Answer:

400 students, 1/8 are left handed

Step-by-step explanation:

The slope or gradient of a line is a number that describes both the direction and the steepness of line. The equation in point slope form if (-1,2) is a point on the line and 1/4 is the slope is y-2=[tex]\frac{1}{4}x+\frac{1}{4}[/tex].

A number that identifies the direction and steepness of a line is its slope or gradient. Letter m is frequently used to represent the slope.

The ratio of "vertical change" to "horizontal change" between (any) two unique points on a line is used to compute slope. Occasionally, the ratio is written as a quotient (also known as a "rise over run"), which produces the same number for every two unique points on the same line. A declining line has a negative "rise." The line might be useful, as determined by a road surveyor, or it might appear in a diagram that represents a road or a roof as a description or a design.

Given,

x1= -1

y1= 2

slope= 1/4

Substituting the values in the equation,

y-y1= m(x-x1)

y-2= [tex]\frac{1}{4}[/tex](x+1)

y-2= [tex]\frac{1}{4}x+\frac{1}{4}[/tex]

By using dimensional analysis we find the following two results:

a) 0.30 m = 0.984 ft

b) 150 km / h = 1.554 mi / h

In this problem we must find a quantity of a given unit that is equivalent to another value of another unit of the same kind. For instance, we must look up for the quantity in a unit length equivalent to another quantity in another unit length. Now we proceed to obtain all the equivalencies by simple rule of three:

a) 0.30 m × (1 ft / 0.3048 m) = 0.984 ft

b) 150 km / h × (1 mi / 1.609 km) × (1 h / 60 min) = 1.554 mi / h

Answer: it would be 18/3 or

Step-by-step explanation:

2/3 x 9 = ?

1) You multiple both numerator and denominator: 2x9 / 3x1 = 18/3

2) Find the GCF ( greatest common factor) for both numbers. Which is

3) Then divide both the numerator and denominator by 3 to simplify to it's lowest term: 18÷3= 6 and 3÷3= 1 which gives a fraction of 6/1 or

The number that has a 6 that is 1/10 the value of the 6 in 527.6 is B. 982.46.

It should be noted that we are to simply find the place value of the numbers.

In 527.6, the place value is 1/10.

On the other hand, in 982.46, the place value is 1/100.

Therefore, the number that has a 6 that is 1/10 the value of the 6 in 527.6 is 982.46.

Answer:

2(w+11w)=1680

Step-by-step explanation:

If the width is w, then the length is 11w.

Using the formula for the perimeter of the rectangle, the equation is 2(w+11w)=1680

       The range is all the y-value or outputs of a function. In the case of a horizontal line, this is only one value.

               The range is the y-intercept, -5.

       The domain is all x-values or inputs of a function. For this graph, it is all real numbers (as you said).

               The domain is all real numbers.

Answer:

[0, 8)

Step-by-step explanation:

To find the range, compute the values of the function at the edges of the interval.

The interval edges are -1 and 3

f(x = -1)  = (-1)² - 1 = 1 - 1 = 0.

f(x = 3) = 3² - 1 = 9 - 1 = 8   but does not include 3 so

so range of f(x) : 0  ≤ f(x) < 8

Note that we cannot have f(x) ≤ 8 only < 8 since the interval does not include x = 3

Range in interval notation is [0, 8)

The use of the square brackets on the left means the number is included in the interval; so 0 is included ( ≥ ).

The round brackets on the right mean that the number is not include (< 8 )

Step-by-step explanation:

hmmm, it is all there, you only need to write it up.

so, please, let me know what you don't understand about such equations and variables.

(a)

2x + 5y = 45

8x + 3y = 44

(b)

to solve this we try to use either one equation to express one variable by the other. and solve for that remaining variable (and then drive the second one from that), or to combine both equations directly to eliminate one variable and solve.

I think the second option is best here.

so, we multiply the 1st equation by -4, and then we add both equations :

-8x - 20y = -180

8x + 3y = 44

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

0 - 17y = -136

-17y = -136

17y = 136

y = 8

2x + 5y = 45

2x + 5×8 = 45

2x + 40 = 45

2x = 5

x = 2.5

A set with an infinite number of elements is one that cannot be numbered. A set that has no last element is said to be endless. A set that can be put into a one-to-one correspondence with a suitable subset of itself is said to be infinite. No issue with the in-class assignment.

The stars in the clear night sky, water droplets, and the billions of cells in the human body are just a few examples of endless sets of objects that surround us. A set of natural numbers, however, serves as the best illustration of an infinite set in mathematics. There is no limit to the amount of natural numbers.

The solution of the simultaneous equations is given by: x=0.60 and

y = 0.80 .

A system of equations or simultaneous equations, usually referred to as an equation system, is a collection of finite equations for which common solutions are sought.

The given pair of simultaneous equations are:

6 x + 8 y = 10

9 x + 6 y = 10.20

Now let us multiply the first equation by 6 and the second equation by 8 and subtract it from the first.

   36 x + 48 y = 60

   72 x + 48 y = 81.60

⇒ 36 x  = 21.60

⇒ x = 21.60 ÷ 36

⇒ x = 0.60

Substituting the value in the first equation we get:

y= 0.80.

Hence the solution of the simultaneous equation is x=0.60 and

y = 0.80 .

Using the OR and AND operations, we have that:

a. The graph of the and operation is x > a, while the graph of the or operation is x > b.

b. The graph of the and operation is x > b, while the graph of the or operation is x > a.

c. The graphs of both operations are the same, given by x > a = x > b.

The result of the AND operation between two data-set is the set that contains elements that belong to both sets.

The result of the OR operation between two data-set is the set that contains elements that belong to at least one of the sets.

In item a, we have that a is to the right of b, hence:

Hence:

The graph of the and operation is x > a, while the graph of the or operation is x > b.

In item b, we have that a is to the left of b, hence:

Hence:

The graph of the and operation is x > b, while the graph of the or operation is x > a.

In item c, we have that a and b are the same point, hence, hence the graphs of both operations are the same, given by x > a = x > b.

The domain is all real numbers.

The initial value is 3.

The simplified base is 3√2.

A function is an expression that illustrates the connection between two or more variables and numbers. A function defined by several subfunctions, each of which is applicable to a distinct interval in the domain, is said to be piecewise.

We have function,

f(x) = 3√18 x

now, simplifying the function we get

f(x) = 3 (3√2)x
