Answer:
Company A is a better deal than Company B for the number of miles greater than 295 miles
Step-by-step explanation:
Let
y ----> the charge per week in dollars
x ----> the number of miles
we have
<em>Company A</em>
-----> equation A
<em>Company B</em>
-----> equation B
Solve the system by substitution
Equate equation A and equation B and solve for x


For x=295 miles the charge in Company A and Company B is the same
therefore
Company A is a better deal than Company B for the number of miles greater than 295 miles
Tim spends
of his TV time watching badminton.
Step-by-step explanation:
Step 1:
Tim watches a total of 8 sports. He spends
of his TV time watching the first four.
So first we need to calculate how much TV time is left to watch the remaining sports.
The TV time left to watch the other sports
.
So
of his TV time is spent equally on the other 4 sports.
Step 2:
As there are 4 sports remaining, he spends the
of his time on all four sports equally. We need to determine what that time is.
The time spent on the remaining four sports
.
So Tim spends
of his total TV time each on watching formula1 races, tennis, badminton and hockey games. So he spends
of his TV time watching badminton.

Answer:
(e) the mean number of siblings for a large number of students has a distribution that is close to Normal.
Step-by-step explanation:
Central Limit Theorem
The Central Limit Theorem estabilishes that, for a normally distributed random variable X, with mean
and standard deviation
, the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean
and standard deviation
.
For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.
By the Central Limit Theorem
The sampling distributions with a large number of students(at least 30) will be approximately normal, so the correct answer is given by option e.
