Helpp pls Let x denote the number of broken pencils in a randomly selected 50-count box from a local office supply store. The variable x has the following probability distribution:

x01234
P(X)0.520.350.10.020.01
Calculate and interpret σx. (4 points)

A-0.82; if we were to select many boxes of pencils randomly, the number of broken pencils would typically vary about 0.82 from the mean

B-0.31; if we were to select many boxes of pencils randomly, we would expect about 0.31, on average, to contain broken pencils

C-0.65; if we were to select many boxes of pencils randomly, the number of broken pencils would typically vary about 0.65 from the mean

D-0.52; if we were to select many boxes of pencils randomly, we would expect about 0.52 to have no broken pencils

E-0.13; if we were to select many boxes of pencils randomly, we would expect about 0.13, on average, to contain broken pencils

step-by-step explanation:

i think something is missing in your question because y-1=(x-12) would not pass through the point (-4,-3). because if you replace x by -4 your are supposed to find y=-3 which is not the case her. if you replace x by -4 you find =-15.

i assume the right equation is y-1=1/4*(x-12) because this one is passing through both your points (if you are interested to know how i found that out i can tell you).

in this equation if i replace x by -4 i find y=-3 and if i replace x by 12, i find y=1 so the line representing this equation is passing through those 2 points.

then the standard form of the equation is finding an expression of y in function of x

y-1=1/4*(x-12)

y=x/4-3+1

y=x/4-2

hope that .

do you confirm there was a mistake in the question?

answer: solve 5\cdot 2^x=2405⋅2  

x

=2405, dot, 2, start superscript, x, end superscript, equals, 240.

solution

to solve for xxx, we must first isolate the exponential part. to do this, divide both sides by 555 as shown below. we do not multiply the 555 and the 222 as this goes against the order of operations!

\begin{aligned} 5\cdot 2^x& =240 2^x& =48 \\ \end{aligned}  

5⋅2
