4 : 5
300 : ?
Divide 300 by 4 to find out what '1 part' would count as:
300/4 = 75
Multiply this by 5
75 x 5 = 375
Add the two values together
375 + 300 = 675
There are 675 students

Step-by-step explanation:
Number of boys=300
Ratio of boys to girls=4:5
let the number of girls=y
300/y=4/5
Cross multiply
300×5=4×y
1500=4y
Divide through both sides by 4
1500/4=4y/4
374=y
Number of girls is 375
Total number of students=Number of boys+Number of girls
Total number of students=300+375
Total number of students=375

Answer:
1 + i
Step-by-step explanation:
Given that A is a 3 * 3 singular matrix
one of its eigenvalue ( λ1 ) = 1 - i
Given that the determinant of a singular matrix is = 0
therefore the second eigen value ( λ2 ) = 1 + i
1 - i + 1 + i = 0
The function and the first value stated for x are confusing.
Doing some research, I found that the problem is to evaluate the function
for x = - 1 and x 2.
The solution is:
1) For x = - 1
2) For x = 2
