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:
If x is an integer, then for values of x ≤ 0 would -x be positive.
General Formulas and Concepts:
<u>Math</u>
Step-by-step explanation:
We know that integers comprise of the number line from -∞ to ∞. We can have numbers like -3, -2, -1, 0, 1, 2 ,3.
If we say that x is an integer, and that -x must be positive, then that means the integer x must be negative, because a negative times a negative is a positive.
∴ x can only be negative integers, thus giving us x ≤ 0.
Answer:
Its 6.45
Step-by-step explanation:
we first need to know how much is one pane of glass so i divide
15.05÷ 7 and got $2.15
so each one pane of glass is $2.15
than i multiply 2.15 x 3 and got 6.45
So the cost is 6.45
