Answer: mean= 16.9

Median= 14

Step-by-step explanation:

Mean= sum of data set/ number of data set

= 118/7 =16.9

Median- the middle number of a data set, to reflect the best measure of the centre, the data set should be arranged in an ascending order

12, 13, 13, 14, 21, 22,23...... 14 is the median

2)small one: legs - h,s, and hypotenuse - b.


Corresponding sides:

hypotenuse - c and hypotenuse - b,

big leg - b and big leg - s,

small leg - a, and small leg h.


?(/b(big leg, big triangle)= b(hypotenuse, small triangle )/s (big leg, small triangle)


? should be hypotenuse of the big triangle, c.

Can someone check if this is right or did I solve it wrong?
ICE Princess25 [194]

Answer:

f(3x) - 2g(x+1) = 12x - 5

Step-by-step explanation:

You've got f[g(x)] and g[f(x)] correct

However, f(3x) means substitute 3x for x in f(x):

f(3x) = 2(3x) - 3

⇒ f(3x) = 6x - 3

2g(x+1) = 2[4 - 3(x + 1)]

⇒ 2g(x+1) = 2[4 - 3x -3]

⇒ 2g(x+1) = 2[1 - 3x]

⇒ 2g(x+1) = 2 - 6x

f(3x) - 2g(x+1) = (6x - 3) - (2 - 6x)

⇒ f(3x) - 2g(x+1) = 12x - 5

Which expressions are equivalent to g+h+ (j+k)? Check all that apply.
Vsevolod [243]
According to the associative property of equality: (a + b) + c = a + (b + c) we can see that the parenthesis do not mean anything when we are only doing addition.

So answers 1. and 3. are correct.
