Answer: If you want to find the x and y intercepts, your answer would be...

x-intercept - (-4,0)

y-intercept - (0,2)

Step-by-step explanation:

To find the x-intercept, substitute in 0 for y and solve for x. To find the y-intercept, substitute in 0 for x and solve for y.

I hope this helps you out! ☺

Given data

1. The mean

$\frac{\sum fx}{\sum f}=\frac{505}{66}=7.6515$

2. The median

$\begin{gathered} \text{ Median = (}\frac{\text{N+1}}{2})th \\ =(\frac{66+1}{2})th=(\frac{67}{2})th=33.5th \\ \text{The median is the 33.5th }term\text{ which is between 7 and 8} \\ \text{The median is }\frac{\text{7+8}}{2}=\frac{15}{2}=7.5 \end{gathered}$

3. The sample standard deviation

$\begin{gathered} SD\text{ =}\sqrt[]{\frac{\sum f|x-\bar{x}|}{\sum f}} \\ \bar{x}=7.6515 \\ SD=\sqrt[]{4.8028} \\ SD=2.1915 \end{gathered}$

Answer:

$\frac{5}{-1.6}$

Step-by-step explanation:

We will solve the given expressions and find the answer in decimals.

1). $5\frac{6}{15}+(-2\frac{4}{5})$ = $5\frac{2}{5}-2\frac{4}{5}$

= 5.4 - 2.8

= 2.6

2). $-3\frac{3}{10}-(-\frac{7}{20})=-3\frac{3}{10}+\frac{7}{20}$

= -3.3 + 0.35

= -2.95

3). $\frac{5}{-1.6}=-\frac{5}{1.6}$

= -3.125

4). (-4.5) × (-2.3) = 10.35

Solution of the expressions in the increasing order will be,

-3.125 < -2.95 < 2.6 < 10.35

$\frac{5}{-1.6}$

What is (6,1) negative one half in point slope form

matrenka [14]

Answer: y - 1 = $-\frac{1}{2}$ (x - 6)

<u>Step-by-step explanation:</u>

Point-Slope form: y - y₁ = m(x - x₁) <em>where m is slope and (x₁, y₁) is the point</em>

m = $-\frac{1}{2}$ (x₁, y₁) = (6, 1)

y - 1 = $-\frac{1}{2}$ (x - 6)
