Answer:

Part a) The measure of the missing angle is 90\°

Part b) The triangle of the figure is a right triangle

Part c) The triangle of the figure is a scalene triangle

Step-by-step explanation:

we know that

The sum of the interior angles of a triangle is equal to 180\°

so

Let

x------> the missing angle

we know that

x\°+50\°+40\°=180\°

solve for x

x=180\°-90\°=90\°

The triangle of the figure is a right triangle --------> by its angles

Because the triangle has an angle measure of 90\°

The triangle of the figure is a scalene triangle --------> by its sides

Because the three angles and the three sides measures are different

The probability of winning on an arcade game is 0. 659. if you play the arcade game 30 times, what is the probability of winning
mrs_skeptik [129]

The probability of winning exactly 21 times is:-0.32

Given,

The probability of winning on an arcade game, p = 0.659

Number of times you play arcade game, n = 30

By assuming this as a normal distribution, we get

Mean=μ=30×0.659 =19.77

Standard deviation, σ = \sqrt{np(1-p)}

= \sqrt{30(0.659)(1-0.659)}

≈ 2.60

Let X be a binomial variable

Then, the z score for x = 21 will be:

z = (x - μ) / σ = \frac{21-19.77}{2.60}

≈ 0.47

Now, the probability of winning exactly 21 times

P (x ≥ z) = P (21 ≥ 0.47) = 0.32

Hence the probability of winning exactly 21 times is 0.32
