After doing mathematical operations, we can conclude that it would take is 12 months to buy the smart-watch for $229.95 if we save $20 per month.

What are mathematical operations?An operation is a function in mathematics that transforms zero or more input values into a clearly defined output value. The operation's arity is determined by the number of operands. The rules that specify the order in which we should solve an expression involving multiple operations are known as the order of operations. PEMDAS stands for Parentheses, Exponents, Multiplication, Division, Addition, and Subtraction (from left to right).

Determine whether the data described below are qualitative or quantitative and explain why.
The blood groups of A, B, AB, and O
Choose the correct answer below.
OA. The data are qualitative because they don't measure or count anything.
OB. The data are quantitative because they consist of counts or measurements.
OC. The data are qualitative because they consist of counts or measurements.
OD. The data are quantitative because they don't measure or count anything.

Answers

The given data is qualitative in nature because they do not measure or count anything.

According to the question,

We have the following information:

The blood groups are A, B, AB and O.

Now, we have to find whether this data is qualitative or quantitative in nature.

First, we will first find the definitions of qualitative data and quantitative data. Qualitative data means that the data describes the types, names, symbols or the nature of the objects being studies. It is often the nature of observation that is described in these types of data. For example, if one is studying endangered species then the reasons for their decline is qualitative data.

Quantitative data often gives us the numbers or the count of the object.

Now, in this case, we are not given that there are 4 different blood groups. Instead, we are given the types of blood groups.

So, this is qualitative in nature.

Hence, the correct option is A.

According to Descartes's rule of sign, how many possible positive and negative roots are there for the equation 0=-4x^6 - 3x^5+2x² - 4x +1? Drag the choices to the boxes to correctly complete the table.

Answers

[tex] -4x^6 - 3x^5+2x^2 - 4x +1 = 0[/tex] has 1 or 3 Positive roots and one only Negative roots.

Descartes' rule of sign.

Function has the same number of positive real zeroes as there are number of changes in the sign of the coefficients, or an even number less than the found number.

Now, here the given expression is : p(x) = [tex] -4x^6 - 3x^5+2x^2 - 4x +1 [/tex]

Now here, the number of sign changes are:

First : + to - in [tex] - 3x^5 => + 2x^2 [/tex]

Second : - to + in [tex]+2x² => - 4x [/tex]

Third: + to - in [tex] - 4x => +1 [/tex]

So, the total sign changes = 3

⇒ The total positive roots of p(x) = 3 or a EVEN NUMBER LESS THAN 3 = 1.

So, p(x) has either 3 or 1 POSITIVE ROOTS.

⇒ The number of negative roots p(x) has is either 4 or 6.

Hence has 1 or 3 Positive roots.

Now I look at f (−x). That is, having changed the sign on x, I'm now doing the negative-root case:

p(-x) = [tex] -4(-x)^6 - 3(-x)^5+2(-x)^2 - 4(-x) +1 [/tex]

= [tex] -4x^6 + 3x^5+2x^2 + 4x + 1 [/tex]

the number of sign changes are:

First : + to - in [tex] -4x^6 => +3x^5 [/tex]

So, the total sign changes = 1.

so there is exactly one negative root. (In this case, I don't try to count down by two's, because the first subtraction would give me a negative number.)

Hence has 1 or 3 Positive roots and one only Negative roots.

What's the length of PS, QS, and area of PQR?

Answers

First, notice the following right triangle that we can get with the vertices Q,S and P:

then, we can find PS and QS using the trigonometric functions sine and cosine:

[tex]\begin{gathered} \sin (62.58)=\frac{\text{opposite side}}{hypotenuse}=\frac{PS}{4.5} \\ \Rightarrow PS=4.5\cdot\sin (62.58)=3.99 \\ \cos (62.58)=\frac{\text{adjacent side}}{hypotenuse}=\frac{QS}{4.5} \\ \Rightarrow QS=4.5\cdot\cos (62.58)=2.07 \end{gathered}[/tex]

therefore, PS = 3.99 and QS = 2.07

Now, notice that the base of the triangle PQR is:

[tex]QR=QS+SR[/tex]

since we already know that SR = 5, we have that the base of the triangle is:

[tex]QR=2.07+5=7.07[/tex]

Now we can find the area of the triangle PQR:

[tex]A_{\Delta\text{PQR}}=\frac{\text{base}\cdot\text{height}}{2}=\frac{QR\cdot PS}{2}=\frac{7.07\cdot3.99}{2}=\frac{28.21}{2}=14.11[/tex]

what is the answer to 13 /5/6 - 17 /3/8

Answers

When the fractions, 13 5/6 and 17 3/8 are subtracted, the answer would be -3 ⁵ / ₁₂

How to subtract mixed fractions?

To subtract mixed fractions, the first thing to do is to convert the mixed fraction to an improper fraction.

To convert improper fractions, multiply the denominator by the whole number and then add the numerator. The result would be the numerator.

Converting the fractions gives:

13 5/6 = 83 / 6

17 3/8 = 139 / 8

Subtracting these fractions then gives:

= 83 / 6 - 139 / 8

Find a common denominator for 6 and 8 which will be 24 as this is their lowest common multiple.

Then, divide 24 by the denominator and multiply the result by the numerator of the fraction:

= 332 / 24 - 417 / 24

= -85 / 24

= - 3¹⁰ /₂₄

= -3 ⁵ / ₁₂

Write the point slope form of the equation of a line passing through (-1,4) and (-4,2)

Answers

The equation of a line in the point slope form is expressed as

y - y1 = m(x - x1)

Where

m represents slope

y1 represents intial value of y

x1 represents initial value of x

The formula for determining slope is expressed as

m = (y2 - y1)/(x2 - x1)

y2 and x2 are final values of y and x respectively.

From the information given,

x1 = - 1, x2 = - 4

y1 = 4, y2 = 2

Slope = (2 - 4)/(- 4 - - 1)

Slope = - 2/ (- 4 + 1)

Slope = - 2/- 3

m = 2/3

Substituting m = 2/3, y1 = 4 and x1 = - 1 into the point slope equation, it becomes

y - 4 = 2/3(x - - 1)

= y - 4 = 2/3(x + 1)

A chemical company makes two brands of antifreeze. The first brand is 30% pure antifreeze, and the second brand is 55% pure antifreeze. In order to obtain 60 gallons of a mixture that contains 45% pure antifreeze, how many gallons of each brand of antifreeze must be used?

Answers

36 gallons of the 55% brand and 24 gallons of the 30% brand of antifreeze must be used.

What is the percentage?

The percentage is defined as a ratio expressed as a fraction of 100.

Let x denote the amount of 30% pure antifreeze required in the combination.

The quantity of the 55% brand is then calculated (60-x).

The pure antifreeze content of the combination as:

⇒ 0.30x +0.30(60 -x) = 0.45 (60)

When we subtract 0.30(60), we get

x(0.55 -0.30) = 60(0.45 -0.30)

To simplify, divide by the coefficient

x = 9/0.25 = 36 .

Therefore, 36 gallons of the 55% brand and 24 gallons of the 30% brand of antifreeze must be used.

A dairy farmer wants to mix a 80 % protein supplement and a standard 70 % protein ration to make 1500 pounds of a high-grade 75 % protein ration. How many pounds of each should he use?

Answers

80% of protein supplement mixed with 70% of protein ration to make 1500 pounds of high grade 75% protein ration

so, let the number of pounds from 80% = x

And the number of pounds from 70% = y

Total pounds = 1500 pounds

so, x + y = 1500

The total concentration = 75%

so,

0.8 x + 0.7 y = 0.75 * 1500

So, the system of equations will be:

x + y = 1500 (1)

0.8 x + 0.7 y = 1125 (2)

solve the equations to find x and y

So,

Multiply the first equation by -0.7

-0.7 x - 0.7 y = -0.7 * 1500

-0.7 x - 0.7 y = -1050 (3)

Add the equations (2) and (3)

(0.8 x + 0.7y) + ( -0.7x - 0.7y ) = -1050 + 1125

0.8 x - 0.7 x + 0.7 y - 0.7 y = 75

0.1 x = 75

divide both sides by 0.1

x = 75/0.1 = 750

Substitute with x at the equation (1)

750 + y = 1500

y = 1500 - 750 = 750

so, the number of pounds from 70% = 750 pounds

The image of the point after the rotation is (-5, 7)

What is a 270 degrees rotation?

A 270 degrees rotation is a rotation that has the same effect as the 90 degrees counterclockwise of a figure.

How to determine the image of the rotation?

The coordinate of the point is given as

H = (-7, 5)

The rotation is given as 270° clockwise

As mentioned above,

The algebraic rule of its rotation to be changed from (x, y) to (-y, x) i.e. (x, y) => (-y, x)

So, we have

(x, y) => (-y, x)

Substitute (-7, 5) in (x, y) => (-y, x)

So, we have

(-7, 5) => (-5, 7)

Rewrite as

H' =(-5, 7)

Hence, the coordinates of the image using the rotation rule is (-5, 7)
