He is interested in studying the center, shape and spread of the data. He make histogram graph because it is the best since it demonstrates how the population is distributed.

A histogram is a graph that displays the frequency distribution of a small number of data points for a single variable. Frequently, histograms divide data into several "bins" or "range groups" and tally how many data points are in each bin.

A bar graph uses bars, columns, or strips to display facts, amounts, or numbers in a visual way.

To demonstrate how so much one factor influences others, scatter plots are used to display data points on the a vertical and horizontal axis.

A pie chart, also known as a circle chart, can be used to summarize a set of nominal data or to show the various values of a particular variable.

Jack will have $332 after 5 years

The formula for compound interest is:

A = P (1 + r/n)^(nt)

where:

A = the future value of the investment, including interest

P = the principal investment amount

r = the annual interest rate (decimal)

n = the number of times that interest is compounded per year

t = the number of years the money is invested/borrowed for

r = 2% = 0.02, P =  $300, n = 12 (12 times in a year), t = 5 years

A = P (1 + r/n)^(nt)

A = 300 (1 + 0.02/12)^(12*5)

A = 300 (1 + 0.02/12)^(60)

A = $332

The vector orthogonal to the plane through the points P, Q, and R is (8, -8, 12), and the area of triangle PQR is [tex]$\sqrt{301}$[/tex].

For part (a), we can find a nonzero vector orthogonal to the plane through the points P, Q, and R by constructing a normal vector to the plane using the cross product of two vectors in the plane. The two vectors in the plane are [tex]$\vec{PQ} = (1- (-2), 0-1, 1-3) = (3, -1, -2)$[/tex] and [tex]$\vec{PR} = (1-4, 0-2, 1-5) = (-3, -2, -4)$[/tex]. Taking the cross product of the two vectors gives us the normal vector to the plane, [tex]$\vec{n} = \vec{PQ} \times \vec{PR} = (8, -8, 12)$[/tex]. Therefore, the vector orthogonal to the plane is [tex]$\vec{n} = (8, -8, 12)$.[/tex]

For part (b), the area of triangle PQR can be found using the formula for Heron's Formula, which states that the area of a triangle with sides a, b,and c is given by

[tex]$A = \sqrt{s(s-a)(s-b)(s-c)}$[/tex]

where [tex]$s = \frac{a+b+c}{2}$[/tex] . In this case, the sides are [tex]$a = \|\vec{PQ}\| = \sqrt{3^2 + (-1)^2 + (-2)^2} = \sqrt{14}$, $b = \|\vec{QR}\| = \sqrt{(-2-4)^2 + (1-2)^2 + (3-5)^2} = \sqrt{14}$[/tex], and[tex]$c = \|\vec{PR}\| = \sqrt{(-3)^2 + (-2)^2 + (-4)^2} = \sqrt{29}$[/tex]. Plugging these values into the formula, we get

[tex]= \sqrt{s(s-a)(s-b)(s-c)} = \sqrt{\frac{7(7-\sqrt{14})(7-\sqrt{14})(7-\sqrt{29})}{4}} = \sqrt{7(7-\sqrt{14})^2(7-\sqrt{29})} = \sqrt{7(7-\sqrt{14})^2(\sqrt{14}+\sqrt{29})} = \sqrt{7(7-\sqrt{14})^2\sqrt{43}} = \sqrt{301}$[/tex]Therefore, the area of triangle PQR is [tex]$\sqrt{301}$[/tex]

Vertex of parabola = (-8 , -6)

Focus of parabola = (-8 , -23/4)

Directrix of parabola is y = -25/4

Axis of symmetry of parabola is x = -8

Direction of opening of parabola is vertically upwards.

y - intercept = 58 unit

A parabola refers to an equation of a curve, such that a point on the curve is equidistant from a fixed point, and a fixed line. The fixed point is called the focus of the parabola, and the fixed line is called the directrix of the parabola.

Given equation of parabola

y = x² + 16x + 58

It can be written as

y = x² + 16x + 64 - 6

y = (x + 8)² - 6

Comparing with standard vertex form

y = a(x - h)² + k

Vertex (h, k) = (-8 , -6), a = 1

a = 1/4(f - k)

1 = 1/4(f - -6)

4f + 24 = 1

f = -23/4

Focus (h , f) = (-8 , -23/4)

Directrix is y = d

Distance from the focus to the vertex is the same as the distance from the vertex to the directrix.

-6 - (-23/4) = d - (-6)

d = -6 -6 + 23/4

d = -12 + 23/4

d = -25/4

Directrix is y = -25/4

The axis of symmetry is the line perpendicular to the directrix that passes through the vertex and the focus:

x = -8

Direction of opening will be vertically upwards

For y-intercept, x = 0

y = (0 + 8)² - 6

y = 64 - 6

y = 58

Hence, (-8 , -6) is Vertex of parabola

(-8 , -23/4) is Focus of parabola

y = -25/4 is Directrix of parabola

x = -8 is Axis of symmetry of parabola

Direction of opening of parabola is vertically upwards.

The system of equations have no solutions as they are parallel lines

The equation of a line is expressed as y = mx + b where m is the slope and b is the y-intercept

And y - y₁ = m ( x - x₁ )

y = y-coordinate of second point

y₁ = y-coordinate of point one

m = slope

x = x-coordinate of second point

x₁ = x-coordinate of point one

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

Given data ,

Let the equation of first line be A

Let the equation of second line be B

Let the first point be P ( 0 , 3 )

Let the second point be Q ( 3 , 4 )

Now , the slope of the line is m = ( y₂ - y₁ ) / ( x₂ - x₁ )

Substituting the values in the equation , we get

Slope m = ( 4 - 3 ) / ( 3 - 0 )

Slope m = 1/3

Now , the equation of line A is

y - y₁ = m ( x - x₁ )

y - 3 = ( 1/3 ) ( x - 0 )

y - 3 = ( 1/3 )x

Adding 3 on both sides of the equation , we get

y = ( 1/3 )x + 3   be equation (1)

And , the third point is R ( 0 , -2 )

Let the fourth point be S ( 3 , -1 )

Now , the slope of the line is m = ( y₂ - y₁ ) / ( x₂ - x₁ )

Substituting the values in the equation , we get

Slope m = ( -1 - ( -2 ) ) / ( 3 - 0 )

Slope m = 1/3

Now , the equation of line A is

y - y₁ = m ( x - x₁ )

y - ( -2 ) = ( 1/3 ) ( x - 0 )

y + 2 = ( 1/3 )x

Subtracting 2 on both sides of the equation , we get

The size of a sample is related to the spread of the sampling distribution in that the larger the sample size, the less the spread.

As the sample size increases, the sampling distribution of p becomes increasingly concentrated around the true population proportion p. This is because, as the sample size increases, the number of possible random samples of size n becomes larger, making it more likely that the observed sample proportion will be close to the true population proportion.

The mean of the sampling distribution of p is p, which is the true population proportion. The standard deviation of the sampling distribution of p (σp) can be calculated using the formula:

σp = √((p)(1-p))/n

where p is the true population proportion and n is the sample size. This standard deviation indicates how closely the sample proportion is likely to match the true population proportion. The smaller the standard deviation, the more closely the observed sample proportion is likely to match the true population proportion.
