B is your answer! All you do for this equation is go oh look m=2/7 well this means y=2/7x and you have a -12 so than you just plug it in. To get y=2/7x-12
Answer:
A. y = 7/3x + 2
Step-by-step explanation:
14x = 6y - 12
14x + 12 = 6y
y = 7/3x + 2
Answer:C and E
Step-by-step explanation:
Answer:
mean age of women
(x+y+z)/3=27
mean age of men
(x1+x2+x3+x4+x5+x6)/6=34
mean age of all people in the office
x+y+z=27*3=81
x1+...x6=34*6=204
so
mean age( x+y+z+x1+x2+..x6)/(3+6)=(27*3+34*6)/9
=(81+204)/9=285/9=32 approximately
Answer:
No evidence .because the configurations factors and failure mode are independent
Step-by-step explanation:
Determine if there is sufficient evidence to conclude that configuration affects the type of failure
Number of configurations = 3
Number of failures = 4
assuming <em>Pij </em>represents proportion of items in pop i of the category j
H0 : <em>Pij = Pi * </em>Pj<em>, </em>I = 1,2,-- I, j = 1,2,---J
Hence the expected frequencies will be
16.10 , 43.58 , 18, 12.31
7.5, 19.37, 8 , 5.47
10.73, 29.05, 12, 8.21
x^2 = 13.25
test statistic = 14.44. Hence the significance level where Null hypothesis will be acceptable will be = 2.5%
