Answer:
u= -4v+9
Step-by-step explanation:
Let's solve for u.
u−5=−4(v−1)
Step 1: Add 5 to both sides.
u−5+5=−4v+4+5
u=−4v+9
Answer:
u=−4v+9

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
