<span>There is a 20% (or 20/100chance) it will rain on Thursday and there is a 40% (or 40/100) chance it will rain on Friday. In order to find out the probability of it raining both days, we need to multiply these two values. (40/100)(20/100)= 800/10,000= 0.08. We move the decimal over two places to get a percent, so we get an 8% chance it will rain on both Thursday and Friday.</span>
Answer:
Step-by-step explanation:
12) looking at the right angle triangle,
x = hypotenuse
y = adjacent side
Opposite side = 4
To determine x, we would apply
the sine trigonometric ratio.
Sin θ, = opposite side/hypotenuse. Therefore,
Sin 30 = 4/x
x = 4/sin30 = 4/0.5
x = 8
To determine y, we would apply
the Cosine trigonometric ratio.
Cos θ, = adjacent side/hypotenuse. Therefore,
Cos 30 = y/8
y = 8Cos30 = 8 × 0.866
y = 6.93
14) looking at the right angle triangle,
hypotenuse = 22
y = opposite side
x = adjacent side
To determine y, we would apply
the sine trigonometric ratio.
Therefore,
Sin 45 = y/22
y = 22Sin45 = 22 × 0.7071
y = 15.6
x = y = 15.6 because the triangle is an isosceles triangle.
