If (-2) = -14 for f(x) = 3x -b; find b? -
Verizon [17]

Answer:

<em>The value of b is</em><em> 8</em><em>.</em>

Step-by-step explanation:

The given function is,

f(x) = 3x -b

The given data is,

f(-2)=-14

i.e when the value of x is -2, then the value of the function is -14.

Putting all the values,

\Rightarrow -14 = 3(-2) -b

\Rightarrow -14 = -6 -b

\Rightarrow b=-6+14

\Rightarrow b=8

Therefore, the value of b is 8.

puteri [66]

Answer:

n=(\frac{2.17(0.143)}{0.023})^2 =182.03 \approx 183

So the answer for this case would be n=183 rounded up to the nearest integer

Step-by-step explanation:

Information provided

\bar X represent the sample mean

\mu population mean (variable of interest)

\sigma = 0.143 represent the population standard deviation

n represent the sample size  

ME = 0.023 the margin of error desired

Solution to the problem

The margin of error is given by this formula:

ME=z_{\alpha/2}\frac{\sigma}{\sqrt{n}}    (a)

And on this case we have that ME =0.023 and we are interested in order to find the value of n, if we solve n from equation (a) we got:

n=(\frac{z_{\alpha/2} \sigma}{ME})^2   (b)

The confidence level is 97% or 0.97 and the significance would be \alpha=1-0.97=0.03 and \alpha/2 = 0.015 then the critical value would be: z_{\alpha/2}=2.17, replacing into formula (5) we got:

n=(\frac{2.17(0.143)}{0.023})^2 =182.03 \approx 183

So the answer for this case would be n=183 rounded up to the nearest integer

Van found the change in a scale factor. His work is shown below. What error did Ivan make?
8090 [49]

Answer:

Ivan wrote the ratio incorrectly. The ratio should be written as the old length to the new length, so it should be 35

10

, which reduces to 7

2

. When going from larger to smaller dimensions, the change in the scale factor is a ratio that looks like an improper fraction, with a larger number in the numerator and a smaller number in the denominator.
