Select all the numbers that are rational.
anygoal [31]

Answers:

C, D, E

Step-by-step explanation:

A rational number is a integer. It is also a terminating or repeating decimal.

A rational number can be written as a fraction of two integers.

Answer A is not correct because it's decimal never ends. It is also not repeating. A cannot be written as a fraction.

Answer B is not correct because the square root is not a whole number, or a perfect square. The square root has a non-terminating and non-repeating decimal, just like A. B cannot be written as a fraction.

Answer C is rational because it has a terminating decimal.

D and E are integers, which also can be written as fractions.

Out of the options given, C, D, and E have rational numbers, while all others do not.

The answers are C, D, and E.

Dimas [21]

Answer:

Confidence interval @ 90% = [0.5324 < p < 0.5656]

Step-by-step explanation:

We are given the following information:

Sample size (n) = 2430

Proportion of win (p) = 0.549

Proportion of loss (q) => 1-p = 0.451

By formula of confidence interval,

CI = p ± Z(90%) * \sqrt{\frac{p*(1-p)}{n}} ,

CI = 0.549±(1.645* ((0.549*(0.451))/2430))^(0.5)

CI = [0.5324 < p < 0.5656]

At what x value does the function given below have a hole?<br><br> f(x)=x+3/x2−9
S_A_V [24]

Answer:

hole at x=-3

Step-by-step explanation:

The hole is the discontinuity that exists after the fraction reduces. (Still doesn't exist for original of course)

The discontinuities for this expression is when the bottom is 0. x^2-9=0 when x=3 or x=-3 since squaring either and then subtracting 9 would lead to 0.

So anyways we have (x+3)/(x^2-9)

= (x+3)/((x-3)(x+3))

Now this equals 1/(x-3) with a hole at x=-3 since the x+3 factor was "cancelled" from the denominator.
