Medida do angulo central = medida do arco interceptado
arco = 25º e ângulo central = 25º
Answer:
a) This probability as empirical Probability.
b) This probability is not accurate because this experiment must be repeated a large number of times for empirical probabilities should be accurate.
Step-by-step explanation:
On 6 occasions, of which three times the train was late. that means 3 times the train is on time.
Empirical probability = Number of outcomes satisfying event / No.of trails
= 3/6 = 0.5.
a) This probability as empirical Probability.
b) This probability is not accurate because this experiment should be repeated a large number of times for empirical probabilities should be accurate.
The volume of a prism = area of the base * height
substitute:
640 = A * 8
base area=80 sq ft<span />
Answer:
-2
Step-by-step explanation:
To find the slope of a line, you need to find the 
between two points. I will be using the points (-3, 2) and (-1, -2).
= 
= 
= 
= -2
X=cost of large snack
Y=cost of small snack
X+Y=60
5X+3Y=220
To solve for y, solve x+y=60 for x. Subtract y from both sides so you're left with x=-y+60. You now plug in -y+60 for x in the second equation.
5(-y+60)+3y=220
-5y+300+3y=220
-2y+300=220
-2y=-80
Y=40
40 small snack packs is the final answer
