Answer:

Line segments A'B' and C'D' do not intersect and are the same distance apart as AB and CD.

Step-by-step explanation:

For fixed population standard deviation and level of significance, the minimum sample size needed to guarantee a given margin of error decreases as the margin of error increases.

The square root of the variance for the given set of numbers is what the standard deviation examines. It is employed to compute a confidence interval for making judgments (such as accepting or rejecting a hypothesis).

Here, the population standard deviation, and level of significance are the same.

As the margin of error increased.

So, with the increase in the value of the margin of error, there will surely decrease in the value of the sample size

\($$\begin{aligned}&\mathrm{MOE}_\gamma=z_\gamma \times \sqrt{\frac{\sigma^2}{n}}\\&\begin{aligned}\mathrm{MOE} & =\text { margin of error } \\\gamma & =\text { confidence level } \\z_\gamma & =\text { quantile } \\\sigma & =\text { standard deviation } \\n & =\text { sample size }\end{aligned}\end{aligned}$$\)

As the margin of error is in the denominator position in the sample size formula

Hence with an increase in the margin of error sample size decreases.

Step-by-step explanation:

Use some dimensional analysis. There are 60 minutes in 1 hour, and 60 seconds in 1 minute:

\( \frac{23}{1} \frac{units}{hour} \times \frac{1}{60} \frac{hour}{minutes} \times \frac{1}{60} \frac{minute}{seconds} \)

The units of hour will cancel, minutes will cancel, leaving the units of seconds:

The inequality you use to solve the question is 36 + 4x < 95.

We have given that,

Rahul pay a flat cost of $36 per month, rate is $4 per gigabyte and rahul want to keep his bill under $95 per month

we have to find inequality.

We know that total charge per month is,

C(x) = Flat cost + rate per gigabyte × number of gigabyte

let the number of gigabyte be x

putting the values we get,

C(x) = 36 + 4x

and Rahul want to keep his bill under $95 per month.

Therefore

36 + 4x < 95

⇒      4x > 59

          x < 14.75

Hence the inequality you use to solve the answer is 36 + 4x < 95.

The object fell from a height of approximately 7.057 meters above the ground.


We can solve this problem using the equations of motion for a freely falling object. The equation we’ll use is:
H = (1/2) * g * t^2
Where h is the initial height, g is the acceleration due to gravity (approximately 9.8 m/s^2), and t is the time taken to travel the last distance. Rearranging the equation, we get:

H = (24.0 m) + (1/2) * (9.8 m/s^2) * (1.20 s)^2
Calculating this expression, we find that h is approximately 7.057 meters. Therefore, the object fell from a height of approximately 7.057 meters above the ground.

Step-by-step explanation:

The concept of independent assortment is one of the fundamental principles of genetics that was first proposed by Gregor Mendel. According to Mendel's postulate of independent assortment, the alleles of different genes segregate independently of one another during the formation of gametes. This means that the inheritance of one trait does not affect the inheritance of another trait.

To test this postulate, Mendel conducted numerous experiments on pea plants and observed that the inheritance of different traits followed a predictable 1:2:1 ratio. This ratio indicated that the alleles for each trait were segregating independently of each other.

Overall, the content loaded Mendel's postulate of independent assortment is an important concept in genetics that helps explain how genetic variation is generated. The 1:1:1:1 testcross ratio is one of the many ways in which this postulate can be tested and supported.

Answer:

The distance of  Musah's final point from the center in the west direction is   60.355 steps

The distance of  Musah's final point from the center in the north direction is   85.355 steps

Step-by-step explanation:

Given that :

Musah stands at the center of a rectangular field.

He takes 50 steps north, then 25 steps West and finally 50 on a bearing of 315°.

The sketch for Musah's movement is seen in the attached file below.

How far west is Musah's final point from the centre?

In order to determine how far west  is Musah's,

Let d be the distance of how far west;

Then d = BC + CD cos θ

In the North West direction,

cos θ = cos 45°

d = 25 + 50( cos 45°)

d = 25 + 50(\(\dfrac{1}{\sqrt{2}}\)  )

d = 25 + 50( 0.7071)

d =25 + 35.355

d = 60.355 steps

How far north is Musah's final point from the center?

Let d₁ be the distance of how far North;

Then d₁ = AB + CD sin  θ

d₁ = 50 + 50  sin  45°

d₁ = 50 + 50(\(\dfrac{1}{\sqrt{2}}\)  )

d₁ = 50 + 50( 0.7071)

d₁ = 50 + 35.355

d₁ = 85.355  steps

The probability that both people own a dog is 0.01 (or 0.0100 when rounded to four decimal places).

Here we assume that the we have the condition of independence of the probability on any other event, so, by multiplying the probabilities we can get out answer. The likelihood of having a dog is 10% (0.10) for each individual chosen at random, thus when we combine these probabilities together so that we get the probabilities of the two events combined with each other in this case,

0.10(0.10) = 0.01

The correct option for the evaluated integral 14∫x³√(x² + 8) dx is d. 14/3 (x² + 8) ³/2 - 112(x² + 8) ¹/² + c.

To evaluate the given integral, we can use the substitution method. Let u = x² + 8. Taking the derivative of u with respect to x gives du/dx = 2x, and solving for dx, we have dx = du/(2x).

Substituting the values into the integral, we get:

14∫x³√(x² + 8) dx = 14∫(x * √(x² + 8)) dx

= 14∫(x * √u) (du/(2x))

= 7∫√u du.

Integrating √u with respect to u, we obtain:

7∫√u du = 7 * (2/3)u^(3/2) + c

= 14/3 u^(3/2) + c

= 14/3 (x² + 8)^(3/2) + c.

Therefore, the correct option is d. 14/3 (x² + 8) ³/2 - 112(x² + 8) ¹/² + c.

Answer: The statement "No U.S. president has been younger than 65 at the time of his inauguration" is false. A counterexample can be found in the table provided:

John F. Kennedy was 43 years old at the time of his inauguration, which is younger than 65. Therefore, John F. Kennedy serves as a counterexample that disproves the given statement.

Step-by-step explanation:

The statement claiming no U.S. president has been younger than 65 at the time of inauguration is false. Theodore Roosevelt, John F. Kennedy, and Barack Obama were all inaugurated while younger than 65, with Roosevelt being the youngest inaugural president at 42.

The statement 'No U.S. president has been younger than 65 at the time of his inauguration' is proven to be false through the use of counterexamples. Theodore Roosevelt, John F. Kennedy, and Barack Obama were all under the age of 65 at the time of their inaugurations. It can therefore be concluded that the original statement is not true. For example, Theodore Roosevelt was only 42 years old when he was inaugurated, making him the youngest U.S. president at the time of inauguration.

cos y = adjacent / hypotenuse

substituting adjacent = 5, hypotenuse = 15

cos y = 5/15

cos y = 1/3

y = arc cos (1/3)

y = 70.53°

Therefore, we conclude that:

Gustavo's percent increase in points is 75%.

To calculate the percent increase, we need to find the difference between the new value and the original value, divide that difference by the original value, and then multiply by 100.

Gustavo's original score was 8000 points, and his new score is 14,000 points. The difference between the new score and the original score is 14,000 - 8000 = 6000 points.

To find the percent increase, we divide the difference by the original score: 6000 / 8000 = 0.75.

To express this as a percentage, we multiply by 100: 0.75 * 100 = 75%.

Therefore, Gustavo's percent increase in points is 75%. He has increased his points by 75% from 8000 to 14,000 points.

The area enclosed by the curve x = t^2 − 3t, y = √t and the y-axis is 2.08 square units.

We have been given parametric equations x = t^2 − 3t, y = √t

We need to find the area enclosed by the curve x = t^2 − 3t, y = √t and the y-axis.

Consider x = 0

So, t^2 − 3t =  0

t(t - 3) = 0

t = 0   or  t = 3

Let f(t) =  t^2 − 3t and g(t) = t

Differentiate the curve f(t) with respect to t.

f'(t) = 2t - 3

NWe know that the formula to find the area under the curve.

A = ∫[a to b] g(t)f'(t) dt

here, a = 0 and b = 3

so, A = ∫[0 to 3] √t (2t - 3) dt

A = ∫[0 to 3] (2t√t - 3√t) dt

A = ∫[0 to 3] (2t^(3/2) - 3t^(1/2)) dt

A = [4/5 t^(5/2) - 2 t^(3/2)]_[t = 0, t = 3]

A = 4/5 3^(5/2) - 2 3^(3/2) - 0 + 0

A = 4/5 3^(5/2) - 2 3^(3/2)

A = 6√3 /5

A = 2.08
