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

Answer:

6.4/6

Step-by-step explanation:

Since

4 : 5 = X : 8

Then we know

4/5 = X/8

Multiplying both sides by 8 cancels on the right

8 × (4/5) = (X/8) × 8

8 × (4/5) = X

Then solving for X

X = 8 × (4/5)

X = 6.4

Therefore

4 : 5 = 6.4 : 8

Answer:

(7 miles)/(50 minutes) = (x miles)/(75 minutes)

7/50 = x/75

7*75 = 50x

525 = 50x

50x = 525

x = 525/50

x = 10.5

He can run 10.5 miles in 75 minutes

Step-by-step explanation:

Answer:

10 [tex]\frac{1}{2}[/tex] miles in 75 minutes.

Step-by-step explanation:

Let us first analyze the problem,

we are given that she runs 7 miles in 50 mins

make it a fraction

[tex]\frac{7}{50}= \frac{x}{75}[/tex]     (we cross multiply)

525=50x   (divide both sides by 50)

x=10.5      (x= the amount of miles)

The function is

The remainder when f(x) is divided by x−2 is 23

To find:

The value of k.

Solution:

According to the remainder theorem, if a polynomial P(x) is divided by (x-c), then the remainder is P(c).

It is given that, the remainder when f(x) is divided by x−2 is 23. By using the remainder or theorem, we get  

Put x=2, to find the value of f(2)

Using (i) and (ii), we get

Therefore, the value of k is 8.

Step-by-step explanation:

hope this helps

f(x) - 2x³ + kx - 4 and the remainder when f(x) is divided by x + 2 is -18.  then k is 15.

The remainder theorem states that when a polynomial p(x) is divided by (x - a), then the remainder = f(a)

f(x)=2x³ + kx - 4

x+2=0

x=-2

By the remainder theorem, the remainder when dividing by x-a is f(a)

f(-2)=2(-2)³+k(-2)-4

=-2(-8)-2k-4

=16-2k-4

The remainder is -18.

So, 16-2k-4=-18

12-2k=-18

-2k=-18-12

-2k=-30

k=15

Hence the value of k is 15.

Answer:

50° is the correct answer

Step-by-step explanation:

Right Triangles

The right triangles are identified because they have an internal angle of 90°. The basic trigonometric ratios can be used to find angles and side lengths as needed.

We have a right triangle with the following characteristics:

The hypotenuse is 13 units long

The indicated angle is opposite to the leg of 10 units long.

When we know the length of the opposite side, we use the sine ratio. Let's call θ to the required angle:

[tex]\displaystyle \sin\theta=\frac{\text{opposite side}}{\text{hypotenuse}}[/tex]

[tex]\displaystyle \sin\theta=\frac{10}{13}[/tex]

Using a calculator set in mode degrees, the angle is:

[tex]\theta=\sin^{-1}\frac{10}{13}[/tex]

[tex]\theta\approx 50.3^\circ[/tex]

First choice: 52° is not correct because is not a good approximation to 50.3°

Second choice:38° is not correct because is not a good approximation to 50.3°

Third choice: 50° is a good approximation to 50.3°. Correct Answer

Fourth choice: 40° is not correct because is not a good approximation to 50.3°

Answer:

[tex]y = - \frac{9}{8} x + 7[/tex]

Step-by-step explanation:

[tex]m = \frac{ - 2 - 7}{8 - 0} = \frac{ - 9}{8} [/tex]

Since this line passes through (0,7), then this point satisfies the equation of the line;

[tex]y = \frac{ - 9}{8} x + b[/tex]

[tex]7 = \frac{ - 9}{8} (0) + b[/tex]

[tex]7 = b[/tex]

[tex]b = 7[/tex]

Hey there!

We are given 2 points that the line passes through, so we can easily determine the slope of the line:

[tex]\bold{\displaystyle\frac{y2-y1}{x2-x1} }[/tex]

[tex]\bold{\displaystyle\frac{-2-7}{8-0}=\frac{-9}{8} }[/tex]

So now we have the slope.

However, we also need to find the y-intercept (we are actually given the y-intercept, (0,7) or just 7)

Hence, the equation is

[tex]\boxed{\boxed{\bold{y=-\frac{9}{8} x+7}}}[/tex]

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).

The total number ot turbans that Lisa's inventory should have 9 turbans in the next 18 hats when requested, under the condition that recently lent out a number of different hats. ski hats 4 berets 1 turban.

The evaluated probability of turbans in Lisa's inventory is 5/10 or 1/2. This projects that out of every 10 hats in Lisa's inventory, 5 are turbans.
To evaluate the expected number of turbans in the next 18 hats taken from Lisa's inventory, we can apply  the formula:
Expected number of turbans = Probability of turbans × Total number of hats requested

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.
