The total number of hours tea that Trent has practiced his guitar after D days is modeled by the equation shown t=3d

Answers

Answer:

The complete table is

d               t

1               3

3              9

5              15

Step-by-step explanation:

Here is the correct and complete question:

The total number of hours, t, that Trent has practiced his guitar after d days is modeled by the equation t = 3d.

Complete the table below.

d               t

1

3

               15

Step-by-step explanation:

For the first space, we are to determine the value of t when d is 1

From the given equation, t = 3d, put d = 1 and determine t

t = 3d

∴ t = 3(1) = 3×1

t = 3

For the second space , we are to determine the value of t when d is 3

Put d = 3 in the equation to determine t

t = 3d

∴ t= 3(3) = 3×3

t = 9

For the third space, we are to determine the value of d when t is 15.

Put t = 15 in the equation and then find d

t = 3d

∴ 15 = 3d

Divide both sides by 3

15/3 = 3d/3

5 = d

∴ d = 5

Brian recorded the number of commercials played during two types of television shows: an educational documentary and a primetime drama. Both types of shows lasted 1 hour, including commercials. He recorded the number of commercials for 10 episodes of each type of show.

Answers

Answer:

[tex]m(x)_A = 5.2[/tex] --- Mean absolute deviation of educational documentary

[tex]m(x)_B = 4.7[/tex] --- Mean absolute deviation of prime time drama

Step-by-step explanation:

Given

[tex]n = 10[/tex]

See attachment for table

Required

Determine the mean absolute deviation of each

Mean absolute deviation m(x) is calculated as:

[tex]m(x) = \frac{1}{n}\sum |x - \mu|[/tex]

For Educational Documentary

First, calculate the mean

[tex]\mu = \frac{\sum x}{n}[/tex]

So:

[tex]\mu_A = \frac{26 + 28 + 30 + 18+27 + 18 + 20 +31+17+17}{10}[/tex]

[tex]\mu_A = \frac{232}{10}[/tex]

[tex]\mu_A = 23.2[/tex]

The mean absolute deviation is then calculated as:

[tex]m(x)_A = \frac{1}{n}\sum |x - \mu_A|[/tex]

[tex]m(x)_A = \frac{1}{10}(|26 -23.2| +|28 -23.2| +|30 -23.2| +|18 -23.2| +|27 -23.2| +|18 -23.2| +|20 -23.2| +|31 -23.2| +|17 -23.2| +|17 -23.2|)[/tex]

[tex]m(x)_A = \frac{1}{10}(|2.8| +|4.8| +|6.8| +|-5.2| +|3.8| +|-5.2| +|-3.2| +|7.8| +|-6.2| +|-6.2|)[/tex]

[tex]m(x)_A = \frac{1}{10}(2.8 +4.8 +6.8 +5.2 +3.8 +5.2 +3.2 +7.8 +6.2 +6.2)[/tex]

[tex]m(x)_A = \frac{1}{10}*52[/tex]

[tex]m(x)_A = 5.2[/tex]

For Prime time Drama

First, calculate the mean

[tex]\mu = \frac{\sum x}{n}[/tex]

So:

[tex]\mu_B = \frac{39+39+35+29+40+27+41+29+32+30}{10}[/tex]

[tex]\mu_B = \frac{341}{10}[/tex]

[tex]\mu_B = 34.1[/tex]

The mean absolute deviation is then calculated as:

[tex]m(x)_B = \frac{1}{n}\sum |x - \mu_B|[/tex]

[tex]m(x)_B = \frac{1}{10}(|39-34.1|+|39-34.1|+|35-34.1|+|29-34.1|+|40-34.1|+|27-34.1|+|41-34.1|+|29-34.1|+|32-34.1|+|30-34.1|)[/tex]

[tex]m(x)_B = \frac{1}{10}(|4.9|+|4.9|+|0.9|+|-5.1|+|5.9|+|-7.1|+|6.9|+|-5.1|+|-2.1|+|-4.1|)[/tex]

[tex]m(x)_B = \frac{1}{10}(4.9+4.9+0.9+5.1+5.9+7.1+6.9+5.1+2.1+4.1)[/tex]

[tex]m(x)_B = \frac{1}{10}*47[/tex]

[tex]m(x)_B = 4.7[/tex]

Answer:

The 3rd answer

Step-by-step explanation:the

180-30\2

....

=75

30+2*75=

...

180

Answer:

30 + 2x = 180

Step-by-step explanation:

This is becuase we know this triangle is an isosceles triangle. (The two markings on the sides prove that.) An isosceles triangle is when two sides (so naturally also two angles) are the same. This means the other angle is x. We know that if we add all of the angles, we'll get 180. So, 30 + x + x = 180 or "30 + 2x = 180".

Also, x = 75.

Here:

30 + 2x = 180

30 - 30 + 2x = 180 - 30

2x = 150

2x / 2 = 150 / 2

x = 75

What package is the Best Buy?

Answers

Answer: The answer is 8 lb for $18.80

That is the answer because you have to divide in order to see which is the best buy

You have to divide $4.98 by 2lb and you will get 2.49, divide $12.25 by 5lb which equals 2.45, divide $18.80 and you will get 2.35, divide $23.70 by 10lb and you will get 2.37. So therefore you answer is C.8lb for $18.80 because 2.35 is better than the other deals.

What equation models the data in the table if d = number of days and c = cost?

Days
2
3
5
6
Cost
44
66
110
132

A. c = d + 22

B. c = 22d

C. d = 22c

D. c = d + 22d

Answers

Answer:  B. c = 22d

I'm gonna go with c=22d

Step-by-step explanation:  22d

C = 22d is the correct answer because for every day the cost increases by 22 so two days mean the cost is equal to 22 (2)

...............................................................................................................................................

Answer:

The equation that models the data in the table is:

                       

Step-by-step explanation:

The table that represent the days and cost is given by:

      Days Cost

          2          44

          3          66

          5           110

          6          132

We see that the cost is a constant multiple of  the number of days.

i.e. the equation is given by:

            c=22d

i.e. the relationship is linear.

( Since, when d=2

we have: c=22×2=44

when d=3 we have:

c=22×3=66

and so on )

...............................................................................................................................................

You can see that 44/2 = 22

66/3 = 22

110/5 = 22

132/6 = 22

Then, the relation between C and d is a constant.

C/ d = 22

And you can model C as:

C = 22d.

This model tells that the cost equals 22 times the days.

?????????????????????

Answers

Step-by-step explanation:

the total angles of the triangle are 180°

so,

180° = (x - 10) + (2x + 5) + 35°

180° - 35° = (x - 10) + (2x + 5)

145° = 2x + x + 5 - 10

145° = 3x - 5

145° + 5 = 3x

150° = 3x

150/3 = x

x = 50

Although it is now extinct, the Carolina parakeet was last seen in Florida in 1920. Back then, large areas of habitat were logged and converted to agricultural fields. Honeybees evicted the parakeets from hollow trees where they nested. Many parakeets were shot for food and their feathers. In addition, farmers shot the parakeets to keep them from eating their seeds. What can you conclude from these observations about why the Carolina parakeet became extinct?
a.Extinction may be the result of several factors.

b.Extinction is always the result of human activity.

c.Extinction occurs when an organism adapts to changes in its environment.

Luke wants to cover this wall with blue paint.

1.6 m
3.6 m
wall
door
6.1 m
He will buy blue paint in 2.5 litre tins.
Each 1 litre of blue paint will cover 8 m2 of the wall.
How many tins of blue paint does Luke need to buy?

Answers

First find the area of the wall by splitting it into two rectangles

The first rectangle is 7m x 1.6m=11.2m²

The second is (3.6m-1.6m) x 6.1m= 2m x 6.1m= 12.2m²

11.2m² + 12.2m²= 23.4m²


2.5 litres
1litre covers 8m²
So 2.5 x8 =20m ² covered by 2.5 litres

23.4 ÷ 20 =1.17 tins

So Luke needs to buy 2 tins of blue paint
