Find the midpoint of the line segment from (1,-1) to (2,4)

Answer:

[tex](-1)+(-3)=-4[/tex]

Step-by-step explanation:

We were originally on -1.

But we jumped to -4.

-4 is 3 spaces to the left of -1.

In other words, we subtract 3 into -1.

Another way of saying this is that we added -3 to -1.

Therefore, our equation is:

[tex](-1)+(-3)=-4[/tex]

Answer: Jen is wrong about her classification.

Step-by-step explanation:

First of all, we know that the definition of an irrational number is that they are numbers that cannot be represented by a simple fraction and that they are never repeating decimals and they never end.

So, considering this, Jen is wrong because, yes it does not repeat but it DOES END unless it is not written in this problem that it continues on irrationally like pi. Hence, this number is not irrational.

The Jen classifies the number 4.567 as an irrational number is false.

It is required to find the number is rational and irrational numbers.

Real numbers are numbers that include both rational and irrational numbers. Rational numbers such as integers (-2, 0, 1), fractions(1/2, 2.5) and irrational numbers such as √3, π(22/7), etc., are all real numbers.

Given :

Jen's argument

We have

4.567 as an irrational number

The above claim is false because

4.567 =

4567/1000

When we divide the above number in the form of p/q  and q≠0 then then number is rational number.

Therefore, the Jen classifies the number 4.567 as an irrational number is false.

Answer:

The answer is 3.14 * 10^-6

Answer:

3.1415 * 10^6

Step-by-step explanation:

Scientific notation is  of the form a* 10 ^b where a is between 1 and less than 10

3,141,500  

Move the decimal 6 places to the left

The exponent is the number of places you move the decimal

Since we move it to the left, it is positive

3.141500 * 10^6

Drop the trailing zeros

3.1415 * 10^6

Answer:

greater

Step-by-step explanation:

The domain is the number that x can be

sqrt(x-3) must be greater than or equal to zero

x-3  must be greater than or equal to zero

x must be greater than or equal to  three

The other restriction is x+2 cannot equal zero

x cannot equal -2

The first restriction is more restrictive so that is the one we go with

Answer:

- 4

Step-by-step explanation:

The slope of the line is the average rate of change of f(x)

The equation of a line in slope- intercept form is

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

f(x) = - 4x + 1 ← is in slope- intercept form

with m = - 4 ← average rate of change

Turn the percentage into a decimal.

24.10 / 100 = 0.241

Divide.

195.21 / 0.241 = 810

Therefore, 195.21 is 24.10% of 810

Answer:

mean of this demand distribution = 100

Step-by-step explanation:

To find the mean of this demand distribution;

Mean = Expected vale = E[x]

for discrete provability function,

we say E[x] = ∑(x.p(x))

x     p(x)     x.p(x)

10     0.1     1

30    0.4    12

60    0.4    24

90    0.7    63

∴ ∑(x.p(x)) = ( 1 + 12 + 24 + 63 )

∑(x.p(x)) = 100

Answer:

449.50

Step-by-step explanation:

because gross pay is before taxes and everything else and he worked 29 hours so 15.50 × 29 = $449.50

The amount of money that Hector works in a gas station will be $449.50.

Algebra is the study of abstract symbols, while logic is the manipulation of all those ideas.

The acronym PEMDAS stands for Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This approach is used to answer the problem correctly and completely.

Hector works in a service station and procures $15.50 each hour. Last week he worked 29 hours.

The total cost that Hector can earn will be given as,

⇒ $15.50 x 29

⇒ $449.5

The gross pay that Hector works in a corner store will be $449.50.

Step-by-step explanation:

As ratio of desktops to laptops=3:4

Take no. of desktops= 3x

Take no. of Laptops=4x

Total no. of desktops+ Total no. of laptops = Total no. of computers

3x+4x=70

7x=70

x=10

Hence, the total no, of desktops= 3x

Hence, Total no. of desktops= 3×10

Answer:

2.7 meters

Step-by-step explanation:

So, we know that 1 foot is about 0.305 meters.

To find how many meters are in 9 feet, multiply 0.305 by 9.

Therefore:

[tex]9(1\text{ foot})=9(0.305\text{ meters})[/tex]

Multiply:

[tex]9\text{ feet}=2.745\text{ meters}[/tex]

To the nearest, tenth this would be 2.7 meters.

Answer:

The oldest person is 25 years old

Step-by-step explanation:

Represent David's age by d.

Then Dan's age is d + 5, and Bridget's is d - 8.

The sum of these three ages is 57:

d + (d + 5) + (d - 8) = 57

This simplifies to

3d - 3 = 57, or 3d = 60.  Then d must be 20.

David is 20, Dan is 25 (5 years older than David), and Bridget is 12 (8 years younger than David).

Check:  Do these three ages add up to 57?

20 + 25 + 12 = 57   YES\

The oldest person is 25 years old.  That's Dan's age.

Answer:

it is the same 4.3

Step-by-step explanation:

this numbers didn't add one number when you round(0,1,2.3.4)

this numbers(5,6,7,8,9), you add one number when you add

4.3 (the three is the tenth)and no number after it so its stell the same

The rounding number of 4.3 when rounded to the nearest tenth is 4.3

Here,

The number is 4.3

We have to find the rounding number of 4.3 nearest tenth.

What is Rounding number?

A method of approximating a number to its nearest place value is called Rounding of Numbers.

Now,

The number is 4.3

To round the decimal number to its nearest tenth, look at the hundredth place.

But here is no any number on hundredth number, hence no change occur for rounding 4.3 to the nearest tenth.

So, The rounding number of 4.3 when rounded to the nearest tenth is same as the number 4.3

Answer:

[tex]$ x_1^2 + z_1^2 = y_1^2$[/tex]

Step-by-step explanation:

Let   [tex]$ p(x_1, y_1, z_1)$[/tex]  be the point.

Any point on y-axis is (0, y, 0)

So, distance is

= [tex]$ \sqrt{x_1^2+0 + z_1^2} $[/tex]

= [tex]$ \sqrt{x_1^2 + z_1^2} $[/tex]   ......(1)

Now any point on x-z plane is [tex]$ ( x_1, 0, z_1 ) $[/tex]

Distance from p to this point is

= [tex]$ \sqrt{0+y_1^2 + 0} $[/tex]

= [tex]$\sqrt{y_1^2}$[/tex]    .........(2)

Equating (1) and (2), we get

[tex]$ \sqrt{x_1^2 + z_1^2} = \sqrt{y_1^2}$[/tex]

[tex]$ x_1^2 + z_1^2 = y_1^2$[/tex]

Answer: y=-13/12x-7

Step-by-step explanation:

To find the slope-intercept form, we first need to find the slope. To find the slope, you use the formula [tex]m=\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]. We use the two given points to find the slope.

[tex]m=\frac{32-6}{-36-(-12)} =\frac{26}{-24} =-\frac{13}{12}[/tex]

Now that we have our slope, we can start filling out the slope-intercept form equation.

y=mx+b

y=-13/12x+b

Since we don't know the y-intercept, we can use one of the given points and solve for b.

6=(-13/12)(-12)+b                              [multiply (-13/12) and -12]

6=13+b                                              [subtract both sides by 13]

b=-7

With the y-intercept, we can complete our equation.

y=-13/12x-7

630,400,000

Step-by-step explanation:

630,379,982

The 3 above that is bold, between the 0 and the 7, is in the hundred thousands place.

To round to a place, change all digits to the right of that place to zero. If the digit immediately to the right is 0 through 4, you're done. If the digit immediately to the right is from 5 to 9, then you raise the digit you are rounding to by 1.

Step 1. Make all digits to the right of the hundred thousands digit 0.

630,300,000

Step 2. Since the digit immediately to the right of the hundred thousands digit was a 7, which is from 5 to 9, the digit we are rounding to goes up by 1. The 3 becomes 4.

Answer:

y = 7.8x + 26

Step-by-step explanation:

Given the following :

Pearson's r = 0.78

Average consumption of ice cream = 5 grams per week (m) with Standard deviation (sd) = 1.5 grams

Average weight = 65 kg with standard deviation of 15kg

Formular for the regression line :

General regression formula :

y = mx + c

y = predicted variable ; m = slope or gradient ; x = predictor variable ; c = intercept

Gradient (m) = change in y / change in x

m = (sd y / sd x) * r

m = (sd weight / sd ice cream) × r

m = (15 / 1.5) × r

m = 10 × 0.78 = 7.8

Intercept:

mean of weight(y) - [Slope×mean of icecream(x)]

65 - [7.8 × 5]

65 - 39 = 26

Hence,

y = 7.8x + 26

Answer:

200,300,290,320,340

Step-by-step explanation:

If the mean of five numbers = 290

Then the total sum of the five numbers should be= 290*5

= 1450

an example of a set of five different numbers whose mean is 290

= 200,300,290,320,340

Summation of the above

=( 200+300+290+320+340)

= 1450

So the above set of numbers is a good example of a set of five different numbers whose mean is 290
