Answer:
No solution
Step-by-step explanation:
This is no solution due to the fact that the slope of both of the equation are the same. So they are parallel. If the b value is the same then it is infinitely many solutions. Due to the fact that the b value is not the same they are a set of parallel line. Parallel line do not touch or intersect ever so there for this is a no solution set.
Answer:
Trapezium:
perimeter= 232
area= 2052
Triangle:
perimeter= 221
area= 4088
Step-by-step explanation:
Since we are not given any information about the proportion, we will assume the sample proportion to be 0.50
so,
p = 0.50
The Error is 10% percentage point. This means that on either side of the population proportion the error is 5% so E = 0.05
z = 1.645 (Z value for 90% confidence interval)
The margin of error for population proportion is calculated as:
This means 271 students should be included in the sample
Answer:
rational
Step-by-step explanation:
because it has a decimal
Answer:
Graph the equations
Step-by-step explanation:
x - y = 1
3x + 2y = - 12
Rewrite equations into y=mx+b form:
y = -1 + x
y = -6 - 1.5x
Graph it!
