}{\textup{0.07}})^2$

or

n = 7²

or

n = 49

c) for margin of error = $0.05

n = $(\frac{\sigma\times z}{\textup{Margin of error}})^2$

or

n = $(\frac{0.25\times1.96}{\textup{0.05}})^2$

or

n = 9.8²

or

n = 96.04 ≈ 97 (Rounded off to next integer)
