To write 86.6 as a fraction you have to write 86.6 as numerator and put 1 as the denominator. Now you multiply numerator and denominator by 10 as long as you get in numerator the whole number.
86.6 = 86.6/1 = 866/10

And finally we have: 
86.6 as a fraction equals 866/10

ArbitrLikvidat [17]

Answer:

a) Sample correlation coefficient, r = 0.7411

bi) test statistic, t = 4.102

bii) P-value = 0.000736

Step-by-step explanation:

a) The formula for the sample correlation coefficient is given by the formula:

r = \frac{S_{xy} }{\sqrt{S_{xx} S_{yy} }} }

S_{xx} = 2,648,130.357\\S_{yy} = 36.7376,\\S_{xy} = 7408.225

r = \frac{7408.225}{\sqrt{2648130.357*36.7376} }

r = 0.7511

b)

i) formula for the test statistic is given by the formula:

t = \frac{r\sqrt{n-1} }{\sqrt{1 - r^{2} } }

sample size, n = 4

t = \frac{0.7511\sqrt{14-1} }{\sqrt{1 - 0.7511^{2} } }

t = 4.102

ii) Degree of freedom, df = n -2

df = 14 -2

df = 12

The P-value is calculate from the degree of freedom and the test statistic using excel

P-value =(=TDIST(t,df,tail))

P-value = (=TDIST(4.1,12,1)

P-value = 0.000736

Solve by using factorizing method:4x²-36x+81=0​
boyakko [2]

Answer:

  • x = 4.5

Step-by-step explanation:

  • 4x² - 36x + 81 = 0​
  • (2x)² - 2*2x*9 + 9² = 0           Identity  a² - 2ab + b² = (a - b)²
  • (2x - 9)² = 0
  • 2x - 9 = 0
  • 2x = 9
  • x = 4.5
