Hi, Please i need help with this question. Workings would be deeply appreciated .
kupik [55]

Answer:

k = ⅕  

Step-by-step explanation:

The slope-intercept equation for a straight line is

y = mx + b, where

m = the slope and

b = the y-intercept

Data:

(3,4)     = a point on the line

(3k,0)   = x-intercept

(0,-5k) = y-intercept

Calculations:

1. Slope

m = (y₂ - y₁)/(x₂ - x₁) = (-5k - 0)/(0 - 3k) = -5/(-3) = ⁵/₃

This makes the equation

y = ⁵/₃x - 5k

2. k

Insert the value of the known point: (3,4)

4 = (⁵/₃)(3) - 5k

4 = 5 - 5k

-1 = -5k

k = ⅕

The figure below shows your graph passing through (3,4) with intercepts 3k and -5k on the x- and y-axes respectively .

QveST [7]

Answer: z= -1.636

Step-by-step explanation:

When population standard deviation is known, then the test statistic is given by :-

z=\dfrac{\overline{x}-\mu}{\dfrac{\sigma}{\sqrt{n}}}

, where \overline{x} = sample mean, \mu = population mean, n=sample size , \sigma = standard deviation

As per given,

z=\dfrac{55.82-56}{\dfrac{0.77}{\sqrt{49}}}\\\\ z=\dfrac{-0.18}{\dfrac{0.77}{7}}\\\\z=\dfrac{-0.18}{0.11}\\\\z=-1.636

Hence, the e test statistic to see whether the candy bars are smaller than they are supposed to be : z= -1.636
