A 5x2=10 I think it’s right
Answer:
2.33.
Step-by-step explanation:
First we find the mean by adding the values and dividing by 11 (the number of values).
mean = 62 / 11
= 5.636
Now, we list the absolute differences between each value and the mean:
9 - 5.636 = 3.364 the others are:
3.636, 3.636, 0.636, 2.636, 3.364, 0.364, 4.364, 1.636, 1.364, 0.636
Now the MAD is the sum of these values / 11.
MAD = 25.636/11
= 2.33..
Answer:
probably
D because they're both the same shape it's just D is smaller.
Step-by-step explanation:
1.all three sides are equal
2.2 sides and their included angle are equal
3.A pair of angles and their included side are equal
4.2 corresponding angles and their non included side are equal.
5.the hypotenuse and 1 leg of a right triangle equal.
Calculate the direction cosines, and hence find the angles.
unit vector
=<105,135,-175>/sqrt(105^2+135^2+(-175)^2)
=<21/sqrt(2395),27/sqrt(2395),-35/sqrt(2395)>
=<0.4291,0.5517,-0.7152> (approx.)
Therefore the direction cosines are respectively
0.4291,0.5517,-0.7152, and the angles with the x,y and z-axes are:
acos(0.4291),acos(0.5517),acos(-0.7152)
=64.59, 56.51, and 135.66 degrees respectively.
