Step-by-step explanation:

Answer:

I believe the answer is A

Step-by-step explanation:

I say it's A because the volume is double like it told us. Compared to the new box it's twice as long as the old boxes.

I hope this helps! ~~~~

The volume of the new box is 8 times the volume of the old box.

The correct answer is option (D).

The volume of a rectangular box with length L, width W and height H is,

V = L × W × H

Given: -

Let [tex]l,w,h[/tex] represents the length, width and height of the old rectangular boxes.

Let [tex]V_o[/tex] represents the volume of the old rectangular box.

⇒ [tex]V_o=l\times w \times h[/tex]

The length, width and height of the new boxes are all twice as long as those of the old boxes.

This means the length, width and height of the new boxes would be [tex]2l,2w,2h[/tex].

Let [tex]V_n[/tex] represents the volume of the new rectangular box.

So, the volume of the new rectangular box would be,

⇒ [tex]V_n=2l \times 2w \times 2h[/tex]

⇒ [tex]V_n = 8 \times l \times w \times h[/tex]

⇒ [tex]V_n=8 \times V_o[/tex]

This means, the volume of the new box is 8 times the volume of the old box.

Hence, option (D) is the correct answer.

Answer:

1278.04

Step-by-step explanation:

Why? In 1 year there are approximately 365.24 days, but in 1 month there are approx 30.42 days.

So 365.24 × 2 =                   730.48

And 30.42 × 18 =                 547.56   (+

                                    -----------------------

                                           1278.04

Given:

The function is

[tex]r(x)=0.05(x^2+1)(x-6)[/tex]

where, function r gives the instantaneous growth rate of a fruit fly population x days after the start of an experiment.

To find:

Number of complex and real zeros.

Time intervals for which the population increased and population deceased.

Solution:

We have,

[tex]r(x)=0.05(x^2+1)(x-6)[/tex]

[tex]r(x)=0.05(x^3+x-6x^2-6)[/tex]

Here, degree of function x is 3. It means, the given function has 3 zeros.

From the given graph it is clear that, the graph of function r(x) intersect x-axis at once.

So, the given function r(x) has only one real root and other two real roots are complex.

Therefore, function r has 2 complex zeros and one real zero.

Before x=6, the graph of r(x) is below the x-axis and after that the graph of r(x) is above the x-axis.

Negative values of r(x) represents the decrease in population and positive value of r(x) represents the increase in population.

Therefore, based on instantaneous growth rate, the population decreased between 0 and 6 hours and the population increased after 6 hours.

Answer:

Function r has two complex zeros and one real zero. Based on the instantaneous growth rate, the population decreased between 0 and 6 hours and the population increased after 6 hours.

Answer:

18 Nickels, 6 Quarters

Step-by-step explanation:

For this problem, let's build a system of equations to find the number of nickels and dimes you have.  Let N represent the number of nickels and Q represent the number of quarters you have.

The first equation, you have 3 times as many nickels as quarters:

N = 3Q

The second equation, you have a total of $2.40.  Given we know nickels are $0.05 and quarters are $0.25:

0.05N + 0.25Q = 2.40

Now, let's use the two equations to find the number nickels and quarters you have.

N = 3Q

0.05N + 0.25Q = 2.40

0.05(3Q) + 0.25Q = 2.40

0.15Q + 0.25Q = 2.40

0.4Q = 2.40

Q = 6

Now, let's plug the value back into the equation:

N = 3Q

N = 3(6)

N = 18

And we can verify these values with the second equation:

0.05N + 0.25Q = 2.40

0.05(18) + 0.25(6) ?= 2.40

0.90 + 1.50 ?= 2.40

2.40 == 2.40

Therefore, we have found and verified the amount of Nickels and Quarters you have.

Cheers.

Answer:

(a) Explained below.

(b) 0.0294

(c) 0.0173

(d) 0.09827

(e) 0.0452

Step-by-step explanation:

The complete question is:

According to an​ airline, flights on a certain route are on time 80​% of the time. Suppose 25 flights are randomly selected and the number of​ on-time flights is recorded.

​(a) Explain why this is a binomial experiment.

​(b) Find and interpret the probability that exactly 16 flights are on time. ​

(c) Find and interpret the probability that fewer than 16 flights are on time.

​(d) Find and interpret the probability that at least 16 flights are on time.

​(e) Find and interpret the probability that between 14 and ​16 flights, inclusive, are on time.

Solution:

(a)

Let the random variable X be defined as the number of​ on-time flights.

A Binomial experiment has the following properties:

If a random variable X is used in an experiment and the experiment has all the above mentioned properties, then the random variable X is known as a binomial random variable.

All of these properties can be confirmed for the random variable X.

Thus, this is a binomial experiment.

(b)

Compute the probability that exactly 16 flights are on time as follows:

[tex]P(X=16)={25\choose 16}(0.80)^{16}(0.20)^{25-16}[/tex]

        [tex]=2042975\times 0.0281475\times 0.000000512\\=0.029442375072\\\approx 0.0294[/tex]

Thus, the probability that exactly 16 flights are on time is 0.0294.

(c)

Compute the probability that fewer than 16 flights are on time as follows:

[tex]P(X<16)=\sum\limits^{15}_{x=0}{{25\choose x}(0.80)^{x}(0.20)^{25-x}}[/tex]

                 [tex]=0.0000+0.0000+....+0.011777\\=0.0173[/tex]

Thus, the probability that fewer than 16 flights are on time is 0.0173.

(d)

Compute the probability that at least 16 flights are on time as follows:

[tex]P(X\geq 16)=1-P(X<16)[/tex]

                 [tex]=1-0.0173\\=0.9827[/tex]

(e)

Compute the probability that between 14 and 16 ​flights, inclusive, are on time as follows:

[tex]P(14\leq X\leq 16)=\sum\limits^{16}_{x=14}{{25\choose x}(0.80)^{x}(0.20)^{25-x}}[/tex]

                          [tex]=0.004+0.0118+0.0294\\=0.0452[/tex]

Thus, the probability that between 14 and 16 ​flights, inclusive, are on time is 0.0452.
