brilliants [131]

Answer:

a) $\bar{x}$ =4.63 md=4.55 mo= 1.9 b) Sample Standard Deviation≈ 2.58 Coefficient of Variation=55.72% Sample Range=6.9

Step-by-step explanation:

Mean

$a)\bar{x}=\frac{1.9+ 2.3+ 5.7+ 5.2+ 1.9+ 8.8+ 3.9+ 7.3}{8} =\frac{37}{8}=4.625=\approx 4.63$

For the Median, we have to order the entries. So, ordering it goes:

1.9 1.9 2.3 3.9 5.2 5.7 7.3 8.8

Since we have even entries $\frac{\frac{n}{2}+\frac{n}{2} +1}{2}=\frac{4th+5th}{2}=\frac{3.9+5.2}{2}=4.55$

mode

The mode for this data 1.9 1.9 2.3 3.9 5.2 5.7 7.3 8.8 is 1.9

Sample Standard Deviation

Here it is the formula to calculate it:

$_{x}=\sqrt{\frac{\sum (x_{i}-\bar{x})^{2}}{n-1}}\\ S_{x}=\sqrt{\frac{46.855}{7}}\approx 2.58$

Coefficient of Variation

CV is the quocient between sample Standard deviation over Mean and it is used to make comparisons.

$CV=\frac{S_x}{\bar{x}}*100%=\frac{2.58}{4.63} \approx 55.72%$

Range

The difference between the highest and the lowest value of this sample

8.8-1.9=6.9

$1)\\\frac{3}{7}x+3=\frac{1}{8}\ \ \ \ |multiply\ both\ sides\ by\ LCD(\frac{3}{7};\ \frac{1}{8})=56\\\\56\times\frac{3}{7}x+56\times3=56\times\frac{1}{8}\\\\8\times3x+168=7\\\\\boxed{\boxed{24x+168=7}}\ \ \ \ |subtract\ 168\ from\ both\ sides\\\\24x=161\ \ \ \ \ |divide\ both\ sides\ by\ 24\\\\\boxed{x=\frac{161}{24}}$

$2)\\\frac{1}{6}x-4=\frac{2}{9}\ \ \ \ |multiply\ both\ sides\ by\ LCD(\frac{1}{6};\ \frac{2}{9})=18\\\\18\times\frac{1}{6}x-18\times4=18\times\frac{2}{9}\\\\3x-72=2\times2\\\\\boxed{\boxed{3x-72=4}}\ \ \ \ \ |add\ 72\ to\ both\ sides\\\\3x=76\ \ \ \ \ \ |divide\ both\ sides\ by\ 3\\\\\boxed{x=\frac{76}{3}}$

$3)\\\frac{5}{8}x-10=\frac{3}{4}\ \ \ \ \ |multiply\ both\ sides\ by\ LCD(\frac{5}{8};\ \frac{3}{4})=8\\\\8\times\frac{5}{8}x-8\times10=8\times\frac{3}{4}\\\\5x-80=2\times3\\\\\boxed{\boxed{5x-80=6}}\ \ \ \ \ |add\ 80\ to\ both\ sides\\\\5x=86\ \ \ \ \ \ |divide\ both\ sides\ by\ 5\\\\\boxed{x=\frac{86}{5}}$

$4)\\\frac{4}{5}x-12=\frac{3}{4}\ \ \ \ \ \ |multiply\ both\ sides\ by\ LCD(\frac{4}{5};\ \frac{3}{4})=20\\\\20\times\frac{4}{5}x-20\times12=20\times\frac{3}{4}\\\\4\times4x-240=5\times3\\\\\boxed{\boxed{16x-240=15}}\ \ \ \ \ |add\ 240\ to\ both\ sides\\\\16x=255\ \ \ \ \ |divide\ both\ sides\ by\ 16\\\\\boxed{x=\frac{255}{16}}$

What is the y-intercept?

Reika [66]

Answer:

(0, 9)

Step-by-step explanation:

The y-intercept is the point when x = 0. By looking at the graph, when x = 0, y = 9. Therefore, the y-intercept of the line is (0, 9).
