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.

Answer:
e) $4,651
Explanation:
The break-even point is the level of activity that a company must operate to have its total cost equal to its total revenue. At this level of activity, the business makes a zero profit, as the total contribution is exactly the same as the total fixed cost.
It is important for the business to have an idea of the number of customers or units of product to sell inorder for it to cover its total fixed cost. This is the information the break-point analysis seeks to provide.
Working it out
Break-point in sales = Total General fixed cost/ Contribution margin ratio
Contribution margin ratio (CMR): Contribution is sales less variable costs. And the contribution margin ratio is the proportion of sales that is earned as contribution. The higher the better.
CMR = contribution/sales
Fixed cost = Contribution + net loss
We can now apply all these relationships to the question given:
Fixed cost = 1720 + 280
= 4,000
Contribution margin ratio = 1720/400 = 43%
Break-even sales ($) = 4000/0.43
= $4,651
Answer:
P = $75 per club
n= 75,000 clubs
Explanation:
The demand and supply functions are:
The equilibrium price is the price that yields a quantity demanded equal to the quantity supplied:
The number of units sold at that price is:
Answer:
The ending balance in the Allowance for Bad Debts is 20,500 CREDIT
Explanation:
The ending balance of Allowance for bad debts would be the 2.5% of sales
The adjustment is made to get the allowance for Bad Debt match the estimate uncollectible ammounts.
Notice it state <em>"company adjusted for bad debt expense"</em>
This means<u> it debit this account as much as it needed to be</u> to make allowance match the estimate allowance.
The write-off are transaction durign the period. They are irrelevant
So the ending balance is:
<em>2.5% of credit sales of 820,000 = $20,500</em>
It is important to remember that <u>Allowance is a counter-asset account</u>. His <em>normal balance is credit</em>, so the<u> final balance is credit.</u>
The average score of the student in the class at a 99% confidence lies between 1.252 and 3.028
Explanation:
Given values are
n = 14 = 2.14 σ = 1.29 z value for 99% confidence = 2.576
The mean is known one
= (z σ/√14)
= (2.576 ×1.29÷√14)
= 2.576 × 0.345
= 0.888
= mean- 0.888 = 2.14 - 0.888 = 1.252
= mean+0.888 = 2.14 + 0.888 = 3.028
The average score of the students in the class at a 99% confidence lies between 1.252 and 3.028
