The dot plots show rainfall totals for several spring storms in highland areas and lowland areas. What is the median rainfall fo
tresset_1 [31]

Answer:

Median highland = 16 mm

Median lowland = 16 mm

Step-by-step explanation:

For the highland area :

The sample size, n = 44

Obtain the median value using :

1/2 * (n + 1)th term

1/2 * (44 +1) th term

1/2 * 45 = 22.5th term.

(22nd + 23rd) term / 2

(16 + 16) / 2 = 16 mm

For the lowland area :

1/2 * (n + 1)th term

1/2 * (44 +1) th term

1/2 * 45 = 22.5th term.

(22nd + 23rd) term / 2

(12 + 12) / 2 = 12 mm

Simplify x^1/3(x^1/2+2x^2)
Marizza181 [45]

Answer:

x^{5/6 } + 2\cdot x^{7/3}

Step-by-step explanation:

Let be x^{1/3}\cdot (x^{1/2} + 2\cdot x^{2}), which can be simplified solely by algebraic means. We proceed to describe all the steps needed for simplification:

1) x^{1/3}\cdot (x^{1/2} + 2\cdot x^{2})  Given.

2) x^{1/3}\cdot x^{1/2} + 2\cdot (x^{1/3}\cdot x^{2}) Distributive and associative properties.

3) x^{5/6 } + 2\cdot x^{7/3} a^{m}\cdot a^{n} = a^{m+n}/Result

Given: ΔWXY is isosceles with legs WX and WY; ΔWVZ is isosceles with legs WV and WZ. Prove: ΔWXY ~ ΔWVZ
Alex777 [14]

Answer:

By AA

ΔWXY ~ΔWVZ

Step-by-step explanation:

Here WXY is an isosceles triangle with legs WX & WY

So WX = WY

Hence ∠X = ∠Y

So ∠2= ∠3.

Now by angle sum property

∠1 + ∠2+∠3 = 180°

∠1+∠2+∠2=180°

2∠2 = 180° - ∠1     .......(1)

In triangle WVZ

WV = WZ

So ∠V = ∠Z

∠4 = ∠5

Once again by angle sum property

∠1 + ∠4 + ∠5=180°

∠1 + ∠4 + ∠4 = 180°

2∠4 = 180° - ∠1       ...(2)

From (1) & (2)

2∠2 = 2∠4

∠2=∠4

Now ∠W is common to both triangles

Hence by AA

ΔWXY ~ΔWVZ

90% of a number is x . What is 100% of the number? Assume x>0
mariarad [96]

Step-by-step explanation:

Let the required number be n

\therefore \:  \frac{90}{100}  \times n = x \\  \\ \therefore \:  \frac{9}{10}   \\  \\  \therefore \:n = \frac{10}{9} x \\  \\  \therefore 100\% \: of\:n = \frac{10}{9} x \times 100\% \\  \\  = \frac{10}{9} x \times \frac{100}{100}  \\  \\  =  \frac{10}{9} x  \\

NOTE: A number is always 100% in itself.
