The equation of line in point-slope form passing through the points

(x₁ , y₁) and (x₂, y₂) with slope m is defined as;

y - y₁ = m (x - x₁)

Where, m = (y₂ - y₁) / (x₂ - x₁)

Given that the slope = 7 / 4

And, y - intercept = - 1

Now,

The equation of line with slope 7 / 4 and y - intercept - 1 is;

⇒ y = mx + b

⇒ y = 7 / 4 x + (-1)

⇒ y = 7/4 x - 1

So, We can graph the equation y = 7/4x - 1 as shown in figure.

The sum of the volume of the square prism and the square pyramid is 672 cubic inches.

What is prism ?

A prism is a three-dimensional geometric shape that has two identical, parallel polygonal bases and rectangular sides that connect the bases. The sides are perpendicular to the bases and their shape depends on the shape of the base. For example, if the base is a square, the prism is called a square prism. If the base is a rectangle, the prism is called a rectangular prism. The height of the prism is the perpendicular distance between the bases.

According to the question:
First, let's calculate the volume of the square prism:

The formula for the volume of a square prism is V = lwh, where l is the length, w is the width, and h is the height.

In this case, the length (l) and width (w) of the prism are both equal to a, which is 10 inches, and the height (h) is 6 inches. So, we have:

V_prism = lwh = 10 x 10 x 6 = 600 cubic inches

Next, let's calculate the volume of the square pyramid:

The formula for the volume of a square pyramid is V = (1/3)Bh, where B is the area of the base and h is the height.

In this case, the base of the pyramid is a square with side length b, which is 6 inches, so the area of the base is:

\(B = b^2 = 6^2 = 36 square inches\)

The height of the pyramid is also 6 inches, so we have:

V_pyramid = (1/3)Bh = (1/3) x 36 x 6 = 72 cubic inches

Finally, the total volume is the sum of the volumes of the prism and pyramid:

V_total = V_prism + V_pyramid = 600 + 72 = 672 cubic inches

Therefore, the sum of the volume of the square prism and the square pyramid is 672 cubic inches.

Answer:

75.2 kg

Step-by-step explanation:

His mass now is 80 kg which is 100% of his mass since 100% is the entire amount. He wishes to reduce his mass by 6%.

100% - 6% = 94%

After reducing his mass by 6%, his mass will become 94% of his original mass, 80 kg.

We need to find 94% of 80 kg.

94% of 80 kg = 94% × 80 kg = 0.94 × 80 kg = 75.2 kg

The surface area defined by the parametric equations x = u^2, y = uv, z = v^2/2 is 118.75 square units; where 0 ≤ u ≤ 5 and 0 ≤ v ≤ 3.

To is the area of ​​a place, we can use the model of that place for the parametric place. Formula:

A = ∫∫ (∂r/∂u) x (∂r/∂v)

dA

specifies the parametric equation where r(u, v) = (u^2, uv, v^2/2).

First we need to calculate the partial derivatives of (∂r/∂u) and (∂r/∂v):

∂r/∂u = (2u, v, 0)

∂r/∂v = (0 ) , u , v/2)

Next, we need to calculate the cross product of (∂r/∂u) x (∂r/∂v):

(∂r/∂u) x (∂r /∂v) = (v(v) /2, 2uv, -u^2)

Multiplying the size of the vector gives:

(∂r/∂u) x (∂r/∂v) = √( v^4/4 + 4u ^2v^2 + u ^4)

Now we integrate this magnitude at the given limit of u and v:

A = ∫[0.5]∫[0,3] √(v^4/4 + 4u^ 2v^2 + u^4) dv du

Calculating the two components together gives us the final answer:

The position value, r(t) is equals to the (t³/6)k + 2j and velocity value, v(t) is equals to ( t²/2 )k + 4i , for a(t) = tk, v(0) = 4i, r(0) = 2j.

Acceleration is defined as the rate of change of the velocity of an object with respect to time. Accelerations are vector quanty.

a = dv/dt

We have the following informations are available,

Initial velocity, v(0) = 4i

Initial position, r(0) = 2j

Acceleration at any time "t",

a(t) = tk

we have to determine the value of v(t) and r(t).

As we know, a(t) = dv(t)/dt = tk

integrating the above equation ,

v(t) = ∫tk dt = ( t²/2 )k + c

at t = 0 , v(0) = 0 + c = 4i ( since, v(0) = 4i

=> c = 4i

So, v(t) = ( t²/2 )k + 4i

Also, velocity is calculated by derivative of postion (r) with respect to time.

=> v(t) = dr(t) /dt

=> r(t) = ∫ v(t) dt

=> r(t) = ∫ ( t²/2 )k dt

integrating value of the right hand side,

r(t) = ( t³/2×3 )k +d

= (t³/6)k + d

At t = 0, r(0) = (0/6)k + d

=> r(0) = d = 2j

so, r(t) = (t³/6)k + 2j

Hence, the required position and velocity are

(t³/6)k + 2j and ( t²/2 )k + 4i.

The estimated probability that all four randomly selected young American men are 68 inches or shorter is approximately 0.004 or 0.4%.

To calculate the probability that all four randomly selected young American men are 68 inches or shorter, we need to consider the probability for each individual man and multiply them together.

Let's assume that the probability of an individual young American man being 68 inches or shorter is p. Since we are selecting four men at random, the probability of each man being 68 inches or shorter is the same, and we can multiply their probabilities together.

The probability of one man being 68 inches or shorter is p. Therefore, the probability of all four men being 68 inches or shorter is p × p × p × p = p^4.

However, we are not given the specific value of p in the problem statement. If we assume that the height of young American men follows a normal distribution, we can look up the corresponding z-score for a height of 68 inches or shorter and use the standard normal distribution to estimate the probability.

For example, if we find that a height of 68 inches corresponds to a z-score of -1.0, we can use a standard normal distribution table or a calculator to determine the probability of a z-score less than or equal to -1.0. Let's say this probability is approximately 0.1587.

Therefore, the estimated probability that all four randomly selected young American men are 68 inches or shorter would be (0.1587)^4 = 0.004.

Thus, the probability is approximately 0.004 or 0.4% rounded to three decimal places.

Answer:

5x + 4y = 80

Step-by-step explanation:
First, let us look at the given:

x = The number of songs purchased

y = The remaining balance of Renata's gift card

Coordinates:

1. (16,0)

2. (0,20)

Now let's look at the unknown:

Slope =?

Since we have the coordinates we can easily apply the slope formula

Now that we have our slope we can use either point-slope formation or slope-intercept formation, just pick whichever one you're comfortable with.

Point-slope formation

y - y1 = slope (x - x1)

Now just plug in the numbers:

y - 0 = 20/-16 (x - 16)

Now you multiply both sides by -16 to get rid of the fraction

-16(y - 0) = -16 (20/-16) (x - 16)

-16y - 0 = 20 (x - 16)

-16y = 20x - 320

Now subtract 20 from both sides.

-16y - 20x = 20x - 20x - 320

-20x - 16y = -320

Now we need to simplify both sides so we divide both sides by 4

-5x - 4y = -80

Now, remember, one of the rules of standard formation is that the coefficient of x cannot be smaller than zero. So you need to multiply both sides by -1.

-1 (-5x - 4y) = (-80) -1

5x + 4y = 80

The probability of getting strawberry is 11/60. The correct option is d.

To determine the probability of getting strawberry, we need to consider the probabilities of all the possible flavors and calculate the probability of strawberry using the information given.

Given probabilities:

Probability of getting cherry = 1/5

Probability of getting orange = 1/4

Probability of getting lemon = 1/3

Since there are only four flavors in total, we can calculate the probability of getting strawberry by subtracting the sum of the probabilities of cherry, orange, and lemon from 1.

Probability of getting strawberry = 1 - (1/5 + 1/4 + 1/3)

To simplify the calculation, we find a common denominator for 5, 4, and 3, which is 60.

Probability of getting strawberry = 1 - (12/60 + 15/60 + 20/60)

                                 = 1 - 47/60

                                 = 13/60

Therefore, the probability of getting strawberry is indeed 13/60, which corresponds to option d) 11/60 in the given list of options.

The moment of inertia of the thin rectangular sheet for an axis perpendicular to the plane and passing through one corner can be calculated using the parallel-axis theorem. The moment of inertia is given by I =\((1/3)M(a^2 + b^2).\)

In the first part, the moment of inertia of the sheet for the given axis is I = \((1/3)M(a^2 + b^2).\)

In the second part, the parallel-axis theorem states that the moment of inertia of a body about an axis parallel to and a distance 'd' away from an axis passing through the center of mass is equal to the moment of inertia about the center of mass plus the mass of the body multiplied by the square of the distance 'd'.

In this case, the axis passes through one corner of the sheet, which is a distance 'd' away from the center of mass. Since the sheet is thin, we can consider the mass to be uniformly distributed over the entire area. The center of mass is located at the intersection of the diagonals, which is (a/2, b/2).

The moment of inertia about the center of mass, I_cm, for a thin rectangular sheet is given by I_cm = (\(1/12)M(a^2 + b^2).\)

Applying the parallel-axis theorem, we have:

I =\(I_cm + Md^2.\)

Since the axis passes through one corner, the distance 'd' is equal to (a/2) or (b/2), depending on which corner is chosen. Therefore, the moment of inertia is given by:

I = \((1/12)M(a^2 + b^2) + M(a^2/4)\) or I =\((1/12)M(a^2 + b^2) + M(b^2/4).\)

Simplifying, we obtain:

We have-

Mean of population = 80

Standard deviation of population = 15

We are supposed to find the proportion of the population corresponding to scores between 65 and 110.

According to the formula of the Z-score.

z = (x-μ)/σ

X=interval, μ= population mean ,

σ= standard deviation

Here,x = 65,μ= 80,σ= 15 andz = (65-80)/15z = -1

Because the one-tailed test provides more power to detect an effect in one direction by not testing the effect in the other direction.

In statistics, power is defined as the likelihood of correctly rejecting a null hypothesis. In other words, avoiding a type II error. There are many ways to increase the power of a study to ensure that significant effects are not missed and incorrect conclusions are not drawn.

The main difference between one-tailed and two-tailed tests is that one-tailed tests will only have one critical region whereas two-tailed tests will have two critical regions.
