Find the area of the shaded sector of the circle. Leave in terms of pi.
qaws [65]

Answer:

a=10.88\pi

Step-by-step explanation:

using the formula below, the central angle is 20° (bc 360-180-160=20)

radius is 14 (28/2=14)

\frac{20}{360} =\frac{a}{\pi r^2} \\ \frac{1}{18} =\frac{a}{\pi 14^2}

\frac{1}{18} =\frac{a}{196\pi}

a=\frac{1*196\pi}{18} \\a=1*10.88\pi\\a=10.88\pi

A couple has 2 children. what is the probability that both are girls if the older of the two is a girl?
12345 [234]
Assuming that the probability of boys and girls is equal (in reality slightly more boys than girls are born), the probability is 1/2, simply because the older girl's gender is given and therefore not a part of the probability.

This question comes from the 'boy or girl paradox', a.k.a. the Mrs Smith Problem.

Complete the set of ordered pairs for the relation.
Nonamiya [84]

The set of ordered pairs are (-2,18),(-1,20),(0,22),(1,24),(2,26)

Step-by-step explanation:

Given that the relation \{(x, y): y=2(x+11) \text { and } x \in(-2,-1,0,1,2)\}

To find the set of ordered pairs, let us substitute the value for x in the relation y=2(x+11)

For x=-2,

\begin{aligned}y &=2(-2+11) \\&=2(9) \\y &=18\end{aligned}

The ordered pair is (-2,18)

For x=-1,

\begin{aligned}y &=2(-1+11) \\&=2(10) \\y &=20\end{aligned}

The ordered pair is (-1,20)

For x=0,

\begin{aligned}y &=2(0+11) \\&=2(11) \\y &=22\end{aligned}

The ordered pair is (0,22)

For x=1,

\begin{aligned}y &=2(1+11) \\&=2(12) \\y &=24\end{aligned}

The ordered pair is (1,24)

For x=2,

\begin{aligned}y &=2(2+11) \\&=2(13) \\y &=26\end{aligned}

The ordered pair is (2,26)

Thus, the set of ordered pairs is (-2,18),(-1,20),(0,22),(1,24),(2,26)
