Answer:

d. 13x^{\frac{5}{2}}

Step-by-step explanation:

The given expression is

\sqrt{169x^5}

We can rewrite this as

\sqrt{169}\times \sqrt{x^5}

We rewrite as a rational exponent to obtain;

(13^2)^{\frac{1}{2}}\times (x^5)^{\frac{1}{2}}

Recall that;

(a^m)^n=a^{mn}

13^{(2\times \frac{1}{2})}\times (x)^{5\times \frac{1}{2}}

13^1 (x)^{\frac{5}{2}}

The correct choice is D

13x^{\frac{5}{2}}

Answer:

D

Step-by-step explanation:

We will use the radical property  \sqrt{a*b} =\sqrt{a} \sqrt{b}  to simplify this.

The problem is  \sqrt{169*x^5}

We can simplify this as:

\sqrt{169*x^5} \\=\sqrt{169} \sqrt{x^5}

Now we can use the property of radicals,  \sqrt[n]{x^a} =x^{\frac{a}{n}}  , to write as:

\sqrt{169} \sqrt{x^5} \\13*x^{\frac{5}{2}}

D is right answer.

In an inductive generalization, in order to achieve an error margin of plus or minus 3 percentage points at a confidence level o
ANTONII [103]
Let n =  required random sample size.

Assume that the population standard deviation is known as σ.
Let m =  sample mean.
At the 95% confidence level, the expected range is
(m - k(σ/√n), m + k(σ/√n))
where k = 1.96.

Therefore the error margin is 1.96(σ/√n).
Because the error margin is specified as 3% or 0.03, therefore
(1.96σ)/√n = 0.03
√n = (1.96σ)/0.03
n = 128.05σ²

This means that the sample size is about 128 times the population variance.

Answer:
Smallest sample size = 128.05σ², where σ = population standard deviation.

Determine the unknown side lengths’ to the nearest tenth. for the first question and also please help with question 6
Levart [38]

Answer:

z =15cm and

y=9.0cm

Step-by-step explanation:

Use sine rule

12/ sin53 = z / sin 90

Z = 12 x sin 90 / sin 53

Z = 15cm

To find y the angle opposite to y will be 180-(90+53)=37º

So

15/sin 90= y/sin37

y= 15 x sin37 /sin 90

y = 9.0cm

E price of a large pizza increased from $21 to $26. what is the percent of increase in the cost of pizza? round to the nearest p
rodikova [14]
Percent increase=increase/original times 100

increase=26-21=5
original=21

so
5/21 times 100=0.23809523809523809523809523809524 times 100=23.809523809523809523809523809524
round
24%

so 24% increase
