Answer:6.6 y
Step-by-step explanation:
The answers are in bold
The shown relative frequencies are 0.18, 0.19, and 0.21, which is pretty close to 0.19 - 0.20. From there you can tell that they are reasonably close to equal.
That means that the probailities are close to uniform and => <span>A uniform propabililty model IS a good model to represent probabilities related to the numbers generated by Claudia's calculator.
Therefore, the theoretical probability that any one number is chosen is likely 0.2.

30% of 70 is simply 0.3 * 70, which equals to 21
The 5 number that would round to 360 are 359,358,357,356, and 355 would all round up to 360 and 361,362,363,364 would all round down to 360
Answer:
10
Step-by-step explanation:
height = 2(Base) + 4
h = 2b + 4
Area of Triangle
A= bh/2
15 = b (2b) +4) / 2 multiply both sides by 2 and distribute the b
30 = 2
+ 4b Divide everything by 2
15 = + 2b Subtract 15 from both sides
+ 2b -15 = 0 Look a quadratic. Factor or use quadratic formula
b = 3 or b = -5 Measurements of length can't be negative. So its 3
h = 2(3) + 4 Substitute 3 in to find height
h = 10
