Answer:
See below.
Step-by-step explanation:
Using the right triangle altitude theorem, the correct proportions are:
AC = 20 cm
CB = 15 cm
Answer:
14√2
Step-by-step explanation:
This is a 45-45-90 triangle
Because both of the angles are the same all sides, but the hypotonouse are the same
this means that the other length is 14 too
we can use a²+b²=c² to solve
14²+14²=c²
=
392=c²
√392=c
√392=14√2
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>

According to the table, when x = 2, y = 12, and when x = 6, y = 4. We fit them into the slope formula like so:
.
The slope of the line between the two points is -2.
