What is the solution to the system of equations y 1. 5x 4 y =- X?.

The equation of the regression line is y = 0.430x + 3.59.

A characteristic of the data that is ignored by the regression line is that: A. The data has a pattern that is not a straight line.

In order to determine a linear equation for the regression line (trend line) that models the data points contained in the table, we would have to use a graphing calculator (scatterplot).

In this scenario, the x-values would be plotted on the x-axis of the scatterplot while the y-values would be plotted on the y-axis of the scatterplot.

On the Excel worksheet, you should right click on any of the data point on the scatterplot, select format trend line, and then tick the box to display an equation for the regression line (trend line) on the scatter plot.

By critically observing the scatterplot (see attachment) which models the relationship between the x-values and y-values, a linear equation for the regression line (trend line) is given by:

y = 0.430x + 3.59

2. Critical numbers of a function h(t) = t^(3/4) - 3t^(1/4) are (1/16 , -1/16).

A number is critical if it makes the derivative of the expression equal 0.

Critical numbers are values of a function where the function's tangent lines are either horizontal or vertical.

Given function is,

h(t) = t^(3/4) - 3t(1/4)

We have to find critical points.

For this we will take derivative and set it with 0

Therefore

h'(t) = (3/4)t^(-1/4) - 3(1/4)t^(-3/4) = 0

3/4[t^(1/4)] = 3/4[t^(3/4)]

4t^(3/4) = t^(1/4)

4 = 1/√t

t = 1/16 and t= -1/16.

Therefore critical points are (1/16 , -1/16).

a) The 90% confidence interval for the average salary of an entry-level computer engineer is of: (16.28, 83.72).

b) The sample contains the value 80, hence it does not give sufficient evidence that the average salary of all entry-level computer engineers is different from $80,000.

c) The 90% confidence interval for the standard deviation of entry level salaries is of: (6.67, 389.86).

The bounds of the confidence interval are given according to the following rule:

[tex]\overline{x} \pm t\frac{s}{\sqrt{n}}[/tex]

In which the variables of the equation are presented as follows:

The sample in this problem is given as follows:

30, 50, 70.

Hence the values of the parameters are given as follows:

[tex]\overline{x} = 50, s = 20, n = 3[/tex]

The critical value, using a t-distribution calculator, for a two-tailed 90% confidence interval, with 3 - 1 = 2 df, is t = 2.92.

Then the lower bound of the interval is of:

[tex]\overline{x} - t\frac{s}{\sqrt{n}} = 50 - 2.92\frac{20}{\sqrt{3}} = 16.28[/tex]

The upper bound of the interval is of:

[tex]\overline{x} + t\frac{s}{\sqrt{n}} = 50 + 2.92\frac{20}{\sqrt{3}} = 83.72[/tex]

The bounds of the confidence interval for the standard deviation are given as follows:

[tex]\frac{(n - 1)s^2}{\chi^2_\frac{\alpha}{2}} \leq \sigma \leq \frac{(n - 1)s^2}{\chi^2_{1 - \frac{\alpha}{2}}}[/tex]

The critical values of the chi-square distribution with a confidence level of 90% and 2 df are given as follows:

[tex]\chi^2 = 0.1026, \chi^2 = 5.9915[/tex]

Hence the lower bound of the interval is of:

2 x 20/5.9915 = 6.67.

Sydney will spend $19.48 on fruit.

Price of strawberries = $1.68 per pound

Price of raspberries = $2.98 per pound

Sydney wants to buy 8.4 pounds of strawberries and 1.8 pounds of raspberries.

Therefore,

Price of 8.4 pounds strawberries = 8.4*Price per pound

Price of 8.4 pounds strawberries = 8.4*1.68 = $14.112

Price of 1.8 pounds raspberries = 1.8*price per pound

Price of 1.8 pounds raspberries = 1.8*2.98 = $5.364

Total spent on fruit = Price of 8.4 pounds strawberries + Price of 1.8 pounds raspberries

Total spent on fruit = $14.112 + 5.364 = 19.48

The intermediate step  in the form ( x + a ) ^2 = b (x+a)  2 =b as a result of completing the square  of x² - 4x = 45 is (x- 2)² = 49

How to determine the intermediate step?

The equation is given as:

x² - 4x = 45

Take the coefficient of x

k = -4

Divide by 2

k/2 = -2

Square both sides

(k/2)^2 = 4

Add 4 to both sides of x² - 4x = 45

x² - 4x + 4= 45 + 4

This gives

x² - 4x + 4= 49

Express as perfect square

(x- 2)² = 49

The domain of the square root function is x≥0.

What is a function?

Any relation in which each input has exactly one output is referred to as a function. To put it another way, the function outputs one value exactly for each input value. Because one is mapped to two different values, the graph above depicts a relation rather than a function. But if one were instead mapped to a single value, the relation above would become a function. Furthermore, output values could be identical to input values.

The x-values are input into the function machine. The function machine then performs its operations and outputs the y-values. The function within can be any function.

The square root function's purpose must now be considered. The positive number that results in the input after being squared is returned as the principal root or output. Since y will be bigger than or equal to 0, we may be certain of that.

To find out a perfect square we need to find out square root is an integer.

(1,0,0), (0,1,0), (0,0,1) be standard basis of IR^3

Therefore T(1,0,0) = (1,0,0)

(1,0,0) is 1st column of matrix of T

T(0,1,0) = (1,1,0)

(1,1,0) is 2nd column of matrix of T

T(0,0,1) = (1,1,0)

(1,1,0) is 3rd column of matrix of T

Therefore Matrix representation of T with respect to standard basis of IR^3 is

A = 1,1,1    0,1,1    0,0,0

2. Nullspace of T = kennel T

KerT = {(x,y,z)E IR^3/T(x,y,z,) = (0,0,0)}

Range T = {(x+y+z)(1,0,0) + (y+z)(0,1,0)}

As range contains only two linear independent rectors = Rank = 2

consider basis, B = {(1,0,0), (1,1,0), (1,1,1)}

T(1,0,0) = (1,0,0)

(1,0,0) = a(1,0,0) + b(1,1,0) + c(1,1,1)

(1,0,0) = (a+b+c, b+c, c)

a+b+c = 1, b+c = 0, c = 0

b = 0, a = 1

Therefore above of a,b,c gives first column matrix

Now,

T(1,1,0) = (2,1,0)

consider (2,1,0) = a(1,0,0) + b(1,1,0) + c(1,1,1)

(2,1,0) =  (a+b+c, b+c, c)

a+b+c = 2, b+c = 1, c = 0

b = 1, a = 1

Therefore above values of a,b,c gives 2nd column of matrix

a+b+c = 3, b+c = 2, c = 0

b = 2, a = 1

We have given that,

parabola equation is y = 5x - 3x²

line passing through origin is in the form of y = mx

==> mx = 5x - 3x²

==> 3x²+ mx - 5x = 0

==> 3x² + x(m -5) = 0

==> x(3x + (m -5)) = 0

==> x = 0 , x = (5 -m)/3

The total area of the bounded region is then the integral of 5x - 3x² from x = 0 to x = (5-m)/3

Area under y = 5x - 3x2 and y = mx is (125/54)/2 = 125/108

==> [0 to (5 -m)/3] ∫(5x - 3x²-mx )dx = 125/108

==> [0 to (5 -m)/3]∫( (5 - m)x - 3x2 )dx = 125/108

==> [0 to (5 -m)/3] ((5 - m)x²/2 - x³ )= 125/108

==> (5 - m)[(5 -m)/3]²/2 - ((5 -m)/3)³ = 125/108

==> (5 -m)³/18 - (5 -m)³/27 = 125/108

==> (5 -m)³/54 = 125/108

==> (5 -m)³ = 125/2

==> (5 -m) = 3.9685

==> m = 5 - 3.9685

==> m = 1.0315

Hence slope of line = 1.0315

1)Normal dots are the set of data that has a normal distribution and a graph of your data can help to decide whether or not the data is normal. Making a histogram of the data can help to decide whether or not a set of data is normal, but a normal probability plot is more specialized: it graphs z-scores (normal scores) against the data set.

2)A scatterplot displays an association between two sets of data. A scatterplot can also be named a scattergram or a scatter diagram.

3)Equal variances are when the variances are roundabout the same across the samples. Unequal variances can change the error rate and lead to false positives.

Dot plots show the distribution of the data.

A dot plot is defined as a simple plot that displays data values as dots above a number line. Dot plots show the frequency with which a specific item appears in a data set and also shows the distribution of the data.

From the given dot plot, we can interpret the following parameters;

Number of students that spent 1 hour on homework = 1 person

Number of students that spent 2 hours on homework = 5 persons

Number of students that spent 3 hours on homework = 6 persons

Number of students that spent 4 hours on homework = 4 persons

Number of students that spent 5 hours on homework = 1 person

Number of students that spent 6 hours on homework = 1 person

Probability curve always give a probability of zero for a point estimate on a continuous random variable.

A probability distribution in which the random variable x can take on any value because there are infinite values that x could assume, the probability of x taking on any one specific value is zero.

we often speak in ranges of values (p(x>0) = .50). The normal distribution is one example of a continuous distribution. The probability that X falls between two values (a and b) equals the integral (area under the curve) from a to b.

Density function:

f(x) = P(a≤x≤b) = ∫f(x).dx ≥ 0.
