Answer:

T must be 3/(3+1) or 3/4ths of the way between point d and f.

Take (dx, dy) and add 3/4 (fx-dx, fy-dy) by components and that will be point T (Tx, Ty)

You find the distances between d and f in x and y and then move 3/4 of that distance from d.

Step-by-step explanation:

Im not too sure, I got the answer from my last test. It might be wrong

What is the sum of the sequence 152,138,124, ... if there are 24 terms?

N76 [4]

Answer: -216

Step-by-step explanation:

To solve the exercise you must use the formula shown below:

$Sn=\frac{(a_1+a_n)n}{2}$

Where:

$a_1=152\\a_n=a_{24}$

You should find $a_{24}$

The formula to find it is:

$a_n=a_1+(n-1)d$

Where d is the difference between two consecutive terms.

$d=138-152=-14$

Then:

$a_{24}=152+(24-1)(14)=-170$

Substitute it into the first formula. Therefore, you obtain:

$S_{24}=\frac{(152-170)(24)}{2}=-216$

What is the pobability that a number cube with six

Snowcat [4.5K]

Answer: $\dfrac{1}{6}$

Step-by-step explanation:

We know that the total number of outcomes for fair dice {1,2,3,4,5,6} = 6

Given : Favorable outcome = 5

i.e. Number of favorable outcomes =1

We know that the formula to find the probability for each event is given by :-

$\dfrac{\text{Number of favorable outcomes}}{\text{Total outcomes}}$

Then, the probability that the six faces cube will land with the number 5 face up will be :_

$\dfrac{1}{6}$

Hence, the required probability = $\dfrac{1}{6}$
