It's generally known that it takes 8 minutes for light to get from the Sun to the Earth. If the speed of light is 3.0 X 10^8 m/s

and the distance from the Sun to the Earth is 9.3 X 10^7 miles, is this a true statement?

Answer:

  yes

Step-by-step explanation:

The time required at the given speed and distance is ...

  time = distance/speed

  time = (9.3×10^7 mi)(1.6×10^3 m/mi)/(3.0×10^8 m/s) ≈ 4.96×10^2 s

This time corresponds to 8 minutes and 16 seconds. To an accuracy of 1 significant digit, the statement is true.

Use the definitions for the sets given below to determine whether each statement is true or false:
ella [17]

Answer:

(a) false

(b) true

(c) true

(d) true

(e) false

(f) true

(g) false

(h) true

(i) true

Step-by-step explanation:

(a) 15 ⊂ A, since 15 is not a set, but an element, we cannot say of an element to be subset of a set. False

(b) {15} ⊂ A The subset {15} is a subset of A, since every element of {15}, that is 15, belongs to A.

15 ∈ {15} and 15 ∈ { x ∈ Z: x is an integer multiple of 3 } 15 is  an integer multiple of 3. since 15/3=5. True

(c)∅ ⊂ A

∅ is a subset of any set. True

(d) A ⊆ A

A is a subset of itself. True

(e)∅ ∈ B

∅ is not an element, it is a subset, so it does not belong to any set. False

(f)A is an infinite set.

Yes, there are infinite integers multiple of 3. True

(g)B is a finite set.

No, there are infinite integers that are perfect squares. False

(h)|E| = 3

The number of elements that belong to E are 3. True

(i)|E| = |F|

The number of elements that belong to F are 3. So is the number of elements of E. True

lara [203]

Answer:

The answer is 1/30 or 0.0333333...

Step-by-step explanation:

The way to find experimental probability is by comparing the number of times the event occurs to the total number of trials. In this question, there has only been one arrangement that consists of ballooons that are all the same color. This means that 1 (the number of times the event occurred)/ 30 (total number of trials) is the answer. I hope you have a great day!!
