Answer: A
Step-by-step explanation:
Answer:
$1,665.19
Step-by-step explanation:
Interest=PRT/100 where P is the principal amount deposited by Michelle, R is the rate offered per year in terms of percentage, T is the period in years
Substituting P for $1385, T for 7 years, R for 2.89% we obtain interest as follows
Interest=$1,385*2.89*7 years/100=$280.1855
Balance after 7 years will be the sum of principal amount and interest gained
Balance=$1,385+$280.1855
=$1,665.1855
Rounding off to 2 decimal places
Balance=$1665.19
Therefore, Michelle's balance is $1,665.19
Answer:
v=12
Step-by-step explanation:
3v-8v+7v=24
3v-v=24
2v=24
v=12
Answer:
12
Step-by-step explanation:
so its at 12 visits because its their lowest common factor so i think it should be 12
Answer:
Type I error
Step-by-step explanation:
A type I error occurs if the null hypothesis is rejected when it is actually true.
Type I Type II
Reject null when true Fail to reject null when not true
Null hypothesis: ∪ = 30%
Alternative hypothesis: ∪ > 30%
The researchers concluded that more than 30% of first-grade students at this school have entered the concrete operational stage of development and they rejected the null hypothesis.
However, a census actually found that in the population of all first graders at this school, only 28% have entered the concrete operational stage.
A type I error has been made because in actuality the null hypothesis was true but was rejected.
