Answer:

Step-by-step explanation:

Use the cosine rule and see if the numbers hold true. a^2 = b^2 + c^2 - (2bc (cos x))

By substituting in our values I get that cos x = 0.838... which is possible. If cos x would equal 1.5, the there is no solution and the triangle would not be possible.

If you know the equation of a proportional relationship how can you draw the graph of the equation

zalisa [80]

The equation of proportional relationship is of the form:
$y(x)=mx$

where m is the slope.

Drawing it is fairly easy, you start from the origin (0, 0) and you draw a diagonal staight line. The inclination of the line depends on the value of m. See picture attached.

Liz flips a coin 50 times. The coin lands heads up 24 times and tails 26 times. Based on Liz’s results, what is the experimental

Sliva [168]

Answer:

48%

Step-by-step explanation:

First, lets start with what we know.

Coin was flipped 50 times. Landed Heads 24 times, and landed tails 26 times.

Now, we want this in a percentage. So:

24 = x

50 = 100

We know that 50 is 100/2. So, we can multiply both of the numbers to get a percentage.

24 × 2 = 48

26 × 2 = 52

In conclusion, the experimental probability for the coin landing on heads is:

48/100 OR 48%
