Using the given equation:

P(A or B) = P(A) + P(B) - P(A and B)

P(A or B) = 1/6 + 5/12 - ( 1/6 * 5/12)

P(A or B) = 7/12 - 5/72

P(A or B) = 37/72

An engineer estimated the weight of a steel beam to be 600 pounds. The actual weight of the beam was 639 pounds. Find the absolu
ser-zykov [4K]

Answer:

Absolute: 39 pounds

Relative: 6.5%

Step-by-step explanation:

To find the absolute difference, we simply have to see by how much pounds the estimation was off.

The real measure was 639 pounds, the estimated weight was 600.

D = 639 - 600 = 39 pounds.

For the percent of error, we divide the absolute difference (39) by the real value (639) and we'll get the % of error.  So,

%D = 39 / 600 = 0.0610, so 6.1%

We don't need to round it to the nearest tenth, since it's already to that precision level.

mash [69]

Step-by-step explanation:

P(heads) = ½, and P(tails) = ½

a) P(5 heads) = (½)⁵ = ¹/₃₂

b) P(5 tails) = (½)⁵ = ¹/₃₂

c) P(at least 1 head) = 1 − P(all tails) = ³¹/₃₂

G(n) = 4n+1<br> h(n)= -2n+3<br> Find (g+h)(n)
Mice21 [21]

Answer:

14 - 4n

Step-by-step explanation:

g = 4n+1/n

n = 1/g−4

---------------------------------------

h = −2n+3/n

n = 3/h+2

---------------------------------------

g(- n + 3) = 4(- n + 3) + 2 = - 4n + 12 + 2 = 14 - 4n

alexandr1967 [171]

Answer:

x < - 4

Step-by-step explanation:

Given

2x - 2 > 4x + 6 ( subtract 2x from both sides )

- 2 > 2x + 6 ( subtract 6 from both sides )

- 8 > 2x ( divide both sides by 2 )

- 4 > x , thus

x < - 4
