Answer:

Area = 8 sq cm

Step-by-step explanation:

This shape is a parallelogram. Its like a rectangle that got tipped over. Area is:

base × height.

We don't know the base that is on the bottom of the image as it is shown. But if you turn it sideways, the 4 can be the base and the 2 is the height.

Area = b × h

= 4 × 2

= 8

The area is 8 sq cm.

Yes, the triangle with the given side lengths exists because the triangle inequality holds true.

At first, students might think that the lengths of the sides of a triangle can be any three lengths, but that is not so. The triangle inequality says that the length of any side must be less than the sum of the lengths of the other two sides.

We are given a set of three side lengths. The side lengths are 3, 4, and 5. We need to check whether a triangle can be formed using the given three side lengths. We will use the triangle inequality.

The first inequality is 3 + 4 > 5. This inequality holds true because 7 is greater than 5. The second inequality is 4 + 5 > 3. This inequality holds true because 9 is greater than 3. The first inequality is 5 + 3 > 4. This inequality holds true because 8 is greater than 4. The triangle inequality holds true, so a triangle with the given side lengths exists.

The lower limit of the 95% confidence interval for the average miles per gallon is 23.32 mpg.

How to calculate the lower limit of the confidence interval?

Given,

n = 30

mean = μ = 24.1

standard deviation = σ = 2.1

confidence interval = 95%

Since the sample is 30, use t-table. If sample is greater than 30 use z-table.

Level of significance, α = 1 - 0.95 = 0.05

degree of freedom, df = n - 1 = 30 - 1 = 29

t value = 2.045

Lower limit = [tex]\mu-t\frac{s}{\sqrt{n}}[/tex]

= [tex]24.1 - 2.045\frac{2.1}{\sqrt{30}}[/tex]

= 24.1 - 0.784

= 23.316

= 23.32 mpg

Thus, the lower limit of the 95% confidence interval for the average miles per gallon is 23.32 mpg.

b. The graph is given by the image at the end of the answer, and the vertices are (4,4), (10,4) and (10,7).

c. The number of clay beads and glass beads in a necklace that costs the least to make is: 4 clay beads and 4 glass beads.

The variables for the system are presented as follows:

Each necklace has no more than 10 clay beads and at least 4 glass beads, hence the constraints are listed as follows:

The numbers of each beads are countable amounts, meaning that they cannot assume negative values.

Four times the number of glass beads is less than or equal to 8 more than twice the number of clay beads, hence the final constraint is of:

4y ≤ 8 + 2x.

Each clay bead costs $0.20 and each glass bead costs $0.40, hence the cost function is given as follows:

C(x,y) = 0.2x + 0.4y.

Using the three constraints, the graph is given by the image at the end of the answer, and the vertices are as follows:

The minimum cost is at the vertex with the smallest numeric value of the cost function, hence the numeric values are listed as follows:

Answer:

[tex]y = 2x - 5[/tex]

Step-by-step explanation:

The first step in finding the equation of a line from a given set of points is to find its slope. The slope of a line is defined by the formula:

[tex]m = \dfrac{\textrm{rise}}{\textrm{run}} = \dfrac{y_2 - y_1}{x_2 - x_1}[/tex]

In this problem, we are given two points in the form [tex](x_1, y_1)[/tex] and [tex](x_2, y_2)[/tex].

So, we can define the x's and y's as:

[tex]x_1 = 3[/tex], [tex]y_1 = 1[/tex], [tex]x_2 = 1[/tex], [tex]y_2 = -3[/tex].

Hence, the slope of the line can be solved for.

[tex]m = \dfrac{-3 - 1}{1 - 3}[/tex]

[tex]m=\dfrac{-4}{-2}[/tex]

[tex]m = 2[/tex]

So, the slope of the line is 2.

Now, we can plug this into the point-slope equation for a line where (a, b) is a point on the line and m is its slope.

[tex]y - b = m(x - a)[/tex]

I will use the point (3, 1):

[tex]y - 1 = 2(x - 3)[/tex]

and isolate y to put it into slope-intercept form.

[tex]y - 1 = 2x - 6[/tex]

[tex]y = 2x - 6 + 1[/tex]

[tex]y = 2x - 5[/tex]

So, the equation in slope-intercept form for the line that goes through the points (3, 1) and (1, -3) is [tex]y = 2x - 5[/tex].

The equation of the line that passes through (-1, -1) and is parallel to x + y = 8 is x + y = -2

The equation of the line that passes through (-5, -2) and is parallel to y + 3x = 10 is 3x + y = -17

From the question, we are to determine the equation of the line passing through the given points and parallel to the given line.

NOTE: If two lines are parallel, then their slopes are equal

First, we will determine the slopes of the given line

x + y = 8

Write the equation in the slope-intercept form, y = mx + b

Where m is the slope

and b is the y-intercept

x + y = 8 becomes

y = -x + 8

Therefore, m = -1

Now, we will determine the equation of a line that has a slope of -1 and that passes through (-1, -1)

Using the point-slope form of the equation of a straight line,

y - y₁ = m(x - x₁)

y - (-1) = -1(x - (-1))

y + 1 = -1(x + 1)

y + 1 = -x -1

x + y = -1 -1

x + y = -2

Hence, the equation is x + y = -2

Now, we will determine the slope of y + 3x = 10

Express the equation in slope-intercept form

y + 3x = 10

y = -3x + 10

Therefore, m = -3

Now, we will determine the equation of a line that has a slope of -3 and that passes through (-5, -2)

Using the point-slope form of the equation of a straight line,

y - y₁ = m(x - x₁)

y - (-2) = -3(x - (-5))

y + 2 = -3(x + 5)

y + 2 = -3x - 15

3x + y = -15 -2

3x + y = -17

The equation for the line that runs between the points (8, 4) and (0, 2) has the following slope-intercept form is : y = 1/4 x + 2

The point-slope form, standard form, and slope-intercept form are the three main types of linear equations.

Here,

A line's equation can be written as y = mx + b in slope-intercept form.

slope = m and y-intercept = b.

You can rewrite the equation in point-slope form as y = mx + b.

Given,

y - 4 = 1/4 (x - 8)

Change the formula to y = mx + b.

So,

y - 4 = 1/4 x - 2

We have to add 4 on both sides,

y - 4 + 4 = 1/4 x - 2 + 4

y = 1/4 x + 2

As a result, the equation of the line passing through the points (8, 4) and (0, 2) has the slope-intercept form is y = 1/4 x + 2 .

The probability that the first drawing gives green ball and second drawing a red ball is 2/7

Number of green balls = 4 green balls

Number of red balls = 4 red balls

Total number of balls in the bag = 4 + 4

= 8 balls

The probability = Number of favorable outcomes / Total number of outcomes

The probability of getting green balls in first draw = 4 / 8

= 1/2

First ball drawn was not replaced before drawing the second one

The probability of getting red ball in second draw = 4 / 7

The probability that the first drawing gives green ball and second drawing a red ball = (4/8) × (4/7)

Step-by-step explanation:

The equation for the relation is [tex]p=k \frac{qr^2}{s}[/tex].

The value of k when q = 5, r = 4 and s = 6 is 3.

The value of p when q = 8, r= 6 and s= 9 is 96.

The value of s when p= 10, q=5 and r = 2 is 6.

A connection between two different items is called variation. There are two categories of difference. Direct Variation is the name of the first one. When two variables move in the same direction, direct variation occurs. Additionally, as one variable rises, the other variable rises as well. Inverse Variation is the second kind. When the two variables move in the opposite direction, inverse variation occurs. Additionally, this occurs when one variable rises while the other falls.

Since p varies directly as q and the square of r and inversely as s. So the equation will be [tex]p=k \frac{qr^2}{s}[/tex].

Now, finding the value of k, for p = 40 when q = 5, r = 4 and s = 6,

[tex]p=k \frac{qr^2}{s}\\40=k \frac{5\times4^2}{6}\\k = 3[/tex]

Now, finding the value of p when q = 8, r= 6 and s= 9,

[tex]p=3 \frac{8\times 6^2}{9}\\=96[/tex]

Now, finding the value of s when p= 10, q=5 and r = 2,

[tex]10=3 \frac{5\times 2^2}{s}\\\\10=3\times \frac{20}{s}\\s=6[/tex]

Therefore, the equation for the relation is [tex]p=k \frac{qr^2}{s}[/tex] , the value of k when p = 40 when q = 5, r = 4 and s = 6 is 3, the value of p when q = 8, r= 6 and s= 9 is 96 and the value of s when p= 10, q=5 and r = 2 is 6.
