Is 3pi/2pi a rational number or an irrational number? Explain your reasoning

Mathematics
1 answer:
Vadim26 [7]2 years ago
7 0

Answer:

It is rational

Step-by-step explanation:

The pi terms cancel out when you divide. This is due to the rule x/x = 1 where x is any number you want except x cannot be zero. So replace x with pi and we have pi/pi = 1

Therefore,

(3pi)/(2pi) = (3/2)*(pi/pi)

(3pi)/(2pi) = (3/2)*1 .... use the rule mentioned above

(3pi)/(2pi) = 3/2

we get a fraction or a ratio of two whole numbers, so this proves that the given expression is rational.

ivolga24 [154]

Answer:

the answer is 3 feet

Step-by-step explanation:

We can use the volume formula, V =1/2 bhl to find the height of the tent

the volume is 36^{3}. The base is 4 and the length is 6 feet

​36=1/2 ⋅4⋅h⋅6

36=12h

3=h

The height of <em>the tent is 3 feet.</em>

(c) Use a calculator to verify that Σ(x) = 64, Σ(x2) = 1118, Σ(y) = 628, Σ(y2) = 87,982, and Σ(x y) = 9,627.
amid [387]

The correlation based on the computation is 0.97.

<h3>How to compute the value?</h3>

It should be noted that the question is that we should simply calculate the correlation which is r.

The correlation will be:

= Σ(x y) / (Σ(x²) × Σ(y²)

= 9627/✓(1118 × 87982)

= 9627 ✓98363876

= 9627/9917.86

= 0.97
