My logical answer is repeat the first survey with different 25 different students

Step-by-step explanation:

The indicates 9 of 25 students surveyed chose her. To determine if her calculation is accurate she needs more survey(s).

How many surveys or the size of sample group could matter.  If she surveys 3 more people, that would not be very accurate.

If she surveys 100 student that would give a better idea of how many students  would vote for her, so I THINK she should repeat the first survey with the same number in the sample size, 25.

Answer: \(g(-2)=2a\)

Step-by-step explanation:

\((f \cdot g)(-2)=f(-2)g(-2)\\\\\therefore a \cdot g(-2)=2a^2 \implies g(-2)=2a\)

The function g(-2) from the given functions is 2a.

Functions are the fundamental part of the calculus in mathematics. The functions are the special types of relations. A function in math is visualized as a rule, which gives a unique output for every input x.

The given functions are f(-2)=a and (f·g)(-2)=2a².

Here, (f·g)(-2)=2a²

f(-2)·g(-2)=2a²

a·g(-2)=2a²

g(-2)=2a²/a

g(-2)=2a

Therefore, the function g(-2) is 2a.

The conjecture we can make about the intersections of planes is; If two planes intersect, it means that they can't intersect at more than one line.

We are told that two parallel planes Q and R are intersected by Plane X. Now, Intersecting planes are planes that are not parallel, and they always intersect in a line. The two planes cannot therefore intersect at more than one line.

Answer:

The gambler's fallacy, also known as the Monte Carlo fallacy or the fallacy of the maturity of chances, is the erroneous belief that if a particular event occurs more frequently than normal during the past it is less likely to happen in the future (or vice versa), when it has otherwise been established that the probability of such events does not depend on what has happened in the past. Such events, having the quality of historical independence, are referred to as statistically independent. The fallacy is commonly associated with gambling, where it may be believed, for example, that the next dice roll is more than usually likely to be six because there have recently been fewer than the usual number of sixes.

The term "Monte Carlo fallacy" originates from the best known example of the phenomenon, which occurred in the Monte Carlo Casino in 1913.[1]

Answer:

7x-y=-30

Step-by-step explanation:

The slope of any parallel equation has to have the same slope, so our equation will be in the format of y=7x+b

No you have to use this to solve for b

2 = -4*7+b

2=-28+b

30 = b

So our equation would be y = 7x+30

Now to convert into standard form we would have to put it intto the format of Ax + By = C

so -7x+y = 30

7x - y = -30

The length of a pendulum that makes one full swing in 1.9 seconds is 3 feet.

As per the given data, the given formula is:

\($T=2 \pi \sqrt{\left(\frac{L}{32}\right)}\) gives the time it takes in seconds.

Where,

T is the time it takes for a pendulum to make one full swing back and forth (in seconds).

L is the length of the pendulum, in feet.

Here we need to find the length of a pendulum that makes one full swing in 1.9 seconds to the nearest foot.

Substitute the given parameters into the formula will give;

\($1.9=2 \pi \sqrt{\left(\frac{L}{32}\right)}\)

Now divide both sides by 2π.

\($ \frac{1.9}{2 \pi}=\sqrt{\left(\frac{L}{32}\right)} \\\)

\($ 0.3024=\sqrt{\left(\frac{L}{32}\right)}\)

Then taking square on both sides.

\($ (0.3024)^2=\frac{L}{32} \\\)

0.09144576 = \($\frac{L}{32}\)

Later multiply both sides by 32.

2.9262 = L

The approximate value of the length of a pendulum:

L ≈ 3

Therefore, the length of a pendulum is about 3 feet.

The temperature at the bottom of the mountain is 50.9 °C.

Let's work through the given information step by step to find the temperature at the bottom of the mountain.

The temperature in the hotel is 21 °C.

The temperature in the hotel is 26.7 °C warmer than at the top of the mountain.

Let's denote the temperature at the top of the mountain as T_top.

So, the temperature in the hotel can be expressed as T_top + 26.7 °C.

The temperature at the top of the mountain is 3.2 °C colder than at the bottom of the mountain.

Let's denote the temperature at the bottom of the mountain as T_bottom.

So, the temperature at the top of the mountain can be expressed as T_bottom - 3.2 °C.

Now, let's combine the information we have:

T_top + 26.7 °C = T_bottom - 3.2 °C

To find the temperature at the bottom of the mountain (T_bottom), we need to isolate it on one side of the equation. Let's do the calculations:

T_bottom = T_top + 26.7 °C + 3.2 °C

T_bottom = T_top + 29.9 °C

Since we know that the temperature in the hotel is 21 °C, we can substitute T_top with 21 °C:

T_bottom = 21 °C + 29.9 °C

T_bottom = 50.9 °C

Therefore, the temperature at the bottom of the mountain is 50.9 °C.

Answer:

D) A search warrant

Step-by-step explanation:

A search warrant is required before the search and collection of evidence to ensure legal authorization and protection of individuals' rights against unreasonable searches and seizures.

Option B, "A crime", is incorrect because the presence of a crime is not a prerequisite for conducting a search and collection of evidence. There are various situations where searches and evidence collection may occur without a crime being involved, such as regulatory inspections, consented searches, or investigations into potential threats or risks.

By your logic when you say law enforcement can conduct a search without a search warrant if there is consent by the owner, that would mean option A would be right, but of course, it's not.

The number of terms of the Maclaurin series for eˣ that should be used to estimate \(e^{0.1}\) to within 0.00001 is 4.

Taylor’s inequality:

If Rn( x ) = 0

Rn(x)=0

Rn​(x)=0.

The given function is eˣ

Thus, all the derivatives of eˣ is eˣ itself.

Suppose that, the nth derivative of eˣ is eˣ

To estimate the value of \(e^{0.1}\) substitute the value of x as 0.1.

Note that Taylor series is called Maclaurin series when a=0.

Usually, Maclaurin series will starts with n=2.

Increase the value of n until the reminder is less than 0.00001.

By Taylor’s inequality,

If | \(f^{n}\)(0.1) | = \(e^{0.1}\)≤ M then | Rₙ(x) |≤\(\frac{M}{(n+1)!}\) \(|0.1-0|^{n+1}\)

Substitute the value of n as 2. Then,

\(|R2(x)|\)≤\(\frac{M}{(2+1)!} |0.1-0|^{2+1}\)

≤ \(\frac{e^{0.1}}{3!} |0.1|^{3}\)

≤ \(\frac{e^{0.1}}{6} 0.001\)

≤ 0.00018

Since \(|R2(x)|\) ≥ choose the value of n as 3. Then,

\(|R3(x)|\) ≤\(\frac{M}{(3+1)!} |0.1-0|^{3+1}\)

≤ \(\frac{e^{0.1}}{4!} |0.1|^{4}\)

≤ \(\frac{e^{0.1}}{24} 0.0001\)

≤ 0.0000046

Therefore, \(|R3(x)|\) ≤ 0.00001

That is, n=3 satisfies the inequality.

So, by adding the 4 terms (when n=0,1,2,and 3) of the Maclaurin series, it

is possible to estimate the value of \(e^{0.1}\) to within 0.00001.

Thus, the number of terms of the Maclaurin series for eˣ that should be used to estimate \(e^{0.1}\) to within 0.00001 is 4.

The number of terms of the Maclaurin series for eˣ that should be used to estimate \(e^{0.1}\) to within 0.00001 is 4.
