Answer:

15.15% probability that Neil selects a bone and then a ball

Step-by-step explanation:

A probability is the number of desired outcomes divided by the number of total outcomes.

Initially, there are 3+4+5 = 12 treats. 4 of those are bones. So the probability of selecting a bone is 4/12 = 1/3.

Now suppose a bone has been selected. Now there are 11 treats, 5 of which are balls. So the probability of selecting a ball in this situation is 5/11.

What is the probability Neil selects a bone and then a ball?

p = \frac{1}{3}*\frac{5}{11} = \frac{5}{33} = 0.1515

15.15% probability that Neil selects a bone and then a ball

What is the range of the function represented by this graph? the graph of a quadratic function with a minimum value at the point
tatiyna

Answer:

see explanation

Step-by-step explanation:

The minimum is at the vertex (- 3, 1 ), that is y = 1

Since the graph is a minimum then it opens vertically up U

The range of the values of y are therefore

range [ 1, ∞ )

Find the coordinates of point X that lies along the directed line segment from Y(-8, 8) to T(-15, -13) and partitions the segmen
Nataly_w [17]

Answer:

C. (-13, -7)

Step-by-step explanation:

The location of a point O(x, y) that divides a line AB with location A(x_1,y_1) and B(x_2,y_2) in the ratio m:n is given by:

x=\frac{m}{m+n} (x_2-x_1)+x_1\\\\y=\frac{m}{m+n} (y_2-y_1)+y_1

Therefore the coordinates of point X That divides line segment from Y(-8, 8) to T(-15, -13) in the ratio 5:2 is:

x=\frac{5}{5+2} (-15-(-8))+(-8)\\\\x=\frac{5}{7} (-15+8)-8=\frac{5}{7}(-7)-8=-5-8=-13 \\\\\\y=\frac{5}{5+2} (-13-8)+8\\\\y=\frac{5}{7} (-21)+8=5(-3)+8=-15+8=-7

Therefore the coordinates of point X is at (-13, -7)

Answer: Plane AEF

Step-by-step explanation: Parallel means equal or same as. If you follow the letters BCD you can see that it sorta makes a triangle shape. So if you follow the answer choices you could see that AEF is the only one that does what BCD does if that makes sense :)

Ivahew [28]

Answer:

\boxed{0}

.

Step-by-step explanation:

3(2^3 + (4 - 2)^3 - (6 - 2)^2)

= 3(2^3 + 2^3 - 4^2)

= 3(2.2^3 - (2^2)^2)

= 3(2^4 - 2^4)

= 3(0)

= 0
