Adrian paid $465.60 for 120 rubber pads for the bottom of his store's chairs. How much did Adrian pay for each rubber pad? Dameo

Semmy [17]

Dameon's answer should be closer to $0.40 as the real cost is $3.88 per rubber pad

You can find this by $465.60 by 120

Find the sample size necessary in order to be 95% confident when determining the true mean weight within 2 units (EC2). Assume t

bogdanovich [222]

Answer:

Step-by-step explanation:

Given:

Margin of error (E) = 2

Sample variance $(s^{2})$ = 44

Confidence level = 95%

The z- value at 95% confidence level is 1.96.

The sample using the provided information can be calculated as:

$n=(\frac{z(s)}{E})^{2} \\n=\frac{z^{2} s^{2} }{E^{2} } \\n=\frac{1.96^{2} (44) }{2^{2} }\\n= 42.52\\n=43$

Hence, the correct option is (c) 43.

Twice a number, added to seven, is the same

eduard

Answer:

Your number is -10

Hope this helps :)

Step-by-step explanation:

Let x be the number

Twice a number is 2x

Added to 7 means + 7 so 2x + 7

Is means =

2x+7=

At this point I have to assume you mean

"is the same as three subtracted from THE SAME number"

Otherwise, rather than a number, we end up with the

equation of a line....

2x + 7 = x - 3 subtract x from both sides

x + 7 = -3 subtract 7 from both sides

x = -10

Your number is -10

Check: 2x+7 = x-3

2(-10) + 7 = -10-3

-20+7 = -13

-13 = -13

The answer fits the parameters of the problem.

Substitute $u=\ln x$ , so that $\mathrm du=\dfrac{\mathrm dx}x$ . The integral is then equivalent to

$\displaystyle\int\frac{\mathrm dx}{x\ln^px}=\int\frac{\mathrm du}{u^p}=\begin{cases}\dfrac{u^{p+1}}{p+1}+C&\text{for }p\neq1\\\\\ln|u|+C&\text{for }p=1\end{cases}$

Then transforming back to $x$ gives

$\displaystyle\int\frac{\mathrm dx}{x\ln^px}=\begin{cases}\dfrac{\ln^{p+1}x}{p+1}+C&\text{for }p\neq1\\\\\ln|\ln x|+C&\text{for }p=1\end{cases}$
