Given expression is

10 \frac{3}{7} + 19 \frac{5}{9}

Now convert mixed fraction as improper fraction as

10 \frac{3}{7} + 19 \frac{5}{9} =  \frac{10*7 + 3}{7} +  \frac{19*9+5}{9}
                                                         =  \frac{73}{7}  +  \frac{176}{9}
                                                          =  \frac{73*9 + 176 * 7}{63}
                                                         =  \frac{657 + 1232}{63} =  \frac{1889}{63}
Now we can convert \frac{1889}{63 } = 29 \frac{62}{63}

So the answer is 29 \frac{62}63}

2+cotA=1 homework help
Alex Ar [27]
2+\cot A=1\implies \cot A=-1\implies \tan A=-1

This happens whenever A=\dfrac{3\pi}4 or A=\dfrac{7\pi}4. More generally, \tan A=-1 whenever you start with one of these angles and add any multiple of \pi, so the general solution would be A=\dfrac{3\pi}4+n\pi, where n is any integer. (Notice that when n=1, you end up with \dfrac{7\pi}4.)

Weights were recorded for all nurses at a particular hospital, the mean weight for an individual nurse was 135 lbs. with a stand
Aloiza [94]
Given:
population mean, μ =135
population standard deviation, σ = 15
sample size, n = 19

Assume a large population, say > 100,
we can reasonably assume a normal distribution, and a relatively small sample.
The use of the generally simpler formula is justified.

Estimate of sample mean
\bar{x}=\mu=135

Estimate of sample standard deviation
\s=\sqrt{\frac{\sigma^2}{n}}
=\sqrt{\frac{15^2}{19}}=3.44124  to 5 decimal places.

Thus, using the normal probability table,
P(125
=P(\frac{125-135}{3.44124}
=P(-2.90593
=P(Z
=P(Z

Therefore 
The probability that the mean weight is between 125 and 130 lbs 
P(125<X<130)=0.0731166-0.0018308
=0.0712858
