Answer:
5,500 units
Explanation:
Given that
Beginning units = 900 units out of one third is completed i.e = 300 units
Started and completed units = 5,000 units
Ending units = 800 units out of one fourth is completed = 200 units
So, according to the weighted average valuation method, the equivalent units is
= 300 units + 5,000 units + 200 units
= 5,500 units
This is the answer but the same is not provided in the given options
Answer:
The rate of change in 6 months is 14.87%
Explanation:
Let a be the amount that the money is multiplied in one month. We know that in 30 months it is multiplied by 2, so if we power a by 30 wew obtain 2:
a³⁰ = 2
Thus, 2 = a³⁰ = a⁶*⁵ = (a⁶)⁵
(here we use the propiety a^bc = (a^b)^c = (a^c)^b)
We can conclude that a⁶ = 2^(1/5) = 1.1487
The rate in 6 months is (1.1487-1)*100 = 14.87%
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.
