Answer:
<u>1/ 130 is the probability that they are the 4 oldest people in the group. </u>
Step-by-step explanation:
In the question, we are given; group of 11 people, 4 are selected randomly, find probability they are the 4 oldest people from the group
P(O)= <em>favorable number of outcomes / total number of outcomes </em>
<h3>= 1 / 11C4</h3>
= 11! / (11-4)! 4!
= 7! *4! / 11!
=1/ 130
<em>Therefore, 1 / 130 is the probability that they are the 4 oldest people in the group. </em>

Answer:
B
Step-by-step explanation:
Since x is 2 wherever you see x put 2
solve x3 + x7+ 2
=(2)3 + (2)7 + 2
= you do the number outside the bracket multiplied by the number inside the bracket
like this
=(2 × 3) + (2 × 7) + 2
= 6+ 14 + 2
= 22

Answer:
<h3>YES</h3>
Step-by-step explanation:
Given the position of the particle expressed using the expression;
x(t)= 5t^3 - 9t^2 + 7 where;
x moves along the positive x-axis
when t = 1
x(1) = 5(1)^3 - 9(1)^2 + 7
x(1) = 5 - 9 + 7
x(1) = -4 + 7
x(1) = 3
<em>Since the position of the particle is positive at t = 1, hence the particle is moving towards the right at time t = 1</em>
