7 0

Answer: The mean is 4, median is 4, no mode, range is 4

Step-by-step explanation:

mode is adding all the numbers and subtracting by the total amount of whole numbers

median is putting the numbers in a line ex.( 2, 6, 4, 5, 3) and crossing out left to right until theres one number left

mode is which ever number is repeated the most

range is the biggest number subtracted by the smallest number

The shorter sides of an acute triangle are x cm and 2x cm. The longest side of the triangle is 15 cm. What is the smallest possi

Veronika [31]

The longest side in the triangle is opposite to the largest angle of this triangle. If triangle is acute, then all angles are acute. Acute angle has cosine that is positive.

Use cosine theorem to determine the cosine of the largest angle:

$15^2=x^2+(2x)^2-2\cdot x\cdot 2x\cdot \cos \alpha,$ where $\alpha$ is the largest angle.

Then

$225=x^2+4x^2-4x^2\cos \alpha,\\ \\\cos \alpha=\dfrac{225-5x^2}{-4x^2}=\dfrac{5x^2-225}{4x^2}.$

Since $\cos \alpha>0,$ then

$\dfrac{5x^2-225}{4x^2}>0\Rightarrow 5x^2-225>0.$

Divide this inequality by 5:

$x^2-45>0,\\ \\(x-3\sqrt{5})(x+3\sqrt{5})>0,\\ \\x\in (-\infty,-3\sqrt{5})\cup (3\sqrt{5},\infty).$

Note that $3\sqrt{5}\approx 6.71,$ then the smallest possible whole-number value of x is 7.

Answer: correct choice is B
