Likurg_2 [28]

Years for one serious accident is 10 year

Given:

Probability of having a serious accident = 10% every year

P(serious accident) = 0.1

Number of years = n

Computation:

Years for one serious accident = 1 / Probability of having a serious accident

Years for one serious accident = 1 / P(serious accident)

Years for one serious accident = 1 / 0.1

Years for one serious accident = 10 year

8. A cable car travels 2236 m to climb a mountain that is 1000 m high. It then travels 1414 m to descend 1000 m on the other sid

frutty [35]

Answer:

3000 m

Step-by-step explanation:

Using Pythagoras theorem

$2236^2=1000^2+|AB|^2\\|AB|^2=2236^2-1000^2\\|AB|^2=3999696\\|AB|=\sqrt{3999696} \\=1999.9$

Similarly

$1414^2=1000^2+|BC|^2\\|BC|^2=1414^2-1000^2\\|BC|^2=999696\\|BC|=\sqrt{999696} \\=999.7m$

Length of the Tunnel = |AB|+|BC|

=1999.9+999.7

=2999.6

=3000 m

Given that angle a = 72° and angle b = 37°, work out x.

Sedbober [7]

Answer:

x is 71

Step-by-step explanation:

X + 72 + 37 = 180 ( Sum of angles in a triangle)

X = 180 - 72 - 37

X = 71
