Slope intercept form is y = mx + b
Pick one of the coordinates, I’ll use (-3,-4) as the example.
Coordinates are just numbers plugged in for (x,y).
This means -3 would be your x and -4 would be your y.
So plug these numbers into the equation and you get -4 = m(-3) + b.
M is slope and to find slope, you need to do (y2-y1) / (x2-x1).
In other words, it would be (-3 - -4) / (4 - -3) = 1/7 which is your slope (m).
Now plug that in for m to get the b variable.
-4 = 1/7(-3) + b.
B = -3.57
Your answer is y = 1/7x -3.57
The possibilities are:
bbbb
bbbg
bbgg
bggg
This shows that there is a 1 in 4 chance of having three boys and one girl
So the answer could be 1/4 or a 25% chance
Answer:
47.2 miles per hour
Step-by-step explanation:
472 miles/ 10 hours= 47.2
Answer:
Height is 10 units
Volume is 785 cubic units
Step-by-step explanation:
We are given;
Diameter of a cylinder as 10 units
But, radius = d/2
= 5 units
Height is twice its radius,
Thus, Height = 10 units
We can get the volume;
Volume of a cylinder = pir²H
Taking pi to be 3.14
Then;
Volume = 3.14 × 5²× 10
= 785 cubic units
Thus, the volume of the cylinder is about 785 cubic units
