Turn them into improper fractions and then flip 27/8 to its reciprocal (8/27) and then multiply.
Area of a sector: 1/2r^2 theta
Need theta
Let x be theta for now
42.25 pi = 1/2r^2x
84.5pi = r^2x
84.5pi = 169x
x = 84.5pi/169 = roughly 1.57 in radians
Radians => degrees is 1.57 * 180/pi or roughly 90.
Given that the<span> iq scores for large populations are centered at 100.
To get what percent of these 78 students have scores above 100 we conduct a normal distribution probability of the data.
P(x > 100) = P(z > (100 - 100)/sd) = P(z > 0) = 1 - P(z < 0) = 1 - 0.5 = 0.5 = 50%

Answer:
x = 6
Step-by-step explanation:
<u>Step 1: Distribute
</u>
2(3x + 2) = 2x + 28
(2 * 3x) + (2 * 2) = 2x + 28
(6x) + (4) = 2x + 28
<u>Step 2: Subtract 2x from both sides
</u>
6x + 4 - 2x = 2x + 28 - 2x
4x + 4 = 28
<u>Step 3: Subtract 4 from both sides
</u>
4x + 4 - 4 = 28 - 4
4x = 24
<u>Step 4: Divide both sides by 4
</u>
4x / 4 = 24 / 4
<em>x = 6
</em>
Answer: x = 6
