It took Amir 2 hours to hike 5 miles. On the first part of the hike, Amir averaged 3 miles per hour. For the second part of the

aivan3 [116]

Answer:

Times

first part x = 1,33 h second part y = 0,66 h

distances d₁ (first part ) d₁ = 4 miles d₂ (second part ) d₂ = 0,999 miles

Step-by-step explanation: IMPORTANT NOTE: EVEN PROBLEM STATEMENT DID NOT ASK ANY QUESTION WE WILL ASSUME QUESTION ARE: LENGTH ( IN MILES ) AND SPENT TIME OF EACH PART OF THE HIKE

We formulate a two-equation system according to:

x = time for the first part

y = time for the second part

then x + y = 2 or y = 2 - x

And 3 m/h * x(h) + 1,5 m/h * y (h) = 5

3*x + 1,5*y = 5

3*x + 1,5 * ( 2 - x ) = 5

3*x + 3 - 1,5*x = 5

1,5*x = 2

x = 2/1,5 (h)

x = 1,33 (h)

And y = 2 - 1,33 y = 0,66 (h)

Distances are

first part d₁ = 3*1,33 d₁ = 4 miles

second part d₂ = 1,5*0,66 d₂ = 0,999 miles

Assume that you have a binomial experiment with p = 0.5 and a sample size of 100.

Shalnov [3]

Answer:

Option D) 50

Step-by-step explanation:

We are given the following information in the question:

p = 0.5

Sample size,n = 100

We have to find the expected value of the distribution.

Formula:

$E(X) = np$

Putting the values, we get,

$E(X) = 100\times 0.5 = 50$

The expected value of this distribution is 50.
