Using the percentage and hours, the total number of technician that was there is 42.

The project is budgeted for 2400 hours and will last 3 weeks.

This means the whole project will last for 2400 hours for 3 weeks.

Technicians will cover 25% of the project for the first week and then 60% for the final two weeks.

This simply implies 25% of the project will be completed in the first week. Then 60% of the remainder of the project will be completed the final two weeks.

Each technician normally works 40 hours per week.

Therefore,

Number of hours for the first week = 25 % of 2400

Number of hours for the first week = 25 / 100 × 2400

Number of hours for the first week = 600 hours

Therefore,

number of technicians for the first week = 600 / 40

number of technicians for the first week = 15 technicians

Therefore,

Number of hours for the final two week = 60 % of (2400 - 600)

Number of hours for the final two week = 60 / 100 × 1800

Number of hours for the final two week = 1080 hours

Hence,

number of technicians for the final two week = 1080 / 40

number of technicians for the final two week = 27 technicians

Therefore, the total number of technician that was there is 42.

The slope of the two equations is required to answer this

What is an equation?

An equation is a formula in mathematics that expresses the equality of two expressions by linking them with the equals sign. The word equation and its cognates in various languages may have somewhat different definitions; for example, in French, an équation is defined as including one or more variables, but in English, an equation is any well-formed formula consisting of two expressions linked by an equals sign.

Given equation

[tex]y=x+1[/tex] has slope [tex]m1=1[/tex]

and the other equation

[tex]-\frac{6}{5}x+3[/tex] has slope [tex]m2 =-\frac{6}{5}[/tex]

Yes, it should be that.Giovanni's account balance has the least variation from maximum to minimum that month.

It should be noted that the formula for calculating the variation is;

Balance difference  = Maximum balance - Minimum balance.

For Jordan;

Maximum balance = $145.

Minimum balance = $-25

Balance difference  = 145 - (-25) = $170

For Giovanni;

Maximum balance = $168.

Minimum balance = $15.

Balance difference  = 168 - 15 = $ 153.

For Elisa;

Maximum balance = $152.

Minimum balance = $-10

Balance difference  = 152 -(-10) = $162.

Therefore, for the data it is clear that the minimum account variation is for Giovanni which is $153.

Evaluate 1(8+12)-4)+5. (6-3)​ = 31

Solution :

PEMDAS rule states that the order of operation starts with the parentheses first or the calculation which is enclosed in brackets. Then the operation is performed on exponents (degree or square roots) and later we do operations on multiplication & division and at last addition and subtraction.

BODMAS, BIDMAS and PEMDAS are acronyms for remembering the order of operations in mathematics. BODMAS stands for Brackets, Orders, Division, Multiplication, Addition and Subtraction. BIDMAS and PEMDAS do exactly the same thing but using different words.

MDAS :

stands for Multiplication, Division, Addition, and Subtraction. It is part of the Order of Operations, a collection of rules that gives a sequence for simplifying mathematical operations. It is used when an expression or equation has more than one operation. According to the Order of Operations, all multiplication or division must occur before addition or subtraction. For example, the expression 6+4×5 involves addition and multiplication. According to MDAS, simplify the multiplication portion of the expression before adding. Since 4×5 equals 20, rewrite the expression as 6+20, which equals 26

The given parameters are:

Rewrite the parameters properly as:

Diameter of pizza = 10 +1/3 inches

Length of square box =  10.38 inches

So, we have:

Diameter of pizza = 10 + 1/3 inches

Evaluate the sum

Diameter of pizza = 10.33 inches

The time taken to walk from first floor to sixth floor at same pace, assuming

all floors have the same height is 318 seconds or 5 minutes 18 seconds.

It takes you 53 seconds to walk from the first​ (ground) floor of a building to the third floor.

There are 60 seconds in every minute, so converting seconds to minutes is simple. Just divide the number of seconds by 60 to get your answer. Every 60 seconds a full minute has passed. Dividing a number tells you how many times one number "fits" in the other. Oftentimes the number of seconds will not perfectly convert into minutes. This decimal represents the number of seconds left over.

Walking one floor takes 53 seconds.

So, walking six floors at same pace = 53 seconds * 6

=> 318 seconds or 5 minutes 18 seconds.

A stem-and-leaf plot is a table that is used to display numbers. It is similar to a histogram. A stem-and-leaf plot divides a number into a stem and a leaf. The stem is the first number in the digit while the leaf is the last number. For example in the number 21, 2 would be the stem and 1 would be the leaf.

An advantage of the stem-and-leaf plot is that all the data in the data set are shown. A drawback of a stem-and-leaf plot is that it can only be used for a small dataset.

Looking at the stem-and-leaf plot, it can be seen that the professors in their 40s have the highest frequency. They are 14 professors in their 40s.

Option c - (0 , -1).

Terminal Point on the Unit Circle. To find the terminal point on the unit circle, start at (1, 0), measure the angle in degree or radian on the circle (move counter clockwise if the angle is positive and clockwise if the angle is negative.) The coordinate of the endpoint is called the terminal point.

In a unit circle, θ = 3π/2 radians.

r = 1

Angle θ = 3π/2

The terminal point is (rcosθ, rsinθ)

= (cos3π/2, sin3π/2)

cos3π/2 = 0

sin3π/2 = -1

= (0, -1)

Thus,  for the unit circle 3π/2 = 0  ,the terminal points are (0, -1) . So the option C is the correct answer.

The equation of the curve is [tex]y=x^{3}-2x^{2}+5x+1[/tex].

The Gradient of the curve at a point is defined as the gradient of the tangent to the curve at that point. To find the gradient at a particular point on the curve y=f(x), simply substitute the x -coordinate of that point into the derivative.

Given the gradient of a curve at a point P(2,11) is 9.

[tex]\frac{d^{2}y }{dx^{2} } =6x-4[/tex]

Integrating both sides-

[tex]\frac{dy}{dx } =\frac{6x^{2} }{2}-4x+C[/tex]

[tex]\frac{dy}{dx } =3x^{2} -4x+C[/tex]

Now, the gradient of a curve at a point P(2,11) is 9.

⇒[tex]3(2^{2})-4(2)+C=9[/tex]

⇒4+C=9

⇒C=5

So, [tex]\frac{dy}{dx } =3x^{2} -4x+5[/tex]

Again integrating both sides-

[tex]y=x^{3}-2x^{2} +5x+A[/tex]

Point(2,11) lies on the curve.

So, [tex]11=2^{3}-2(2^{2}) +5(2)+A[/tex]

⇒11=10+A

⇒A=1

Putting value of A in equation of curve-

[tex]y=x^{3}-2x^{2}+5x+1[/tex].

Thus, The equation of the curve is [tex]y=x^{3}-2x^{2}+5x+1[/tex].
