Answer:
60
Step-by-step explanation:
Given that :
Total crop on corn plot = 1500
Total on soya bean plot = 3000
Total on grass plot = 500
Total plants = 5000
A Stratified sample of 200 corn plants is to be selected ;
Number of samples he takes from each plot:
Percentage of number of samples :
x% of 5000 = 200
0.01x * 5000 = 200
50x = 200
x = 200/50
x = 4%
Hence, number of plants to be selected from corn plot :
4% of 1500
0.04 * 1500
= 60

Answer:
Step-by-step explanation:
Hello There!
The shown angles are supplementary angles.
We know this because a straight line is split into two angles
A straight line creates a 180 degree angle so the sum of the two angles is 180
So we can use this equation to solve for x
180 = 3x + 12 + x
3x + x = 4x
180=4x+12
step 1 subtract 12 from each side
180-12=168
12-12 cancels out
now we have
168=4x
step 2 divide each side by 4
4x/4=x
168/4=42
we're left with x = 42
The ratio is 96:3 or 96/3 all you have to do is just divide but not solve the question. It's like writing an expression.
