Answer:

$0.68

Explanation:

Multiply each possible prize by its likelihood and add the results in order to obtain the expected value (Note that there is a 100% of losing 0.57 cents since that is the cost of entry):

EV = 5200*\frac{1}{8900} +2500*\frac{1}{6400} +900*\frac{1}{3900}+100*\frac{1}{2100} -0.57*1\\EV= \$0.68

The expected value of the amount won for one entry if the cost of entering is 57 cents is $0.68

English language learners (ells), who are typically immigrant children, are at a greater risk for lower socioemotional and acade
forsale [732]

A study of the growth of English language learners (ELLs) in first-time kindergarten students (N = 19,890) from kindergarten through eighth grade was conducted.

Growth curve analyses showed that, when other factors were held constant, ELLs continued to improve at a steeper rate on these social/behavioral outcomes than their native English-speaking peers.

In kindergarten, teachers rated ELLs more favorably on approaches to learning, self control, and externalizing behaviors than native English speakers did.

Depending on the grade at which English competence is reached, ELLs and native English speakers achieve reading and math skills differently.

To be more precise, ELLs who were proficient by the time they entered kindergarten kept up with native English speakers in both reading and math initially and over time.

ELLs who were proficient by the time they entered first grade had modest gaps in reading and math achievement compared to native English speakers that either narrowed or persisted over time.

Learning English before entering kindergarten is associated with superior cognitive and behavioral results through the eighth grade for students whose first language is not English.

<h3>What is inventory?</h3>

Inventory, also known as stock, refers to the goods and materials that a company keeps for the purpose of resale, production, or use. Inventory management is primarily concerned with specifying the shape and placement of stocked goods.

There are four types of inventory: raw materials/components, work in progress (WIP), finished goods, and maintenance and repair (MRO).

Inventory valuation methods include FIFO (First In, First Out), LIFO (Last In, First Out), and WAC (Weighted Average Cost).

Manufacturers have three kinds of inventory. They are raw materials (that have yet to be worked on), work-in-progress (that is currently being worked on), and finished goods (which are ready for shipping).
