Answer:
The approximate probability that more than 360 of these people will be against increasing taxes is P(Z> <u>0.6-0.45)</u>
√0.45*0.55/600
The right answer is B.
Step-by-step explanation:
According to the given data we have the following:
sample size, h=600
probability against increase tax p=0.45
The probability that in a sample of 600 people, more that 360 people will be against increasing taxes.
We find that P(P>360/600)=P(P>0.6)
The sample proposition of p is approximately normally distributed mith mean p=0.45
standard deviation σ=√P(1-P)/n=√0.45(1-0.45)/600
If x≅N(u,σ∧∧-2), then z=(x-u)/σ≅N(0,1)
Now, P(P>0.6)=P(<u>P-P</u> > <u>0.6-0.45)</u>
σ √0.45*0.55/600
=P(Z> <u>0.6-0.45)</u>
√0.45*0.55/600
Let's organize.
The question says to <u>identify</u> an <u>equation in point-intercept form</u> for the <u>line</u> that's <u>parallel</u> to y = -3x + 7 that <u>passes through</u><u /> (2, -4).
If you need to find an equation in point-intercept form that passes through a point, you will substitute the coordinate in this formula:
-> y - yo = m (x - xo)
Where:
(2, -4) -> xo = 2 ; yo = -4
m = Slope
You don't have the slope, but you have the information that the line is <u>parallel</u> to <u />y = -3x + 7. Then you need to know that to a line be <u>parallel to another</u> the Slopes of each other must be equal, mr = ms.
Let's find the slope of the equation given, it is in a slope-intercept form, so:
y = mx + b
R: y = -3x + 7 // I will call this one R line, and the other S.
mr = -3
If the mr = ms, and mr = -3, then the ms = -3 too.
S: y - yo = ms (x - xo) // (2, -4) & ms = -3
-> y - (-4) = -3 (x - 2)
-> S: y + 4 = -3 (x - 2) -> This is the point-slope form.
-> y = -3x + 6 - 4
-> S: y = -3x - 2 -> This is the slope-intercept form.
I didn't understand what is the point-intercept form that the question requests, but by logic, i think that's the point-slope form.
Answer: The equation in point-intercept form is: y + 4 = -3 (x - 2).
Divide 25 by 3 and you find 8.something. so if u need the gallon cooler to be empty the awnser would be 9 minutes
