15x = 45
x = 3
10z = 45
z = 4.5
m<1 = 4y - 18
90 = 4y - 18
4y = 90 + 18
4y = 108
y = 27
Answer:
60=3/4
x=4/4
4/4÷1/4
4/4*4/1
4/1*1/1
4/1
4
3/4=12 because if 1/4 is 4 then 3/4 is 12
60=12
60÷12=5
5*4/20
60+20=80

Answer:
y = 12x+16
Step-by-step explanation:
Simplify both sides of the equation then isolate the variable.
Step 1, add 11 to both sides.
−1
/2
y+11+−11=6x+3+−11
−1
/2
y=6x−8
Step 2, divide both sides by (-1)/2.
You will be left with
y = 12x+16
Answer:
The herbicide has no impact on fish
Step-by-step explanation:
Experimental research includes to divide the concerned group 'fishes' here into 'treatment' & 'control' group, to study impact of a treatment. Hypothesis test the statistical significance of propositions. Null hypothesis signifies no impact, alternate hypothesis signifies impact.
Let averages enzyme level of treatment & control be Xt & Xc
- Null Hypothesis [H0] : Xt = Xc, or Xt - Xc = 0
- Alternate Hypothesis [H1] : Xt ≠ Xc, or Xt - Xc ≠ 0
If hypothesis test suggests that there is no significant difference between treatment & control group enzyme level, so we reject H0 & accept H1. It implies that the herbicide has no significant impact on fishes enzymes.
