Answer:

Step-by-step explanation:

the population will reach 1500 after about 30.1 days.

We can solve for the time t by setting P = 1500 and solving for t:

1500 = 700[tex]e^{(0.03t)}[/tex]

Divide both sides by 700:

2.14 = [tex]e^{(0.03t)}[/tex]

Take the natural logarithm of both sides:

ln(2.14) = ln([tex]e^{(0.03t)}[/tex])

Using the logarithm property that ln([tex]e^{x}[/tex]) = x, we can simplify to:

ln(2.14) = 0.03t

Divide both sides by 0.03:

t = ln(2.14)/0.03

Using a calculator, we get:

t ≈ 30.1 days

Therefore, the population will reach 1500 after about 30.1 days.

The probability that both a male student and a female student from the college are smokers is 0.01 or 1%.

We have,

Let's first find the probability of selecting a male smoker and then the probability of selecting a female smoker.

P(Male smoker) = Number of male smokers / Total number of male students

P(Male smoker) = 29 / (29 + 262)

P(Male smoker) = 0.10

Similarly, the probability of selecting a female smoker is:

P(Female smoker) = Number of female smokers / Total number of female students

P(Female smoker) = 40 / (40 + 360)

P(Female smoker) = 0.10

Now, we can find the probability of selecting both a male smoker and a female smoker by multiplying the probabilities:

P(Both smokers) = P(Male smoker) x P(Female smoker)

P(Both smokers) = 0.10 x 0.10

P(Both smokers) = 0.01

Therefore,

The probability that both a male student and a female student from the college are smokers is 0.01 or 1%.

The statement on theoretical probabilities is True.

Theoretical probabilities, referred to as classical probabilities, are utilized when we can suppose that each conceivable result has an equal chance of happening.

Typically, this is observed in games of luck like tossing a coin or rolling dice, where the chances of every possible outcome are equivalent. Such scenarios permit one to use probability principles and determine the probability of each outcome transpiring.

For instance, with fair coins, it's reasonable to assert that there's an even likelihood for heads or tails, setting both probabilities at 1/2.

Step-by-step explanation:17.023413

The probability that the winner will pull out at least one $100 bill is 7/36, or 19.4%.

The probability of an event occurring is determined by the number of favorable outcomes divided by the total number of possible outcomes.

In this problem, the favorable outcome is that the winner will pull out at least one $100 bill, while the total number of possible outcomes is the number of ways to select 4 bills from the hat, which is 36.

Thus, the probability of the winner pulling out at least one $100 bill is calculated by dividing the favorable outcome by the total number of possible outcomes.

Since there are 7 $100 bills in the hat, the favorable outcome is 7. The total number of possible outcomes is 36, which is calculated by using the formula nCr, where n is the total number of objects and r is the number of objects selected.

In this case, n = 36 and r = 4, so the equation is 36C4.

Thus, the probability that the winner will pull out at least one $100 bill is 7/36, or 19.4%.

The frequency of the wave is 2.62 Hz

Answer:

Step-by-step explanation:

We can start by solving the second equation for y:

1/2y - x = 1

1/2y = x + 1

y = 2x + 2

Now we can substitute this expression for y into the first equation:

y = 2 - 6x

2x + 2 = 2 - 6x

Adding 6x to both sides, we get:

8x + 2 = 2

Subtracting 2 from both sides, we get:

8x = -0

Dividing both sides by 8, we get:

x = 0

Now we can use this value of x to find y:

y = 2x + 2

y = 2(0) + 2

y = 2

Therefore, the solution to the system of equations is x=0 and y=2.

The height of box for the given cuboid satisfied the relation through which the volume of cuboid is satisfied is,  height = x+2

What about volume of cuboid?

A cuboid is a three-dimensional shape that has six rectangular faces, where each face has four sides and four right  angles. The volume of a cuboid is the amount of space that it occupies in three-dimensional space. It is measured in cubic units.

The formula to calculate the volume of a cuboid is given by multiplying its length, width, and height.

Volume of cuboid = Length x Width x Height

The volume of a cuboid can be used to determine the amount of space that it can hold or the amount of material required to fill it.

The volume of a cuboid can be calculated by multiplying its length, width, and height.

If the length of the cuboid is represented by "l", the width by "w", and the height by "h", then the volume can be calculated using the formula:

Volume of cuboid = l x w x h

According to the given information:

As, we know that the volume of cuboid = length x breath x height

Given volume of cuboid is = [tex]x^{3} + 6x^{2} +11x^{} + 6[/tex]

And width = x + 1 and length = x + 3.

Volume of cuboid = length x breath x height

⇒ [tex]x^{3} + 6x^{2} +11x^{} + 6[/tex] = (x + 1)(x + 3) x height

⇒ height = [tex]\frac{x^{3} + 6x^{2} +11x^{} + 6}{(x+1)(x+3)}[/tex]

⇒ height = [tex]\frac{(x+1)(x+2)(x+3)}{(x+1)(x+3)}[/tex]

⇒ height = (x+2)

So, the height of the given cuboid is (x+2)

The correlation coefficient between the minutes the actor appeared shirtless in a film and the film's opening weekend gross is 0.75.

In this scenario, the minutes shirtless (x) would be plotted on the x-axis of the scatter plot while the open weekend gross (y) would be plotted on the x-axis of the scatter plot.

By critically observing the scatter plot (see attachment) which models the relationship between the minutes shirtless (x) and the open weekend gross (y), an equation for the linear regression is given by:

y = 10.83 + 0.86x

Correlation coefficient, r = 0.7488571925 ≈ 0.75

The measure of ∠LPN is 57°.

An arc is a segment of a circle in geometry that is typically defined by two endpoints and the arc itself, which is the collection of all points on the circle that are situated between the two endpoints.

The subtendency of an arc can be measured by measuring its central angle.

Since angles inscribed in the same arc are congruent, we have:

m(arc LP) = m(arc NP) = 102° + 144° = 246°

Now, using the fact that the sum of the measures of the arcs of a circle is 360°, we have:

m(arc LM) + m(arc LP) + m(arc NP) + m(arc MN) = 360°

Substituting the known values, we get:

m(arc LM) + 246° + m(arc MN) = 360°

Simplifying, we have:

m(arc LM) + m(arc MN) = 114°

But angles inscribed in the same arc are congruent, so we have:

m(∠LPN) = (m(arc LM) + m(arc MN))/2

Substituting the value we found for m(arc LM) + m(arc MN), we get:

m(∠LPN) = 114°/2 = 57°
