A student is trying to solve the system of two equations given below: Equation P: a + b = 6 Equation Q: 4a + 2b = 19 Which of th

Marrrta [24]

Answer:

$-4(a + b = 6)$

Step-by-step explanation:

Given

$a + b = 6$

$4a + 2b = 19$

Required

Eliminate a

Multiply the first equation by -4

$-4(a + b = 6)$

Add to the second equation

$-4(a + b = 6) + (4a + 2b = 19)$

Solve brackets

$(-4a -4b = -24) + (4a + 2b = 19)$

Open bracket

$-4a + 4a -4b + 2b = -24 + 19$

$-4b + 2b = -24 + 19$

At this point, a has been eliminated;

From the list of given options, the option that answers the question is $-4(a + b = 6)$

Answer:

When the machine indicates a lie, what is the probability that the suspect is really lying? If the machine does not indicate a lie, what is the probability that the suspect is really telling the truth?

My solution if the probability that a test subject is chosen at random from the 200 in fact lie = 80/(80+5)=0.94

Then when 15% of people arrested lie, the probability that the suspect is really lying is 0.15*0.94=0.141

Baby anna wants to arrange 12 blocks in a row

12 blocks are arranged in a row having 12 places

---- , ---,---- , ---,---- , ---,---- , ---,---- , ---,---- , ---

12 blocks can be used in first place. 11 blocks can be used in second place.

10 blocks can be used in third place and so on

12, 11, 10, 9, 8, 7, 6, 5, 4 ,3, 2, 1

12 * 11 * 10 * 9 * 8 * 7 * 6 * 5 * 4 * 3 * 2 * 1 can be written as 12!

12! = 12 * 11 * 10 * 9 * 8 * 7 * 6 * 5 * 4 * 3 * 2 * 1 = 479,001,600

She can make 479,001,600 different arrangements.
