Answer:
There is sufficient evidence that fuel economy goal has been attained.
Step-by-step explanation:
The hypothesis :
H0 : μ < 30.2
H1 : μ ≥ 30.2
The test statistic :
(xbar - μ) ÷ (s/√(n))
xbar = 32.12 ; s = 4.83 ; n = 50
Test statistic :
(32.12 - 30.2) ÷ (4.83/√(50))
1.92 ÷ 0.6830651
T = 2.811
Using the Pvalue from test statistic calculator :
Since we used the sample standard deviation, we use the T distribution
df = n - 1 = 50 - 1 = 49
Pvalue(2.811, 49) ; one tailed = 0.00354
At α = 0.05
Pvalue < α ; then we reject the null and conclude that there is sufficient evidence that fuel economy goal has been attained
y = - 4
collect terms in x
xy + 4x = 1 - 20 = - 19 ( factor out x )
x(y + 4 ) = - 19 ( divide both sides by ( y + 4) )
x =
x will be undefined if the denominator of the fraction is zero
y + 4 = 0 ⇒ y = - 4
x has no solution for y = - 4

Step-by-step explanation:
Answer:
A=79.2
Step-by-step explanation:
A=a+b/2*h
A=5.4+14.4/2*8
A=19.8/2*8
A=9.9*8
A=79.2
