Answer:

Step-by-step explanation:

What two number multiply to equal 6*(-12) and add to equal -1? That is -9 and +8.

6q^2-9q+8q-12

Now factor by grouping

(6q^2-9q)+(8q-12)\\3q(2q-3)+4(2q-3)\\(3q+4)(2q-3)

Seven is 3 less than twice the number m
aleksley [76]

Answer:

m=5

Step-by-step explanation:

Let the number be represented by m.

Then twice the number m is represented as 2* m or 2m.

3 less than twice the number m = 2m -3

As per the question this value is 7.

Representing this in equation format:

=> 2m-3 = 7

=> 2m = 7+3 = 10

=> m= 10/2 = 5

Hence the number m is given by 5.

Verification:

Twice the number = 2* 5 = 10

3 less than twice the number m = 10 -3 = 7

This is the same as 7 as per the requirement.

A shipment of ten smartphones contains five with cracked screens. If sold in a
Natalka [10]

Answer: 73.81%

Step-by-step explanation:

We know that 5 out of 10 have broken screens. So each smartphone has a probability of 50% of having a broken screen.

The probability that at most 3 of them have a broken screen is:

The probability that none has a broken screen p = 0

This is 0 because we are selling six of them and only 5 of them have the screen in good condition.

The probabilities are calculated as:

P = A*6!/(6 - n)!*n!

where n is the number of broken phones.

the probability is equal to

if we have only one broken screen:

for the broken phone, we have a 5/10 probability.

for the other 5 nice phones, the probabilities will be 5/9. 4/8. 3/7, 2/6 and 1/5 (the number changes because when we select one of the phones, the total number of phones decreases)

A = (5*5*4*3*2*1)/(10*9*8*7*6*5)

and is similar thinking for 2 and 3 broken phones.

Probability that one has a broken screen:

  P = ((5*4*3*2*1*5)/(10*9*8*7*6*5))*6 = 0.0238

Probability for two broken screen:

  P = (5*4*3*2*5*4)/(10*9*8*7*6*5))*6*5/2 = 0.2381

For 3 broken phones the probability is:

  P = ((5*4*3*5*4*3)/(10*9*8*7*6*5))*6*5*4/(2*3) = 0.4762

total probability = 0.0238 + 0.2381 + 0.4762 = 0.7381  

or 73.81% in percentage form.
