Answer:

50x + 19.5 ≤ 130

Step-by-step explanation:

X is the number of days Mei Mei plans to rent the car

For driving 100 miles, Mei Mei will be charged $19.50. [130 times 0.15]

Mei Mei has a maximum budget of $130, so the inequality will have a less than or equal to sign

50x + 19.5 ≤ 130

After adding and subtracting the rational expressions , the simplified rational expression is 4x - 4/x² - 5/x³ + 9  .

We first simplify each expression inside the parentheses :

that means :

⇒ (2x + 5/x² -3x) = (2x - 3x + 5/x²) = (-x + 5/x²) ;

⇒ (3x + 5/x³ - 9x) = (-6x + 5/x³)  ;

⇒ (x + 1/x² - 9) = (-9 + x + 1/x²)  ;

Now we substitute these expressions into original equation/expression :

we get ; (-x + 5/x²) - (-6x + 5/x³) - (-9 + x + 1/x²)

Simplifying further ,

we get ;

⇒ -x + 5/x² + 6x - 5/x³ + 9 - x - 1/x²  ;

On Combining the like terms, we get ;

⇒ 4x - 4/x² - 5/x³ + 9

Therefore, the simplified rational expression is 4x - 4/x² - 5/x³ + 9.

Step-by-step explanation:

plug in values

Answer: 60 quarters and 40 dimes

Step-by-step explanation:

Step 1: Setup Coin Value and Coin Total Equation:

Coin Value Equation → 0.1d + 0.25q = $19.00 where d = dimes and q = quarters

Coin Total Equation → d + q = 100

Step 2: Rearrange Coin Total Equation in terms of dimes (d)

d = 100 - q  ← Revised Coin Total Equation

Step 3: Plug in our Revised Coin Total Equation for d into our Coin Value Equation:

0.1(100 - q) + 0.25q = $19.00

0.1(100) - 0.1(q) + 0.25q = $19.00

10 - 0.1q + 0.25q = $19.00

10 + (0.25 - 0.1)q = $19.00

10 + 0.15q = $19.00

Step 4: Subtract 10 from each side of the equation to isolate q

10 - 10 + 0.15q = $19.00 - 10

0.15q = 9

Step 5: Divide each side of the equation by 0.15 to isolate q

0.15q/0.15  =    9/0.15

q = 60

Step 6: Using our value for q, Solve for d using our Coin Total Equation:

d + 60 = 100

Subtracting 60 from both sides, we get d + 60 - 60 = 100 - 60

d = 40

Summarizing our word problem, we see that 60 quarters and 40 dimes add up to $19.00

The area of the region bounded by the parabola, the tangent line to this parabola at the point, and the axis is 20/3.

The area of the region bounded by the parabola y=x2, the tangent line to this parabola at (1,1) and the x-axis can be calculated by using integration.

First, we note that the equation of the tangent line to the parabola at (1,1) is y=2x-1. Then, the area of the region can be calculated by the equation:
A=∫01 (2x-1) - (x2)dx
A=∫01(x-x2)dx
A=∫01x dx - ∫01x2dx
A= (x2/2) |01 - (x3/3) |01
A=(1/2) - (1/3)
A=1/6
Let the given parabola be\(y^2=4ax\).

So, the equation of tangent at

\((a,a^2/4) is y=a^2/4 + (x-a)\).On solving this with the parabola equation we get,

x=3a/2, y=3a/2

So, the x intercept is 3a/2 and hence the required area is :∫\((3a/2)(a^2/4)\)dx + ∫\((a/2)(3a/2 - a^2/4)\) dx...on solving this, we get,\(20a^2/12 = 5a^2/3\)= 20/3.

Step-by-step explanation:

The circulation of F around the triangle is:

∫_C F · dr = ∫_T 3 dS = 3A = 21.

To apply Stokes' theorem, we need to find the curl of the vector field F:

curl(F) = ∇ x F = ( ∂Fz/∂y - ∂Fy/∂z ) i + ( ∂Fx/∂z - ∂Fz/∂x ) j + ( ∂Fy/∂x - ∂Fx/∂y ) k

        = (3) i + (0) j + (-2) k

        = 3i - 2k

Now we need to find the surface integral of the curl of F over the triangle T, which is the boundary of the path given in the question.

The normal vector to the triangle is pointing in the positive x direction, since the triangle is lying in the yz-plane and we are tracing it out in the positive x direction.

Therefore, the surface integral reduces to a line integral along the path:

∫_C F · dr = ∫_T (curl(F) · n) dS

            = ∫_T (3i - 2k) · (i) dS

            = ∫_T 3 dS

To find the surface area of the triangle T, we can use the formula:

A = 1/2 | AB x AC |

where AB and AC are the vectors from the initial point (5,0,0) to the other two vertices of the triangle. We have:

AB = (0,3,2) - (0,0,0) = (0,3,2)

AC = (5,0,2) - (0,0,0) = (5,0,2)

AB x AC = |-6i -10j + 15k| =  sqrt(196) = 14

So the surface area of T is A = 1/2 (14) = 7.

Therefore, the circulation of F around the triangle is:

∫_C F · dr = ∫_T 3 dS = 3A = 21.

The cost of gas was 3.051, the profit made by Mank is $366.96.

The amount of old copper tubing removed from air conditioning units is 68.8 kg.

The price paid per pound of copper tubing is $2.50.

The amount of gas used is 4 gallons.

The cost of 1 gallon of gas is $3.051.

By using dimensional analysis, we can convert 68.8 kilograms into pounds as shown below,

1 kg = 2.20462 lbs

68.8 kg = 68.8 × 2.20462 lbs= 151.663856 lbs

Using the above obtained value in pounds and the given price per pound, we can determine the total amount he was paid as shown below,

Total amount paid = 151.663856 × 2.5 = $379.16

The cost of 4 gallons of gas is 4 × 3.051 = $12.204

.Subtracting the gas cost from the amount paid, we get the profit,

Mank's profit = Total amount paid - Cost of gas= $379.16 - $12.204 = $366.956 or $366.96 (rounded to two decimal places)

Therefore, the profit made by Mank is $366.96.

The interval is from 0.9330 to 0.9350

For given condition;

mean = 0.9340

standard deviation = 0.0030

z-score at 98% = 2.33

n = size of sample = 47

Step 1: calculate the standard error of the mean

standard error of mean  =  z-score * standard deviation/sqrt(n)

                                        =  2.33 * 0.0030/\(\sqrt{47}\)

                                        = 0.0010

step 2: upper limit  =  mean + standard error

                                =  0.9340 + 0.0010

                                = 0.9350

           lower limit  =  mean - standard error

                              =  0.9340 - 0.0010

Measuring instruments may require calibration before use, an outside micrometer is not suitable for measuring part length and shaft diameter, and the vernier scale further divides smallest increment on main scale.

1.1.1. True. Some measuring instruments, such as gauges, require calibration before use to ensure their accuracy. This calibration often involves adjusting the zero mark on the gauge to align with a true zero reading, ensuring precise measurements.  1.1.2. False. An outside micrometer is not typically used for measuring part length and shaft diameter. It is more suitable for measuring external dimensions, such as the thickness or diameter of objects.

1.1.3. True. On a vernier scale, the smallest increment on the main scale is further divided by the vernier scale. This allows for more precise readings by measuring the difference between the two scales. 1.2. The micrometer has two scales, one on the sleeve and one on the thimble. The mark on the thimble is given in millimeters (mm). One revolution of the thimble equals the pitch of the screw thread, which is typically 0.5 mm or 0.025 inches, and corresponds to the linear movement of the spindle.

In summary, measuring instruments may require calibration before use, an outside micrometer is not suitable for measuring part length and shaft diameter, and the vernier scale further divides the smallest increment on the main scale.

Step-by-step explanation:

I have attached an image to make question clearer.

(A) Yes, the surface area of the block is twice the surface area of one of the triangular prisms. This is because the block has opposite faces to be equal since it's a cuboid, also all it's faces to be made of rectangles, therefore cutting it from the diagonal makes two equal triangles. Hence, the two triangular prisms are the same and since they are the same, two of the prisms will make up the block again. In conclusion, the surface area of the block will be times two of one of the triangular prism's surface area.

(B) since the surface area of the block is times two of the surface area of the triangular prism. Then we should look for the area of the prism.

Surface area of cuboid is given as:

2(L x W + L x H + W x H)

L = 4.5, W = 3 and H = 4.

Surface area = 2(4.5*3 + 4.5*4 + 3*4) = 87

Since the surface area is 87, then the surface area of one of the two triangles will be

87/2 = 43.5.

Item response theory is to latent trait theory as observer reliability is to inter-scorer reliability.

Reliability in a broad statistical sense is synonymous with consistency.

Item response theory (IRT) is a statistical framework used to model the relationship between the latent trait being measured and the observed responses to test items. It provides a way to estimate an individual's level on the latent trait based on their item responses.

The Observer reliability also known as inter-scorer reliability, is a measure of consistency or agreement among different observers or scorers when assessing or rating a particular phenomenon.

Both measures are concerned with the reliability or consistency of measurements but in different contexts and with different focal points.
