Let b = width
l = length
Then, l = 2b - 2 ----------(i)
and, Perimeter = 86 cm
=> 2(l+b) = 86
=> 2b - 2 + b = 86/2
=> 3b = 43 +2
=> b = 45/3 = 15
=> b = 15
Putting the value of b in equation(i)
And, l = 2×15 - 2
= 30-2
= 28
Hence, length = 28 cm
width = 15 cm

Suppose you want to estimate the proportion of polydactyl cats (cats with extra toes). You sample 419 randomly selected cats, an
german

Answer:

No. When all you want to do is estimate a population parameter, you should construct a confidence interval.

Step-by-step explanation:

In this case, there is no other prior estimation about the population to test (a hypothesis to nullify). The only thing you can do is construct a confidence interval of the proportion, where the standard deviation can be calculated in function of the proportion and the sample size.

The right answer is E: "No. When all you want to do is estimate a population parameter, you should construct a confidence interval."

So it's actually 0.36363636... with the 36 repeating, right? 

<span>Here's a technique for converting repeating decimals to fractions: </span>

<span>N = 0.3636363636... </span>
<span>100N = 36.36363636... </span>

<span>This means 100N - N = (36.363636...) - (0.36363636...). This simplifies to 99N = 36, because the "0.36363636..." parts of both numbers on the right cancel each other out. </span>

<span>Solving this for N gives </span>
<span>N = 36/99, or 4/11 </span>

<span>If you take a calculator (or use long division) and divide 4 by 11, you'll see that it's 0.36363636...</span>

If 2x -3(x+4)=-5, Then x=​
kherson [118]
The answer is -7

2x-3(x+4)=-5

Multiply by -3

2x-3x-12=-5

Collect like terms

-x-12=-5

Move constant to the right to change its sign

-x=-5+12

Add

-x=7

Change the signs

x=-7
