Answer:
$7.20
Step-by-step explanation:
60% of 4.5 = 2.7
4.5+2.7 = $7.2
There are one, tens and seven, ones in seventeen
Hope this helped!!
so the basic formula for this d = rt
where d is the distance , r is the speed and t
is time
3800 – 120t = 520 + 40t ( this is the altitude
of each plane are equal)
Solve for t
T = 20.5 min time it takes for the planes to be
at the same altitude
3800 – 120(20.5) = 1340 ft

Answer:
The answer is -1.2
Step-by-step explanation:
Recalling the standard deviation formula,
we have : σ = sqrt[ P * ( 1 - P ) / n ]
Where sqrt = square root
n = Number of derivative
Therefore,:
if, H0: p is not 48% vs H1: p1 = 48%
standard deviation is:
σ = sqrt[ P * ( 1 - P ) / n ] = sqrt[ .48*.49/900 ] = .01666333+
z -score is (p-P)/σ
= (.51-.53)/.01666333
The answer therefore = -1.2
ICONCLUSION:
It can therefore be concluded that there is statistical evidence that the proportions are different. H0 accepted in the hypothesis.
