Answer:
y < -1/2
Step-by-step explanation:
Step 1 :
8
Simplify —
3
Equation at the end of step 1 :
4 8
— - (0 - (— • y)) < 0
3 3
Step 2 :
4
Simplify —
3
Equation at the end of step 2 :
4 -8y
— - ——— < 0
3 3
Step 3 :
Adding fractions which have a common denominator :
3.1 Adding fractions which have a common denominator
Combine the numerators together, put the sum or difference over the common denominator then reduce to lowest terms if possible:
4 - (-8y) 8y + 4
————————— = ——————
3 3
Step 4 :
Pulling out like terms :
4.1 Pull out like factors :
8y + 4 = 4 • (2y + 1)
Equation at the end of step 4 :
4 • (2y + 1)
———————————— < 0
3
Step 5 :
5.1 Multiply both sides by 3
5.2 Divide both sides by 4
5.3 Divide both sides by 2
y+(1/2) < 0
Solve Basic Inequality :
5.4 Subtract 1/2 from both sides
y < -1/2

I'll just do a relative frequency for the whole table:
Enjoyed Did not Enjoy Total
Males 47 13 60
Females 53 3 56
Total 100 16 116
Enjoyed Did not Enjoy Total
Males 47/116 = 0.41 13/116 = 0.11 60/116 = 0.52
Females 53/116 = 0.45 3/116 = 0.03 56/116 = 0.48
Total 100/116 =0.86 16/116 = 0.14 116/116 = 1.00
<span>
I'm not sure where a and b should be but based on the table: it can a = 41% ; b = 3% or a = 47% or b = 3%</span>
Answer:
It will take 2.5 hours
Step-by-step explanation:
Speed = 10 km/hr
Distance = 25 km
We can use the formula
d=rt
Where d = distance, r =rate (speed) and t is time
25 = 10*t
Divide each side by 10
25/10 = 10t/10
2.5 = t
It will take 2.5 hours
