Consider the continuous random variable x, which has a uniform distribution over the interval from 110 to 150. The probability t
Virty [35]

Answer:

The probability that x will take on a value between 120 and 125 is 0.14145

Step-by-step explanation:

For uniform distribution between a & b

Mean, xbar = (a + b)/2

Standard deviation, σ = √((b-a)²/12)

For 110 and 150,

Mean, xbar = (150 + 110)/2 = 130

Standard deviation, σ = √((150-110)²/12 = 11.55

To find the probability that x will take on a value between 120 and 125

We need to standardize 120 & 125

z = (x - xbar)/σ = (120 - 130)/11.55 = - 0.87

z = (x - xbar)/σ = (125 - 130)/11.55 = - 0.43

P(120 < x < 125) = P(-0.87 < x < -0.43)

We'll use data from the normal probability table for these probabilities

P(120 < x < 125) = P(-0.87 < x < -0.43) = P(z ≤ -0.43) - P(z ≤ -0.86) = 0.33360 - 0.19215 = 0.14145

Hope this Helps!!!

Lexi had 3/4 of an apple pie. She gave 1/4 of what she had to her friend Julie. What fraction of the whole pie did Julie get?
Murljashka [212]

Answer:

<u>3/16 of the whole pie</u>

Step-by-step explanation:

Lexi had 3/4 of an apple pie. She gave 1/4 of it to Julie. That means what Julie receives is the product of the whole and the portion.

One brother eats 3/5and the other brother eat 3/10 of the cereal how much more does the other brother eat
WITCHER [35]
In this question there are information's of immense importance and that can go a long way in helping to solve the given question. It is given that one brother eats 3/5 of the cereal and the other brother eats 3/10 of the cereal. The answer that needs to be found is that the amount of cereal the other brother eats more.
The amount of cereal eaten more by the other brother = (3/5) - (3/10)
                                                                                       = ( 6 - 3)/ 10
                                                                                       = 3/10
So the other brother does not eat more, but the first brother has eaten 3/10 more than the other brother.
