Answer:
14.4 m / s
Step-by-step explanation:
=distance between the car
=0.8 × 9
=7.2m
=time taken
=0.5s
=speed
=distance/time
=7.2m/0.5s
=14.4 m / s

Answer b is definitely the correct one.
The Empirical Rule states that 68% of normally distributed data lies within 1 standard deviation of the mean; 95% within 2 standard deviations, and 99.9% within 3.
Answer:

Step-by-step explanation:
For calculating the sales tax of a product, it is required to first multiply the original cost price of the product by the sales tax percentage.
Once the sales tax has been computed add it to the original cost price in order to determine the total cost of the product.
The formula of final amount is:

Here,
A = final amount
P = original cost price
S = sales tax percentage
Answer:Step-by-step explanation:
If there is a sequence and if we are to find its 87th term we must have the general term formula for the sequence.
Normally for sequences which follow a pattern there will be a formula for nth term.
Example is arithmetic sequence nth term = a+(n-1)d where a is the I term and d the common difference.
Similarly for geometric sequence nth term
= is the nth term
Thus to find the 87th term, we must be able to find out the pattern of the sequence by which any term is related to its previous term
Either general term formula or recurring formula should be given to get the 87th term
Step-by-step explanation: is arithmetic sequence nth term = a+(n-1)d where a is the I term and d the common difference. Still stuck? Get 1-on-1 help from an expert tutor now.
