see the attached figure with letter to better understand the problem

we know that

If triangle ABC is similar to triangle PQR

then

the ratio of the corresponding sides are proportional

substitute the values

therefore

the answer is the option C

sveta [45]

Answer:

Step-by-step explanation:

The mean of a set of numbers is the sum divided by the number of terms.

x¯= <u>25+10+16+39+27+25+32+25+25+22+28+14</u>

<h3>Simplify the numerator. </h3>

x¯ = <u>261.27</u>

<h3>Divide 261.27 by 11 </h3>

x¯= 23.75 18

<h3>Divide. </h3>

x¯= 23.75 18

The mean should be rounded to one more decimal place than the original data. If the original data were mixed, round to one decimal place more than the least precise.

x¯=23.8

<h3>Simplify each value in the list. </h3>

Set up the formula for sample standard deviation. The standard deviation of a set of values is a measure of the spread of its values.

s= n^∑ i=1 √(<u>xi−xavg</u>)²

N-1

Set up the formula for standard deviation for this set of numbers.

s= ⎷(25−23.8)²+(10−23.8)²+(16−23.8)²+(39.27−23.8)²+(25−23.8)²+<u>(32−23.8)²+(25−23.8)²+(25−23.8)²+(22−23.8)²+(28−23.8)²+(14−23.8)</u>²

11−1

<h3>Simplify the result. </h3>

s= √68.05209

The standard deviation should be rounded to one more decimal place than the original data. If the original data were mixed, round to one decimal place more than the least precise.

Hello,

$\frac{7}{10} - \frac{3}{10}$ = 2/5

Solution.

<span> $\frac{7}{10} - \frac{3}{10}$ = The denominators are the same so you subtract the numerator. Your answer should be </span> $\frac{4}{10}$ simplified your answer is $\frac{2}{5}$ .

1) 3r² – 2r=-9<br> Quadratic formula

Nonamiya [84]

Answer:

Solving the equation $3r^2-2r=-9$ using quadratic formula we get: $\mathbf{ r=\frac{1+\sqrt{26}\:i}{3}\:or\: r=\frac{1-\sqrt{26}\:i}{3}}$

Step-by-step explanation:

We need to solve the equation $3r^2-2r=-9$ using quadratic formula.

The quadratic formula is: $r=\frac{-b\pm\sqrt{b^2-4ac}}{2a}$

For the given equation: $3r^2-2r=-9$

We can write it as: $3r^2-2r+9=0$

We have a = 3, b= -2 and c=9

Putting values in quadratic formula and finding value of r

$r=\frac{-b\pm\sqrt{b^2-4ac}}{2a}\\r=\frac{-(-2)\pm\sqrt{(-2)^2-4(3)(9)}}{2(3)}\\r=\frac{2\pm\sqrt{4-108}}{6}\\r=\frac{2\pm\sqrt{-104}}{6}\\We\:know\:that: \sqrt{-1}=i\\ r=\frac{2\pm\sqrt{26} \:i}{6}\\ r=\frac{2+2\sqrt{26}\:i}{6}\:or\: r=\frac{2-2\sqrt{26}\:i}{6}\\ r=\frac{2(1+\sqrt{26}\:i)}{6}\:or\: r=\frac{2(1-\sqrt{26}\:i)}{6}\\ r=\frac{1+\sqrt{26}\:i}{3}\:or\: r=\frac{1-\sqrt{26}\:i}{3}$

So, solving the equation $3r^2-2r=-9$ using quadratic formula we get: $\mathbf{ r=\frac{1+\sqrt{26}\:i}{3}\:or\: r=\frac{1-\sqrt{26}\:i}{3}}$
