Answer:

Explanation:
Equation: y = mx + b [where "m" is slope, "b" is y-intercept]
The y-intercept (b) is -4

Here take two points: (0, -4), (5, -5)


It would be 4/11 chance bc if you you think about it, it would 7/11 of it being a sports channel which remains 4/11 of it being any of the other

Answer:
49cm^2
Step-by-step explanation:
The perimeter is just a continuous line which forms the boundaries of a geometric figure.

Answer:
Matt ;
Used diameter of the ball instead of Radius
Step-by-step explanation:
The volume of a sphere is given as :
4/3πr³
Radius, r = diameter / 2
Given that, the diameter = 15 cm ; The Radius = 15 / 2 = 7.5 cm
Matt made an error in his calculation by failing to covert the value of the diameter given to Radius.
By dividing the diameter by 2 = 15 / 2 = 7.5, we obtain the Radius, which is what Billy did in her own calculation.
