Use the bar graph to find the experimental probability of the event.

Mathematics
1 answer:
julsineya [31]3 years ago
7 0

Answer:

Add total rolls:

The number of rolls is the height of each bar:

14 + 12 + 16 + 15 + 13 = 70

70 total rolls

The numbers greater than 3 are 4 and 5

4 was rolled 15 times and 5 was rolled 13 times

15 + 14 =28 Total times

The probability of that happening would be 28/70 which reduces to 2/5

The answer as a fraction is 2/5 which is 40% as a percentage.

IF your graph matches this data :)

Determine if the leading coefficient of the following function is positive or negative and whether the function has a minimum or
fenix001 [56]

Answer:

The function has a negative leading coefficient and a maximum vertex point

Explanation:

This function's leading coefficient is determined by whether it is concave up or concave down, meaning it has an Up and Up end behavior for a positive leading coefficient and a Down and Down end behavior for a negative coefficient.

This function's end behavior is Down and Down, so it must have a negative leading coefficient.

The function has a minimum vertex when the function has a positive leading coefficient and a maximum vertex point when the function has a negative leading coefficient.

This means that the functions vertex is the highest or lowest possible value of the function (the rest of the function continues forever in whichever direction.

This particular function has a maximum vertex as there is no point above the vertex here and the function has a negative leading coefficient.

8 was dividedby some numberthen added to13.next this difference was multiplied by 2 which gave a product of 30 find the answer
Anna11 [10]
The answer is 4. 

8/x +13 = y        -------->  y * 2 = 30 

divide 2 on both sides so y = 15

8/x + 13 = 15 
      - 13     - 13 

8/x = 2 

x =4

ABCDEFGHIJ is a regular decagon and the measure of <D is 144º. What is the measure of <A?
AnnyKZ [126]

Answer:

1. 144⁰

2. 60⁰

Step-by-step explanation:

The formula to find the measure of the interior angles of a regular polygon is:

m< = (n - 2) • 180/n where n = the number of sides

For a decagon, there are 10 sides.

m< = (10-2) • 180/10 = 144°

A regular polygon/equilateral triangle is defined as having equal sides and angles.
