Find an equation of the vertical line through (3 comma negative 1 )in the form axplusbyequalsc, where a, b, and c are integers

Sati [7]

The equation of the vertical line is $1x+0y=3$

Explanation:

It is given that the vertical line passes through the points $(3,-1)$

For vertical line, the slope is undefined.

Hence, $b=0$

Let us substitute the coordinate $(3,-1)$ in the equation $ax+by=c$ , we have,

$3a+0y=c$

Simplifying, we have,

$3a=c$

$3=\frac{c}{a}$

where $a=1$ and $c=3$

Substituting the values of a, b and c in the equation $ax+by=c$ , we have,

$1x+0y=3$

Thus, the equation of the vertical line is $1x+0y=3$

For a sample of eight bears, researchers measured the distances around the bears' chests and weighed the bears. Minitab was us

Yakvenalex [24]

Answer:

There is a linear correlation between the chest size and weight

Proportion of the variation in weight can be explained by the linear relationship between weight and chest size is 0.006724 .

Step-by-step explanation:

Null Hypothesis: $H_0$ = There is no linear correlation between the chest size and weight

Alternative Hypothesis : $H_a$ =There is a linear correlation between the chest size and weight

The value of the linear correlation coefficient is r=0.882.

n = 8

Formula : $t=\frac{r\sqrt{n-2}}{\sqrt{1-r^2}}$

$t=\frac{0.882\sqrt{8-2}}{\sqrt{1-(0.882)^2}}$

$t=4.584$

Degree of freedom = n-1 = 8-1 = 7

α =0.05

so, p value is 2.365

t calculated > t critical

So, we reject the null hypothesis

So, There is a linear correlation between the chest size and weight

The proportion of the variation in weight can be explained by the linear relationship between weight and chest size = $r^2 = (0.082)^2=0.006724$

Hence proportion of the variation in weight can be explained by the linear relationship between weight and chest size is 0.006724 and There is a linear correlation between the chest size and weight

I need help on these questions PLEASE

nordsb [41]

<span>I think the easiest way to answer all of these is to just go ahead and find the equation of the line first.

I'm pretty sure that by the time you reach this problem, you've learned to find
the equation of a line that passes through two given points. You have two points: (2, 100) and (5, 205). The equation of the line through them is [ y = 35x + 30 ].

6). The initial membership fee ... the cost for walking in the door and signing up,
before any months, is $30. (Also the y-intercept.)

7). The cost per month is $35. (The slope of the line.)

8). We already did that, up above. [ y = 35x + 30 ].

9). 'x' in the equation is the number of months.
There are 12 months in one year.

y = 35(12) + 30 = $450</span>
