Answer:

25% chance

Step-by-step explanation:

There are 3 prime numbers on a 6-sided die so that means there is a 1/2 chance you roll a prime number. In order to calculate the probability of 2 or more events you multiply their probability which would be

1/2 * 1/2 = 1/4

So the chance of rolling a prime number on both rolls is a 1/4 chance or a 25% chance

Students in Miss Moseley's fourth grade class are learning multiplication, and they demonstrate mastery by passing assessments.

Answer:
Each will have passed 17 tests and it will take 3 weeks.

Explanation: 
Let x be the number of weeks.
The number of tests Travis passes to begin with is 11.
We then add 2 tests per week, or 2x to that, giving us:
11+2x.

The number of tests Jenifer has passed to begin with is 2.
We then add 5 tests per week, or 5x to that, giving us:
2+5x.

Setting these equal, we have: 
11+2x=2+5x.

Subtract 2x from each side: 
11+2x-2x=2+5x-2x;
11=2+3x.

Subtract 2 from each side: 
11-2=2+3x-2;
9=3x.

Divide both sides by 3:
 $\frac{9}{3} = \frac{3x}{3}$ ;
3=x.

It will take 3 weeks.
In 3 weeks,
Travis will have passed:
11+2*3 = 11+6 = 17 tests.
Jenifer will have passed the same number, since she catches up with him at this point.

Is it possible for a segment to have more than one bisector? Explain your reasoning.

lord [1]

Yes.

A bisector of a line segment is a line which divides the line segment into two equal parts.
A bisector of a line can divide the line in many different ways forming different angles.
A bisector is said to be a perpendicular bisector if the angle at the intersection of the two lines is 90 degrees.
But, there are several other bisectors that are not perpendicular bisectors.

Therefore, it is possible for a segment to have more than one bisector.
