Answer:

The probability of the number of Protestants that were calm for 2 out of 3 days is 0.061.

Step-by-step explanation:

Represent the provided data as follows:

Compute the probability of the number of Protestants that were calm for 2 out of 3 days as follows:

P (Calm\ for\ 2\ days\ |\ Protestants) = \frac{n (Protestants\ who\ were\ calm\ for\ 2\ days}{n (Protestants}

The number of Protestants surveyed is, <em>n</em> (Protestants) = 99.

The number of Protestants who were calm for 2 days,

<em>n</em> (Protestants who were calm for 2 days) = 6

The required probability is:

P (Calm\ for\ 2\ days\ |\ Protestants) = \frac{n (Protestants\ who\ were\ calm\ for\ 2\ days}{n (Protestants}\\=\frac{6}{99}\\ =0.060606\\\approx0.061

Thus, the probability of the number of Protestants that were calm for 2 out of 3 days is 0.061.

Find m <br> we learned this last week and I forgot, please help!

Answer:

x=8

Step-by-step explanation:

I think you mean find x, not m.

since angle DEG and angle GEF are a linear pair, they equal 180º.

18x-9 + 4x+13 = 180

22x + 4 = 180

subtract 4 from each side

22x = 176

divide each side by 22

x=8
