Given:
m(ar LNM) = 280°
To find:
The value of y.
Solution:
Complete angle = 360°
m(ar LNM) + m(ar LM) = 360°
280° + m(ar LM) = 360°
Subtract 280° from both sides.
280° + m(ar LM) - 280° = 360° - 280°
m(ar LM) = 80°
Inscribed angle is equal to the half of the intercepted arc.
The value of y is 40 degrees.
b = -
multiply both sides by 2(b + 1) to eliminate the fraction
3 = 3× 2(b + 1)
3 = 6(b + 1) = 6b + 6 ( subtract 6 from both sides )
- 3 = 6b ( divide both sides by 6 )
b = - = -
Answer:
The standard deviation for the number of students who work full time = 8.38
Step-by-step explanation:
Given data
Sample size n = 284
No. of students work full time is P = 55 % = 0.55
No. of students who not work full time is Q = 100- 55 % = 45 % = 0.45
The standard deviation is given by
Put all the values in above equation we get
S.D. = 8.38
This is the standard deviation for the number of students who work full time.

Answer:
x = 31
Step-by-step explanation:
The sum of angles in a triangle is 180°.
98° +51° +x° = 180°
x° = 31° . . . . . . . . . . . . subtract 149°
x = 31
