I'm assuming that the line is JKL in order of the points from left to right.

JK + KL = JL
(17-x) + (2x-7) = JL
Simplify.
10-x = JL

There are 250 freshman at Central High School. You survey 50 randomly selected freshman and find that 38 plan to go to the schoo
mestny [16]

Answer:

190 freshman will probably go to the party

Step-by-step explanation:

first we have to get the probability of a person going

for this we will see those who said they will go on those who asked them

38/50 = 0.76 = 76%

Now we are going to multiply the 0.76 by the 250 people, and we will obtain the probable number of freshman that come to the party

250*0.76 = 190

In a popular online role playing game, players can create detailed designs for their character's "costumes," or appearance. Lata
Artist 52 [7]

Answer:

52/79

Step-by-step explanation:

One costume = 156 (This is our numerator.)

All visitors = 156 + 58 + 23 = 237 (This is our denominator.)

156/237

Find the GCF to simplify (sneak peek it's 3)

156/3 = 52

237/3 = 79

52/79 (tada!)

59pounds * 5days = 295pounds

6.95pounds * 3breakfasts = 20.85pounds

Matrix multiplication was used to encode a message using the given encoding matrix: [i 47 A=1 |-1 -3] The original message was c
nadya68 [22]

Answer:

A^{-1}=\left[\begin{array}{cc}-3&-4\\1&1\end{array}\right] message SHOW_ME_THE_MONEY_  

Step-by-step explanation:

The matrix

A=\left[\begin{array}{cc}1&4\\-1&-3\end{array}\right]\rightarrow |A|=(1 \times -3)-(-1\times 4)=1\\\rightarrow A^{-1}=\left[\begin{array}{cc}-3&-4\\1&1\end{array}\right] \\

We can check that in fact A*A^⁻1=I_2 the identity matrix of size 2 x 2.

Now the message was divided in 1 x 2 matrices, then we have that the sequence given is the result of multiplying m by A, so to get m again we multiply now by A^⁻1. and we get the next table

Encoded message    Decoded message    message in letters by association

11 52        19 8    S H

-8 -9         15 23  O W

-13 -39        0 13   _ M

5 20         5 0   E _

12 56        20 8    T H

5 20         5 0    E _

-2 7           13 15  M O

9 41         14 5   N E

25 100       25 0    Y _

Then the message decoded is SHOW_ME_THE_MONEY_
