5x-2y=30

Given x=8

5×8-2y=30

-2y=30-40

y=5

Answer:

Step-by-step explanation:

y varies directly with x then, y=kx

for x = 2 and y= -10 we get:

-10 = 2k

k= -5

when x = 12

y = -5 * (12) = -60

The manufacturer would lose a total profit of $100,000 and a per-unit profit of $10 by producing 70,000 units instead of the demanded 80,000 units.

To calculate the total profit and per-unit profit lost, we need to consider the difference between the actual production and the demand, as well as the profit per unit.

Let's assume the profit per unit is $10.

The manufacturer produces 70,000 units, but the demand is for 80,000 units, resulting in a shortage of 10,000 units.

Total profit lost = shortage * profit per unit = 10,000 * $10 = $100,000

Therefore, the total profit lost in this scenario is $100,000.

To calculate the per-unit profit lost, we divide the total profit lost by the shortage:
Per-unit profit lost = total profit lost / shortage = $100,000 / 10,000 = $10

Therefore, the per-unit profit lost in this scenario is $10.

By understanding the difference between the actual production and the demand, as well as the profit per unit, we can determine the total profit and per-unit profit lost when producing fewer units than the demand.

The area of the parallelogram is √19 square units.

To calculate the area of a parallelogram using the cross product of two vectors, we can follow these steps for the given vertices P(2, 2, 1), Q(5, 3, 3), R(9, 8, 10), and S(6, 7, 8):

Step 1: Find two vectors

We find two vectors by subtracting the coordinates of two opposite vertices. Let PQ be a diagonal of the parallelogram. Then, we have PQ = Q - P = (5, 3, 3) - (2, 2, 1) = (3, 1, 2). Similarly, we can find SR by subtracting the coordinates of the other two opposite vertices. SR = R - S = (9, 8, 10) - (6, 7, 8) = (3, 1, 2).

Step 2: Take the cross product of the vectors

The cross product of two vectors gives us a vector that is perpendicular to both vectors. The magnitude of this vector is equal to the area of the parallelogram. To find the cross product, we take the determinant of the matrix shown below:

| i     j      k |

| 3     1     2 |

| 3     1     2 |

where i, j, and k are the unit vectors in the x, y, and z directions, respectively. Expanding the determinant, we get:

(3 x 1 - 1 x 2) i - (3 x 2 - 1 x 3) j + (3 x 1 - 3 x 2) k

= (3 - 2) i - (6 - 3) j + (3 - 6) k

= i - 3 j - 3 k

Step 3: Find the area

The area of the parallelogram is equal to the magnitude of the cross product of the vectors PQ and SR. Therefore, the area of the parallelogram is √(1² + (-3)² + (-3)²) = √19 square units.

The value of "x" in the given figure and question is 20 units.

As per the question statement, We are given a figure in which we are supposed to find the value of x.

Before solving the question, if we observe the figure, we can conclude that this question will include the concepts of right angled triangle or specifically Pythagoras Theorem, which states that

\(Perpendicular^{2} + base^{2} = hypotenuse^{2}\) where perpendicular, base and hypotenuse are the three sides of the right angled triangle.

In Triangle RTQ

using Pythagoras Theorem

\(RQ^{2} = TQ^{2} +TR^{2} \\RQ=x\\x^{2} = 16^{2} + TR^{2} \\TR^{2} = x^{2} -16^{2}\)

Now considering triangle SRT

using Pythagoras Theorem

\(SR^{2} = RT^{2} + ST^{2} \\SR^{2} = (x^{2} -16^{2}) +9^{2}\\\)

Now considering triangle RSQ

using Pythagoras Theorem

\(SQ^{2} = SR^{2} +RQ^{2} \\(9+16)^{2} = SR^{2} + RQ^{2} \\(9+16)^{2} = x^{2} -7^{2}+x^{2} \\ (9+16)^{2} =2x^{2} -7^{2} \\25^{2}+7^{2} = 2x^{2}\)

\(2x^{2} =674\)

\(x^{2} =337\\x=\sqrt{337} \\x=18.357\)

Therefore x = 18.357 approx 20 units.

Answer:

q = 3.5

Step-by-step explanation:

-15 = 5(3q - 10) - 5q

-15 = (5*3q + 5*-10) - 5q

-15 = 15q - 50 - 5q

-15 + 50 = 15q - 5q

35 = 10q

q = 35/10

q = 3.5

Check:

-15 = 5(3*3.5 - 10) - 5*3.5

-15 = 5(10.5 - 10) - 17.5

-15 = 5*0.5 - 17.5

-15 = 2.5 - 17.5

49th term = 225

Step-by-step explanation:

The following sequence: -15, -10, -5, 0, -5... is an example of an arithmetic progression.

An arithmetic progression or AP for short, is a sequence in which the difference between successive terms is constant. This difference is known as the common difference, and can be found by subtracting a term by its preceding term.

The general formula, for the nth term of an arithmetic progression, is thus:

Tn = a + (n - 1)d, where a = first term, and d = common difference.

In the sequence: -15, -10, -5, 0, 5...,

a = -15, and d = -10--15 = 5

T49 = -15 + (49 - 1)5 = 225

The weight distribution of newborn African lions may not necessarily follow a normal distribution, and the actual percentages can vary based on the specific data available.

To determine the percentage of newborn African lions that weigh less than 3 pounds and the percentage that weigh more than 3.8 pounds, we would need statistical data on the weight distribution of newborn African lions. Since we don't have that information, we cannot provide the exact percentages.

However, if we assume that the weights of newborn African lions follow a normal distribution, we can use the properties of the standard normal distribution to make an estimation.

For the percentage of newborn African lions weighing less than 3 pounds:

We would need to know the mean and standard deviation of the weight distribution to calculate the Z-score for a weight of 3 pounds and then find the corresponding percentage using a standard normal distribution table. Without this information, we cannot provide an accurate estimation.

For the percentage of newborn African lions weighing more than 3.8 pounds:

Similarly, we would need the mean and standard deviation of the weight distribution to calculate the Z-score for a weight of 3.8 pounds and find the corresponding percentage using a standard normal distribution table. Without the required information, we cannot provide a specific estimation.

the probability P[X ≤ Y] is equal to 1.

To find the probability P[X ≤ Y], we need to integrate the joint probability density function (PDF) over the region where X is less than or equal to Y.

Given the joint PDF:

f(x, y) = cxy, 0 ≤ x ≤ y ≤ 1,

f(x, y) = 0 elsewhere.

To find the constant c, we can integrate the joint PDF over its entire support and set it equal to 1 (since the total probability of the sample space is 1):

1 = ∫∫f(x, y) dx dy

Integrating over the region 0 ≤ x ≤ y ≤ 1:

1 = ∫∫cxy dx dy

   = c∫[0,1]∫[x,1]xy dy dx

Integrating with respect to y first:

1 = c∫[0,1] [xy²/2] [x,1] dx

   = c∫[0,1] (x/2 - x³/2) dx

   = c[(x²/4 - x⁴/8)] [0,1]

   = c(1/4 - 1/8)

   = c/8.

Since c = 8, we can now determine the probability P[X ≤ Y]:

P[X ≤ Y] = ∫∫f(x, y) dx dy

           = ∫∫8xy dx dy

           = 8∫[0,1]∫[x,1]xy dy dx.

Integrating with respect to y first:

P[X ≤ Y] = 8∫[0,1] [xy²/2] [x,1] dx

           = 8∫[0,1] (x/2 - x³/2) dx

           = 8[(x²/4 - x⁴/8)] [0,1]

           = 8(1/4 - 1/8)

           = 8/8

           = 1.

Therefore, the probability P[X ≤ Y] is equal to 1.

Answer:

m = 600 feet/minute

Step-by-step explanation:

In this scenario, the elevation of the hot air balloon can be represented as a linear function of time. Let's use t to denote time in minutes and h(t) to denote the elevation of the balloon in feet at time t.

We know that the balloon starts at an elevation of 300 feet, so we can write the equation of the line as:

h(t) = 600t + 300

The slope of the line represents the rate of change of the elevation with respect to time, which is the same as the rate at which the balloon is ascending. Therefore, the slope of the line is equal to the ascent rate of the balloon, which is 600 feet per minute.

So the slope of the line is:

m = 600 feet/minute

 Total volume of the salt shaker is 56.52+706.5=763.02 cm³
