17. The letter is J

The letter appears 3 times

18. Lefthanded students = 4 students

<h3>How to determine the factors</h3>

17. We have that 1/4 of the months of the year start with the same letter

It is important to note that:

January, June and July all start with the same letter

The letter is J

The letter appears 3 times

18. Total number of students = 24

5/ 6 are right handed

Right handed students = 24 × 5/ 6 = 4 × 5 = 20 students

Lefthanded students = 24 - righthanded students

Lefthanded students = 24 - 20

Lefthanded students = 4 students

Thus, we can see that the letter that appear in 3 months of the year is J

Complete the equation of the line through (-10,-7)(−10,−7)(, minus, 10, comma, minus, 7, )and (-5,-9)(−5,−9)(, minus, 5, comma,

Tanzania [10]

Answer:

$y = -\frac{2}{5}\cdot x - 11$

Step-by-step explanation:

First, the slope is determined by using the following expression:

$m = \frac{y_{2}-y_{1}}{x_{2}-x_{1}}$

$m = \frac{-7-(-9)}{-10 - (-5)}$

$m = -\frac{2}{5}$

The y-intercept is found by using the line equation, the slope and one point:

$y = m \cdot x +b$

$b = y - m\cdot x$

$b = -7 - \left(-\frac{2}{5}\right)\cdot (-10)$

$b = -11$

The equation of the line is:

$y = -\frac{2}{5}\cdot x - 11$

The Beechcraft 1900D is a commuter airplane with a fuel capacity of 665 gallons. The function that represents how the amount of

nalin [4]

Given:

The function that represents how the amount of fuel changes as a function of distance flown is

$f(x)=-0.9x+665$

where x represents miles flown, and f(x) represents the amount of fuel remaining.

To find:

The rate of change for this scenario.

Solution:

The slope intercept form of a linear function is

$y=mx+b$ ...(i)

Where, m is the slope or rate of change and b is the y-intercept.

We have,

$f(x)=-0.9x+665$ ...(ii)

On comparing (i) and (ii), we get

$m=-0.9$

Therefore, the rate of change for this scenario is -0.9. It means, the amount of fuel in the airplane is decreasing by 0.9 gallons per mile.
