Answer:
4.4
Step-by-step explanation:
x is hypotenuse of the right triangle.
One leg is 2.4 in.
Second leg = 7.4/2 = 3.7 in.
Using Pythagorean theorem
Hypotenuse²= (first leg)² + (second leg)²
x² = 2.4² + 3.7² = 19.45 in²
x=√19.45 ≈ 4.4 in
If you have a graphing calculator just put in the equation in 'y=' (not the i equation), and then go to 2nd trace and see where the y=0, those numbers under the x column are the zeros. For the first one, the zeros are: -1, .5, and 2.8. For the second question the zeros are: -3 and about 1.9. The zeros with a decimal are estimations.
Answer:
mean: 7.62
median: 8
mode: 9
Step-by-step explanation:
first you have to put the data set in order:
6,6,6,6,7,7,8,8,9,9,9,9,9
the mode is the most often repeated number in a data set so the mode in this data set would be 9. The median is the middle number in the data set. The middle number in this data set is 8. Lastly, the mean in a data set is all of the numbers in the data set added together and then divided by how many numbers are in the set. The equation for this data set would be 99/13= 7.62
hope this helps!!
9/200. divide 45 and 1000 both by 5 to reduce it.
