SVEN [57.7K]

Answer:

Volume of the hemisphere = \frac{2}{3}\pi r^{3}

Step-by-step explanation:

It's a picture of a globe and a globe of the Earth is in the shape of a sphere.

We know equator divides the earth into two equal halves and these equal halves are called as "hemisphere".

Therefore, a line joining the two extreme points of the diameter of the Earth divides the Earth into two hemispheres.

If the radius of the Earth is 'r',

Volume of the hemisphere = \frac{2}{3}\pi r^{3}

What is 15% of 75.50 and how did you get it
bekas [8.4K]
A percentage can just be written as a decimal where 100% = 1.00

15% = 0.15

75.5 * 0.15 = 11.325

You just multiply.

A GMC dealer believes that demand for 2005 Envoys will be normally distributed with a mean of 200 and standard deviation of 30.
irina1246 [14]

Answer:

The correct answer to the following question will be "280 units".

Step-by-step explanation:

The given values are:

Mean = 200

Standard deviation = 30

Let's ask that the supplier needs to reach 99.9% of the standard of operation. To reach this quality of operation, she has to preserve an inventory of

Now,

⇒  Mean + 3\times sigma

On putting the values, we get

⇒  200+3\times 30

⇒  200+90

⇒  290 \ units

290 units would then accomplish a level of service of 99.9%.

Half unpurchased units can indeed be purchased at $30000 i.e. no failure. If he requests 300, there will be losses on 5 products that are unsold.

Hence, ordering 280 units seems to be preferable

Help me with this please everyone
cupoosta [38]
First, let's simplify each expression by combining like terms:

A: 9x-3x-4 = 6x-4

B: 12x-4 = 12x-4 (Already Combined terms)

C: 5x+x-4 = 6x-4

When looking at the list of equations, it is clear that only Expression A and C are equivalent. Brianna failed to combine like terms and plug in more points than 0. 

I Hope this Helps!
