Answer:

a = 70°

b = 80°

Step-by-step explanation:

Angles on a straight line add up to 180°

⇒ a + 110 = 180

⇒ a = 180 - 110

⇒ a = 70°

The sum of the interior angles of a quadrilateral is 360°

⇒ a + b + 130 + 80 = 360

⇒ 70 + b + 130 + 80 = 360

⇒ b + 280 = 360

⇒ b = 360 - 280

⇒ b = 80°

Step-by-step explanation:

The correct option e) 94.29%, for the probability that among the next 166 responses there will be at most 43 correct answers.

If we use a normal distribution to simulate any binomial distribution with p = 0.24 for n = 166 results, then:

There should be 43 correct responses, or

μ = np = 166*0.24

μ = np = 34.86

The number of accurate responses has a standard deviation of

σ = √(np(1-p))

σ = √(34.86*0.76)

σ = 5.14

43 correct responses have a z-value;

z = (x - μ)/σ

z = (43 - 34.86)/5.14

z = 1.58

The likelihood that 43 accurate responses are provided is:

N(1.58) = 0.9429

Thus, the probability that among the next 166 responses there will be at most 43 correct answers is 94.29%.

The amount that Mr. and Mrs. Howard should invest to be able to send their son to college in 13 years is $ 2, 650. 93 .

A simple way to find the amount that Mr. and Mrs. Howard need to invest when using continuous compounding is :

Amount needed in future = Amount needed to be invested x Continuously compounded factor, 13 years, 8 %

Amount needed in future = $ 7, 500

Continuously compounded factor, 13 years, 8 % = 2. 8292

The amount to be invested is :

Amount needed in future = Amount needed to be invested x Continuously compounded factor, 13 years, 8 %

7, 500 = Amount x 2. 8292

Amount = 7, 500 / 2. 8292

Solution:

Note that:

First, let's convert the yards into feet.

Now, divide 18 both sides to find the cost of 1 foot.

The price of the twine per foot is $0.16.

The first step is to convert yards to foot: 1 yard = 3 foot

In order to convert yards to foot, multiply 6 by 3: 6 x 3 = 18 foot

The price per foot can be determined by dividing $2.88 by 18 foot

$2.88 / 18 = $0.16

Therefore, In the figure, a∥b  angle m∠7 = 34° .

An angle is a figure in Euclidean geometry made up of two rays that share a vertex, or common terminus, and are referred to as the sides of the angle. Angles of two rays lie in the plane containing the rays. Angles can also result from the intersection of two planes. Dihedral angles are the name given to them.

Here,

Given that a and b are parallel lines,

∠3 and ∠7  are corresponding angles and congruent

The depth to which the straight line would go into the fluid of the large petroleum storage tank is approximately 0.0147ft (or 0.177 inches). This is calculated based on the volume of the spherical segment that corresponds to the tank's diameter.

To determine this depth, we can calculate the segment of the sphere that corresponds to the tank's diameter. The height of this segment represents the depth of the fluid.

Using the formula for the volume of a spherical segment, we find that the volume is proportional to the square of the radius multiplied by the depth. By rearranging the formula, we can solve for the depth:

The volume of the segment = \((\pi/6) \times h \times (3r^2 + h^2)\)

Given the radius of the sphere (4000 mi) and the diameter of the tank (100ft), we convert the measurements to consistent units. The radius becomes 4000*5280ft, and the diameter becomes 100ft.

Substituting these values into the equation, we can solve for the depth. The result is approximately 0.0147ft or 0.177 inches.

The problem entails calculating the probability for a scenario in which the IRS audits 30% of tax returns at random and a married pair has filed separate returns. Calculate the chances of both husband and wife being audited, just one of them being audited, neither of them being audited, and at least one of them being audited.

a) Probability that both the husband and the wife will be audited: (0.3)² = 0.09 or 9%

b) Probability that only one of them will be audited:

c) Probability that neither one of them will be audited: (0.7)² = 0.49 or 49%

d) Probability that at least one of them will be audited: This is the complement of the probability that neither one of them will be audited. So, the probability that at least one of them will be audited is 1 - 0.49 = 0.51 or 51%.

EF = \(\sqrt{34}\) ≈ 5.83

Step-by-step explanation:

Calculate EF using the distance formula

d = \(\sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1})^2 }\)

with (x₁, y₁ ) = E(1, 3) and (x₂, y₂ ) = F(- 2, 8)

EF = \(\sqrt{(-2-1)^2+(8-3)^2}\)

    = \(\sqrt{(-3)^2+5^2}\)

    = \(\sqrt{9+25}\)

    = \(\sqrt{34}\) ≈ 5.83 ( to 2 dec. places )

Let's denote the time it took Juan Pablo to drive from home to college as "t1" and the time it took him to drive back from college to home as "t2". We know that the average speed is equal to the total distance divided by the time taken.

The distance from home to college is the same as the distance from college to home, so we can denote it as "d".  Using the formula: Speed = Distance / Time, we can write the equations: 59.6 = d / t1     (Equation 1) 67.2 = d / t2     (Equation 2) We are also given that the total round trip took 10 hours, so we have the equation: t1 + t2 = 10     (Equation 3) To solve these equations, we can rearrange Equation 1 and Equation 2 to solve for "d" in terms of "t1" and "t2": d = 59.6 * t1     (Equation 4) d = 67.2 * t2     (Equation 5) Now, substituting Equation 4 and Equation 5 into Equation 3, we get: 59.6 * t1 + 67.2 * t2 = 10 Solving this equation will give us the values of t1 and t2. However, we need additional information to find a unique solution for t1 and t2.

The probability of winning at least one award is 1 - 0.2373 = 0.7627 or 76.27%.

If the probability of winning an MTV music award after being nominated is 25%, the probability of not winning is 75%. Thus, the probability of not winning any of the five awards is (0.75)^5 = 0.2373.

As for how many awards Ariana Grande should expect to win, we can use the expected value formula: E(x) = n * p, where n is the number of trials (in this case, 5) and p is the probability of success (0.25). Therefore, E(x) = 5 * 0.25 = 1.25. So, Ariana Grande can expect to win about 1 award.

Finally, to calculate the standard deviation associated with this probability, we can use the formula: σ = sqrt(n * p * (1-p)). Plugging in the values, we get σ = sqrt(5 * 0.25 * 0.75) = 0.866. Therefore, the standard deviation associated with this probability is approximately 0.866.

The Law of Cosines applying here is c^2 = a^2 + b^2 - 2ab*cos C.

Here c = 8 ft, b = 16 ft and a = 17 ft.  Plugging these values into the above equation yields

8^2 = 17^2 + 16^2 - 2(17)(16)cos A, or

64 = 289 + 256 - 544*cos A, or

-481 = -544*cos A

Dividing both sides by -544 yields:   cos A = 0.884

Using the inverse cosine function on a calculator, we get A = Y = 0.486 radians, or 27.8 degrees

The surface area of the prism is 96 cm²

Surface area is the sum of the areas of all the faces (or surfaces) of a three-dimensional object.

The length and width of the rectangular face are 4.5 cm and 3 cm, respectively, so the area is:

4.5 cm x 3 cm = 13.5 cm²

Since there are two rectangular faces on the prism, the total area for the pair is:

= 2 x 13.5 cm²

= 27 cm²

Similarly for the another face

3 cm x 3 cm = 9 cm²

Since there are two square faces on the prism, the total area for the pair is:

= 2 x 9 cm²

= 18 cm²

The area of one of the rectangular faces that is not congruent to the first two:

= 8.5 cm x 3 cm

= 25.5 cm²

Since there are two rectangular faces that are not congruent to the first two, the total area for the pair is:

= 2 x 25.5 cm²

= 51 cm²

Now we can find the total surface area by adding the area of each pair of faces:

= 27 cm² + 18 cm² + 51 cm²

= 96 cm²

Therefore, the surface area of the rectangular prism is 96 square centimeters.

The mean score of 90, and percentile of Bob's score of 80, gives Bob's exam score as approximately 92.5%

The Z-Score of the 80th percentile is 0.8416

The formula for Z-Score is presented as follows;

\(z = \frac{x - \mu}{ \sigma} \)

Where;

\( \sigma = The \: standard \: deviation\)

\( \mu = The \: mean = 90\%\)

x = The given score

Taking the mean as a proportion, we have;

\( \sigma = \sqrt{\frac{\mu \cdot (1-\mu)}{n}}\)

Which gives;

\( \sigma = \sqrt{\frac{0.9 \times (1-0.9)}{100}}= 0.03\)

Therefore, when z = 0.8416, gives;

\(0.8416 = \frac{x - 0.9}{ 0.03} \)
