First is because it doesn't keep it's pattern

it goes from 10,15, 20 to 30. it should actually be 35

the second is accurate because it keeps going up by 50

Last year, a person wrote 123 checks. Let the random variable x represent the number of checks he wrote in one day, and assume

Sunny_sXe [5.5K]

Answer:The mean number of checks written per day = 0.3370

The standard deviation = 0.5805

The variance = 0.3370

Step-by-step explanation:

Let the random variable x represent the number of checks he wrote in one day.

Given : The number of checks written in last year = 123

Let the number of days in the year must be 365.

Now, the mean number of checks written per day will be :-

$\lambda=\dfrac{123}{365}=0.33698630137\approx0.3370$

We know that in Poisson distribution , the variance is equals to the mean value .

$\text{Thus , Variance }=\sigma^2= 0.3370$

$\Rightarrow\ \sigma=\sqrt{0.3370}=0.580517010948\approx0.5805$

Thus, Standard deviation = 0.5805

A belt and a pair of pants cost $490 altogether. A bag costs twice as much

m_a_m_a [10]

Answer:

$196

Step-by-step explanation:

Lets assume,

cost of a belt = 'x'

cost of a pair of pants = 'y'

Now, According to the question;

x + y = 490;
cost of a bag = twice the cost of belt = 2x;
cost of a pair of pants = twice the cost of bag

⇒ y = 2×2x ⇔ 4x

hence, by subtituting the values in equation' we get;

⇒ x + 4x = 490

⇒ 5x = 490

⇒ x = 98

So, the difference between the cost of the pair of pants and the bag ;

⇒ y - 2x

⇒ 4x - 2x

⇒ 2x = 2×98 = 196.
