Answer:

Minimum < Q1 < Median < Q3< Maximum

Step-by-step explanation:

Given

Minimum, Median, Maximum, Q3 and Q1

<em>See attachment for complete question</em>

Required

Order from least to greatest

In a dataset, the range is:

$Range = Maximum - Minimum$

This implies that, the minimum is the least and the maximum is the highest of the dataset

So, we have:

Minimum < < < < Maximum

The median is the middle item; So, the above becomes

Minimum < < Median < < Maximum

In a dataset, the IQR is:

$IQR = Q_3 - Q_1$

This implies that:

$Q_3 > Q_1$

So, we have:

Minimum < Q1 < Median < Q3< Maximum

What is the perimeter of this shape?

Korvikt [17]

Answer:

59.4 km

Step-by-step explanation:

First you need to find the circumference of the circle. 20*3.14=62.8. Then, you divide this by two, because there is only half of a circle, to get 31.4.

Then you can just add 16 + 12 + 31.4 to get 59.4.

____ x 2 = ____+4 =___

number of crocodiles____×2=___+4=__

( multiply symbol is x )

example : 5 crocodiles x 2 = 10 crocodiles + 4 = 14 turtles

If the interval (a, ∞) describes all values of x for which the graph of 4/x^2-6x+9 is decreasing, what is the value of a?

harkovskaia [24]

Answer:

a = - 1.1

Step-by-step explanation:

Condition for a single variable function f(x) to be decreasing is f'(x) < 0.

So, in our case, $f(x) = \frac{4}{x^{2}} - 6x + 9$ .

Then, differentiating with respect to x on both sides we get,

$f'(x) = 4(- 2)\frac{1}{x^{3}} - 6 < 0$

⇒ $- \frac{8}{x^{3}} - 6 < 0$

⇒ $\frac{8}{x^{3}} + 6 > 0$

{Dividing both sides with - 1 and hence the inequality sign changes}

⇒ $\frac{8}{x^{3}} > - 6$

⇒ 8 > - 6x³ {Multiplying both sides with x³}

⇒ 6x³ > - 8 {Interchanging the sides}

⇒ $x^{3} > - \frac{8}{6}$

⇒ x > - 1.1

Therefore, a = - 1.1. (Answer)

Which of the triangles are right triangles? Please be 100% sure about your answers. I will mark Brainliest!

Kisachek [45]

1 is wrong because the measurements do not work for the pythagorean theorem.
3 is wrong because using the pythagorean theorem with those measurements would not work.
4 is wrong because the only way that 4 would work is if the hypotenuse was 3√2 not 3√3

The correct answer is 2 because that is the only one that actually works with the pythagoran theorem.

√41^2 = 41
5^2 + 4^2 = 25 + 16 = 41
41 = 41
