Answer:

$\large\boxed{y=\dfrac{-9x-2}{5}}$

Step-by-step explanation:

$9x+5y=-2\qquad\text{subtract}\ 9x\ \text{from both sides}\\\\5y=-9x-2\qquad\text{divide both sides by 5}\\\\y=\dfrac{-9x-2}{5}$

B) Express 0.6363......as a rational number in its lowest term.

bulgar [2K]

Answer:

$\frac{7}{11}$

Step-by-step explanation:

We require 2 equations with the repeating digits (63) placed after the decimal point.

let x = 0.636363..... (1) multiply both sides by 100

100x = 63.6363... (2)

Subtract (1) from (2) thus eliminating the repeating digits

99x = 63 ( divide both sides by 99 )

x = $\frac{63}{99}$ = $\frac{7}{11}$ ← in simplest form

According to a study, an average of six cell phone thefts is reported in San Francisco per day. Assume that the number of report

lions [1.4K]

Answer:0.29

Step-by-step explanation:

An average of six cell phone thefts is reported in San Francisco per day. This means our mean value, u = 6

For poisson distribution,

P(x=r) = (e^-u×u^r)/r!

probability that four cell phones will be reported stolen tomorrow=

P(x=4)= (e^-6×6^4)/4!

= (0.00248×1296)/4×3×2×1

= 3.21408/24=

0.13392

P(x=5)= (e^-6×6^5)/5!

= (0.00248×7776)/5×4×3×2×1

= 19.28448/120

= 0.1607

probability that four or five cell phones will be reported stolen tomorrow

= P(x=4) + P(x=5)

= 0.13392 + 0.1607

= 0.294624

Approximately 0.29

An urn contains n balls, one of which one is special. If k of these balls are withdrawn one at a time, with each selection being

Aleksandr [31]

Using it's concept, it is found that the probability that the special ball is chosen is given by:

$p = \frac{1}{C_{n,k}}$

<h3>What is a probability?</h3>

A probability is given by the <u>number of desired outcomes divided by the number of total outcomes</u>.

The total number of outcomes is given by the combination of k balls from the set of n balls, given by:

$C_{n,k} = \frac{n!}{k!(n - k)!}$

One ball is special, hence the probability the special ball is chosen is given by:

$p = \frac{1}{C_{n,k}}$
