Answer:

Step-by-step explanation:

$25\pi + (8*10\pi)+[(35*12)-25\pi]+(35*12)+ 2(15*12)+2(35*15)=\\25\pi +80\pi + (420-25\pi) + 420 + 360 + 1050=\\105\pi-25\pi + 840 +1410=\\80\pi+2250=\\2501.32741229$

Need a refresh on scientific notation? help.

Dmitrij [34]

Scientific notation can be scary but it really is simple
the exponent after the 10 is how many places you move the decimal. If it is positive you move it right, if it negative you move it left
2 x 10^2 means you move the decimal place right twice to make 200
4 x 10^-3 means you move the decimal place left three times to make .004
The question is asking you to multiply 900000 and .0000006

A soft drink machine outputs a mean of 24 ounces per cup. The machine's output is normally distributed with a standard deviation

Arisa [49]

Answer:

$P(21$

And we can find the probability with this difference

$P(-1$

And using the normal standard distribution or excel we got:

$P(-1$

Step-by-step explanation:

Let X the random variable that represent the soft drink machine outputs of a population, and for this case we know the distribution for X is given by:

$X \sim N(24,3)$
