7 0

Answer:

15.22\%

Step-by-step explanation:

The population in 1981 is 46 million.

In 2011, the population increased to 53 million.

The increase in population is (53 -46)million =7 million

Now we express 7 million as a percentage of 46 million

=\frac{7}{46}*100\%

=0.1522*100\%

=15.22%

jek_recluse [69]
The probability is 1/462.

To find this, we will find the number of combinations of 5 country songs taken 5 at a time, 6 pop songs taken 0 at a time, and the total number of outcomes will be 11 songs taken 5 at a time:

\frac{_5C_5\times_6C_0}{_{11}C_5}
\\
\\\frac{\frac{5!}{5!0!}\times\frac{6!}{0!6!}}{\frac{11!}{5!6!}}=\frac{1\times1}{\frac{11!}{5!6!}}
\\
\\=\frac{1}{462}

What is the measure of angle 3, in degrees, in the figure shown?
yanalaym [24]

Answer:

38 degrees.

Step-by-step explanation:

There are 180 degrees in a triangle, so

m<1 = 180 - (43 + 74)

=  180 - 117

= 63 degrees.

m < 2 = m < 1   ( opposite angles) so

m < 2 = 63 degrees.

Finally, m < 3 = 180 - (63 + 79)

== 180 -  142

= 38 degrees.
