Answer:

Total number of marbles = 12

P (1 red & 1 orange) =

\frac{1 + 1}{12}  \\  =  \frac{2}{12}  \\  =  \frac{1}{6}  \\  = 0.16

Answer:solution given:

total no of marbles [S]=12

total no of red marbles[R]=5

total no of green marbles[G]=3

total no of yellow marbles[Y]=2

total no of orange marbles[O]=2

now

the P( red, then orange) n[p]=?

we have

n[p]=\frac{n[R]+n[O]}{n[S]}

n[p]=\frac{5+2}{12}

n[p]=\frac{7}{12}

the P( red, then orange) n[p]=\frac{7}{12}

A textile fiber manufacturer is investigating a new drapery yarn, which the company claims has a mean thread elongation of 12 ki
shepuryov [24]

Answer

given,

mean = 12 Kg

standard deviation = 0.5 Kg

assume the observed statistic is = 11.1

 now, \bar{X}=11.1 , \mu = 12 , \sigma = 0.5

assuming the number of sample = 4

n = 4

Hypothesis test:

H₀ : μ≥ 12

Ha : μ < 12

now,

significant level α = 0.05

z* = \dfrac{\bar{X}-\mu}{\dfrac{\sigma}{\sqrt{n}}}

z* = \dfrac{11.1-12}{\dfrac{0.5}{\sqrt{4}}}

     z* = -3.60

Test statistics, Z* = -3.60

P-value

P(Z<-3.60) = 0.002 (from z- table)

P- value = 0.002

now,

reject the value of H₀ when P-value < α

    0.002 < 0.05

since, it is less P-value < α , we have to reject the null hypothesis

This graph shows a proportional relationship.<br> What is the constant of proportionality?
krek1111 [17]

hookes law gives the equation F=kx where F is the elastic force and k is the constant and x or small e is extension if we draw a graph you'll see that the graph increases by the same ratio every single time hence giving a straight line show that they are F and x are propotional to a certain limit
