Answer:

the standard error of the proportion is 0.0272

Step-by-step explanation:

We have that if the sample size is greater than 5% of the entire population, a finite population correction factor (fpc) is multiplied with the standard error :

fpc = \sqrt{\frac{N -n}{N -1} }

We know that N = 250 n = 91, replacing:

fpc = \sqrt{\frac{250 - 91}{250 -1} }

fpc = 0.799

Now, the formula would then be:

SE  = \sqrt{\frac{p * (1 -p)}{n} }*fpc

Now replacing, knowing that p = 0.12

SE= \sqrt{\frac{0.12 * (1 - 0.12)}{91} }*0.799

SE = 0.0272

So the standard error of the proportion is 0.0272

I have asked so many times and no one will answer. :(

Answer:

1) \frac{1}{2^7} ; 2) 11^7

Step-by-step explanation:

1) Using the Power of a Fraction Rule (\frac{a}{b} )^x = (\frac{a^x}{b^x} ),

(\frac{1}{2} )^7 = (\frac{1^7}{2^7} ), which can just be simplified to \frac{1}{2^7}.

2) Using the Negative Exponent Rule, a^{-x}  = \frac{1}{a^{x}},

(\frac{1}{11} )^{-7} = \frac{1}{\frac{1}{11^7}}, which can be simplified to 11^7.

If John's home is worth $145,300, how much is his coverage for living expenses if insurance covers 20 percent?
suter [353]
145,300 X .2 = 29,060

you multiply .2 because that is equal to 20% in decimal form, and you are finding out how much the insurance covers

therefore your answer would be 29,060 dollars

I'm having trouble figuring out how I could go about this. Can someone work it out then explain so that I know how to do this ne
skad [1K]

Answer:

RT-ST=QS-ST, because subtracting the same quantity from two lines that have been stated to be equal.

Therefore RS=TQ

Angle R=Angle Q, because it is an isosceles triangle

Triangle AR

S is congruent to ATQ.

AT=AS

Because TAS is isosceles, angles 5 and 6 are equal.

Therefore, angles 4 and 7 are equal, because they are supplementary angles of the same angle.

And angles 1 and 3 are equal, because the other two angles in the triangle are equal.

The triangles RAT and QAS are congruent with SAS.

Step-by-step explanation: Can u gimme brain plz!
