Solution:

we have been asked to find that whether the given statement is True or False.

Replacing only the minimum value in a data to a smaller number will change the median....FALSE

As we know the median is caluclated by arranging the given numbers in ascending/descending order. The we choose the middle one as a median if total number of numbers are odd. But if toal numbers of numbers are even then we take the average of the middle two and that average is the median.

So if we you are going add a number in the given set of numbers then surely the median is going to change, irrespective of the vaue of the number.

Hence the given statement is False.

Three numbers add up to 210. The second number is 10 more than the first and the third number is 3 times the first. Find the num

svp [43]

Answer:

I. First number, a = 40.

II. Second number, b = 50.

III. Third number, c = 120.

Step-by-step explanation:

Let the three numbers be a, b and c respectively.

Given the following data;

Translating the word problem into an algebraic equation, we have;

a + b + c = 210

b = a + 10

c = 3a

Substituting the value of b and c into the equation, we have;

a + a + 10 + 3a = 210

5a + 10 = 210

5a = 210 - 10

5a = 200

a = 200/5

a = 40

To find the value of b;

b = a + 10

b = 40 + 10

b = 50

To find c

c = 3a

c = 3*40

c = 120

10. simplify the rational expression by rationalizing the denominator.( 1 point ) 4√150/√189x

ddd [48]

Rationalizing the denominator, simply means "getting rid of that pesky root at the bottom", and we do so by simply multiplying it by something to take it out, of course, we multiply the bottom, we have to also multiply the top,

$\bf \cfrac{4\sqrt{150}}{\sqrt{189x}}\cdot \cfrac{\sqrt{189x}}{\sqrt{189x}}\implies \cfrac{4\sqrt{150}\sqrt{189x}}{(\sqrt{189x})^2}\implies \cfrac{4\sqrt{(150)({189x})}}{189x}$

$\bf \cfrac{4\sqrt{28350x}}{189x}\qquad 
\begin{cases}
28350=2\cdot 3\cdot 3\cdot 3\cdot 3\cdot 5\cdot 5\cdot 7\\
\qquad 2\cdot 3^2\cdot 3^2\cdot 5^2\cdot 7\\
\qquad 2\cdot (3^2)^2\cdot 5^2\cdot 7\\
\qquad 2\cdot (3^2\cdot 5)^2\cdot 7\\
\qquad 2\cdot (45)^2\cdot 7\\
\qquad 14\cdot 45^2
\end{cases}\implies \cfrac{4\sqrt{14\cdot 45^2}}{189x}
\\\\\\
\cfrac{4\cdot 45\sqrt{14}}{189}\implies \cfrac{180\sqrt{14}}{189x}\implies \cfrac{20\sqrt{14}}{21x}$

Jessica is planting a garden. It has the shape of a right triangle. She wants 4 plants for each square foot of area. How many p

BigorU [14]

Answer:

21 plants are in the garden

Step-by-step explanation:

here , base = 7 m

height = 24 m

Thus , The area of the triangle (garden ) is 84 m ²

he wants 4 plants for each square meter of area.

therefore , for 84 m ² number of plants are

i.e 21 plants

hence , 21 plants are in the garden
