Step-by-step explanation:

$\sin(20) = 3 \div x$

Multiply both sides with x :

$x \times \sin(20) = 3$

And divide both sides with sin(20) :

$x = 3 \div \sin(20) = 8.771$

Which gives us x=8,771

A car is designed to last an average of 12 years with a standard deviation of 0.8 years. What is the probability that a car will

Scorpion4ik [409]

Due to the common probability formula I can solve that task. Refering to the task you gave, we have all the information we need. We solve it like that: $\frac{10-12}{0.8} = -2.5; Probability(-2.5)=.0.00621; Probability = 0.621%$
So the answer is the first option 0.621%
