30 students in a class ; 16 are boys
Girls to boys : to find the amount of girls, simply subtract the student total with the boy total.
30 - 16 = 14
Therefore there are 14 girls in the class
So, our ratio should be ~ 14 : 16
Girls to all students :
Girls is 14 students is 30
Therefore the ratio to girls to all students is ~ 14 : 30
Boys to girls : Simply get the boys amount to the other side of the girls amount
Therefore the ratio of boys to girls is ~ 16 : 14
Boys to all students : Get the amount of boys and the amount of all students to the opposite side of each other.
Therefore the ratio of boys to all students is ~ 16 : 30

6/9 is the slope
Step-by-step explanation:
Answer:
(-2, 1)
Step-by-step explanation:
You have written the function with no parentheses, so the minus sign is applied after the square:
f(-2) = -(-2)^2 +5 = -4 +5 = 1
The point is (-2, 1).
Answer and Explanation:
Number of classes = 8
Highest value =2300
Lowest value = 1250
Class width= highest value – lowest value / number of classes
= 2300 – 1250/8
= 131.25 = 132
So, we can write class as 1250+132=1382
Class frequency
1250-1382 2
1382-1514 3
1514-1646 6
1646-1778 2
1778-1910 3
1910-2042 2
2042-2174 1

Answer: C. f(x)=1.5x
Step-by-step explanation:
Here's the complete question:
In a direct variation equation f(x) = 6 when x = 4. what is the direct variation equation
A-f(x)=6x
B-f(x)=4x
C-f(x)=1.5x
D-f(x)=0.67x
The direct variation equation will be:
6 = kx
When x = 4, this will be:
6 = 4k
k = 6/4
k = 1.5
Therefore, the direct variation equation is: f(x)=1.5x
