Answer:

5.45%

Step-by-step explanation:

Given:

An airline ticket states that the flight takes 2 hours and 45 minutes.

The flight time is actually 2 hours and 54 minutes.

Question asked:

What is the percent error in the flight time?

Solution:

As we know:

[tex]Percent\ error=\frac{Experimental\ value - Theoretical\ value}{ Theoretical\ value}} \times100[/tex]

Theoretical value = 2 hours and 45 minutes

1 hour = 60 minutes

2 hours 45 minutes = 60 [tex]\times[/tex] 2 + 45 = 120 + 45 = 165 minutes

Experimental value = 2 hours and 54 minutes

1 hour = 60 minutes

2 hours 54 minutes = 60 [tex]\times[/tex] 2 + 54 = 120 + 54 = 174 minutes

[tex]Percent\ error=\frac{174-165}{165} \times100\\ \\ Percent\ error=\frac{9}{165} \times100\\ \\ Percent\ error=\frac{900}{165} \\ \\ Percent\ error=5.45[/tex]

Thus, the percent error in the flight time is 5.45%

Answer:

[tex]V=753.6\ \text{inches}^3[/tex]

Step-by-step explanation:

Given that,

Radius of a paint can, r = 4 inches

Height of a paint can, h = 15 inches

We need to find the volume of the paint can. We know that the shape of a paint can is in the form of cylinder such that the volume of cylinder is given by :

[tex]V=\pi r^2h[/tex]

Substituting all the values we get

[tex]V=3.14\times (4)^2\times 15\\\\V=753.6\ \text{inches}^3[/tex]

So, the volume of the paint can is 753.6 cubic inches.

∠ b = 132°

Step-by-step explanation:

Since v and w are parallel.

The angle vertically opposite 48° is congruent , thus = 48°

b and 48° are same- side interior angles and supplementary, thus

b = 180° - 48° = 132°

x1,x2(-1, 7/3)

to slove this you need the formula

from equation a=3 b=-4 c=7;

x=(-b±√b²-4ac)/2a

x=(4±√-4²-4×3×7)/2×3

x=(4±√100)/6

x=(4±10)/6

x1=4-10/6 x2=4+10/6

x1=-6/6 x2=14/6

x1=-1 x2=7/3

The sum of roots is 4/3, and the product of roots is -7/3 for the quadratic equation [tex]3x^2[/tex] - 4x - 7 = 0.

To find the sum and product of the roots of the quadratic equation [tex]\(3x^2 - 4x - 7 = 0\)[/tex], we can use Vieta's formulas.

Vieta's formulas state that for a quadratic equation of the form [tex]\(ax^2 + bx + c = 0\),[/tex] the sum of the roots [tex](\(r_1\) and \(r_2\))[/tex] is given by [tex]\(-\frac{b}{a}\),[/tex] and the product of the roots is given by [tex]\(\frac{c}{a}\).[/tex]

In your equation, [tex]\(a = 3\), \(b = -4\), and \(c = -7\).[/tex]

So, the sum of the roots [tex](\(r_1\) and \(r_2\)) is:[/tex]

[tex]\[r_1 + r_2 = -\frac{b}{a} = -\frac{-4}{3} = \frac{4}{3}\][/tex]

And the product of the roots [tex](\(r_1\) and \(r_2\)) is:[/tex]

[tex]\[r_1 \cdot r_2 = \frac{c}{a} = \frac{-7}{3}\][/tex]

So, the sum of the roots is [tex]\(\frac{4}{3}\)[/tex], and the product of the roots is [tex]\(\frac{-7}{3}\).[/tex]

In a square, all four sides are the same length. Imagine a square that has been cut by a diagonal. We have two triangles, each with the same length hypotenuse (diagonal length) and two equal side lengths. To find the length of each side, we can use the Pythagorean theorem.

I used x in place of a and b, as both side lengths are equal.

x^2 + x^2 = (28 [tex]\sqrt{2}[/tex])^2

2x^2 = 1568

x^2 = 784

x = 28

The length of each side is 28 units.

Hope this helps!! :)

Answer:

Once it is a square, the lengths are the same. Considering that

a square's diagonal is [tex]s\sqrt{2}[/tex], thus, each length measures 28.

You may use the pythagorean theorem:

[tex](28\sqrt{2} )^2=s^2+s^2\\28\sqrt{2} =\sqrt{s^2+s^2} \\28\sqrt{2} =s\sqrt{2} \\[/tex]

Answer:

Andrew has 9 cars

Step-by-step explanation:

Let's start by defining what our unknowns are and how to name them:

For the number of cars Andrew has: let's use the letter A

For the number of cars Luke has: let's use the letter L

Not write the first sentence in mathematical terms:

"Luke has 4 more than triples the number of cars that Andrew has."

L = 3 * A + 4

The second phrase results on a very simple equation since it just states the number of cars that Luke has:

L = 31

Now we can combine these two equations by replacing the variable "L" in the first equation with the second equation and then solve for A:

L = 3 * A + 4

31 = 3 * A +4

31 - 4 = 3 * A

27 = 3 * A

A = 27/3

A = 9

Therefore, Andrew has 9 cars.

Answer:

No

Step-by-step explanation:

No, the given list does not represent a complete probability model because the sum of the probabilities is not equal to 1.

The sum of probabilities should always equal to 1 in a complete probability model. In this case, the sum of probabilities is 16 + 13 + 112 + 12 = 153, which is not equal to 1. Therefore, it is not a complete probability model.

Final answer:

The provided list does not form a complete probability model because the probabilities do not sum up to 1, and some values exceed 1, which is not possible for probabilities.

Explanation:

The list provided does not represent a complete probability model because the probabilities of all possible outcomes of a probability model must sum up to 1. However, the sum of the probabilities listed (P(red) = 16, P(yellow) = 13, P(blue) = 1/12, and P(green) = 1/2) does not equal 1. The values for P(red) and P(yellow) seem to be mistakes or typos, as probabilities cannot be greater than 1. If these values were supposed to represent fractions and perhaps there are typos, they may need correcting to ensure the probabilities would sum up to 1. An example of a complete probability model can be seen in the jelly bean question mentioned, where the probabilities of selecting each color are fractions that sum up to 1.

common factor= adding by 2

2n+3

find the 30th term

2×30+3=63

answer= 63

The 30th term of the linear sequence −5, −7, −9, −11, −13, . . . is -63. This is found using the formula for the nth term of a linear sequence, which is expressed as nth term = first term + (n - 1)*common difference.

The 30th term of a linear sequence can be found using the formula: nth term = first term + (n - 1)*common difference. In this sequence, the first term is -5 and the common difference (distance between each term) is -2 (since -7 minus -5 equals -2).

By substituting the appropriate values into the formula, we get: 30th term = -5 + (30 - 1)*(-2) = -5 - 58 = -63. Therefore, the 30th term of the sequence is -63.

Step-by-step explanation:

[tex] \frac{44 + 47 + y + 58 + 55}{5} = 52[/tex]

[tex] \frac{204 + y}{5} = 52[/tex]

[tex]204 + y = 260[/tex]

[tex]y = 56[/tex]

The value of y is 56.

Arithmetic mean is often referred to as the mean or arithmetic average. It is calculated by adding all the numbers in a given data set and then dividing it by the total number of items within that set. Mean is the most commonly used measure of central tendency. It represents the average of the given collection of data.

Given here, the observations are 44,47,y,58,55 and the given mean is 52

then we can construct the equation:

44+47+y+58+55 /5 = 52

 (y + 204) / 5           = 52

             y + 204        =260

                      y          =  56

Hence, The value of y is 56

By using the conversion factor that 1 fluid ounce is equal to 2 tablespoons, an 11 fluid ounce can of orange juice contains 22 tablespoons of juice.

To find out how many tablespoons of juice are in a can, we will use the given conversion factors. We know that 1 fluid ounce (fl oz) is equivalent to 2 tablespoons (tbsp). The can contains 11 fluid ounces of orange juice.

Therefore, there are 22 tablespoons of orange juice in a can.

Answer:

93.76%

Step-by-step explanation:

93.76% should be your new grade

I'm not 100% sure but what I did is that I divided each percent you have by it's worth. So for example, 96% x 20% = 0.192

I did this with all the possible percents and then I made them into whole number. So the 0.192 became 192. Here I divided it by 5. I should've divided by 4 but since the project is a 0% I didn't have to add it, just use it to divide.

So here I had 117.2 then I multiplied it by 80% because that's the total percent all those grades equaled and got 93.76%
