A group consisting of 6 people is to be selected from eight parents and four teachers.
zvonat [6]

Answer:

9/32 or 0.28125

Step-by-step explanation:

8 parents and 4 teachers

There are 12 possible outcomes.

probability = # of favorable outcomes / # of possible outcomes

Let's do the teachers first.

There are 4 teachers, and we are finding the probability for 3 of them being picked.

Therefore,

P = 3/4

Now let's do the parents.

There are 8 parents, and we want 3.

Therefore,

P = 3/8

Now, we do  \frac{3}{4} *\frac{3}{8} = \frac{9}{32}

Therefore, the chance of 3 teachers and 3 parents being picked out of 4 teachers and 8 parents is 9/32, or in decimal form 0.28125.

Hope this helped!

Not sure how to answer question 4
drek231 [11]

Answer:

<em>Option D is correct</em>

Step-by-step explanation:

Applying the cosine theorem for triangle ABC, you would have:

cos (angle BAC) = (BA^2 + CA^2 - BC^2)/(2*BA*CA)

                           = (10^2 + 18^2 - 20^2)/(2*10*18)

                           = 24/360

=> angle BAC = ~86 deg

Hope this helps!

What would the second point be with point (-2,-5) to get a line with the slope of -1
choli [55]

Answer:

A second point would be (-1, -6)

Step-by-step explanation:

Because the slope is -1, we know that for every number that x increases, we change y the amount of the slope. So, if we increase x by 1, we change y by -1.

x value

-2 + 1 = -1

y value

-5 - 1 = -6
