For one it would be the mass because liquid isn’t measured in grams
Answer:
Option A. (4,0) and (-1,0)
Step-by-step explanation:
we know that
The equation of a vertical parabola in factored form is equal to
where
a is a coefficient
x_1 and x_2 are the zeros or x-intercepts of the function
In this problem we have
we have
The leading coefficient is negative, that means the parabola open downward
The zeros of the function are
Remember that the x-intercepts are the values of x when the value of the function is equal to zero
therefore
The x-intercepts are (4,0) and (-1,0)
Answer:
The correct answer is B: ∠DGB is supplementary to ∠CGB. I got it right on my test.
Step-by-step explanation:
Answer:
1)Mean=920 $
2)Standard Error =S.E.=38
3)more likely to take place Event 25 studio apartments with a mean rent between $901 and $939
Step-by-step explanation:
Given:
True mean =920 $
S.D=190 $
No .of samples=25
To Find:
1)Mean of sample.
2)S.E
Solution:
Now , the mean for given sample distribution is given as 920 $
Hence Mean =920 $
Now calculating the Standard error
S.E.= S.D./Sqrt(n)
=190/Sqrt(25)
=190/5
=38
Therefore the Standard error is about 38 .
a) When n=1 then P(901≤X≤939)
So,
Z1=(901 -920)/190/Sqrt(1)]
Z1=-0.1
Z2=(939-920)/(190/Sqrt(1)]
Z2=0.1
So
Pr(-0.1≤Z≤0.1)=P(Z≤0.1)-P(Z≤-0.1)
=0.5398-0.4602
=0.0797 % chance of the sample distribution
b)n=25 then P(901≤X≤939)
Z1=(901-920)/S.E
Z1=-19/38=
Z1=-0.5
And Z2=0.5
So,
Pr(-0.5≤Z≤0.5)
=Pr(Z≤0.5)-Pr(Z≤-0.5)
=0.6915-0.3085
=0.3829
i.e 38.29 % chance of the sample distribution
Hence More likely to take place will be a sample of 25 studio apartments with a mean rent between $901 and $939.
0.3829>0.0797.
Because the probability of causing above event is more than the option A.
1/2 because it is a fraction
