Answer:

A statistical question Len could ask is <u><em>"How tall is a red kangaroo?"</em></u>

Step-by-step explanation:

A statistical question is something that we can ask and test hypotheses about using collected data. There will not be a specific answer, but rather multiple answers and we can average them in a sampling distribution.

Let's examine each question:

<u>"How tall is a red kangaroo?"</u>

  • There is not a specific height for each kangaroo, so we can take the averages of many different samples and find the "true mean" in the sampling distribution. This is a good example of a statistical question because data can be collected on red kangaroos and means can be calculated.

<u>"Are there red kangaroos in Asia?"</u>

<u>"Are red kangaroos an endangered species?"</u>

<u>What is the tallest red kangaroo ever recorded?"</u>

  • These are all examples of non-statistical questions. They are "yes" or "no" questions, and we cannot take multiple samples to determine the answer. Rather, there is a single answer that we do not need to test hypotheses or perform any statistical calculations.

Simplify the expression.<br><br>x^5/x^9<br><br>a. 1/x^4<br><br>b.x^14<br><br>c. 1/x^14<br><br>d.x^4
bogdanovich [222]
Answer: B. 1/x^4
When you divide the coefficients of exponents you must subtract the exponents. In this cause it got to x^-4. You cannot leave it as a negative exponent so you must put it as the denominator in this cause to get rid of the exponent making the answer b. 1/x^4.

Select and use the most direct method to solve 2x(x + 1.5) = -1. Describe and justify the methods you used to solve the quadrati
miskamm [114]

Step-by-step explanation:

Given that,

A quadratic equation,

2x(x + 1.5) = -1

We need to solve the quadratic equation. Firstly we need to simplify the above equation to form it as ax^2+bx+c=0.

So,

2x^2+3x=-1\\\\2x^2+3x+1=0

Here, a = 2, b = 3 and c = 1

The roots of the given equation can be given by :

x=\dfrac{-b\pm \sqrt{b^2-4ac} }{2a}

Putting all the values we get :

x=\dfrac{-b\pm \sqrt{b^2+4ac} }{2a}, \dfrac{-b\pm \sqrt{b^2-4ac} }{2a}\\\\x=\dfrac{-3\pm \sqrt{3^2+4(2)(1)} }{2(2)}, \dfrac{-3\pm \sqrt{3^2-4(2)(1)} }{2(2)}\\\\x=\dfrac{-3+1}{4}, \dfrac{-3-1}{4}\\\\x=-\dfrac{1}{2}, -1

So, the roots of the given equation is -1/2 and -1.

The volume of a shipping container is 448.656 cubic inches, and it can hold 24 smaller boxes. What's the volume of each of the s
madreJ [45]

Answer:

The volume of each of the smaller boxes = 18.694  inches³

Step-by-step explanation:

The volume of Shipping container = 448.656  inches³

The shipping container hold small boxes of numbers = 24

So, The volume of each of small boxes = \frac{448.656}{24} inches³

Or, The volume of each of small boxes = 18.694  inches³

Hence The volume of each of 24 small containers is 18.694 inches³ Answer
