6(4+7k)=-3k-6(4+k) k=?

Mathematics
1 answer:
Alona [7]3 years ago
3 0

Answer:

-16/15

Step-by-step explanation:

ok let's break this down.

6(4+7k) = 6*4 + 42k   (use distributive property)

3k - 6(4+k) = 3k - 24 - 6k     (do the same thing)

24 + 42k = 3k - 24 -6k  (let's simplify this a bit)

24+42k = -24-3k  (add 3k on both sides)

24+45k=-24 (subtract 24 on both sides)

45k = -48

k = -48/45 or -16/15

The probability distribution histogram shows the number of trees in yards in a certain neighborhood.
Vilka [71]

Answer:

45%

Step-by-step explanation:

Here, we want to know the probability of a randomly selected yard having 6 or more than 6 trees

To get this, we simply add up the probability of 6 yards and above

That is the probability of 6, 8 , 10 and 12 yards

This is obtainable from the histogram

We then proceed to add up from the graph

What we have is;

0.05 + 0.25 + 0.10 + 0.05

= 0.10 + 0.10 + 0.25 = 0.45

This is same as 45/100 which is otherwise 45%
