Vinil7 [7]2 years ago
7 0

Answer:

option B

4/11

Step-by-step explanation:

Given the word "probability" in the question

To find the probability of selecting letter 'b' or 'i' we will use following formula

probability = favourable outcome / total number of outcome

<h3>Total number of outcome = 11</h3><h3>favourable outcome = 4 </h3>

plug the values in the formula

The probability that a "b" or "i" is chosen = 4/11

The side length of a square ice cube is claimed to be 1.0 inches, correct to within 0.001 inch. Use linear approximation to esti
Olenka [21]

Answer:

0.012

Step-by-step explanation:

Linear approximation says that,

f(x) \approx f(x_o)+f'(x_o)(x-x_o)

For a cube the surface area is 6x^2.

So the side is 1.0 inch in, the surface area is =6\times1^2 = 6 square inches.  

In Linear approximation means you ignore the term x_o^2 , if x_o is a small number, because then x_o^2 will be a very smalle number and that does not contribute much to the error.  

So the surface area is approximately,

6x^2=6x_o^2+12x_o(x-x_o)

So here, x=1.001, x_o=0.001

The error in the area is approximately,

12 \times 0.001=0.012

So the error is 0.012.

Find the present balance.
Triss [41]
<h3>Credited balance:-</h3>

\\ \rm\longmapsto 115.90+115.90+345.85

\\ \rm\longmapsto 231.80+345.85

\\ \rm\longmapsto 577.65

<h3>Debited amount:-</h3>

\\ \rm\longmapsto 25.85+2.00

\\ \rm\longmapsto 27.85

<h3>Checked amount:-</h3>

\\ \rm\longmapsto 19.45+21.02+95.98

\\ \rm\longmapsto 117+19.45

\\ \rm\longmapsto 136.45

<h3>Total change in balance</h3>

\\ \rm\longmapsto 577.65-(27.85+136.45)

\\ \rm\longmapsto 577.65-191.3

\\ \rm\longmapsto 386.35

Now

<h3>Current balance</h3>

\\ \rm\longmapsto 386.35+271.31

\\ \rm\longmapsto\$ 657.66
