The slope for both the line is m= 1/3 and  they are parallel lines , Option B and C are correct two options

The first equation is

 y = (1/3)x-4 and not y = -x-4

(if the equation is not corrected then it will not have two true statements)

<h3>What is a System of Equation ?</h3>

A system of equation is a set of equation which have a common solution

The given system of equation is

y = (1/3)x-4

3y -x = -7

3y = x-7

As it can seen from the standard equation of a line that

y =mx+c

so slope for both the line is m= 1/3

Therefore they are parallel lines

Thus , Option B and C are correct two options

in a poll about work, 62% of respondents said that their jobs were sometimes or always stressful. twelve workers are chosen at r
Sladkaya [172]

The mean and standard deviation of number who find their jobs stressful are 7.44 and 1.6814 respectively.

Given,

number of workers chosen , n=12

percentage of respondents =62%

from given data the calculation are done according to binomial distribution,

then,

probability of respondents ,p=\frac{62}{100}=0.62

a)calculating mean,

\mu=n*p\\\\\mu=12*0.62\\\\\mu=7.44

b)calculating standard deviation,

\sigma=\sqrt{n*p*(1-p)}\\\\\sigma=\sqrt{12*0.62*(1-0.62)}\\\\\sigma=\sqrt{7.44(0.38)}\\\\\sigma=\sqrt{2.8272}\\\\\sigma=1.6814

Thus, the mean and standard deviation of number who find their jobs stressful are 7.44 and 1.6814 respectively.
