What Is The Measure Of Angle X

Answers

Answer 1

Answer:

x =83

Step-by-step explanation:

supplementary angles add to 180 degrees

x+y = 180

We know y is 97

x+97= 180

Subtract 97 from each side

x+97-97= 180-97

x =83

Answer 2

Answer:

It is 83

Step-by-step explanation:

Supplementary is 180 degrees

180-97=83

John recorded the weight of his dog Spot at different ages as shown in the scatter plot below.




Part A:
Write an equation that would describe the line of best fit.


Part B:
Using the line of best fit, make a prediction of Spot's weight after 18 months.

Answers

Answer:

A) y = 1.875x + 1.25

B) 35 pounds

Step-by-step explanation:

A) We need two points to define a line. To find an equation that would describe the line of best fit, we can use one of the first points and one of the last points. Let's use (2, 5) and (10, 20).

General equation of a line:

y = mx + b

Slope of the line:

m = (20 - 5)/(10 - 2) = 1.875

y-intercept is found replacing a known point and the slope into the general  equation:

5 = 1.875*2 + b

b = 5 - 1.875*2 = 1.25

The final equation is:

y = 1.875x + 1.25

where y represents weight (in pounds) and x represents age (in months)

B) At x = 18:

y = 1.875*18 + 1.25 = 35

Answers

Answer:

26

Step-by-step explanation:

The mean absolute deviation of the data is 11.

The mean absolute deviation (MAD) of a data set is the average distance between each data value and the mean.

To find the mean absolute deviation of the data, start by finding the mean of the data set. Find the sum of the data values, and divide the sum by the number of data values.

Given: The data below show the weights, in pounds, of a group of professional football players.

325, 310, 289, 288, 285, 285, 285, 280, 280, 273

The mean of the data set is 290 pounds.

How to find the mean absolute deviation of the data

set, to the nearest whole number?

The average absolute deviation is

[(325-290)+(310-290)+|(289-290)|+|(288-290)|+3|(280-290)|+21(280-290)|+|(273-290)|]/10

=> (35+20+1+2+5+5+5+10+10+17)/10

=> 11.

The density of oxygen is 0.001332 gram per cubic meter. Represent 0.001332 in scientific notation.

Answers

Answer:

1.332 × 10-3

Step-by-step explanation:

you move the decimal point to the right until there's only one digit on the left side of it. the exponent is 3 because that's the number of places you moved the decimal point, and it's negative because you moved it to the right. if you move the decimal to the left it is positive, to the right is negative :)

By basic calculation We can represent 0.001332 in scientific notation as [tex]1.332\times 10^{-3}[/tex]

What is scientific notation?

Scientific notation is a way of expressing numbers big numbers in short form with approximate values.

Given number is 0.001332

we can write 0.001332 as

1332/1000000

or we can write it as

1.332/1000

and now we can write it in Scientific notation form as  

[tex]\frac{1.332}{10^3}\\\\1.332\times 10^{-3}[/tex]
