Answers

Answer 1

The cost of one hamburger and one hot dog = $10.4 and $7.25.

What is a linear equation?

a connection between two or more factors that results in a linear model when displayed on a graph. The variable will have a degree of one.

Y = mx + c is the linear equation.

where the line's y-intercept is represented by c and its m-slope by a slope.

x + y = 17.65                     ...(1)

22x + 39y = 511.55          ...(2)

22(17.65 - y) + 39y = 511.55

388.3 - 22y + 39y = 511.55

17y = 123.25

y = $7.25

x + 7.25 = 17.65

x = 17.65 - 7.25

x = $10.40

The cost of the hamburger and hot dog will be $10.4 and $7.25

Given expression( function )

[tex]h(x) = \frac{12}{2x} + 16[/tex]

Thus, plug in -8 in the variable x and solve as follows:-

[tex]h( - 8) = \frac{12}{2( - 8)} + 16[/tex]

Multiply the numbers 2.(-8) = -16

[tex] = \frac{12}{ - 16} [/tex]

which of the following is an advantage of a cumulative frequency polygon over a histogram or frequency polygon?

Answers

An advantage of a cumulative frequency polygon over a histogram or frequency polygon is that: it can directly compare two or more frequency distributions.

What is a cumulative frequency polygon?A sort of frequency polygon that displays cumulative frequencies is called a cumulative frequency polygon. In other words, the graph adds the cumulative percentages from left to right. On a cumulative frequency polygon's graph, class boundaries are shown along the x-axis and cumulative frequency is shown on the y-axis.

Now,

Two alternative methods of graphically presenting data given in the form of a frequency distribution are frequency polygons and histograms. While a histogram can only be created for grouped frequency distribution, the frequency polygon can represent both grouped and ungrouped (discrete) data.Since it is easier to compare the frequencies in cumulative frequency polygon as compared to these two, the former has an advantage over the latter.

The quotient of the quantity (30 × 10⁻²⁴)/(5 × 10⁻²⁴)  is found out to be 6 × 10⁰.

What is meant by scientific notation?

For writing exceptionally large or extremely small numbers, scientific notation is comparable to shorthand. A process is limited to a number multiplied by ten rather than written in decimal form.

In a mathematical equation, the "coefficient" is the first number. The coefficient must be less than ten and greater than one. For example, the coefficient for developing scientific notation for the number 256 is 2.56.As in the equation, the second number is a power of ten, presented as a power of ten with just an exponent, such as 10², which stands for 10 x 10.

Now, as per the expressed equitation;

= (30 × 10⁻²⁴)/(5 × 10⁻²⁴)

Divide the numerator (30 × 10⁻²⁴) by denominator (5 × 10⁻²⁴) by the quotient.

= 6 × 10⁰

A circle is a two-dimensional closed figure in which the set of all points with in plane is equidistant from the a given point known as the "centre."

Circle Formula: (x - h)² + (y - k)² = r² ;

Where, (h, k) is the centre & r is the radius of the circle.

Use the distance formula for(-2, 1) and (0,2)

[tex]\begin{aligned}&r=\sqrt{\left(x_2-x_1\right)^2+\left(y_2-y_1\right)^2} \\&r=\sqrt{(0+2)^2+\left(2-1\right)^2} \\&r=\sqrt{(2)^2+\left(1\right)^2}\end{aligned}[/tex]

Further simplifying;

r = √(4 + 1)

r = √5

Centre (h, k) = (-2, 1)   Radius (r) = √5.

(x - h)² + (y - k)² = r²

(x + 2)² + (y - 1)² = √5²
