Notice that there's a pattern in the given sequence.
1, 4, 9, 16,............ can be written as 1², 2², 3², 4²,...............
So, the general term of the given sequence is y_{n}=(n)^{2}
Question
The table shows the heights in a basketball team.
Height: 198, 199, 200, 201, 202
a.) Work out the mean height of the team. Round you answer to 1d.p.
That, I have worked out is 200.3
b.) A new player joins the team and raises the mean average height to 201cm. Work out the height of the new player.
Answer:
206 cm
Step-by-step explanation:
The sum of the fiven numbers, 198+199+200+201+202=1000
For a mean of 201, the product should be 201*6=1206
The difference of the two is equivalent to the height of the other person hence 1206-1000=206 cm
Therefore, the height is 206 cm
Answer:
-2
this eq. can be simplified to -
y = 5 - 2x
we know that the coefficient of x is the slope
therefore , -2 is the slope
Answer: -4/15
Step-by-step explanation: To add these two fractions together,
we start by finding their <em>Least Common Denominator</em> (LCD).
Since our denominators of 5 and 3 have no factors in common,
our least common denominator is 5 · 3 or 15.
In order to get a denominator of 15 in each fraction,
we multiply top and bottom of the first fraction by 3
and top and bottom of the second fraction by 5.
That gives us -9/15 + 5/15 which simplifies to -4/15.
As your last step, make sure that the fraction
that you end up with doesn't reduce.
In this case, -4/15 does not reduce but watch out for this last step.
