Shown is a pentagon, with the size of<br> each angle shown. Work out the largest angle.

algol13

Answer:

I think it would be the bottom left angle, x + 20 = 20x.

Why the others are smaller:

10x (x + 10)

12x (2x + 10)

10x (x + 10)

A variable is normally distributed with mean 6 and standard 2 deviation .

Tju [1.3M]

The normal distribution is also known as the Gaussian distribution. The percentage of all possible values of the variable that are less than 4 is 15.87%.

<h3>What is a normal distribution?</h3>

The normal distribution, also known as the Gaussian distribution, is a symmetric probability distribution about the mean, indicating that data near the mean occur more frequently than data distant from the mean. The normal distribution will show as a bell curve on a graph.

A.) The percentage of all possible values of the variable that lie between 5 and 9.

P(5<X<9) = P(X<9) - P(5<X)

= P(z<1.5) - P(-0.5<z)

= 0.9332 - 0.3085

= 0.6247

= 62.47%

B.) The percentage of all possible values of the variable that exceed 1.

P(X>1) = 1 - P(X<-2.5)

= 1-0.0062

= 0.9938

= 99.38%

C.) The percentage of all possible values of the variable that are less than 4.

P(X<4) = P(X <4)

= P(z<-1)
= 0.1587

= 15.87%

Plz tell me how u got it and hurry please

Studentka2010 [4]

Because the shape is a cube, we know that all sides must be 5cm. To find the area of a side, you do base × height, so 5 × 5 = 25. If you look at the net, you'll notice that there are 6 faces, which means you have to do 25 × 6 = 150cm^2. I hope this helps!

Please explain your answer as well, THANKS!!!

Answer:

11,232,000

Step-by-step explanation:

The key to this problem is knowing "repetition is NOT ALLOWED".

<u>For the first 3 letters slot:</u>

For the 1st slot, we can pick any of the 26 alphabets

For the 2nd slot, we can pick any of the 25 remaining alphabets (since 1 is already taken)

For the 3rd slot, we can pick any of the 24 remaining letters (since 2 is already taken)

<u>For the three digits slot:</u>

For the 1st slot, we can pick any one of the 10 digits

For the 2nd slot, we can pick any one of the 9 digits left, since 1 is taken already

For the 3rd slot, we can pick any one of the 8 digits left, since 2 is already taken

The number of license plates, thus, would be all of these multiplied together:

26 * 25 * 24 * 10 * 9 * 8 = 11,232,000
