Can you ever use a calculator to determine if a number is rational or irrational

By definition and according to Google:

"Irrational numbers<span> cannot be represented as terminating or repeating decimals."

So the answer to your question would have to be 'no' as calculators were designed to give us approximate answers when dealing with irrational numbers.

It would be hard to guess whether a large number produced by a calculator is irrational or not given that fact that many rational numbers can be incredibly long.

Eight trials are simulated. The results are shown in the table.
bezimeni [28]

Answer:

2.897

Step-by-step explanation:

Let us find the mean and variance for the sample first.

105 104 110 112

114 106 108 109

Mean = sum/8 = 108.5

Variance = 12

Std dev = sq rt of variance = 3.464

Std error = std dev/ sq rt n

since n =8, we get std error = 1.225

Since sample size is small, df =8-1 =7

For 95% confidence intervals, t critical value for two tailed=2.365

Margin of error = std error x t critical = 1.225(2.365)

=2.897

Find the perimeter of the triangle.<br> 23.<br> 7 in.<br> (x + 4) in.<br> (4x + 1) in.
Ganezh [65]

Answer:

17 in.

Step-by-step explanation:

There are two same angles shown, so two sides are equal. We can form an equation x+4=4x+1. Solution is x=1, then both unknown sides are 5 in. long. Given all side lengths we add them 7+5+5+15 getting the perimeter.

Determine the maximum number of zeros of the polynomial function -8x^4-x^2+2
kap26 [50]
To find that one, just look at the highest exponent.  In the given equation that would be 4, so there can be at most 4 zeros in this function.
