3 0

<span>So we wan't to see how to determine what is the next number in the number sequence. First we have to fint the pattern: 16-4=12, 36-16=20, 64-36=28, 100-64=36, 144-100=44. We see that in the pattern the next number is incremented by 8. So the next number should be 44+8=52 and we add that to the last number of the sequence: 144+52=196 and that is the next number in the sequence.</span>

A student prepares for an exam by studying a list of 10 problems. She can solve 8 of them. For the exam, the instructor selects

Answer:

Probability to solve 7 problem will be equal to $\frac{1}{15}$

Step-by-step explanation:

It is given total number of question = 10

She can solve 8 of them from 10 questions

We have to find the probability that she can solve 7 question

Probability will be equal to ratio of favorable outcome to total sample space

Favorable outcome will be equal to $^8c_7$

Total sample space $=^{10}c_7$

So probability will be equal to $P=\frac{^8C_7}{^{10}C_7}=\frac{6}{90}=\frac{1}{15}$

So probability to solve 7 problem will be equal to $\frac{1}{15}$

Name the intersection of planes ABFE and BFCD.

Mkey [24]

Two planes intersect in a line that contain all common points of these two planes.

1. Plane named ABFE contains points A, B, F and E.

2. Plane named BFCD contains points B, F, C and D.

As you can see points B and F are common points for these two planes, then the line of intersection is BF and its notation is $\overleftrightarrow{BF}.$
