Answer:
x = 
Step-by-step explanation:
Given
x - 5 = 
Multiply through by 8 ( the LCM of 4 and 8 ) to clear the fractions
6x - 40 = 3 ( add 40 to both sides )
6x = 43 ( divide both sides by 6 )
x =
Answer:
the answer is x=2 and y=3
Step-by-step explanation:
y=3 for x=2
y=3;x=2
x=2 and y=3
Square root of 12-1 = 3.32
5/2 = 2.5
2.25
1+(3.14/2) = 2.57
Greatest to least: Square root of 12-1, 1+3.14/2, 5/2, 2.25
Answer:
Hence from the given value male and female.
From this confidence intervals do not overlap so adult females have higher rate than adult males.
Step-by-step explanation:
Taking mean for female = 3025 / 40 = 75.6
taking mean for male = 2666/40 =66.65
Construction of hypothesis:
For 90 % confidence interval for adult female :
72.0 bpm <μ<75.2 bpm
For 90 % confidence interval of adult females:
66.65 bpm<μ<70.6 bpm
From this confidence intervals do not overlap so adult females have higher rate than adult males.
Answer:
EY = 60
DW = 68
DE = 128
Step-by-step explanation:
Given
As YW is the perpendicular bisector of EF, then EY = FY
FY = √(FW² - YW²) = √(68² - 32²) = 60
⇒ EY = 60
As WX is the perpendicular bisector of DF, then DW = FW
As FW = 68, then DW = 68
As WZ is the perpendicular bisector of DE, then DZ = EZ = 64
Therefore, DE = DZ + EZ = 64 + 64 = 128
