ask your self frist how many months is in 6 years that would be 72 months .....so now you have 8.5% interest on the amount of $4280 for 72 months.....the interest gained in 72 months would be $3047.37......$4280+$3047= $8727. I think but not 100% sure

What is the equation of this graphed line?

Veseljchak [2.6K]

Answer:

Slope Intercept form of the equation is $y = \frac{1}{3} x - 9$

Step-by-step explanation:

Here, the two point line are given as is A(-6,-3) and B(6,-7)

The slope of the line AB = $m = \frac{y_2 - y_1}{x_2 - x_1}$

$m = \frac{-7-(-3)}{6-(-6)} = \frac{-7 + 3}{6 + 6} = \frac{4}{12} \\\implies m = \frac{1}{3}$

⇒ the slope of AB is m = (4/3)

By SLOPE INTERCEPT FORMULA:

The equation of a line with slope m and a point (x0, y0) is given as

(y-y0)= m (x-x0)

⇒ The equation of line with point (6,-7) is:

$y + 7 = \frac{1}{3} (x-6) \implies 3y + 21 - x + 6 - 0\\or, -x + 3y + 27 = 0$

Now, the given equation is -x + 3y = -27

Convert it in the SLOPE INTERCEPT FORM y = mx + c

We get, 3y = x - 27

or, $y = \frac{1}{3} x - \frac{27}{3} \\\implies y = \frac{1}{3} x - 9$

Hence, the Slope Intercept form of the equation is $y = \frac{1}{3} x - 9$

Which of the following can be classified as Discrete and Quantitative data. The number of students in your school. The different

WITCHER [35]

Answer:

a) The number of students in your school.

Step-by-step explanation:

Quantitative and Qualitative:

The data that can be expressed with the help of numerical are know as quantitative variable.
Qualitative variable is the non parametric variable and numerical does not describe the data

Discrete and Continuous data:

Discrete data are expressed in whole number and cannot take all the values within an interval.
Continuous variable can be expressed in decimals and can take any value within an interval.

a) The number of students in your school.

Since whole numbers are used to express number of children it is a discrete and continuous data.

b) The different colors of the eyes of your classmates.

These are qualitative data and numerical are not used to express them.

c) The height of all the people in your neighborhood.

These are continuous data as height is measured and can be expressed in decimals.

d) The acceleration of your car as you drive to school.

These are continuous data as acceleration is measured and can be expressed in decimals.

the scale on a map is stated as 1 : 250000 2 villages are 9 m apart on the map how far from each other are the two villages in k

Sergio039 [100]

Answer:

2,250,000 km

Step-by-step explanation:

From the above question our scale is given as:

1 m : 250000km

We are trying to find the distance between two villages which is 9m apart in kilometers

Hence

1 m : 250000km

= 1 m = 250000km

9m = x km

Cross Multiply

x km = 9 × 250,000km

x km = 2,250,000 km
