Jessie colered a poster. She colered 2/5
muminat
Only you have to multiply by a number the numerator and denominator.
2n/5n;  n∈N (N=1,2,3,....;)
Therefore:
if n=2 ⇒2*2/5*2=4/10
if n=3 ⇒2*3/5*3=6/15
if n=4 ⇒2*4/5*4=8/20...

therefore, 4/10 ,6/15, 8/20

A company manufactures cd drives that sometimes experience disc-read errors. if a cd drive is tested for 250 read operations and
andre [41]

The probability that a Cd drive will fail is 1.6 %.

<h3>What is probability?</h3>

Probability is the branch of mathematics concerning numerical descriptions of how likely an event is to occur, or how likely it is that a proposition is true. The probability of an event is a number between 0 and 1, where, roughly speaking, 0 indicates impossibility of the event and 1 indicates certainty.

Given,

Cd tested = 250 read operations

Cd fails = 4 times

probability = \frac{Number of favourable outcomes}{Number of total outcomes}

here we have,

Probability = 4/250

= 0.016

= 0.016 × 100

= 1.6 %

Find the length of BC​
Likurg_2 [28]

Answer:

BC = 88.88

Step-by-step explanation:

Comment.

This looks like an example of the cos law.

Givens

AB = 100 m

<A = 60 degrees

AC = 70 m

Cos(60) = 1/2

BC = ?

Formula

BC^2  = AB^2 + AC^2 - 2*AB*AC * Cos(60)

Solution

BC^2 = 100^2 + 70^2 - 2*100*70 * 1/2     1/2 and 2 cancel out

BC^2 = 10000 + 4900 - 7000      

BC^2 = 7900                                             Take the sqr root of both sides

√BC^2 = √7900

BC = 88.88
