Step-by-step explanation:

The hospital uses the quadratic model to predict the number of births

The equation of the quadratic model is f(x) = 4 x^2 -43 x +178, and the number of births for month 8 is 90

To determine the quadratic model, the make use of a graphing calculator, that has the following calculation summary

A quadratic model is represented as:

[tex]y= ax^2 + bx + c[/tex]

So, we have:

[tex]y = 4.339 x^2 -43.461 x +178.3[/tex]

Approximate

[tex]y = 4 x^2 -43 x +178[/tex]

Rewrite as:

[tex]f(x) = 4 x^2 -43 x +178[/tex]

At the 8th month, we have x = 8.

So, the function becomes

[tex]f(8) = 4 * 8^2 -43 *8 +178[/tex]

[tex]f(8) = 90[/tex]

Hence, the number of births for month 8 is 90

The surface area of the triangular prism is 533.6 cm².

where

b and h are the base and height of the triangular base. Therefore,

Therefore,

x = 12 cm

y = 10 cm

z = 15.6 cm

l = 11 cm

Therefore,

SA = 12 × 10 + (12 + 10 + 15.6)11

SA = 120 + (22 + 15.6)11

SA = 120 + (37.6)11

SA = 120 + 413.6

It will take him 5 hrs to write a 20-page essay because he can write 4 pages in 1 hour.

Hope this helps!

Answer:

5 hours

Step-by-step explanation:

For 12 pages, he spent 3 hours. So it takes him 1 hour to write 4 pages. (12 ÷ 3 = 4) If for each 4 pages 1 hour is spent respectively, then for 20 pages: 20 ÷ 4 = 5 hours will be spent.

keeping in mind that perpendicular lines have negative reciprocal slopes, let's check for the slope of the equation above

[tex]12x-9y = 27\implies -9y=-12x+27\implies y=\cfrac{-12x+27}{-9} \\\\\\ y=\cfrac{-12x}{-9}+\cfrac{27}{-9}\implies y=\stackrel{\stackrel{m}{\downarrow }}{\cfrac{4}{3}}x-3\impliedby \begin{array}{|c|ll} \cline{1-1} slope-intercept~form\\ \cline{1-1} \\ y=\underset{y-intercept}{\stackrel{slope\qquad }{\stackrel{\downarrow }{m}x+\underset{\uparrow }{b}}} \\\\ \cline{1-1} \end{array}[/tex]

therefore

Answer:

210 is the rate per hour and 1,050 people in 5 hours

Step-by-step explanation:

Answer:

Step-by-step explanation:

    You need to get answer to people per hour first. 70 people could ride the ferris wheel in 20 minutes. 20 minutes is 1/3 of 60 minutes, which is an hour. So you multiply both the time and the amount of people by 3. 70 times 3 is 210. This is the amount of people that could ride the ferris wheel in 1 hour. Then, we need to multiply this number by 5, because we need the amount of people that could ride the ferris wheel in 5 hours, not 1 hour. So 210 times 5 is 1,050. 1,050 people could ride the ferris wheel in 5 hours.

    Next, we need to find the rate per hour. You already have the answer to that though. It is the amount of people that could ride the ferris wheel, so your  previous number: 210. Your rate would be 210 people per hour could ride the ferris wheel.

Answer: C

Step-by-step explanation:

P - Value

Is the evidence against the null hypothesis.

The lower the p-value, the greater the chance of rejection of the null hypothesis.

The greater the p-value, the greater the chance to accept the null hypothesis.

So, in other words, the question asks the probability of having accepted a null hypothesis.

So using the above statement we can say that statement C is true.

Answer:

342 pairs

Step-by-step explanation:

Given that,

New pair of sneakers produced by the Nike factory = 5,814

The company wants to distribute the sneakers evenly among their 17 warehouses.

We need to find the no of pairs of the Air Jordan sneakers will each warehouse receives. It can be calculated as follows :

[tex]n=\dfrac{\text{total pair of sneakers}}{\text{no of warehouses}}\\\\n=\dfrac{5814}{17}\\\\n=342[/tex]

It would mean that each warehouse will receive 342 pair of sneakers.

Answer:

The value  is  [tex] k =109.6 \ miles [/tex]

Step-by-step explanation:

The diagram illustrating the question is shown on the first uploaded image

From the question we are told that

   The distance from city A to B is   AB =  467.3 miles

   The bearing from B to  C is  [tex]\theta_{BC} =  N 28.7E[/tex]

   The bearing from B to  A is  [tex]\theta_{BA} =  N 60.7E[/tex]

   The  bearing from A to  B is   [tex]\theta_{AB} =  S60.7W[/tex]

    The  bearing from A to  C is   [tex]\theta_{AC} =  S79.1W[/tex]

Generally from the diagram

     [tex]\theta_A  =  180 - 60.7 -79.1[/tex]

=>  [tex]\theta_A  =  40.2 ^o[/tex]

Also

     [tex]\theta_B  =  32^o [/tex]

and  

      [tex]\theta_C  =  180 - (\theta_A  +\theta_B )[/tex]

=>   [tex]\theta_C  =  180 - (40.2  + 32 )[/tex]

=>   [tex]\theta_C  =  107.8 ^o[/tex]

Generally according to Sine Rule

     [tex]\frac{BC}{sin (\theta_A)}  = \frac{CA}{sin (\theta_B)} =\frac{AB}{sin (\theta_C)}[/tex]

=>   [tex]\frac{BC}{sin (40.2)}  = \frac{CA}{sin (32)} =\frac{467.3 }{sin (107.8)}[/tex]    

So

     [tex]\frac{BC}{sin (40.2)}  = \frac{467.3 }{sin (107.8)}[/tex]

=>  [tex]BC = 316.8 \ miles[/tex]

Also  

    [tex]\frac{CA}{sin (32)} =  \frac{467.3 }{sin (107.8)}[/tex]

    [tex]CA = 260 .1 \ miles [/tex]

Generally the additional flyer miles that Adam will receive if he takes the connecting flight rather than the direct​ flight is mathematically represented as

      [tex]k = [CA +BC]  - AB [/tex]

=>     [tex] k = [260 .1 +316.8]- 467.3 [/tex]

=>  [tex] k =109.6 \ miles [/tex]

Answer:

(6, 7)

Step-by-step explanation:

Hope this helps.

The midpoint of the line segment AB is M. Then the coordinate of the point B will be (6, 7).

Let AB be the line segment and C be the mid-point of line segment AB. Let the coordinate of point A (x₁, y₁), the coordinate of point B (x₂, y₂), and the coordinate of the mid-point (x, y).

Then the coordinate of the mid-point of the line segment is given as,

(x, y) = [(x₁ + x₂) / 2, (y₁ + y₂) / 2]

The midpoint of AB is M(4,4). If the coordinates of A are (2, 1). Then the coordinate of the point B will be given as,

(x, y) = [(x₁ + x₂) / 2, (y₁ + y₂) / 2]

(4, 4) = [(2 + x₂) / 2, (1 + y₂) / 2]

Compare the abscissa, then we have

(2 + x₂) / 2 = 4

(2 + x₂) = 8

x₂ = 8 - 2

x₂ = 6

Compare the ordinate, then we have

(1 + y₂) / 2 = 4

1 + y₂ = 8

y₂ = 8 - 1

y₂ = 7

The midpoint of the line segment AB is M. Then the coordinate of the point B will be (6, 7).

More about the mid-point of the line segment link is given below.
