Determine whether the variable is qualitative or quantitative. Is the variable qualitative or​ quantitative? favorite rock group

Answers

Answer:

qualitative

Step-by-step explanation:

Favorite rock group is the qualitative variable because it shows an attribute. It does not depict a quantity or numbers. The favorite rock group will perform and show their ability to deliver music articles so it is showing quality not quantity. It is an attribute.

Variable is defined as the characteristic being studied so it is a qualitative variable meaning it is showing quality of the characteristic.

A local diner has started selling cupcakes and is using the bar chart given below to keep track of how many are sold each day. How many cupcakes will be sold on day n?

Answers

Answer:

a + (n-1)*4

Step-by-step explanation:

Day n could be any particular day located on the x-axis of the bar chart. Each bar represents the amount of cupcakes sold on each of the four days numbered from 1 to 4. The height of each bar marks the number of cupcakes sold. According to the chart attached, the number of cupcakes sold on each day is listed below:

Day 1 : 1 cupcake sold

Day 2 : 5 cupckaes sold

Day 3: 9 cupcakes sold

Day 4: 13 cupckaes sold

Studying the graph carefully fully, it will be observed that the number of cupcakes sold increases by a margin of 4 after day one.

As such the number of cupcakes sold in n days can be modeled by:

Using the Arithmetic progression formula:

Tn = a + (n-1)d

d = common difference, = 4

a = first term = 1

n = number of days

Hence, number sold in day n:

a + (n-1)*4

vaccinations that consisted of a total of 225 doses. How many more measles vaccines did Mr.
Potter give than polio?

Please explain the process. THX

Answers

Answer:

There are 15 more measles vaccines than polio vaccines

Step-by-step explanation:

Represent Polio with P and Measles with M

Given

5P + 3M = 225

P + M = 60

Required

How much is M greater than P; M - P

Make M the subject of formula in the second equation

[tex]M = 60 - P[/tex]

Substitute this in the first equation

[tex]5P + 3M = 225[/tex] becomes

[tex]5P + 3(60 - P) = 225[/tex]

Open the bracket

[tex]5P + 180 - 3P = 225[/tex]

Collect Like Terms

[tex]5P - 3P = 225 - 180[/tex]

[tex]2P = 45[/tex]

Divide both sides by 2

[tex]P = 22.5[/tex]

Substitute 22.5 for P in [tex]M = 60 - P[/tex]

[tex]M = 60 - 22.5[/tex]

[tex]M = 37.5[/tex]

Calculate the difference; M - P

[tex]M - P = 37.5 - 22.5[/tex]

[tex]M - P = 15[/tex]

Hence, there are 15 more measles vaccines than polio vaccines

Use the Method of Lagrange Multipliers to find the Minimum and Maximum of f(x,y) = xy subject to x^2+y^2-xy = 9 g

Answers

Answer: The Max fun is 9, and the Min fun is -3

Step-by-step explanation:

Please follow the steps carefully;

Let us consider the function f(x,y) = xy -------------- (1)

We will apply the Lagrange multipliers to maximize the function f(x,y) subject to the constraint  g(x,y) = x^2+y^2-xy = 9

By differentiating (1) w.r.t  x,   we get fx(x,y) = y

By differentiating (1) w.r.t  y,   we get fy(x,y) = x

By differentiating g(x,y) w.r.t  x,   we get gx(x,y) = 2x - y

Also By differentiating g(x,y) w.r.t  y,   we get gy(x,y) = 2y - x

let us take

fx = λgx

where y = λ(2x - y)

y/2x - y = λ  ----------- (2)

fy =  λgy

where x = λ(2y - x)

λ = x/2y -x ----------- (2)

Let us equate (2) and (3)

y/2x - y  = x/2y -x

2y² - xy = 2x² - xy

2y² = 2x² after cancelling like terms

y² = x²

So y = ±x

Now let us substitute y = x into the given constraint

x² + y² - xy = 9

x² + x² - x(x) = 9

x² = 9

therefore x = ± 3

We can conclude that when x = ±3, ⇒ y = ±3

The corresponding points are (3,3), (-3,-3)

Substitue y = -x in the given constraint gives

x² + y² - xy = 9

x² + (-x)² -x(-x) = 9

3x² = 9

x² = 3

x = ±√3

The corresponding points are (√3,-√3), (-√3,√3)

The function value is

f(x,y) = xy

f (√3,-√3) = (√3)(-√3) = -3

f (-√3,√3) = (-√3)(√3) = -3

we get;

f(3,3) = (3)(3) = 9

and

f (-3,-3) = (-3)(-3) = 9

We can conclusively say that ;

The Maximum value of the function is 9

The Minimum value of the function is -3

Answers

Answer:

Option (A) and Option (D)

Step-by-step explanation:

Point on the parabola is (x, y).

Focus given as (2, -4) and directrix of the parabola is y = -6

Therefore, distance of the point from the directrix will be,

d = |(y + 6)|

Similarly, distance of the point (x, y) from the focus will be,

d = [tex]\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]

  = [tex]\sqrt{(x-2)^2+(y+4)^2}[/tex]

Therefore, Option (A) and Option (D) will be the correct options.

Line equation => [tex] 2.1x + 9.9y - 9.2 = 0 [/tex]

Required:

x-intercept and y-intercept of the line.

SOLUTION:

The x-intercept is the point where the line intercepts the x-axis. To find the x-intercept of the line for which the equation is given above, set y = 0 and solve for x.

[tex] 2.1x + 9.9(0) - 9.2 = 0 [/tex]

[tex] 2.1x + 0 - 9.2 = 0 [/tex]

[tex] 2.1x - 9.2 = 0 [/tex]

[tex] 2.1x - 9.2 + 9.2 = 0 + 9.2 [/tex]

[tex] 2.1x = 9.2 [/tex]

[tex] \frac{2.1x}{2.1} = \frac{9.2}{2.1} [/tex]

[tex] x = 4.4 [/tex] (approximated)

The y-intercept is the point where the line intercepts the y-axis. At this point, x = 0. Set x = 0 and solve for y to find the y intercept.

[tex] 2.1(0) + 9.9y - 9.2 = 0 [/tex]

[tex] 9.9y - 9.2 = 0 [/tex]

[tex] 9.9y - 9.2 + 9.2 = 0 + 9.2 [/tex]

order the following numbers from least (top) to greatest number( bottom) . 0.40 , 0.489 , 0.430 , 0.480

Answers

Answer:

[tex]\Large \boxed{0.40 < 0.430 < 0.480 < 0.489}[/tex]

Step-by-step explanation:

First you have to see the decimal places.

Than the number of digits there is.

So this is how we make it from least to greatest!

Since there is 3 numbers after the decimals in almost all of them...

Than let’s make ‘0.40’ into 3 numbers after the decimal too.

I am sure you have heard that if you add a ‘0’ to a decimal nothing will change right?

So let’s make 0.40 into 3 numbers after the decimal just like the other numbers!

Okay so first let’s add a zero to ‘0.40’... which now this turns into ‘0.400’

Now it will be more easier to compare least to greatest!

0.400 is the least, than comes 0.430, & than would be 0.480, & finally the greatest would be 0.489

Therefore the answer is 0.40 < 0.430 < 0.480 < 0.489.

Answer:

Step-by-step explanation:

Let's take two points,

slope = (difference of y) / (difference of x)

m = (2 - - 4) / (13 - 12)

m = (2 + 4) / 1

m = 6 / 1 = 6

The slope of the line is 6.

Answer:

6

Step-by-step explanation:

The slope is the change in y over the change in x

Answer: 206

=======================================

Work Shown:

a = 3/4

b = -8

c = -2

d = 3

----------------

c-d = -2-3 = -5

(c-d)^2 = (-5)^2 = 25

a+(c-d)^2 = 3/4 + 25 = 3/4 + 100/4 = 103/4

-b * [ a + (c-d)^2 ] = -(-8)*103/4 = 8*103/4 = (8/4)*103 = 2*103 = 206

----------------

Another way to show the steps could be

[tex]-b[a+(c-d)^2]\\\\-(-8)\left[\frac{3}{4}+(-2-3)^2\right]\\\\8\left[\frac{3}{4}+(-5)^2\right]\\\\8\left(\frac{3}{4}+25\right)\\\\8\left(\frac{3}{4}+\frac{100}{4}\right)\\\\8\left(\frac{3+100}{4}\right)\\\\8\left(\frac{103}{4}\right)\\\\\frac{8}{4}*103\\\\2*103\\\\206\\\\[/tex]

Which is more or less the same thing as the previous section.

----------------

So ultimately,

[tex]-b[a+(c-d)^2] = 206[/tex]

when a = 3/4, b = -8, c = -2, and d = 3.

multiply 1705.07 by 15 = 25,576.05

Now multiply 25,576.05 by 1000 (thats how many milliliters are in 1 liter) = 25,576,050

The number of water molecules is 2.505 x 10²⁵.

What is an expression?

Expression in maths is defined as the collection of the numbers variables and functions by using signs like addition, subtraction, multiplication, and division.

Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.

Given that one milliliter has about 15 drops. One drop of water has 1.67 x 10²¹ H, O (water) molecules.

Multiply 1.67 by 10²¹ = 1.67 x  10²¹

Multiply 1.67 x  10²¹ by 15 = 2.505 x 10²²

Now multiply 2.505 x 10²² by 1000 (that's how many mill liters are in 1 liter) 2.505 x 10²⁵.

Therefore, the number of water molecules is 2.505 x 10²⁵.
