Step-by-step explanation:
7√3-4√6+√48-√54
=7√3-4√6-√(16×3)-√(9×6)
=7√3-4√6-4√3-3√6
=3√3-7√6
Answer:
0.9056
Step-by-step explanation:
We are given;
Number of students enrolled in both General Chemistry and Calculus I = 540 students
Number of students who received an A in general chemistry = 51 students
Number of students who received an A in calculus = 59 students
Number of students who received an A in both general chemistry and calculus = 30 students
Now, we want to find the probability that a randomly chosen student did not receive an A in general chemistry.
So, first of all let's calculate number of students who didn't receive an A in chemistry.
So,
No without A in chemistry = 540 - 51 = 489 students
So, probability that a randomly chosen student did not receive an A in general chemistry = 489/540 = 0.9056
Answer:
30.0%
Step-by-step explanation:
0.63×0.23=0.1449≈14.5% approx 14.5%
Therefore, 14.5% of all students at the school are girls who wear contacts.
Let's repeat this for boys by multiplying the percent of boys at the school by the percent of boys that wears contacts.
0.37×0.42=0.1554≈15.5% approx 15.5%
Therefore, 15.5% of all students at the school are boys who wear contacts.
0.145+0.155=0.3=30.0%
30.0% of all the students wear contacts.
