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.
Answer:
6s(5k+3)
Step-by-step explanation:
18s+30sk
Factor out 6.
6(3s+5sk)
Consider 3s+5sk. Factor out s.
s(3+5k)
Rewrite the complete factored expression.
6s(5k+3)
There are 40 cats in the ecosystem.
You set 1/5 equal to x/200. Then you cross multiply the fractions to get 5x=200. You divide both terms by 5 to get x, which equals 40.
Answer:
80 degrees
Step-by-step explanation:
they are adjacent angles -
115-35=80
GBE=80 degrees
You need to find the hypotenuse of the right triangle.
4² + 9² = c²
16 + 81 = c²
97 = c²
9.85 = c
There are 5,280 ft in a mile.
Multiply 9.85 by 5,280.
9.85 × 5,280 = 52,008
Multiply 52,008 by 110.
52,008 × 110 = <span>5,720,880
The estimated cost for constructing the street would be $</span>5,720,880.
