Hi!
The only true answer is DX = AX.
Hope this helps!
274%
= 274/100
= 2.74
The final answer is 2.74~
Answer:
6x
Step-by-step explanation:
Area of triangle = l x w => 2x x 3x = 6x
Answer:
Kindly check explanation
Step-by-step explanation:
H0 : μ = 5500
H1 : μ > 5500
The test statistic assume normal distribution :
Test statistic :
(Xbar - μ) ÷ s/sqrt(n)
(5625.1 - 5500) ÷ 226.1/sqrt(15) = 2.1429 = 2.143
Pvalue from test statistic :
The Pvalue obtained using the calculator at df = 15 - 1 = 14 is 0.025083
α = 0.05
Since ;
Pvalue < α
0.025083 < 0.05 ; Reject H0
The confidence interval :
Xbar ± Tcritical * s/sqrt(n)
Tcritical at 95% = 1.761 ;
margin of error = 1.761 * 226.1/sqrt(15) = 102.805
Lower boundary : (5625.1 - 102.805) = 5522.295
(5522.295 ; ∞)
The hypothesized mean does not occur within the constructed confidence boundary. HENCE, there is significant eveidbce to support the claim that the true mean life of a biomedical device is greater than 5500
Answer:
there is no solution
Step-by-step explanation:
1st switch sides: -x2+2x+1=0
2nd add similar elements: -2x + 2x = 0
1 = 0
Thus, this equation has no solution
hope i helped :)
