have an amazing day <3

Answer:

No it is not a factor

Step-by-step explanation:

Reason for not being a factor is 3x^3-4x^2-4x. 3x3−4x2−4x 3 x 3 - 4 x 2 - 4 x. Factor x x out of 3x3−4x2−4x 3 x 3 - 4 x 2 - 4 x

Answer:

3 seconds.

Step-by-step explanation:

First calculate the time for each 20m length to pass through the bridge.

The train takes 3600 seconds to travel 144,000 m

So it takes 3600/144000 seconds to travel 1m.

and 3600 * 20 / 144000 seconds to travel 20 m.

As the train is 120 m long  and there are 6 * 20 m in 120m the answer is:

3600 * 20 * 6 / 144000 seconds.

= 3 seconds.

c. The sports marketing company can be 90% confident that the constructed interval captures the true mean number of hours teens from this town watch sports.

Step-by-step explanation:

got it right on edge

The statement third "sports marketing company can be 90% confident that the constructed interval captures the true mean number of hours teens from this town watch sports" is the correct.

It is defined as the measure of data disbursement, It gives an idea about how much is the data spread out.

First, we will find the 90% confidence interval:

We have:

X = 6.25 hours, SD =4.33 hours, n = 40

90% confidence interval:

= (X±t×s/√n)

For 90% confidence interval:

t = t(n-1), 1-α/2 = t(39), 0.95 = 1.685

After putting all the values in the above confidence interval, formula:

We get:

Confidence interval = (5.097, 7.404)

Thus, the statement third "sports marketing company can be 90% confident that the constructed interval captures the true mean number of hours teens from this town watch sports" is the correct.

Answer:

The tree is about 62ft tall

Step-by-step explanation:

sin(62)=x/70

70sin(62)=x

61.8=x

Answer:

4 ft higher

Step-by-step explanation:

Since the ladder is 10 ft long and its top is 6 feet high(above the ground), we find the distance of its base from the wall since these three (the ladder, wall and ground) form a right angled triangle. Let d be the distance from the wall to the ladder.

So, by Pythagoras' theorem,

10² = 6² + d²  (the length of the ladder is the hypotenuse side)

d² = 10² - 6²

d² = 100 - 36

d² = 64

d = √64

d = 8 ft

Since the ladder is moved so that the base of the ladder travels toward the wall twice the distance that the top of the ladder moves up.

Now, let x be the distance the top of the ladder is moved, the new height of top of the ladder is 6 + x. Since the base moves twice the distance the top of the ladder moves up, the new distance for our base is 8 - 2x(It reduces since it gets closer to the wall).

Now, applying Pythagoras' theorem to the ladder with these new lengths, we have

10² = (6 + x)² + (8 - 2x)²

Expanding the brackets, we have

100 = 36 + 12x + x² + 64 - 32x + 4x²

collecting like terms, we have

100 = 4x² + x² + 12x - 32x + 64 + 36

100 = 5x² - 20x + 100

Subtracting 100 from both sides, we have

100 - 100 = 5x² - 20x + 100 - 100

5x² - 20x = 0

Factorizing, we have

5x(x - 4) = 0

5x = 0 or x - 4 = 0

x = 0 or x = 4

The top of the ladder is thus 4 ft higher

A truth table is a way of organizing information to list out all possible scenarios. We title the first column p for proposition. In the second column we apply the operator to p, in this case it's ~p (read: not p). So as you can see if our premise begins as True and we negate it, we obtain False, and vice versa.

Answer:

the one with the most parts citric acid

Step-by-step explanation:

no tables were provided but if a cup is 3/4 water and 1/4 citric acid and the other is 1/4 water and 3/4 citric acid then it's the second one. Basically it the one with the most citric acid.

Answer:

3

Step-by-step explanation:

first of all, 8 pints=1 gallon

multiply 4 by the number of days which is 30 so you get 120. then divide by 8 (pints) to find the number of gallons. you come out with 15 gallons. each tank has 5 gallons, so 15 divided by 5 is 3.

Answer:

Rachel worked for [tex]3\frac{2}{3}[/tex] hours

Step-by-step explanation:

See comment for complete question

Given

Let

[tex]D = Dominic[/tex]

[tex]R = Rachel[/tex]

So:

[tex]D = 2\frac{3}{4}[/tex]

and

[tex]R =1\frac{1}{3}[/tex] as long as D

Required

Determine the number of hours spent by Rachel

This implies that:

[tex]R =1\frac{1}{3}[/tex] as long as D

Rewrite as:

[tex]R =1\frac{1}{3} * D[/tex]

Substitute: [tex]D = 2\frac{3}{4}[/tex]

[tex]R =1\frac{1}{3} * 2\frac{3}{4}[/tex]

Express as improper fraction

[tex]R =\frac{4}{3} * \frac{11}{4}[/tex]

This gives:

[tex]R =\frac{1}{3} * 11[/tex]

[tex]R =\frac{11}{3}[/tex]

Express as mixed numbers

[tex]R =3\frac{2}{3}[/tex]

Hence, Rachel worked for [tex]3\frac{2}{3}[/tex] hours

Answer:

113.04 is our answer

Step-by-step explanation:

When finding Area the formula to do so is

radius x radius x pi

Sense we arent given radius we have to find out whats the radius but we must remember radius is just half of the diameter so since we are given diameter we will just do diameter divided by 2 so 12 ÷ 2 = 6 now that we have are radius we square it thats just a fancy way of saying multiply by itself so 6 x 6 = 36 now we multiply 36 with 3.14 So

3.14 x 36 = 113.04 So c is our answer!

Step-by-step explanation: Hope this help :D

Let the speed of the first plane be x then the speed of the second plane would be x + 30

The combined speed is x + x + 30 = 2x + 30

2x + 30 = 380

Subtract 30 from both sides

2x = 350

Divide both sides by 2

X = 175

The speed of the first plane was 175 miles per hour the speed of the second plane was 205 hour

16-11-13-5-10 => P-K-M-E-J

2-15-18 => B-O-R

13-23 = > M-W

8-11-17 => H-K-Q

11-12 => K-L

22-11-12-19 => V-K-L-S

Step-by-step explanation:

2-15-18

13-23

8-11-17

11-12

22-11-12-19

From the code key, we can see that each number represent the alphabet at that position;

To do this, we simply replace each number with the alphabet they represent.

So, we have:

16-11-13-5-10 => P-K-M-E-J

2-15-18 => B-O-R

13-23 = > M-W

8-11-17 => H-K-Q

Answer:

x= 3, y= 4

Step-by-step explanation:

y= 3x -5 -----(i)

y= -x +7 -----(ii)

Substitute (i) into (ii):

3x -5= -x +7

3x +x= 7 +5

4x= 12

x= 12 ÷4 (÷4 on both sides)

x= 3

Substitute x= 3 into (ii):

y= -3 +7

y= 4

Answer:

The square root will be about 4 because the formula for square root is √(x^2) = x

Step-by-step explanation:

Answer:

√18 = √(2x9) = 3√2. so they pulled the 2 out of the square root incorrectly.

4x4 = 16

5x5 = 25

so √18 is between 4 and 5. closer to 4
