100 POINTS!!!!!! MAY SOMEONE PLEASE HELP ME!!!! I NEED IT BAD!
THANK YOU IN ADVANCE!

Answer:

[tex]P(X<50)=P(\frac{X-\mu}{\sigma}<\frac{50-\mu}{\sigma})=P(Z<\frac{50-60.5}{7.2})=P(z<-1.46)[/tex]

And we can find the probability using the normal standard distribution or excel and we got:

[tex]P(z<-1.46)=0.0721[/tex]

Step-by-step explanation:

Let X the random variable that represent the shelf life of packed food of a population, and for this case we know the distribution for X is given by:

[tex]X \sim N(60.5,7.2)[/tex]  

Where [tex]\mu=60.5[/tex] and [tex]\sigma=7.2[/tex]

We are interested on this probability

[tex]P(X<50)[/tex]

For this case we can solve this problem with the z score formula:

[tex]z=\frac{x-\mu}{\sigma}[/tex]

If we apply this formula to our probability we got this:

[tex]P(X<50)=P(\frac{X-\mu}{\sigma}<\frac{50-\mu}{\sigma})=P(Z<\frac{50-60.5}{7.2})=P(z<-1.46)[/tex]

And we can find the probability using the normal standard distribution or excel and we got:

[tex]P(z<-1.46)=0.0721[/tex]

Answer:

Yes

Step-by-step explanation:

A function has one input (x-value) per output (y-value).

In other words, a relation that does not repeat any x values is a function.

{(3,4) , (5,0) , (2,4) , (-5,-5)}

The domain of the relation is:

{-5,2,3,5}

Since none of the numbers repeat in the domain, the relation is a function.

Answer:

Step-by-step explanation:

Answer:

14.4 m

Step-by-step explanation:

let the height of the tower from line of sight be x, then

tan23° = [tex]\frac{opposite}{adjacent}[/tex] = [tex]\frac{x}{30}[/tex] ( multiply both sides by 30 )

30 × tan23° = x , thus

x ≈ 12.7 m

Total height of tower = 12.7 + 1.7 = 14.4 m ( to the nearest tenth )

Answer:

It is inverted and shifted down 3 units.

Red is f(x) = x^2

Purple is f(x) = -x^2 -3

Step-by-step explanation:

Answer:

V cone = pi• radius ^2 • height/ 3  

V cylinder= pi• radius ^2. • height  

1) three times cone is smaller then cylinder that have the same radius and height

Answer:

here is how

Step-by-step explanation:

the x (6) is the horixontal ways on the co-ordinate plane. you go right until you reach the six. the y (4) is vertical. take the point that is on 6,0. and move it up until you see it on 4. now you have the coordinates 6,4.

Answer:

(3,1)

Step-by-step explanation:

5x + 3y = 18

2x + 3y = 9

So we can use elimination here to solve this system of equations by multiplying the second equation by -1

Now we have:

5x + 3y = 18

-2x - 3y = -9

Now we add straight down and combine like terms

The y terms cancel and we are left with 3x = 9, dividing both side by 3 we get x = 3

Now we can plug this x value into one of the original equations to solve for our y value

I will use the first equation: 5(3) + 3y = 18 → condensing the terms we get  15 + 3y = 18 → subtracting the 15 from both sides we get 3y = 3 → dividing both sides by 3 we get y = 1

The solution to this system of equations is (3, 1)

Answer: 4,187 in3

Step-by-step explanation:

Hi, to answer this question we have to apply the next formula:

Volume of a sphere: 4/3 π (diameter /2)^3

Replacing with the values given;

V = 4/3 (3.14) (20/2)^3 = 4/3 (3.14) 10^3 =4,187 in3

The volume of the sphere is 4,187 cubic inches.

Feel free to ask for more if needed or if you did not understand something.

Answer:

6 cm ^2

Step-by-step explanation:

Answer:

The surface area is 6 cm².

Step-by-step explanation:

Given that a cube has side lengths all the same. Then you have to use surface area formula, S.A = 2(length×width) + 2(length×height) + 2(width×height) :

Let length = 1cm,

Let width = 1cm,

Let height = 1cm,

[tex]s.a = 2(1 \times 1) + 2(1 \times 1) + 2(1 \times 1)[/tex]

[tex]s.a = 2 + 2 + 2[/tex]

[tex]s.a = 6 \: {cm}^{2} [/tex]
