Answer:
Stratified sampling technique(A)
Step-by-step explanation:
From the question, the population of an high school from which selection was made equals 461 sophomores, 328 juniors and 558 seniors.
35 sophomores, 69 juniors and 24 seniors are randomly selected. The technique used in selecting is Stratified sampling technique. This is because stratified sampling involves dividing the entire population into stratas and then selects a final sample randomly from the different strata. This means that a smaller part of the entire population is used as a sample in drawing conclusions for the entire population.
Answer:
Soup B
Step-by-step explanation:
Given :
Soup A:
Sodium(mg) 720
Ounces 6 1
Soup B :
Sodium(mg) 600
Ounces 4 1
To Obtian the amount of sodium per ounce in each of soup A and B
Soup A :
Sodium per ounce = 720 mg / 61 = 11.803 mg / ounce
Soup B:
Sodium per ounce = 600 mg / 41 = 14.634mg / ounce

Temperature is the abiotic factor that is changing the ecosystem. Both the top layer temperature and the overall temperature of the lake are increasing. The warmer temperatures have delayed the yearly springtime mixing of warm and cold water in the lake.
Answer:
x = -12
Step-by-step explanation:
-2.5(x-4)=-3x+4
Distribute
-2.5x +10 = -3x +4
Add 3x to each side
-2.5x+10 +3x = -3x+4+3x
.5x +10 = 4
Subtract 10 from each side
.5x+10-10=4-10
.5x = -6
Divide by .5
.5x/.5 = -6/.5
x = -12
Well, you have the radius and the center already. So all you have to do is graph the center point, then count from that center point out 5 units, then draw the circle.
