Determine the measure of angle A

Mathematics
1 answer:
igor_vitrenko [27]3 years ago
6 0

Answer:

63*

Step-by-step explanation:

The first thing you need to do is find the value of x. What I did for this was trial and error. I tried a number, and if it was too big, I tried a smaller one. If you add up all of the angles, it should equal up to 180*, so I kept on doing this until I added up to 180.

The answer I got was x=8, so I plugged this into the equation for A and solved. 9x8 is 72, and 72-9 is 63.

Therefore, 63 is the correct answer.

AnnyKZ [126]

Answer:

Right skewed

Step-by-step explanation:

A skewed right distribution by definition is "one in which the tail is on the right side".Or on simple words when we have the following property:

Mode

Or equivalently:

Mean> Median>Mode

A skewed left distribution by definition is "one in which the tail is on the left side". Or on simple words when we have the following property:

Mode>Median>Mean

Or equivalently:

Mean< Median

And for this case we can see that Mean =75> Median =78

So on this case the best description for this distribution is right skewed.

bazaltina [42]

The graph that can represent the data most accurately is (a) The y-axis of a bar graph starts at zero fish. One bar is 24 units, another bar is 51 units, and the third bar is 36 units

The given parameters are:

  • Aquarium A: 24 fishes
  • Aquarium B: 51 fishes
  • Aquarium C: 36 fishes

The above dataset can be represented on a bar graph, where the lengths of the bars represent the number of fishes in each aquarium

Hence, the graph that can represent the data most accurately is (a)
