Hey!

-------------------------------------------------

The range in a data is the value of subtracting the highest value to the lowest value.

-------------------------------------------------

First, we need to the the values in order from least to greatest.

26, 27, 27, 30, 32, 33, 33, 34, 40, 45

Second, we subtract the greatest value to least value.

45 - 26 = 19

-------------------------------------------------

Hence, the range is 19!

-------------------------------------------------

Hope This Helped! Good Luck!

Can someone help me find the scale factor and the missing sides please?
Vanyuwa [196]

Answer:

x = 6, y = 45

Step-by-step explanation:

scale \: factor =  \frac{13}{32.5}  \\  =  \frac{2}{5}   \\  \\  \frac{x}{15} =  \frac{18}{y}   =  \frac{2}{5}  \\  \\ \implies  \frac{x}{15}  =  \frac{2}{5}  \\  \\ x =  \frac{2 \times 15}{5}  \\  \\ x = 6 \\  \\ \frac{18}{y}   =  \frac{2}{5} \\  \\ y =  \frac{5 \times 18}{2}  \\  \\ y = 45

Phyllis invested 47000 dollars, a portion earning a simple interest rate of 4 percent per year and the rest earning a rate of 6
Alexandra [31]

Answer:

31000 dollars were invested at 4% interest rate.

16000 dollars were invested at 5% interest rate.

Step-by-step explanation:

Convert the interest rate into decimal and then write down two equations to solve for the unknowns.

\begin{bmatrix}0.04x+0.06y=2200\\ x+y=47000\end{bmatrix}

\mathrm{The\:solutions\:to\:the\:system\:of\:equations\:are:}\\\\x=31000,\:y=16000

Best Regards!

What is the equation of this line in standard form? 8x−7y=−25 8x−9y=23 8x−9y=−23 9x−8y=23 Number graph ranging from negative fiv
Gnoma [55]

Answer:

The equation of line is:

8x-9y=-23

Step-by-step explanation:

We are given that a graph is  a that passes through two points:

(-4,-1) and (\dfrac{1}{2},3)

We know that the equation of line passing through two points:

(a,b) and (c,d) is given by:

y-b=\dfrac{d-b}{b-a}\times (x-a)

Here we have:

(a,b)=(-4,-1) and (c,d)=(\dfrac{1}{2},3)

Hence, the equation of line is:

y-(-1)=\dfrac{3-(-1)}{\dfrac{1}{2}-(-4)}\times (x-(-4))\\\\y+1=\dfrac{3+1}{\dfrac{1}{2}+4}\times (x+4)\\\\y+1=\dfrac{4}{\dfrac{9}{2}}\times (x+4)\\\\y+1=\dfrac{4\times 2}{9}\times (x+4)\\\\y+1=\dfrac{8}{9}\times (x+4)\\\\9\times (y+1)=8\times (x+4)\\\\9y+9=8x+8\times 4\\\\9y+9=8x+32\\\\8x-9y=9-32\\\\8x-9y=-23

Hence the equation of line is:

8x-9y=-23
