A drug company testing a pain medication wants to know the impact of different dosages on patients' pain
levels. They recruited volunteers experiencing pain to try one of 6 different dosages and then rate their pain
levels on a scale of 1 to 10. Here are the results:

Answer: The winning time increased by an average of 0.4 second per year from year 2 to year 4.

The winning time for a race displayed in the table would be:

C). The winning time increased by an average of 0.4 seconds per year from year 2 to year 4.

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Find the increase in winning time:

Given that,

Year                             Winning Time(seconds)

1                                          27.5

2                                         28.4

3                                         28.7

4                                         29.2

5                                         29.44

Hence, The total change in the time is,

= (0. + 0.3 + 0.5 + 0.24)/4

= 0.485 seconds

Now, If we round off, it becomes 0.5 seconds.

Therefore, it can be considered that an average of 0.5 seconds changes every year from year 2 to 4.

Thus, ''Option C'' is the correct answer.

Step-by-step explanation:

first, distribute 7 to 6m (this means 7 • 6m)

7 • 6m = 42m

then distribute 7 to 7 (which is 7 • 7)

7 • 7 = 49

your simplified expression is 42m + 49. i hope this helps! have a great day <3

Answer:

Barry's drawing is  5.5 in  tall and 2.5 in wide.

Step-by-step explanation:

We are given that

Height of tree, h=11 in

Width of tree, b=5 in

We have to find the size of the original.

Size of drawing is 1/2 size of the original

Therefore,

Height of drawing, h'=[tex]\frac{1}{2}\times 11[/tex]in

Height of drawing, h'=5.5 in

Width of drawing tree=[tex]\frac{1}{2}\times 5[/tex]

Width of drawing tree=[tex]2.5in[/tex]

Hence, Barry's drawing is  5.5 in  tall and 2.5 in wide.

Answer:

x = -2

Step-by-step explanation:

Answer:

Five domain values of the function f(x) = x² - 1, are; 1, 2, 3, 4, 5

Five range values of the function f(x) = x² - 1, are; 0, 3, 8, 15, 24

Step-by-step explanation:

The values in the domain are the values of the independent or (normally) x-variable

The values i the range are the values obtained by applying the function relationship to the domain as follows;

Let 'f(x)' represent the function that generates the values of the data in the data set,

For f(x) = x² - 1, we have the following table;

[tex]\begin{array}{ccc}x&f(x)\\1&0\\2&3\\3&8\\4&15\\5&24\end{array}[/tex]

Therefore;

The function is f(x) = x² - 1

The five domain values are; 1, 2, 3, 4, 5

The five range values are; 0, 3, 8, 15, 24.

C: Life insurance policy amounts should factor in how much it would take to maintain the standard  of living for the beneficiaries

Step-by-step explanation:

The statement is true for life insurance coverage

Answer:

c is answer plz see the pic it's the solution

Answer:

2s+3b=154

s=2b

solving: s= 44, b= 22

Step-by-step explanation:

s=number of sundaes sold

b=number of banana splits sold

2s+3b=154

s=2b

to solve:

substitute s=2b into the first equation

2(2b)+3b=154

4b+3b=154

7b=154

divide both sides by 7

7b/7=154/7

b=22

s=44

Answer:

B

Step-by-step explanation:

7 - a + 3

subtract 7 from both sides.

-a = 3 - 7

add like terms (3 + - 7)

-a = -4

divide both sides by -1. (remember that in front of the a, a 1 is there.)

a = 4

answer: b. 4

Answer:

The sprinkler will cover an area of [tex]50m^2[/tex]

Step-by-step explanation:

Given

[tex]Area = 240m^2[/tex]

[tex]\theta = 75^{\circ}[/tex]

Required

Determine the amount of area it can cover

The amount of area is calculated by calculating the area of a sector using:

[tex]Sector\ Area =\frac{\theta}{360^{\circ}} * \pi r^2[/tex]

Where:

[tex]Area = \pi r^2 = 240m^2[/tex]

So, we have:

[tex]Sector\ Area =\frac{\theta}{360^{\circ}} * 240m^2[/tex]

Substitute 75 for [tex]\theta[/tex]

[tex]Sector\ Area =\frac{75^{\circ}}{360^{\circ}} * 240m^2[/tex]

[tex]Sector\ Area =\frac{75^{\circ}* 240m^2}{360^{\circ}}[/tex]

[tex]Sector\ Area =\frac{75* 240m^2}{360}[/tex]

[tex]Sector\ Area =\frac{18000m^2}{360}[/tex]

[tex]Sector\ Area =\frac{18000}{360} m^2[/tex]

[tex]Sector\ Area =50m^2[/tex]

Hence, the sprinkler will cover an area of [tex]50m^2[/tex]

Responder:

240 huevos

Explicación paso a paso:

Número de cajas de huevos = 4

Huevos por caja = 50

Total de huevos en caja = 50 * 4 = 200 huevos

Número de cajas = 3

Número de huevos por caja = 10

Total de huevos en caja = 10 * 4 = 40 huevos

Huevos totales = (huevos en caja + huevos en cartón)

Total = (200 + 40) = 240 huevos
