triangle has sides measuring 2 inches and 7 inches If x represents the length in inches of the third side which inequality gives
il63 [147K]
We know that
The sum of the lengths of any two sides of a triangle is greater than the length of the third side (<span>Triangle Inequality Theorem)
so
inequality 1
</span>(2+7) \ \textgreater \  x \\  9 \ \textgreater \  x \\  x \ \textless \  9 in
<span>
inequality 2
</span>(x+2) \ \textgreater \  7 \\  x \ \textgreater \  7-2 \\  x \ \textgreater \  5 in
<span>
the answer is
</span>5 in  \ \textless \ x \ \textless \ 9 in<span>
</span>

The hours a week people spend answering and sending emails is normally distributed with a standard deviation of Ï = 150 minutes.
storchak [24]

Answer:

sample size n would be 149305 large

Value of n (149305) is too high, this will be the practical problem with attempting to find this confidence interval

Step-by-step explanation:

Given that;

standard deviation α = 150 min

confidence interval = 99%

since; p( -2.576 < z < 2.576) = 0.99

so z-value for 99% CI is 2.576

E = 1 minutes

Therefore

n = [(z × α) / E ]²

so we substitute

n = [(2.576 × 150) / 1 ]²

n = [ 386.4 ]²

n = 149304.96 ≈ 149305

Therefore sample size would be 149305 large

Value of n is too high, that would be the practical problem with attempting to find this confidence interval
