Area = Pi * r^2
'
r = 7 / 2 = 3.5

area = 3.14 * 3.5^2
area = 3.14 * 12.25
area = 38.465 m sq

The number 3456 is divisible by wich single-digit number?

Gnesinka [82]

I'm assuming what you mean is what can you divide 3456 by to get a natural number.

First of all every number is divisible by 1.

Every even number is divisible by 2, so since 3456 is an even number, it can be divided by 2. That would equal 1728.

2456 can also be divided by 3, to get 1782.

You can also divide it by 4, to get 865.

Divided by 6, it's 576.

Divided by 8, it's 432.

And lastly, 3456 divided by 9 is 384.

So, there isn't just one single-digit number you can divide 3456 by to get a natural number. You can divide it by 1,2,3,4,6,8, and 9.

Hope that helps!

ohn is interested in purchasing a multi-office building containing five offices. The current owner provides the following probab

Galina-37 [17]

Answer:

$28,875

Step-by-step explanation:

The given table is:

$\left|\begin{array}{c|cccccc}$Number of Lease Offices&0&1&2&3&4&5\\$Probability&5/32&3/16&3/32&1/4&9/32&1/32\end{array}\right|$

The expected probability is derived using the formula: $\sum_{i=0}^{5}x_iP(x_i)$

Therefore, for the given distribution,

Expected Probability

$=(0*\frac{5}{32})+ (1*\frac{3}{16})+ (2*\frac{3}{32})+ (3*\frac{1}{4})+ (4*\frac{9}{32})+ (5*\frac{1}{32})\\=2.40625$

If each yearly lease is $12,000

The Expected Yearly Lease for the Whole Building=2.40625 X 12000

=$28,875
