Answer:
48 students in the class
Step-by-step explanation:
The ratio of girls to boys is 3 : 5 = 3x : 5x ( x is a multiplier ) , then
5x = 3x + 12 ( 12 more boys than girls )
Subtract 3x from both sides )
2x = 12 ( divide both sides by 2 )
x = 6
Then
number of girls = 3x = 3 × 6 = 18
number of boys = 5x = 5 × 6 = 30
total students in class = 18 + 30 = 48
Answer:
t > -7/4
Step-by-step explanation:
Step 1: Write out inequality
14 - (9t - 2) < -t + 30
Step 2: Distribute
14 - 9t + 2 < -t + 30
Step 3: Combine like terms
-9t + 16 < -t + 30
Step 4: Add 9t to both sides
16 < 8t + 30
Step 5: Subtract 30 on both sides
-14 < 8t
Step 6: Divide both sides by 8
-7/4 < t
Step 7: Rewrite
t > -7/4
Answer:
Negative
Step-by-step explanation:
From the scatter plot displayed, we could clearly observe the direction of the trend line as it produces a negative slope. For high values of y, the values of x are low and similarly, high values of x have low y values. Therefore, this kind of relationship between the two variables is considered negative.
Answer:
2
Step-by-step explanation:
68+48=116
116÷16=7.24 (wrong)
116÷12=9.7 (wrong)
116÷4=29 (lowest even)
116÷2=58 (highest even)
