Answer:0.3

Step-by-step explanation:

(7x+0.1)+(10x-0.2)= 17x-0.1

17x-0.1=5

17x=5.1

x=5.1/17

x=0.3

Answer : The value of 'x' is, 0.3

Step-by-step explanation :

Given:

Length of AN = 5 unit

Length of AM = 7x+0.1

Length of MN = 10x-0.2

Now we have to determine the value of 'x'.

Length of AN = Length of AM + Length of MN

Now put all the given values in this expression, we get the value of 'x'.

5 = (7x+0.1) + (10x-0.2)

5 = 7x + 0.1 + 10x - 0.2

5 = 17x - 0.1

5 + 0.1 = 17x

5.1 = 17x

x = 5.1/17

x = 0.3

Therefore, the value of 'x' is 0.3

Suppose the number of hits a webpage receives follows a Poisson distribution. The average number of hits per minute is 2.4.

JulijaS [17]

Answer: a) P(x=0) = 0.0907, b) P(x≥10) = 0.7986

Step-by-step explanation: the probability mass function of a possion probability distribution is given as

P(x=r) = (e^-λ)×(λ^r) /r!

Where λ = fixed rate at which the event is occurring and each event is independent of each other = 2.4

a) P(x= at least one) = P(x≥1)

P(x≥1) = 1 - P(x<1)

But P(x<1) = P(x=0) { we can not continue to negative values because our values of x can only take positive values of integer}

Hence, P(x≥1) = 1 - P(x=0)

P(x=0) = e^-2.4 * 2.4^0/(0!)

P(x=0) = 0.0907×1/1

P(x=0) = 0.0907

b) if the average number of hits in 1 minutes is 2.4 then for 5 minutes we have 2.4×5 = 12.

Hence λ = 12.

P(x= at least 10) =P(x≥10) = 1 - P(x≤9)

P(x≤9) will be gotten using a cumulative possion probability distribution table whose area is to the left of the distribution.

From the table P(x≤9) = 0.2014.

P(x≥10) = 1 - 0.20140

P(x≥10) = 0.7986

The weight of a beg of pears at the local market averages 8 pounds with a standard deviation of 0.5 pound. The weight of all the

Blababa [14]

Mean weight of the bag of pears = u = 8 pounds
Standard deviation = s = 0.5 pounds

We have to find what percentage of bags of pears will weigh more than 8.25 pounds. This can be done using the z score.

We have to convert x = 8.25 to z scores, which will be:

$z= \frac{x-u}{s}= \frac{8.25-8}{0.5}$

z score = 0.5

From the z table, the probability of z score being greater than 0.5 is 0.3085

Therefore, the probability of a bag to weigh more than 8.25 pounds is 0.3085

Thus 0.3085 or 31% (rounded to nearest integer) of bags of pears will have weight more than 8.25 pounds at the local market.
