You have to look up in your Z score table.

P( 0.6≤ z≤ 2012) is the probability or area (of the bell shaped curve) between the value of      z = 2.212 & z = 0.6.

To that end for z₁ = 2.12 you find an area = 0.9830  and
                   for z₂ = 0.6 you find an area = 0.7257

Subtract those values  z₁ - z₂ = 0.9830 - 0.7257 = 0.2573

and P( 0.6≤ z≤ 2012) = 0.2573 (0r 25.73%)

The height of a triangle is 7 ft more than its base. If the area of the triangle is 30 ft2, what is the length of the base?
SSSSS [86.1K]

Answer:

see below

Step-by-step explanation:  5 27  7  16

area = 1/2 bh

height of a triangle is 7 ft more than its base

base = b

height = b + 7

area = 30

area = 1/2 b(h)

30 = 1/2 b(b + 7)

30 = 0.5(b²+ 7b)

30 = 1/2 b²+ 3.5b           solve for b

1/2 b²+ 3.5b = 30        

1/2 b²+ 3.5b - 30 = 0        

b²+ 7b - 60 = 0            factor

   (b +12)(b - 5) = 0    when b = -12 or 5     base length can't be negative

b = base = 5

area = 1/2 bh     1/2×2(9)     = 9

area = 1/2 bh     1/2×5(12)     = 60

area = 1/2 bh     1/2×9(16)     = 56

area = 1/2 bh     1/2×12(19)     = 114
