Answer:
Initial P, principal value is $3000
Year 1: P(1)= 3000 + 3%(3000)
P(1)= 3090
Year 2: P(1)= 3090 + 3%(3090)
P(1)= 3182.70
etc.
So in year 10, using the formula for compound interest, P(t)= P(1.03)t
P(10)= 3000(1.03)10
= 4031.75
Step-by-step explanation:
so, there were in total 63 + 7 = 70 questions.
therefore,
100% = 70
1% = 100%/100 = 70/100 = 0.7
to know how many % are the 63 correct answers we need to divide 63 by 1% :
63 / 0.7 = 90%
so, he got 90% correct.
First....6÷1/2= 12
so.....12*3.9=46.8 milligram
Answer:
Decimal:0.625 Fraction:5/8
Step-by-step explanation:
First we divide 5 and 8 and you get 0.625 by doing that and then to get its fraction form you turn it to a fraction which is 5/8.
Sorry if this wrong
The answer is Internal Validity.
Internal Validity is high in an experiment. when it demonstrates persuasively that changes in behavior are caused by the independent variable and not by unknown factors.
What is Internal Validity?
- Internal validity is defined as the degree to which the observed results represent the truth in the population under investigation and are not the consequence of methodological flaws.
- Internal validity is the degree of certainty that the causal link being examined is reliable and unaffected by other factors or variables.
- The extent to which study results may be extended (generalized) to other contexts, groups, or events is referred to as external validity.
