Answer:

D produces a rational number

Step-by-step explanation:

Given: A rational number 0.53

To find : which number produces a rational number when added to 0.53

Solution : Now, we add each number one by one

Sum of any rational number with irrational number is always a irrational number

A. \pi irrational number

\pi+0.53 =3.671393....= irrational number

B. \sqrt{5} irrational number

\sqrt{5}+0.53=2.766...... = irrational number

C. 0.2645751311...... irrational number

0.2645751311......+0.53 =irrational number

D. 5/7 rational number

5/7+0.53=0.71428571428571+0.53 =1.2442857142857142857142857...= rational number  

as repeating numbers are also a rational number

Therefore, A,B,C are irrational number

and D is a rational number

All you have to do is graph whatever those #'s are, so whatever numbers are top are the number that are on the bottom of the graph, and whatever #'s are on top are the numbers going up on the graph.

Which expression is equivalent to StartRoot StartFraction 25 x Superscript 9 Baseline y Superscript 3 Baseline Over 64 x Supersc
MAVERICK [17]

Answer:

\displaystyle \frac{5x}{8y^{4}}\sqrt{x}

Step-by-step explanation:

<u>Simplfy in Algebra </u>

We have the following expression

\displaystyle E=\sqrt{\frac{25x^9y^3}{64x^6y^{11}}}

Simplifying like factors in the denominator and numerator

\displaystyle E=\sqrt{\frac{25x^3}{64y^{8}}}

All the factors are perfect squares except x^3, thus we rewrite:

\displaystyle E=\sqrt{\frac{25xx^2}{64y^{8}}}

Taking the square root of all the perfect square factors:

\boxed{\displaystyle E=\frac{5x}{8y^{4}}\sqrt{x}}

Solve x2 – 12x + 59 = 0 for x.
mr_godi [17]
59 is a tough bird to deal with; its only factors are 1 and 59.

Thus, forget about factoring.  Instead, use the quadratic formula, or solve the equation by completing the square.

Please note:  x2 is ambiguous.  Please write x^2 to indicate "the square of 2."

Here you have 1x^2 - 12x + 59 = 0, for which a=1, b=-12 and c=59.

Use the quadratic formula:  x=[-b plus or minus sqrt(b^2-4ac)] / (2a)

to find the two roots.  Notice that the "discriminant" b^2 - 4ac will be negative, meaning that your two roots will be "complex."

You measure 27 watermelons' weights, and find they have a mean weight of 71 ounces. Assume the population standard deviation is
velikii [3]

Answer:

(69.94, 72.06)

Step-by-step explanation:

Confidence Interval formula = Mean ± z × Standard deviation/√n

Mean = 71 ounces

Standard deviation = 2.8 ounces

z score = 95% confidence interval = 1.96

Confidence Interval = 71 ± 1.96 × 2.8/√27

= 71 ± 1.96 × 0.5388602512

= 71 ± 1.0561660924

71 - 1.0561660924

= 69.943833908 ounces

Approximately = 69.94 ounces

71 + 1.0561660924

= 72.0561660924 ounces

Approximately = 72.06 ounces

95% Confidence Interval = (69.94, 72.06).
