<h3>How to draw the perpendicular at a point c on line ab such the ac = 3.5 cm?</h3>The given parameters are:
Length of segment AB = 7 cm
Also, we have:
Point C is located on line segment AB
This means that:
Length of segment AC = Length of segment BC = 3.5 cm
When represented on a line segment, we have:
A C B

Answer:
Option b
Step-by-step explanation:
Given that Mrs. Gomes found that 40% of students at her high school take chemistry
since each student is independent of the other, we can say
X no of students who take chemistry is binomial with p = constant proba = 0.40
n = no of trials = no of students surveyed =12
Required probability = prob atmost 4 students take chemistry
=
Substituting we get the cumulative probability
as
0.4382
round off to 0.438
Option b is correct answer
Answer:
Total number of people = 13
A:
Number of ways to choose 10 players to take the field = 13C10
=
= 286
B:
This is given as: 13P10
= =
= 1037836800
C:
This is given as:
(3C1 x 10C9) + (3C2 x 10C8) + (3C3 x 10C7)
Solving this we get the answer as = 285
