A team competes in 40 matches. Of those matches, he wins 16. What percent of the matches did the team win?

Answer:

The base charge = $18.5 and surcharge for each pound is = $1.75

Step-by-step explanation:

Solution:

- Denote:

     Base charge = $x   ...... For for Weight ≤ 1 lbs

     Additional charge = $y / unit pounds

- We are given that the customer is billed $29.00 for shipping a 7​-pound package. We can express this statement in terms of "x" and "y".

- The 1-pound out of 7 pounds will be charged with $x and remaining 6 additional pounds of weight will be charged "$y" for each unit of weight.

                         $x + ( 7 - 1 )*$y = $29.00    .... Eq1

- Similarly for a receipt of $64.00 for a 27​-pound package. The 1-pound out of 27 pounds will be charged with $x and remaining 26 additional pounds of weight will be charged "$y" for each unit of weight.      

                         $x + ( 27 - 1 )*$y = $64.00   .... Eq2

- Now solve the two equations simultaneously by subtracting Eq1 from Eq2:

                        (26 - 6 )*$y = $(64 - 29)

                        20*$y = $35

                         y = 1.75

                        $x = 29 - 6*1.75

                        x = 18.5    

- The base charge = $18.5 and surcharge for each pound is = $1.75

Step-by-step explanation:

Answer:

Step-by-step explanation:

Given that the regression equation for a set of paired data is = -23.8 + 2x. The values of x run from 100 to 400.

A new data point, P(194, 364.2), is added to the set.

From the given we can write it as y = -23.8+2x

Put x=194 in the above equation we get,

[tex]y(194) = -23.8+2\times 194[/tex]

[tex]=-23.8+ 388[/tex]

= 364.2

Hence, point P(194,364.2) is on regression line and it is not outlier.

Answer:

20.4°C

Step-by-step explanation:

Initial temperature 't1'= -4.8°C

Final temperature 't2'= 15.6°C

In order to find change in temperature, take the difference of above two temperatures. So,

Change in temperature 'ΔT' = t2 - t1

ΔT= 15.6 - (-4.8)

ΔT= 20.4 °C

Therefore, the change in temperature was 20.4°C

Answer:

  y = -3/4x +1

Step-by-step explanation:

Parallel lines have the same slope, so the slope of the line you want is -3/4. The point-slope form of the equation of a line is useful when you have this information:

  y -k = m(x -h) . . . . . . line with slope m through point (h, k)

  y -(-2) = -3/4(x -4)

If you want slope-intercept form, you can rearrange this ...

  y +2 = -3/4x +3

  y = -3/4x +1 . . . . . . subtract 2 from both sides

Answer:

There will be 50 bacteria remaining after 28 minutes.

Step-by-step explanation:

The exponential decay equation is

[tex]N=N_0e^{-rt}[/tex]

N= Number of bacteria after t minutes.

[tex]N_0[/tex] = Initial number of bacteria when t=0.

r= Rate of decay per minute

t= time is in minute.

The sample begins with 500 bacteria and after 11 minutes there are 200 bacteria.

N=200

[tex]N_0[/tex] = 500

t=11 minutes

r=?

[tex]N=N_0e^{-rt}[/tex]

[tex]\therefore 200=500e^{-11r}[/tex]

[tex]\Rightarrow e^{-11r}=\frac{200}{500}[/tex]

Taking ln both sides

[tex]\Rightarrow ln| e^{-11r}|=ln|\frac{2}{5}|[/tex]

[tex]\Rightarrow {-11r}=ln|\frac{2}{5}|[/tex]

[tex]\Rightarrow r}=\frac{ln|\frac{2}{5}|}{-11}[/tex]

To find the time when there will be 50 bacteria remaining, we plug N=50, [tex]N_0[/tex]= 500 and  [tex]r}=\frac{ln|\frac{2}{5}|}{-11}[/tex] in exponential decay equation.

[tex]50=500e^{-\frac{ln|\frac25|}{-11}.t}[/tex]

[tex]\Rightarrow \frac{50}{500}=e^{\frac{ln|\frac25|}{11}.t}[/tex]

Taking ln both sides

[tex]\Rightarrow ln|\frac{50}{500}|=ln|e^{\frac{ln|\frac25|}{11}.t}|[/tex]

[tex]\Rightarrow ln|\frac{1}{10}|={\frac{ln|\frac25|}{11}.t}[/tex]

[tex]\Rightarrow t= \frac{ln|\frac{1}{10}|}{\frac{ln|\frac25|}{11}.}[/tex]

[tex]\Rightarrow t= \frac{11\times ln|\frac{1}{10}|}{{ln|\frac25|}}[/tex]

[tex]\Rightarrow t\approx 28[/tex] minutes

There will be 50 bacteria remaining after 28 minutes.

Final answer:

To solve this problem, we use the formula for exponential decay and solve for the time when there are 50 bacteria remaining.

Explanation:

To solve this problem, we can use the formula for exponential decay: A = A0 * e^(kt), where A is the final population, A0 is the initial population, e is Euler's number (approximately 2.71828), k is the decay constant, and t is the time in minutes.

First, let's determine the value of k. We know that after 11 minutes, the population is 200 bacteria, so we can substitute these values into the formula to solve for k: 200 = 500 * e^(11k).

Divide both sides of the equation by 500: 0.4 = e^(11k).

Take the natural logarithm of both sides to solve for k: ln(0.4) = 11k.

Divide both sides by 11 to find the value of k: k ≈ -0.07761.

Now we can use the formula to solve for t when there are 50 bacteria remaining: 50 = 500 * e^(-0.07761t).

Divide both sides by 500: 0.1 = e^(-0.07761t).

Take the natural logarithm of both sides to solve for t: ln(0.1) = -0.07761t.

Divide both sides by -0.07761 to find the value of t: t ≈ 13.857 minutes.

Therefore, after approximately 14 minutes (rounded to the nearest whole number), there will be 50 bacteria remaining.

Answer:

68.2°

Step-by-step explanation:

AC is the longest side which means 90° is at B

SinA = BC/AC

sinA = 5/sqrt(29)

sinA = 0.9284766909

A = 68.19859051

A = 68.2°

To find the measure of angle A, we used the tangent function, which is the ratio of the side opposite the angle to the side adjacent to it. Using a calculator, the inverse tangent of the ratio BC/AB equals approximately 68.2 degrees.

In order to solve for angle A in a right triangle, we can use the concept of trigonometry. Specifically, we'll use the tangent (tan) function, which in a right triangle is the ratio of the side opposite the angle to the side adjacent to it. Since angle A is between sides AB and AC, the tangent of A would be defined as tan(A) = opposite side/adjacent side = BC/AB = 5/2.

After calculating the ratio, typically, we would use a calculator to find the arctan or inverse tangent of this ratio, which should give the angle A in degrees. In this case, the arctan(5/2) equals about 68.2 degrees when rounded to the nearest tenth.

To calculate the mean number of push-ups Justin did each weekday, add up the total push-ups for the week and divide by 5. Justin did a mean of 186.8 push-ups per day.

Explanation:

To find the mean number of push-ups Justin did each weekday, we need to add the number of push-ups he did each day and then divide by the number of days. The steps are:

Therefore, the mean number of push-ups Justin did on a weekday is 186.8 push-ups.

Final answer:

The mean number of push-ups Justin did each weekday is calculated by adding the total push-ups for all the days and dividing by the number of days, resulting in 186.8 push-ups.

Explanation:

To find the mean number of push-ups, Justin did over the weekdays, you need to sum up the total push-ups and then divide by the number of days.

Add the number of push-ups for each day: 888 (Monday) + 14 (Tuesday) + 18 (Wednesday) + 6 (Thursday) + 8 (Friday) = 934 push-ups in total.

Divide the total number of push-ups by the number of days: 934 ÷ 5 days = 186.8 push-ups.

Therefore, the mean number of push-ups Justin did each weekday is 186.8 push-ups.

Use 3 as the y-intercept. Factor the equation to find the solutions

(x - 1) (x - 3) so 1 and 3 are the x-intercepts. The vertex of the graph is at (2,-1).

I also graphed the equation below.

If this answer is correct, please make me Brainliest!

The graph of [tex]y = x^2 - 4x + 3[/tex] is a parabola that opens upward with its vertex at (2, -1). It intersects the x-axis at x = 3 and x = 1 and the y-axis at y = 3.

The equation is [tex]y = x^2 - 4x + 3.[/tex]

Use the formula x = -b / (2a) to find the x-coordinate of the vertex. In this case, a = 1, b = -4.

x = -(-4) / (2*1)

= 4 / 2

= 2.

So, the x-coordinate of the vertex is 2.

Subtitute x = 2 into the equation:

[tex]y = (2)^2 - 4(2) + 3[/tex]

= 4 - 8 + 3

= -1.

The y-coordinate of the vertex is -1.

The vertex is at (2, -1).

The y-intercept, we will set x = 0 in the equation:

[tex]y = (0)^2 - 4(0) + 3[/tex]

= 0 - 0 + 3

= 3.

The get x-intercepts, we set y = 0 in the equation:

[tex]0 = x^2 - 4x + 3.[/tex]

(x - 3)(x - 1) = 0.

x = 3 or x = 1.

The x-intercepts are 3 and 1.

Now, we will plot the y-intercept and x-intercepts. The y-intercept is at (0, 3), and the x-intercepts are at (3, 0) and (1, 0).

Answer:

50(115-y) + 25y = 4125             [from eq2]

    5750 - 50y  + 25y = 4125           [distribute]

    5750 - 25y = 4125

     -25y = -1625

        y = 65             [divide both sides by (-25)]

There are 65 small boxes.

Put that value into either equation (now, which is easier?) to solve for x:

The required number of boxes that the truck contain is 55 small boxes and 65 large boxes.  

Given that, the large boxes weigh 45 pounds each, and the small boxes weigh 25 pounds each. There are 120 boxes in all, the truck is carrying a total of 4300 pounds.

The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.

here,
Let the number of large boxes will be l and the number of small boxed be s,

According to the question,
l + s = 120
l = 120 - s - - - - - (2)
Again,
45l + 25s = 4300
put l in the above equation,
45[120 - s] + 25s = 4300
5400 - 45s + 25s = 4300
20s = 1100
s = 1100/20
s = 55
Now,
l = 120 - 55
l = 65

Thus, the required number of boxes that the truck contain is 55 small boxes and 65 large boxes.

The objective function in this scenario is minimizing the cost of shipping goods from the plant to the store.

The goal of the Linear Programming Problems (LPP) is to determine the best value for a given linear function. The ideal value may be either the highest or lowest value. The specified linear function is regarded as an objective function in this situation.

The most likely goal function, if we were to create a linear programme for this situation, would be to reduce the cost of shipping from the plants to the stores. This is important since it can become an expensive bottleneck.

Despite the fact that there are three factories and three stores, the costs will not be minimized if the same amount of goods are produced in each plant and carried to a specific store. In fact, the likelihood that each facility generates a distinct volume of items further exacerbates the issue.

Finding the optimal distribution of shipping commodities from each facility to each retailer is important as a result.

Answer: y=  −3 /10 x +  2 /5

Step-by-step explanation:

Let's solve for y.

−3(x+y)+4=7y

Step 1: Add -7y to both sides.

−3x−3y+4+−7y=7y+−7y

−3x−10y+4=0

Step 2: Add 3x to both sides.

−3x−10y+4+3x=0+3x

−10y+4=3x

Step 3: Add -4 to both sides.

−10y+4+−4=3x+−4

−10y=3x−4

Step 4: Divide both sides by -10.

−10y /−10  =  3x−4 / −10

y=  −3 /10 x+  2 /5

Answer:

x=40

Step-by-step explanation:

Since a circle has a total of a 360 degree angle the equation is

(x+40)+(2x+60)+(3x+20)=360

to simplify this we can bring all the variables(x) together and the numbers together.

(x+2x+3x)+(40+60+20)=360

6x+120=360

6x=360-120

6x=240

6x/6=240/6

x=40

The sum of all the degrees in a circle is 360 degrees. Knowing this you can make a equation:

(x + 40) + (2x + 60) + (3x + 20) = 360

x + 40 + 2x + 60 + 3x + 20 = 360

(x + 2x + 3x) + (40 + 60 + 20) = 360

Now you must combine like terms  This means the numbers with the same variables must be combined...

(x + 2x + 3x) + (40 + 60 + 20) = 360

x + 2x + 3x = 6x

(6x) + (40 + 60 + 20) = 360

Now combine the terms without variables (on the left side of the equation) together

(6x) + (40 + 60 + 20) = 360

40 + 60 + 20 = 120

(6x) + 120 = 360

Now we must isolate x. To do this first bring 120 to the right side by subtracting 120 to both sides (what you do on one side you must do to the other). Since 120 is being added on the left side, subtraction (the opposite of addition) will cancel it out (make it zero) from the left side and bring it over to the right side.

6x + 120 - 120 = 360 - 120

6x + 0 = 240

6x = 240

To further isolate x  you must divide 6 to both sides. Since x is being multiplied by 6 you must divide 6 to both sides to make 6 one on the left side and bring it over to the right side

6x / 6 = 240 / 6

1x = 40

x = 40

Check:

(40 + 40) + (2(40) + 60) + (3(40) + 20)

(80) + (80 + 60) + (120 + 20)

80 + 140 + 140

Given that:

R(x) = [tex]\frac{17}{2x+1}[/tex] + 34x − 17

As we know that derivative of revenue function is marginal revenue function .

We will use following rules of derivative

=> dR/ dx = [tex]\frac{-17*2}{(2x+1)^{2} } + 34[/tex]

=> R' (x) =   [tex]\frac{-34}{(2x+1)^{2} } + 34[/tex]

=> R '(2000) =  [tex]\frac{-34}{(2*2000+1)^{2} } + 34[/tex] = 34

The revenue when 2000 units are sold is:

R(2000) = [tex]\frac{17}{2*2000+1}[/tex] + 34*2000 − 17 = $69,783

The marginal revenue be "34" and revenue change be "$69,783".

The increase throughout income caused by the acquisition of one more unit of production, is a Marginal revenue. Although marginal income can stay unchanged at a predetermined interval, it's indeed subject to the regulations of decreasing returns as well as will ultimately slow as outcome level grows.

According to the question,

Revenue function,

R(x) = [tex]\frac{17}{2x+1}[/tex] + 34x - 17

Units sold = 2000

(a) The marginal revenue be:

→ [tex]\frac{dR}{dx}[/tex] = [tex]-\frac{17\times 2}{(2x+1)^2}[/tex] + 34

R'(x) = [tex]- \frac{34}{(2x+1)^2}[/tex] + 34

By substituting "x = 2000",

R'(2000) = [tex]- \frac{34}{(2\times 2000+1)^2}[/tex] + 34

              = 34

(b) The revenue change be:

→ R(2000) = [tex]\frac{17}{2\times 2000+1}[/tex] + 34 × 2000 - 17

                 = 69,783 ($)

[tex]4 = (2 + Q + 9 + 4 + 1 + 0 + 0 + 7 + 7 + 3) mod 9\\4 = (Q + 33) mod 9\\4 = Q mod 9 + 33 mod 9\\4 = Q mod 9 + 6\\Q mod 9 = 4 - 6\\Q mod 9 = -2\\Q = -2 mod 9\\Q = 7[/tex]

Therefore, Q is 7 because we have to cancel out the negative sign by adding the modulo base (9) to the negative number: -2 + 9 = 7.

d) 66687Q03201

[tex]1 = (6 + 6 + 6 + 8 + 7 + Q + 0 + 3 + 2 + 0) mod 9\\1 = (Q + 38) mod 9\\1 = Q mod 9 + 38 mod 9\\1 = Q mod 9 + 2\\Q mod 9 = 1 - 2\\Q mod 9 = -1\\Q = -1 mod 9\\Q = 8[/tex]

Therefore, Q is 8 because we have to cancel out the negative sign by adding the modulo base (9) to the negative number: -1 + 9 = 8.

For the given postal money order scenarios, the smudged digit, Q, is determined as follows: Scenario a - either 0 or 9, Scenario b - 5, Scenario c - 5, and Scenario d - 3.

Let's analyze the given postal money order scenarios and determine the smudged digit, Q, using the provided algorithm:

Scenario a:

ID number: 493212Q0688

Sum of the first 10 digits: 4 + 9 + 3 + 2 + 1 + 2 + 0 + 6 + 8 + 8 = 43

43 divided by 9 equals 4 with a remainder of 7.

Therefore, the smudged digit, Q, is either 0 or 9.

Scenario b:

ID number: 850Q9103858

Sum of the first 10 digits: 8 + 5 + 0 + 9 + 1 + 0 + 3 + 8 + 5 + 8 = 47

47 divided by 9 equals 5 with a remainder of 2.

Therefore, the smudged digit, Q, is 5.

Scenario c:

ID number: 2Q941007734

Sum of the first 10 digits: 2 + 7 + 9 + 4 + 1 + 0 + 0 + 7 + 7 + 3 = 40

40 divided by 9 equals 4 with a remainder of 4.

To cancel out the negative sign in the remainder, we add the modulo base (9) to the negative number: -4 + 9 = 5.

Therefore, the smudged digit, Q, is 5.

Scenario d:

ID number: 66687Q03201

Sum of the first 10 digits: 6 + 6 + 6 + 8 + 7 + 0 + 3 + 2 + 0 + 1 = 33

33 divided by 9 equals 3 with a remainder of 6.

To cancel out the negative sign in the remainder, we add the modulo base (9) to the negative number: -6 + 9 = 3.

Therefore, the smudged digit, Q, is 3.
