There are 10 students in a social studies class. three students will be selected to present their term projects today. in how many different orders can three students be selected? a. 120 b.720 c. 60 d. 1440 what is the theoretical probability of rolling a sum of 8 on one roll of two standard number cubes? a. 5/36 b.1/6 c. 1/9 d. 1/12

Step-by-step explanation:

Given that there are 10 students in a social studies class. three students will be selected to present their term projects today.

Since order does not matter,

3 students can be selected from 10 students in 10C3 ways

Option A is right

When a cube is rolled we have 36 outcomes

If total of 8 is desired, then favourable outcomes are

(2,6)(3,5)(4,4)(5,3)(6,2)

Hence theoretical probability =no of favourable outcomes/no of total outcomes

=

parallel and congruent

step-by-step explanation:

the movement of translation is linear.   these have the same translation because you are using the same rule for each point of the triangle so you will see the same slope being used to get from a point on the triangle to its image.

same slope!   you should think parallel when you see those 2 word together (well unless it's the same line but it can't be because we are coming from different points here)

congruent! because each point is being moved the same distance.

don't give

take it once

try and try and you will not
