7:120 i think thats what its asking
P(<em>Z</em> ≥ <em>z</em>) = 1 - P(<em>Z</em> ≤ <em>z</em>) = 0.06
==> P(<em>Z</em> ≤ <em>z</em>) = 0.94
==> <em>z</em> ≈ 1.7507
Answer:
84/6=14. Each side is 14 because there are 6 sides to a hexagon.
Step-by-step explanation:
The triangle ABC is a right angled triangle , right angled at C because it is the angle subtended by the diameter
Now OA = OB = OC = 4 cm (radii)
AB = OA + OB = 8 cm
By pythagoras theorem ,
AC =4 
shade region area = area of semicircle - area of triangle
= 
- 1/2 × base × height
=1/2 × 16 
- 1/2 × 4 × 
=8 - 8
=8(
)

Step-by-step explanation:
Given
2x + 7y = 42
To find the x- intercept let y = 0 in the equation and solve for x
2x + 7(0) = 42, that is
2x = 42 ( divide both sides by 2 )
x = 21 ← x- intercept or (21, 0 )
To find the y- intercept let x = 0 in the equation and solve for y
2(0) + 7y = 42 , that is
7y = 42 ( divide both sides by 7 )
y = 6 ← y- intercept or (0, 6 )
