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.

ruslelena [56]

Answer:

Rate of Return is 14.8%

Step-by-step explanation:

We know that 20 shares of Stock are purchased for $30 per share.

This gives us a total value of: 20 × 30 = $600.

Now, the shares are sold for $710 with a commission sale of $6. This means the final money going to the seller is; 710 – 6 = $704.

Thus, the rate of return percentage is = (704 – 600)/704) × 100% = 14.7727%

To the nearest tenth gives us 14.8%

The probability of multiple events happening is found by multiplying the probabilities of each event together.

P_{d+even\ number}=P_{d}*P_{even}\\\\P_{d}=\frac{number\ of\ events}{total\ number\ of\ events}=\frac{(d)}{a,\ b,\ c,\ d,\ e)}=\frac{1}{5}\\\\P_{even}=\frac{number\ of\ events}{total\ number\ of\ events}=\frac{(2,\ 4,\ 6)}{(1,\ 2,\ 3,\ 4,\ 5,\ 6)}=\frac{3}{6}=\frac{1}{2}\\\\\frac{1}{5}*\frac{1}{2}=\boxed{\frac{1}{10}}

So yes, 1/10 is the answer :)
