Answer:
The school C shows the greatest rate of change between male and female students
Step-by-step explanation:
Let
x -----> the number of female students
y ----> the number of male students
we know that
The ratio of male students to female students is

we have
<em>School A</em>

<em>School B</em>
----> the slope of the linear equation
<em>School C</em>

so

therefore
The school C shows the greatest rate of change between male and female students
Answer:
x = 15
Step-by-step explanation:
We know that 4x° + 8x° make a straight angle of 180°.
4x° + 8x° = 180°
12x° = 180°
12x = 180
x = 180/12 = 15
Answer:
x = 21
Step-by-step explanation:
the equation is 2x + 10 = 52
2x = 42
x = 21
Answer:
12
Step-by-step explanation:
560-500=60
60/500*100=12
Answer:
9/100
Step-by-step explanation:
There are 10 marbles in the bag
There are 3 pink marbles.
P (1st marble pink) = pink marbles/ total marbles
= 3/10
We put the marble back.
There are 10 marbles in the bag
There are 3 pink marbles.
P (2nd marble pink) = pink marbles/ total marbles
= 3/10
Multiply the probabilities together
P (pink, then pink) = 3/10 * 3/10 = 9/100
