On subtracting 20 from twice a number we get 50, then the number is 35 in this context.

This is referred to as a type of mathematical operation in which one number is taken or deducted from the other and the sign is ( - ). this expression is used in every facet of life for their daily activities.

We were told that 20 was subtracted from twice a number to give 50 which means that twice the number is 70. The exact number will therefore be 70/2 which will then result in 35 and is therefore the most appropriate choice.

Step-by-step explanation:

The equation of line is y = 12x and the number of boxes the shipping company can pack in 18 hour period is 216 boxes

The equation of a line is expressed as y = mx + b where m is the slope and b is the y-intercept

And y - y₁ = m ( x - x₁ )

y = y-coordinate of second point

y₁ = y-coordinate of point one

m = slope

x = x-coordinate of second point

x₁ = x-coordinate of point one

The slope m = ( y₂ - y₁ ) / ( x₂ - x₁ )

Given data ,

Let the number of hours be x

Let the number of boxes be y

Let the equation of line be represented as A

Now , the value of A is

Let the first point be P ( 5 , 60 )

Now , the slope of the line m = y/x

Substituting the values in the equation , we get

Slope m = 60 / 5 = 12

Now , the equation of line is y - y₁ = m ( x - x₁ )

Substituting the values in the equation , we get

y - 60 = 12 ( x - 5 )

y - 60 = 12x - 60

y = 12x

Now , when x = 18 hours

y = 12 ( 18 ) boxes

y = 216 boxes

Hence , the number of boxes is 216 boxes

Step-by-step explanation:

The relative minimum of the function include the following: -2.

In this exercise, you are required to determine the relative minimum of the function with respect to the vertex form of a quadratic function h(x) that is written in standard form. Mathematically, the vertex form of a quadratic equation is given by this formula:

y = a(x - h)² + k

Where:

Based on the information provided about this quadratic function, we can reasonably infer and logically deduce that that its vertex is at x equals negative three and y equals negative two.;

Vertex (h, k) = (-3, -2)

Therefore, the relative minimum is equal to -2.

Answer:

(3,1)

Step-by-step explanation:

When a point is reflected across the y axis, the sign of its x coordinate flips. Since point A is at (-3,-5), when it is reflected across the y axis its new position will be (3,-5). Now, point A is 3 units from the line y=-2, meaning that when it is reflected across it will be 3 units away from the other direction. (-2+(3))=1, meaning that the final coordinates of point A are (3,1). Hope this helps!

Answer:

\(\$600\)

Step-by-step explanation:

Total amount raised for relay for life = $3000

Although goal is to raise \(\frac{1}{3}\) of the total amount by the end of the month. But unfortunately, Taylor was only able to raise 1/5 of his goal for the month.

Therefore,

Ratio of amount raised for the month \(=\frac{1}{5}\) of the goal.

So,

amount raised for the month \(=\frac{1}{5} (3000)=\$600\)

If daily demand is constant at 10 units per day, and lead time averages 12 days with a standard deviation of 3 days, 95 percent service requires 49 units safety stock .Option (C) is correct.

To calculate safety stock, we need to consider the deviation in lead time and the desired service level. The formula for safety stock is:
Safety Stock = (Z-score for desired service level * Standard deviation of lead time * Average daily demand)
Assuming a normal distribution, the Z-score for 95% service level is 1.645. Substituting the given values, we get:
Safety Stock = (1.645 * 3 * 10)

=49.35 units
Rounding up to the nearest whole number, the answer is option C) 49 units.
It is important to note that safety stock is not the same as average inventory level. Safety stock is a buffer that protects against variability in demand and lead time, and it helps ensure that we can meet customer demand without stockouts. Averages, on the other hand, represent typical values over time.

For a rectangular granite slab purchased by Bob with area 18 sq. feet who replacing the laminate countertop, the width of slab is three feet.

We have a homeowner is replacing the laminate countertop with granite. For this he purchased a slab of granite that is 18 square feet. That is area of slab = 18 sq. feet

Length of slab, l = 6 feet

We have to determine the wide of slab. The shape of slab is rectangular. So, we have calculate the width of rectangular slab. Let the width be equal to ' x feet' . As we know, area of rectangle is written as product of length and width of rectangle. Thus, Area = l × x

=> 18 feet² = 6 feet × x

dividing both sides by 6

=> x = 3 feet

Hence, required width is 3 feet.

The overall shape of the distribution of soldiers' foot lengths was likely symmetric or approximately bell-shaped.

The distribution of soldiers' foot lengths can be described as symmetric or bell-shaped. The majority of foot lengths cluster around the center, with fewer foot lengths deviating significantly. The center of the distribution, representing the average foot length, can be determined using the mean.

Analyzing the shape through a histogram or box plot helps identify symmetry. A symmetric shape with a peak in the middle and evenly tapering tails indicates a bell-shaped distribution.

Understanding the distribution's shape and center allows us to infer the overall characteristics of the soldiers' foot lengths.

Rewrite in vertex form and use this form to find the vertex (h, k).

Answer:

\(\sf Vertex \left(\dfrac{3}{2}, \dfrac{-81}{4}\right)\)

Step-by-step explanation:

          y = x² - 3x - 18

       Add 18 to both sides.

           y + 18 = x² - 3x

     Divide the co-efficient of x by 2 and square the result and then add it to both sides.

      Co-efficient of x = 3. Divide 3 by 2and add (3/2)² to both sides

          \(\sf y + 18 + \left(\dfrac{3}{2}\right)^2= x^2 - 3x + \left(\dfrac{3}{2}\right)^2\\\\\\y + 18+\dfrac{9}{4}=x^2 - 3x + \dfrac{9}{4}\\\\\\\)

          \(\sf y + \dfrac{18*4}{1*4}+\dfrac{9}{4}=\left(x - \dfrac{3}{2}\right)^2\\\\\\y + \dfrac{72}{4}+\dfrac{9}{4}=\left(x - \dfrac{3}{2}\right)^2\\\\\\y + \dfrac{81}{4}=\left(x-\dfrac{3}{2}\right)^2\\\\ y = \left(x-\dfrac{3}{2}\right)^2 -\dfrac{81}{4}\\\\\)
