Find the number ofhours each person worked.
x = Isaac hours
x + 4 = Ruby hours
((x + 4) * 4) = Svetlana hours
104 = x + (x + 4) + ((x + 4) * 4)
104 = 2x + 4 + 4x + 16
104 = 6x +20
104 - 20 = 6x + 20 - 20
84 = 6x
x = 14 hours
so
x = Isaac hours = 14
x + 4 = Ruby hours = 14 + 4 = 18
((x + 4) * 4) = Svetlana hours = ((x + 4) * 4) =18 * 4 = 72
Prooff: 14 +18 + 72 = 104

Answer:
there is significant evidence to support that the claim that the mean time women spend watching television less than the mean time spent by men.
Step-by-step explanation:
H0 : μw = μm
H1: μw < μm
The test statistic :
(x1 - x2) / sqrt[(sp²/n1 + sp²/n2)]
df1 = 14 - 1 = 13
df2 = 17 - 1 = 16
Pooled variance = Sp² = (df1*s1² + df2*s2²) ÷ (n1 + n2 - 2)
Sp² = ((13*4^2) + (16*4.2^2)) ÷ (13 + 16)
Sp² = 16.90
t = (12.9 - 16.4) ÷ sqrt((16.90/14 + 16.90/17))
t = - 3.5 ÷ 1.4836645
t = - 2.359
Using the Pvalue from Tscore ; at 95% ; df = 29
Pvalue = 0.0126
Pvalue < α
0.0126 < 0.05 ;
Hence, we reject the null and conclude that there is significant evidence to support that the claim that the mean time women spend watching television less than the mean time spent by men.
Where is this at?
Could you send it in comments here or something?
The answers is A x=4.5y because for whatever y is you multiply it by 4.5 and it gives you your x. Trust me. They all match too; I checked.
