G=number of words on george's page
b=number of words on bill's page
c=number of words on charlie's page
george has 2 times as many as bill's age
g=2b
bills contains 50 less than charlie
b=c-50
if each person can type 70 words per minute, after 1 minute (that is an additional 70 words for each person)
the difference between twice nmber of words on bill's page and the number of words on charlie's page is 220
so
that is after increase of 70 words
2(b+70)-(c+70)=220
and
b=c-50
subsittute
2(c-50+70)-(c+70)=220
2(c+20)-c-70=220
2c+40-c-70=220
c-30=220
c=250
charlie had 250 initially
b=c-50
b=250-50
b=200
bill had words 200 initially
who cares about george
ANSWER:
70, 000
67, 000 rounded to the nearest ten thousand is: 70, 000.
EXPLANATION:
As we are rounding the number to the nearest ten thousand, we will look at the thousand digit of the number in order to decide whether to round the number up or down. As the thousand digit is 7, we must round the ten thousand digit up meaning that the 6 would become a 7. Therefore, the answer would be 70, 000.
The objective of Exploratory Research research is to gather preliminary information that will help define the problem and suggest hypotheses.
Exploratory Research is a methodology approach that explores research
question that have not previously been studied in depth.
The nature of experimental studies is generally frequently qualitative. However, an investigation with a big sample size might also be quantitative. Due to its open-mindedness and flexibility, it is additionally commonly referred to as interpretivism or a grounded theory method.
It is commonly employed when the subject you're examining is new, or perhaps the data collection method is challenging in certain way.

Answer:
interval in minutes = (24.88, 35.12)
Step-by-step explanation:
we can use the following formula:
interval = population mean ± (z · σ)
- population mean = 30 minutes
- z for 80% = 1.28
- σ = 4 minutes
interval = 30 minutes ± (1.28 · 4 minutes)
interval in minutes = (30 - 5.12), (30 + 5.12) = (24.88, 35.12)
