The mean (average) of a data set is found by adding all numbers together and then dividing by the number of values in the set.

Median is the middle value when the numbers are ordered from least to greatest.

Solve for x: -5 < 8x + 11 < 19
vladimir1956 [14]

Answer:

-2<x<1

Step-by-step explanation:

-5 < 8x + 11 < 19

Subtract 11 from all sides

-5-11 < 8x + 11-11 < 19-11

-16 < 8x<8

Divide by 8

-16/8 < 8x/8 <8/8

-2<x<1

Sun, a kayaker, paddles 8 miles upstream (against the current) in 2 hours. Returning to her original location, she paddles downs
Softa [21]
We calculate both velocities:
upstream 8 miles in 2 hours = 4 miles / hour
downstream 8 miles in 1 hour = 8 miles / hour

ps -stream speed = 4 mph
ps + stream speed = 8 mph
Adding both equations
2 ps = 12 mph
paddling speed = 6 mph
stream speed = 2 mph

What is the answer to this question?
Vilka [71]

Answer: Choice A) 4, 3, 5, 1, 2

=====================================================

Explanation:

Since tan(x) = sin(x)/cos(x) is a known and widely used trig identity, this must mean step 4 goes first.

The answer is between choice A and choice B.

The question is now: What is the correct second step?

It's either step 3 (choice A) or step 5 (choice B)

It turns out that step 3 is the correct statement after step 4. The sin(2x) breaks up into 2sin(x)cos(x), while the cos(2x) breaks up into cos^2(x)-sin^2(x). There are three different variations for the cos(2x) and this just happens to be one of them.

So we can rule out choice B and go with choice A as the final answer.
