Answer:

The correct options are 1 and 3.

Step-by-step explanation:

From the given box plot it is clear that

[tex]\text{Minimum values}=34[/tex]

[tex]Q_1=42[/tex]

Q₁ is 25% of a data.

[tex]Median=46[/tex]

Median is 50% of a data.

[tex]Q_3=70[/tex]

Q₃ is 75% of a data.

[tex]\text{Maximum values}=76[/tex]

34 is minimum value of the data and 46 is median it means 50% of the data values lies between 34 and 46. Therefore option 1 is correct.

42 is first quartile and and 70 is third quartile. it means 50% of the data values lies between 42 and 70. Therefore option 2 is incorrect.

The difference between Minimum value and first quartile, Maximum value and third quartile is less than 1.5×(IQR), therefore it is unlikely to have any outliers in the data.

Hence option 3 is correct.

The interquartile range of the data is

[tex]IQR=Q_3-Q_1[/tex]

[tex]IQR=70-42=28[/tex]

The interquartile range is 28. Therefore option 4 is incorrect.

Range of the data is

[tex]Range=Maximum-Minimum[/tex]

[tex]Range=76-34=42[/tex]

The range is 42. Therefore option 5 is incorrect.

Answer:

Two distinct real solutions.

Step-by-step explanation:

Given the equation in the form [tex]ax^2+bx+c=0[/tex], you need to find the Discriminant with this formula:

[tex]D=b^2-4ac[/tex]

For the equation [tex]-2x^2+5x-3=0[/tex] you can identify that:

[tex]a=-2\\b=5\\c=-3[/tex]

Then, substituting these values into the formula, you get that the Discriminant is:

Simulation of randomly checking 25 vans, with over 100,000 miles=

                                                96408 03766 36932 41651 08410

Here  the digits 1, 2, and 3 represent a van with check engine light that turn on.

Approximately how many vans will have check engine lights come on?

From the above given data the digits 1, 2 and 3 that represented the particular model of van having check engine lights on are repeated 7 times in the simulation of randomly checking 25 vans, with over 100,000 miles

Hence 7 vans will have check engine lights come on!

In a simulation using the provided set of digits, we find that out of 25 vans, approximately 6 have check engine lights that turn on.

To solve this problem, we'd first identify all the digits that are either 1, 2, or 3 within the provided sequence of randomly generated digits. These digits, according to your problem, represent vans with check engine lights that turn on. The string you provided is 96408, 03766, 36932, 41651, and 08410.

Upon counting, the following digits in the string are 1, 2, or 3: '3', '2', '3', '1', '1', and '1'. This gives us a total of 6 occurrences.

Therefore, based on this simulation, if we were to randomly check 25 vans with over 100,000 miles, approximately 6 of them would have check engine lights that come on.

Answer:

The vertices feasible region are (0 , 15) , (10 , 15) , (20 , 5)

The minimum value of the objective function C is 125

Step-by-step explanation:

* Lets look to the graph to answer the question

- There are 3 inequalities

# y ≤ 15 represented by horizontal line (purple line) and cut the

  y-axis at point (0 , 15)

# x + y ≤ 25 represented by a line (green line) and intersected the

  x-axis at point (25 , 0) and the y- axis at point (0 , 25)

# x + 2y ≥ 30 represented by a line (blue line) and intersected the

  x-axis at point (30 , 0) and the y-axis at point (0 , 15)

- The three lines intersect each other in three points

# The blue and purple lines intersected in point (0 , 15)

# The green and the purple lines intersected in point (10 , 15)

# The green and the blue lines intersected in point (20 , 5)

- The three lines bounded the feasible region

∴ The vertices feasible region are (0 , 15) , (10 , 15) , (20 , 5)

- To find the minimum value of the objective function C = 4x + 9y,

  substitute the three vertices of the feasible region in C and chose

  the least answer

∵ C = 4x + 9y

- Use point (0 , 15)

∴ C = 4(0) + 9(15) = 0 + 135 = 135

- Use point (10 , 15)

∴ C = 4(10) + 9(15) = 40 + 135 = 175

- Use point (20 , 5)

∴ C = 4(40) + 9(5) = 80 + 45 = 125

- From all answers the least value is 125

∴ The minimum value of the objective function C is 125

The vertices of the feasible region are (0, 15), (10, 15), and (20, 5). The minimum value of the objective function C = 4x + 9y is 190 at the vertex (10, 15).

The feasible region is the area on a graph where all the constraints of a system of inequalities are satisfied. To find the vertices of the feasible region, we need to find the intersection points of the lines formed by the given constraints. By solving the system of equations, we find that the vertices of the feasible region are (0, 15), (10, 15), and (20, 5).

To find the minimum value of the objective function C = 4x + 9y, we substitute the x and y values of each vertex into the objective function and determine which vertex gives the smallest value. By evaluating the objective function at each vertex, we find that the minimum value is obtained at the vertex (10, 15) with a value of 4(10) + 9(15) = 190.

For this case we have that by definition, the density is given by:

ρ =[tex]\frac {M} {V}[/tex]

Where:

M: It's the mass

V: It's the volume

The volume of a solid cone is given by:

[tex]V = \frac {1} {3} \pi * r ^ 2 * h[/tex]

Where:

A: It's the radio

h: It's the height

Substituting the data we have:

 [tex]V = \frac {1} {3} \pi * (4) ^ 2 * 21\\V = \frac {1} {3} \pi * 16 * 21\\V = 401.92 \ cm ^ 3[/tex]

On the other hand, we have that by definition, the density of the platini is given by:

[tex]21.45 \frac {g} {cm ^ 3}[/tex]

Substituting in the initial formula, we look for the mass:

[tex]M = 401.92 \ cm ^ 3 * 21.45 \frac {g} {cm ^ 3}\\M = 8621.184 \ g[/tex]

ANswer:

The mass of the platinum cone is 8621.2 grams.

To find the mass of a solid platinum cone with a height of 21 cm and a diameter of 8 cm, calculate the volume using the formula for a cone (⅓πr²h) and then multiply by platinum's density (21,450 kg/m³) to get approximately 30.342 kg.

Calculate the Mass of a Platinum Cone

To determine the mass of a solid cone made of platinum with a given height and diameter, we must first calculate its volume and then use the density of platinum to find its mass. The density of platinum is approximately 21,450 kg/m³. The volume of a cone is given by the formula ⅓πr²h, where r is the radius and h is the height. For our cone with a height (h) of 21 cm and a diameter of 8 cm, the radius (r) would be half of the diameter, so r = 4 cm = 0.04 m. Plugging the values into the formula, we get:

Volume (V) = ⅓π(0.04 m)²×21 cm = ⅓π(0.0016 m²)× 0.21 m = 0.0014136 m³.

To find the mass (m), we multiply the volume by the density of platinum (ρ):

Mass (m) = Density (ρ) × Volume (V) = 21,450 kg/m³ × 0.0014136 m³ = 30.342 kg.

Therefore, the mass of the solid platinum cone is approximately 30.342 kilograms.

Answer:

The answer is 30

Step-by-step explanation:

Let [tex]x[/tex] be the amount of the 30% alloy and [tex]y[/tex] the amount of the 60% alloy the metalworker will use. However much is used, the final alloy will have a mass of

[tex]x+y=100[/tex]

kilograms. For each kg of the 30% alloy used, 0.3 kg is copper; similary, each kg of the 60% alloy contributes 0.6 kg, so that

[tex]0.3x+0.6y=0.54(x+y)=54[/tex]

Now,

[tex]x+y=100\implies y=100-x[/tex]

[tex]\implies0.3x+0.6(100-x)=54[/tex]

[tex]\implies60-0.3x=54[/tex]

[tex]\implies0.3x=6[/tex]

[tex]\implies x=20[/tex]

[tex]\implies y=100-20=80[/tex]

Answer:

interest earned= 12.47

the future value of an annuity= 162.47

Step-by-step explanation:

Given Data:

Interest rate,r= 4%

time,t = 2 years

monthly payment, P= 150

n= 12 as monthly

At the end of 2 years, final investment A= ?

As per the interest formula for compounded interest

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

Putting the values in above equation

= 150(1+0.04/12)^24

 = 162.47

Interest earned = A-P

                          = 162.47-150

                           = 12.47 !

The value of the integral ∫ ln(x)/x dx is  ln²(x)/2 + c

From the question, we have the following parameters that can be used in our computation:

S lnx/x dx

Express properly

So, we have

∫ ln(x)/x dx

The above expression can be integrated using substitution method

Let u = ln(x)

So, we have

du/dx = 1/x

Make dx the subject

du = dx/x

So, we have

∫ u du

Apply the power rule to integrate

∫ u du = u²/2

Substitute u = ln(x)

When integrated, we have

∫ ln(x)/x dx = ln²(x)/2 + c

Where c is a constant

Hence, the value of the integral is ln²(x)/2 + c
