$\frac{x { }^{2} - 2x - 6x + 12}{ (x - 6)(x + 6)} \\ \\ \frac{x(x - 2) - 6(x - 2)}{(x - 6)(x + 6)} \\ \\ \frac{(x - 2)(x - 6)}{(x - 6)(x + 6)} \\ \\ \frac{x - 2}{x + 6}$

A golf course charges $18 to golf 18 holes and $7 for a cart for a no-member.

Answer:

at least 81 times. playing 80 times would mean you played exactly what it's worth, 7*80=560, so playing 81 times means you pocket a difference of 7 dollars. if you're going to be playing at least 81 times yearly, go for the membership..

Is the line increasing or decreasing? y=-2x+5 (pls explain because im totally lost)

saveliy_v [14]

Answer:

Step-by-step explanation:

Assuming this is the slope equation

-2 is the slope

x is point x

5 is the y intercept

y is point y

the regular equation it y = mx + b

the slope is negative so it is decreasing aka gooing down

sorryy if this is the wrong answer to your question

Answer:

The food preferences among vole species are independent of one another.

Step-by-step explanation:

The hypothesis can be defined as follows:

H₀: The food preferences among vole species are independent of one another.

Hₐ: There is a relationship between voles and food preference.

The data provided is:

meadow voles common voles

apple slices 15 21

peanut butter-oatmeal 25 16

A Chi-square test for the Goodness of fit will be used.

The expected values are computed using the formula:

$E_{i}=\frac{\text{ith Row Total}\times \text{jth Column Total}}{N}$

Consider the Excel sheet attached.

The Chi-square statistic value is 2.861.

Compute the degrees of freedom as follows:

df = (r - 1)(c - 1)

= (2 - 1)(2 - 1)

= 1

Compute the p-value as follows:

$p-value=P(\chi^{2}_{(1)}>2.861)=\text{CHISQ.DIST.RT(2.861,1)}=0.091$

The p-value = 0.091 > α = 0.05

The null hypothesis will not be rejected.

Thus, it can be concluded that the food preferences among vole species are independent of one another.

PLEASE HELP ME IN MATH IM CONFUSED

Butoxors [25]

Answer:

the second choice is correct

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

y = $\frac{3}{4}$ x - 9 is in this form

with slope m = $\frac{3}{4}$

• Parallel lines have equal slopes, hence

y = $\frac{3}{4}$ x + c ← is the partial equation of the parallel line

To find c substitute (- 8, - 18) into the partial equation

- 18 = - 6 + c ⇒ c = - 18 + 6 = - 12

y = $\frac{3}{4}$ x - 12 ← equation of parallel line
