Answer:
C.
Step-by-step explanation:
Y-intercept basically means where on the graph does the line "cut" through the y-axis (the vertical line). In the graphs, there is only one line which cuts through the y-axis at -1/2, which is C. .
Answer:
x=1
Step-by-step explanation:
For this problem, we can choose to eliminate either the x values or the y values.
In this case, it would be easier to do y.
We alter the first equation by multiplying by -2 on both sides.
-4x+-6y=-16
Now, we have the equations
-4x+-6y=-16 and 5x+6y=17.
We can see that there is -6y in one equation and 6y in the other, meaning that if we add both equations together, the ys will cancel each other out because they are opposites.
So let's add the equations.
-4x-6y+5x+6y=-16+17
x=1
We know that
area of a circle=pi*r²
for r=2 km
area of a circle=pi*2²-----> 12.56 km²
if 360° (full circle) has an area of---------> 12.56 km²
45°---------------------------------> x
x=45*12.56/360-----> x=1.57 km²
the answer is
1.57 km²
Answer:
p^=368=0.2222.95%CI=(0.2222−1.960.2222(1−0.2222)36,0.2222+1.960.2222(1−0.2222)36)=95%CI=(0.2222−1.96360.2222(1−0.2222),0.2222+1.96360.2222(1−0.2222))==(0.0864,0.3580).
=(0.0864,0.3580).
