Step-by-step explanation:

a) Probability that Box #1 is empty is computed here as:

= Number of ways to distribute each of the the n balls in remaining (n - 1) boxes / Total ways to distribute n balls into n boxes

= [tex]\frac{(n-1)^n}{n^n} = (1 - \frac{1}{n})^n[/tex]

This is the required probability here.

b) Probability that only 1 box is empty is computed here as:

= Number of ways to choose one of the remaining (n - 1) boxes such that it will have 2 balls * Number of ways to select 2 balls of that box* permutation of remaining (n - 2) balls into (n - 2) boxes / Total ways to distribute n balls into n boxes

= [tex]\frac{\binom{n-1}{1}\binom{n}{2}(n-2)!}{n^n}[/tex]

= [tex]\frac{(n-1)n!(n-2)!}{2n^n}[/tex]

= [tex]\frac{n!(n-1)!}{2n^n}[/tex]

This is the required probability here.

c) Probability that only 1 box is empty is computed here as:

= Number of ways to select a box which would be empty * Probability that only that box would be empty ( from previous part)

= [tex]\frac{n*n!(n-1)!}{2n^n}[/tex]

= [tex]\frac{(n!)^2}{2n^n}[/tex]

This is the required probability here.

d) Given that box #1 is empty, probability that only 1 box is empty is computed here as:

= Probability that only box 1 is empty / Probability that box 1 is empty

We will use the answers from parts a) and b) here to get:

=[tex]\frac{ \frac{n!(n-1)!}{2n^n}}{\frac{(1 - n)^n}{n^n}}[/tex]

= [tex]\frac{n!(n-1)!}{2(1-n)^n}[/tex]

This is the required probability here.

e) Given that only 1 box is empty, probability that box #1 is empty is computed here as:

= 1/n as each box is equally likelt to be empty

Therefore 1/n is the required probability here.

Adding the negative value in front of x flips the graph lacrosse the Y axis and compressed it vertically.

The answer is C.

Answer:

C. The graph of G(x) is the graph of F(x) flipped over the y-axis and compressed vertically.

Step-by-step explanation:

The negative in front of the 2 made the function flip over the y-axis. While the 2, compressed the function a little, making it so the function touched 2, vertically.

Answer:

Step-by-step explanation:

Given

height of the pine cone above the ground can be modelled by

[tex]h=-16t^2+40[/tex]

When pine cone reaches the ground [tex]h=0[/tex]

[tex]\Rightarrow 0=-16t^2+40[/tex]

[tex]\Rightarrow 40=16t^2[/tex]

[tex]\Rightarrow t=\sqrt{\frac{40}{16}}[/tex]

[tex]\Rightarrow t=\frac{\sqrt{40}}{4}[/tex]

[tex]\Rightarrow t=\frac{2\sqrt{10}}{4}[/tex]

[tex]\Rightarrow t=\frac{\sqrt{10}}{2}[/tex]

[tex]\Rightarrow t=1.58\ s[/tex]

Thus cone take 1.58 s to reach ground

Answer:

13/50; 13/50

Step-by-step explanation:

a): Theoretical=# of favorable outcomes/# of total outcomes

To find the total, add 21+26+25+28, which is 100

A has a frequency of 26.

That would be 26/100, which is also 13/50

b): Experimental probability is based on the amount of times the spinner is spun. Since A is the only vowel in "MATH", we would take that fraction and multiply it by 100, or the number of times.

13/50*100=13*2=26

Put that over 100, which would be 26/100, which is also 13/50.

Hope this helped! Have a good rest of your day!

Answer:

The number of students who attend music club only is 13.

Step-by-step explanation:

The three different types of clubs are:

D = drama club

M = music club

S = sports club

The information provided is:

n (M) = 39

n (D) = 35

n (Exactly 2 clubs) = 26

Consider the Venn diagram attached.

From the Venn diagram it is clear that 13 students attended the Music club only.

Thus, the number of students who attend music club only is 13.

Answer:

100

Step-by-step explanation:

At the start, the tank contains

(0.25 lb/gal) * (100 gal) = 25 lb

of sugar. Let [tex]S(t)[/tex] be the amount of sugar in the tank at time [tex]t[/tex]. Then [tex]S(0)=25[/tex].

Sugar is added to the tank at a rate of P lb/min, and removed at a rate of

[tex]\left(1\frac{\rm gal}{\rm min}\right)\left(\dfrac{S(t)}{100}\dfrac{\rm lb}{\rm gal}\right)=\dfrac{S(t)}{100}\dfrac{\rm lb}{\rm min}[/tex]

and so the amount of sugar in the tank changes at a net rate according to the separable differential equation,

[tex]\dfrac{\mathrm dS}{\mathrm dt}=P-\dfrac S{100}[/tex]

Separate variables, integrate, and solve for S.

[tex]\dfrac{\mathrm dS}{P-\frac S{100}}=\mathrm dt[/tex]

[tex]\displaystyle\int\dfrac{\mathrm dS}{P-\frac S{100}}=\int\mathrm dt[/tex]

[tex]-100\ln\left|P-\dfrac S{100}\right|=t+C[/tex]

[tex]\ln\left|P-\dfrac S{100}\right|=-100t-100C=C-100t[/tex]

[tex]P-\dfrac S{100}=e^{C-100t}=e^Ce^{-100t}=Ce^{-100t}[/tex]

[tex]\dfrac S{100}=P-Ce^{-100t}[/tex]

[tex]S(t)=100P-100Ce^{-100t}=100P-Ce^{-100t}[/tex]

Use the initial value to solve for C :

[tex]S(0)=25\implies 25=100P-C\implies C=100P-25[/tex]

[tex]\implies S(t)=100P-(100P-25)e^{-100t}[/tex]

The solution is being drained at a constant rate of 1 gal/min; there will be 5 gal of solution remaining after time

[tex]1000\,\mathrm{gal}+\left(-1\dfrac{\rm gal}{\rm min}\right)t=5\,\mathrm{gal}\implies t=995\,\mathrm{min}[/tex]

has passed. At this time, we want the tank to contain

(0.5 lb/gal) * (5 gal) = 2.5 lb

of sugar, so we pick P such that

[tex]S(995)=100P-(100P-25)e^{-99,500}=2.5\implies\boxed{P\approx0.025}[/tex]

Answer:

520

Step-by-step explanation:

80 times 6.5 = 520

so she can type 520 words in 6.5 mins

Answer:

The answer would be 520

Step-by-step explanation:

We have 80 words per minutes:)

It asks how much words can we type in 6.5 minutes.

well if we do 80 words per minute we can multiply the values

80 words x 6 minutes is 480

But wait we have .5 left

so we do 80 divided by 2 and get 40

then we go 480 plus 40 and get 520

we could have straight out multiplyed it and got this but thats no fun.

520 Words for 6.5 mins :)

Answer:

Center = (5, 0)

Radius = 9

Step-by-step explanation:

Look at the picture

The radius of the circle is 9units and the center of the circle is at (5, 0)

The standard equation of a circle is expressed as:

(x-a)^2+(y-b)^2 = r^2

where

r is the radius of the circle

(a, b) is the centre of the circle

GIven the equation is (x – 5)² + y² = 81.

Compare both equations

a = 5, b = 0

r^2 = 81

r = 9units

Hence the radius of the circle is 9units and the center of the circle is at (5, 0)

Answer:

Garret placed the treasure at the right place.

Step-by-step explanation:

The Cartesian plane can be used to locate the position of any given point with a coordinate. It consists of two numbered lines perpendicular to each other and intersecting at point zero of the lines.

From the statements given, 5 units from x-axis is not the same as 5 units on x-axis. Also, 3 units from y-axis is not the same as 3 units on y-axis.

So, distance 5 units from x-axis implies that a point 5 units after the x-axis. And also, distance 3 units from y-axis means 3 units after the y-axis.

With these conditions of the coordinate of the treasure, Garrett placed the treasure at the right place.

Hey there! I'm happy to help you out!

Let's think of our original price ($P) as 100%. This is also the same thing as 1 because 100% is one whole thing.

Now, we see that he got a 15% off discount. Now, we just subtract 15% from 100% to see what percent he actually payed.

100%-15%=85%

This means that $R is 85% of $P (100%).

Answer A is not correct because 0.85% is less than 1%, which is not 85%.

Answer B is not correct either because 0.15% is also less than 1%.

Answer C is correct because $R is 85% of the original cost.

Answer:

The value of the intercept is a=216.

Step-by-step explanation:

We define "s" as the number of scarecrows and "C" the number of crops eaten.

The farmer finds the linear regression equation:

[tex]C=a-0.8s[/tex]

We have a linear function, for which we only know the slope (m=0.8) and a point within it (when s=20, C=200).

We can find a replacing the variables C asn s with the known point (20, 200):

[tex]C=a-0.8s\\\\C(20)=a-0.8(20)=200\\\\a=200+0.8*20=200+16\\\\a=216[/tex]

The value of the intercept is a=216.
