Multiple each term in the parentheses by 4 and the answer is 4x-4

Answer: x= -1

Step-by-step explanation:

First you take 4 and times it to x and -1, so 4 times x will just be 4x while 4 times -1 will be -4. Then it will look like this (4x - 4), you will have to make the x by itself and to do that is dividing it by 4 on both sides, so 4x/4= x while -4/4= -1. The answer is x= -1

Pleeeeease help me!!!

Hello!

We solve this algebraically

y + 6 = 3/2(x - 4)

We distribute the 3/2

y + 6 = 3/2x - 6

If you work with decimals easier we can make 3/2 into a decimal

y + 6 = 1.5x - 6

Add 6 to both sides

y + 12 = 1.5x

subtract y from both sides

1.5x + -y = 12

Hope this helps!

A 10 bit string is to be randomly picked from all possible 10 bit strings. What is the probability that you picked a string with
allochka39001 [22]

Answer: 0.9990

Step-by-step explanation:

Given : The number of bits in a string = 10

The value taken by a bit is either 0 or 1.

Therefore, the probability that the bit is zero = \dfrac{1}{2}=0.5

Binomial probability distribution formula :-

P(x)=^nC_xp^x(1-p)^{n-x}, where P(x) is the probability of getting success in x trials , n is the total number of success and p is the probability of getting success in each trial.

Now, the probability that you picked a string with at least one zero is given by :-

P(x\geq1)=1-P(z

Hence, the  probability that you picked a string with at least one zero = 0.9990
