Answer:
200.3 cm
210 cm
Step-by-step explanation:
to find the mean add all the numbers up and then divide it by the total number sampled
so we have
(198+199*3+200*2+201*5+202*2)/13
which gives you around 200.3
To find the height of the new player we have the following equation
let x be the height of the new player
solve for x and get
210 cm
i’m sorry i just really need this
There are two triangles: a small one to the left and a big one, which includes the small one. They both have a common angle (the leftmost angle) and since (we can assume) the two columns meet the floor at right angles, they both have two equal angles. This means they are similar (AAA).
Let the distance of the base of the stairs to the tallest column be d.
Because matching sides of similar triangles are in the same ratio,
4 / 6 = d / (6 + 12)
4 / 6 = d / 18
(4 * 18) / 6 = d
d = 12
The answer is C
