Let A = {6, 2, 3, 4}, B = {5, 2, 3}, and C = {1, 2, 3}. Find each of the following sets.

Answer:

B

Step-by-step explanation:

Subtract $1.95 from $12 to account for the flat rate that Jason must pay, then divide that by 0.55, or the per mile charge. The answer, or the highest amount of miles he can go with $12, is 18.27272727. The answer that best represents the number of miles he can go is B because he can go up to 18 miles, including 18 miles, hence the closed circle.

The multiplication 3/4×8/9 can be used to address the problem in response (B). which is the correct answer that would be an option (B).

In mathematics, Multiplication operations perform Multiplying values on either side of the operator.

For example 4×2 = 8

As per option (B),

Jada rode her bike for 3/4 mile. Sarah rode her bike 8/9 the distance that Jada rode her bike.

Sarah rides her bike = Sarah rode (8/9) of the (3/4) that Jada rode.

Sarah rides her bike = 3/4 × 8/9

Therefore, this problem can be solved by performing the above multiplication.

Hence, the correct answer would be an option (B).

Answer:

100

Step-by-step explanation:

The total amount Tom saved per month is equal to \(\£ 220\) (nearest \(\£10\)).

" Amount is defined as the total of all the given quantities as per given conditions."

According to the question,

The amount required to pay for a visa \(= \£ 2,400\)

Percentage charges on the visa price as day service\(= 8\%\)

Amount as day charge  \(= 8\%\) of \(2400\)

                                        \(= \frac{8}{100} \times 2400\\\\= \£192\)

The total amount required for a visa \(= \£ (2400 + 192)\)

                                                             \(= \£ 2592\)

Tom has one year to save,

Therefore,

Amount Tom save in one month  \(= \frac{2592}{12}\)

                                                        \(=\£ 216\)

                                                        ≈\(\£ 220\) ( round to nearest \(\£ 10\))

Hence, the total amount Tom saved per month is equal to \(\£ 220\) (nearest \(\£10\)).

Answer:

3.6 × 10^9

Step-by-step explanation:

When multipliying two numbers in scientific notation, the exponents in the factor of 10 will be added when the two expressions are multiplied.

Thus (1.2 ⋅ 10^28) ⋅ (3 ⋅ 10^−19) = ( 1.2 × 3 )

( 10^28 × 10^-19 ) = 3.6 × 10^(28-19) = 3.6 × 10^9

Answer:

The solution of the problem is \(y(t) = e^{2 t} cos(2 t)\)

Step-by-step explanation:

First we will write the characteristic equation which is

\(x^{2} -4x + 8 = 0\)

Now, we will solve this quadratic equation using the general formula.

Given a quadratic equation of the form, \(ax^{2} +bx +c = 0\), then

From the general formula,

\(x = \frac{-b+\sqrt{b^{2}-4ac } }{2a}\) or \(x = \frac{-b-\sqrt{b^{2}-4ac } }{2a}\)

From the characteristic equation, \(a = 1, b = -4,\) and \(c = 8\)

Hence,

\(x = \frac{-(-4)+\sqrt{(-4)^{2}-4(1)(8) } }{2(1)}\) or \(x = \frac{-(-4)-\sqrt{(-4)^{2}-4(1)(8) } }{2(1)}\)

\(x = \frac{4+\sqrt{-16} }{2}\) or \(x = \frac{4-\sqrt{-16} }{2}\)

\(x = \frac{2+4i }{2}\) or \(x = \frac{2-4i }{2}\)

\(x = 2 + 2i\) or \(x = 2 - 2i\)

That is, \(x\) =  \(2\) ± \(2i\)

Then, \(x_{1} = 2 + 2i\) and \(x_{2} = 2 - 2i\)

These are the roots of the characteristic equation

The roots of the characteristic equation are complex, that is, in the form

(\(\alpha\) ± \(\beta i\)).

For the general solution,

If the roots of a characteristic equation are in the form  (\(\alpha\) ± \(\beta i\)), the general solution is given by

\(y(t) = C_{1}e^{\alpha t} cos(\beta t) + C_{2}e^{\alpha t} sin(\beta t)\)

From the characteristic equation,

\(\alpha = 2\) and \(\beta = 2\)

Then, the general solution becomes

\(y(t) = C_{1}e^{2 t} cos(2 t) + C_{2}e^{2 t} sin(2t)\)

Now, we will determine \(y'(t)\)

\(y'(t) = 2C_{1}e^{2 t} cos(2 t) - 2C_{1}e^{2t}sin(2t) + 2C_{2} e^{2t}sin(2t) +2C_{2}e^{2t}cos(2t)\)

From the question,

y(0) = 1

and

y'(0) = 2

Then,

\(1 = y(0) = C_{1}e^{2 (0)} cos(2 (0)) + C_{2}e^{2 (0)} sin(2(0))\)

\(1 = C_{1}e^{ 0} cos(0) + C_{2}e^{0} sin(0)\)

(NOTE: \(e^{0} = 1, cos(0) = 1\) and \(sin(0) = 0\) )

Then,

\(1 = C_{1}\)

∴\(C_{1} = 1\)

Also,

\(2 = y'(0) = 2C_{1}e^{2 (0)} cos(2 (0)) - 2C_{1}e^{2(0)}sin(2(0)) + 2C_{2} e^{2(0)}sin(2(0)) +2C_{2}e^{2(0)}cos(2(0))\)\(2 = 2C_{1}e^{0} cos(0) - 2C_{1}e^{0}sin(0) + 2C_{2} e^{0}sin(0) +2C_{2}e^{0}cos(0)\)

\(2 = 2C_{1} +2C_{2}\)

Then,

\(1 = C_{1} +C_{2}\)

\(C_{2} = 1 - C_{1}\)

Recall, \(C_{1} = 1\)

∴ \(C_{2} = 1 - 1 = 0\)

\(C_{2} = 0\)

Hence, the solution becomes

\(y(t) = e^{2 t} cos(2 t)\)

We can reject the null hypothesis and conclude that there is evidence to support the alternative hypothesis that the left foot is longer than the right foot.

A statistical test is required to determine whether the length of the left foot is greater than the length of the right foot. The null hypothesis states that there is no difference in average length between the left and right feet. The alternative hypothesis is that the left foot's average length is greater than the right foot's average length.

This hypothesis is one-tailed, as we are only interested in whether the left foot is longer than the right foot. We are not considering the possibility that the right foot could be longer than the left foot.

A t-test can be used to determine whether the difference in average length between the left and right feet is statistically significant. We can reject the null hypothesis and conclude that there is evidence to support the alternative hypothesis that the left foot is longer than the right foot if the p-value of the t-test is less than the chosen significance level (e.g., 0.05).

Answer:

the total number of students on the honor roll increased by 13.8%.

Step-by-step explanation:

Last year, there were a total of 50 + 80 = 130 students on the honor roll.

This year, the number of boys on the honor roll increased by 20%, which means there are now 1.2 * 50 = 60 boys on the honor roll.

The number of girls on the honor roll increased by 10%, which means there are now 1.1 * 80 = 88 girls on the honor roll.

The total number of students on the honor roll this year is 60 + 88 = 148.

The percentage increase in the total number of students on the honor roll is (148-130)/130 * 100% = 13.8%.

Rounding to the nearest tenth, we get that the total number of students on the honor roll increased by 13.8%.

Answer:

29 degrees

Step-by-step explanation:

Note how both triangles are isosceles triangles, which mean two angles will be equivalent. In the triangle with the marked angle measurement, since the total of angles in a triangle is 180, then the measurement of the unmarked angles have a sum of 180-64, which is 116. Then, as stated before, this triangle is isosceles, so the measurement of each unmarked angle is 116/2, which is 58.
Next, notice how the angle below angle x in that triangle shares a line with one of the 58 degree angles. This means that angle is 180-58, which is 122. Now, since the total of angles in a triangle is 180 and the triangle is isosceles, then angle x is (180-122)/2, which is 58/2, or 29 degrees

As a result, about 85.18% of the students in the survey do not smoke, and the probability of not smoking is 0.8518.

Percentages are just fractions with a denominator of 100. We use the percent sign (%) beside a number to indicate that it is a percentage. For instance, if you answered 75 questions correctly out of 100 on a test (75/100), you would have received a 75%. A percentage is a figure or ratio that may be stated as a fraction of 100 in mathematics. If we need to compute the percentage of a number, divide it by the entire and multiply by 100. As a result, the percentage denotes a part per hundred. The term % refers to one hundred percent. The sign "%" represents it.

Here,

The survey included 55 students who smoke and 337 students who do not smoke. The percentage of students who do not smoke can be calculated as follows:

337/(55+337) = 337/392 = 85.18%

So, approximately 85.18% of the students in the survey do not smoke and the probability of student of who don't smoke is 0.8518.

Step-by-step explanation:

Answer:

y = 5/4x - 6

Step-by-step explanation:

First, put 4x + 5y= -45​ in y = mx + b form

4x + 5y= -45​

5y = -4x - 45

y = -4/5x - 9

So, the slope is -4/5. Perpendicular lines have a opposite reciprocal slope, so the line's slope will be 5/4

To find the equation of the perpendicular line, plug in the slope and given point into y = mx + b, and solve for b

y = mx + b

-11 = 5/4(-4) + b

-11 = -5 + b

-6 = b

Plug in b and the slope into y = mx + b

y = 5/4x - 6

So, the equation is y = 5/4x - 6

Step-by-step explanation:

The "enclosed area" can be taken to mean different things. Here, we consider it to mean the finite area bounded between the two curves, regardless of which curve is higher value than the other.

The area is bounded on the interval [0, 2]. On half that interval y1 > y2; on the other half, y2 > y1. This means the integral of the area between the curves will be different for one part of the interval than for the other. (The curves are symmetric about the point (1, 0).)

The area on the interval [0, 1] is given by the integral ...

  \(\displaystyle\int_0^1{(y_1-y_2)}\,dx=\int_0^1{((x-1)^3-(x-1))}\,dx\\\\=\int^1_0{(x(x-1)(x -2))}\,dx=\left.(\frac{x^4}{4}-x^3+x^2)\right|^1_0=\boxed{\frac{1}{4}}\)

The area on the interval [1, 2] is the integral of the opposite integrand, but has the same value.

The positive area over the whole interval from 0 to 2 is 1/4+1/4 = 1/2.

If you simply integrate y2-y1 or y1-y2 over that interval, the result is 0.
