The difference between an algebraic expression and a numerical expression is that algebraic expressions contain numbers and variables. Numerical expressions only contain numbers. 

Ex:
Algebraic Expression- 5x+9
Numerical Expression- 4+2

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

How do we find P(rolling 2 or 5) with one number cube?
Allisa [31]
<span>The sample space of the rolling the cube is 6.
 The probability of rolling 2 in a cube is 1. So p(2) is 1/6
Similarly the probability of rolling 5 in cube is 1.
 So, p(5) = 1/6
To find p (2 or 5) which is p(2) + p(5)
p(2) + p(5) = 1/6 + 1/6 which is 2/6.
2/6 can be reduced to 1/3.
  so right answer is 1/3</span>

What is the slope of the line that passes through the points (-9, 2)(−9,2) and (1, 27) ?(1,27)? Write your answer in simplest fo
Cloud [144]

Answer:

pls mark brainliest if possible:

slope is 1.5

Step-by-step explanation:

Slope = rise over run = (y2-y1)/(x2-x1)

choose y2 and corresponding x-coordinate is x2. If we choose 27 as y2, then:

x2 = 1

x1 = -9

y1 = 2

then plug everything into the equation

(27-2)/(1-(-9))

=15/10

= 1.5

slope is 1.5

hope this helps!

Simplify completely 5x3+10x2+15x/5x
vlabodo [156]

Answer:

x²+2x+3....

Step-by-step explanation:

The given expression is:

5x3+10x2+15x/5x

To simplify this expression take out the common of the numerator:

5x is common in all three terms of the numerator:

Like,

5x(x²+2x+3)/5x

Now the value of the common and the denominator is same. Therefore 5x will be cancel out by 5x

Then the remaining term is:

= x²+2x+3

Thus the answer is  x²+2x+3....
