First one simplifies to 2x + 6 = 2x + 7  which can't be true   so this one has No Solution.
Same applies to the second equation  ( 5x + 15 = 5x - 15) No solution

also the last one has no solution because it simplifies to  4x + 20 = 4x + 19

P + 2q = 11<br>2p + q = 10​
poizon [28]

Answer:

p = 3

q = 4

Step-by-step explanation:

p + 2q  = 11          --------------------(I)

       p = 11 - 2q

2p + q = 10         --------------------(II)

Substitute p = 11 -2q in equation (II)

2(11 - 2q) + q =10

2*11 - 2q *2 + q = 10

22 - 4q + q = 10

  22 - 3q    = 10

         -3q   = 10 - 22

        -3q    = -12

              q = -12/-3

 q = 4

Plugin q = 4 in equation (I)

p + 2q = 11

p + 2*4  = 11

p + 8 = 11

      p = 11 - 8

      p = 3

There are 1,000 cans of cat food produced daily at a factory. in the meeting last week, the
BaLLatris [955]

Using the binomial distribution, it is found that the true statement related to the number of cans of cat food the company expects to be dented is given by:

B. The factory can expect to have an average of 50 cans dented in a day.

<h3>What is the binomial probability distribution?</h3>

It is the probability of exactly<u> x successes on n repeated trials, with p probability</u> of a success on each trial.

The expected value of the binomial distribution is:

E(X) = np

In this problem, we have that there are 1000 cans, each with a probability of 1/20 of being dented, hence:

n = 1000, p = 1/20 = 0.05.

The expected value is then given by:

E(X) = np = 1000 x 0.05 = 50.

Researching the problem on the internet, the correct option is given by:

B. The factory can expect to have an average of 50 cans dented in a day.
