6 0

The number 43 has 4 tens and 3 ones.

Now we have 43 ones given, in order to regroup them, we need to group 4 rows of 10 each and 3 rows of 1 each.

By this, we will be having:
4 rows of 10 each = 4*10 = 40
3 rows of 1 each = 3*1 = 3
which is the needed 43.

Line AB is a directed segment with endpoints A(2,2) and B(14,14). In two or more complete sentences, explain how you would verif

Kisachek [45]

It is not recommended that points be marked with X, let's marked with C(6,6)=(Xc,Yc)

The coordinates of the point C(Xc,Yc) which belongs to the line AB and divides line AB in a ratio m : n = 1 : 2 or m/n=1/2 are get it with following formula

Xc=(Xa+(m/n)Xb) / (1+(m/n)) and Yc=(Ya+(m/n)Yb) / (1+(m/n))

We have A(2,2)=(Xa,Ya) and B(14,14)=(Xb,Yb)

When we replace given coordinates we get

Xc=(2+(1/2)*14) / (1+(1/2)) = (2+7) /(3/2) = 9/(3/2) = (9*2)/3 = 3*2 =6 => Xc=6

Yc=(2+(1/2)*14) / (1+(1/2)) = (2+7) / (3/2) = 9/(3/2) = (9*2)/3 = 3*2 =6 => Yc=6

C(Xc,Yc)=(6,6)

Good luck!!!

A high school is conducting a vote to see which class (freshman, sophomore, junior, or senior) can go to see a play performance.

Lady_Fox [76]

The probability of an event is considered fair when the probability of the event happening is equally likely.

Thus, the way each vote should be counted so that the outcome is fair is "The freshman votes count as 1 vote, the sophomore as 1.14 votes, the juniors as 1.45 votes, and the seniors as 1.23 votes."
