Find the distance, c, between (–4, –3) and (2, 1) on the coordinate plane. Round to the nearest tenth if necessary.

Answers

Answer:

d=√((x_2-x_1)²+(y_2-y_1)²)

d=√((2-(-4))²+(1-(-3))²)

d=√(6²+4²)

d=√36+16

d=√52

d=7.21110255...

d=7.2

Step-by-step explanation:

d=7.2

The distance between the points on the coordinate plane is 7.2 units.

What is coordinate geometry?

Coordinate geometry is the study of geometry using the coordinate points.  It provides a link between geometry and algebra through line graphs and curves.

For the given situation,

The points are (x1, y1) be (–4, –3) and (x2, y2) be (2, 1)

The formula for the distance between points,

[tex]d=\sqrt{(x2-x1)^{2}+(y2-y1)^{2} }[/tex]

On substituting the above points,

⇒ [tex]d=\sqrt{(2-(-4))^{2}+(1-(-3))^{2} }[/tex]

⇒ [tex]d=\sqrt{6^{2}+4^{2} }[/tex]

⇒ [tex]d=\sqrt{52}[/tex]

⇒ [tex]d=7.211[/tex] ≈ [tex]7.2[/tex]

Hence we can conclude that the distance between the points on the coordinate plane is 7.2 units.

The students in the After-School Club ate 12 grapes per minute. After 9 minutes, there were 32 grapes remaining. The table shows the number of carrots remaining after different amounts of time. Which snack did the students eat at a faster rate? Explain.​

Answers

Answer:

Grapes

Step-by-step explanation:

The rate of change for the grapes was -12 grapes per minute.

To calculate the rate of change for the carrots, use the slope formula [tex]m = \frac{y_{1}-y_{2} }{x_{1}-x_{2} }[/tex]. In this case, m is the rate of change, time is x, and the carrots remaining is y.

[tex]m = \frac{118-136}{8-6} = \frac{-18}{2} = -9[/tex]

The decrease in grapes was much greater than the decrease in carrots, so therfore the students ate the grapes at a faster rate.

If the table shows the number of carrots remaining after different amounts of time. The students eat grapes at a faster rate.

What is the rate of change?

It is defined as the change in values of a dependent variable with respect to the independent variables.

It is given that, the students in the After-School Club ate 12 grapes per minute. After 9 minutes, there were 32 grapes remaining.

Grapes were changing at a pace of -12 grapes per minute. Use the slope formula to get the rate of change for the carrots.

m=118-136/8-6

m=-18/2

m=-9

The students consumed the grapes more quickly because the decline in grapes was significantly larger than the decline in carrots.

Thus, the table shows the number of carrots remaining after different amounts of time. The students eat grapes at a faster rate.

What is the outlier in the following data set:
15,11,10,8,9,1,8,7,5,4,2,3, and 37?

Answers

Step-by-step explanation:

The steps to find an outlier:

1. Put the data in numerical order.

2. Find the median.

3. Find the medians for the top and bottom parts of the data. This divides the data into 4 equal parts.

The median with the smallest value is called Q1. The median for all the values - usually just called the median is also called Q2. The median with the largest value is Q3.

4. Subtract...Q3 - Q1. This value is the InterQuartileRange or IQR. Remember that the range means taking the largest minus the smallest. This is a special range having to do with the quartiles.

5. Multiply...1.5 * IQR

6. Take your answer from #5 and do 2 things with it. A). Subtract it from Q1 and B) Additional to Q3.

7. Look at all your data points. If any are SMALLER than Q1 - 1.5 *IQR, they are outliers. If any are LARGER than Q3 + 1.5 *IQR, they are also outliers.

For your data....the median, Q2 is

(43+38)/2 = 40.5.

Q1 = (30+26)/2 = 28.

Q3 = (54+52)/2 = 53

The IQR is 53 - 28 = 25

1.5 * IQR = 37.5

Q1 - 37.5 = 28 - 37.5 = -9.5. There is no data value less than -9.5.

Q3 + 37.5 = 53 + 37.5 = 90.5. there is no data value greater than 90.5.

My conclusion is that there are no outliers in this data.

I hope this helps!

Convert 5 ounces into kilograms. Round your answer to the nearest hundredth.

Answers

Answer:

Answer: 0.141 kilos

0.141748

Step-by-step explanation:

The conversion is 0.1417475 Kg

What is Unit conversion?

Conversion of units is the conversion between different units of measurement for the same quantity, typically through multiplicative conversion factors which change the measured quantity value without changing its effects.

given:

5 ounces

So, to convert ounces to kilogram we have

1 ounce = 0.0283495 Kg

So, 5 ounces = 5* 0.0283495

5 ounces = 0.1417475 Kg

Hence, 5 ounces = 0.1417475 Kg
