The correct inequality is letter a.

Okay. I think you mean how many text messages must you send, until plan B is cheaper than plan A. Plan A is the one with the $30 fixed amount and plan B is the one with the $50 dollar fixed amount. The key words "cheaper than" means that our sign will be less than, not less than or equal to. Therefore, C is out.  We are looking for plan B ($50 fixed amount) to be less than. B and D are out, because those are greater than symbols toward plan B. A is the only one that shows the proper answer, and when you solve it right, you get m > 375. You would have to send 376 messages in order for plan B to be cheaper. The answer is A.

On a trip, a motorist drove 150 miles in the morning and 50 miles in the afternoon. His average rate in the morning was twice hi
AfilCa [17]

A motorist drove 150 miles in the morning and;

50 miles in the afternoon

His average rate in the morning was twice his average rate in the afternoon

He spent 5hrs driving

Let the times spent driving in the morning be x

Average speed = Distance ÷ time

\frac{150}{x} = 2(\frac{50}{5 - x})

Cross multiplying gives;

750 - 150x = 100x

250x = 750 , x =3

Average speed in the morning is 150/3 = 50miles/hr

Average speed in the afternoon = 50/(5-3) = 25miles/hr

Marina86 [1]

The Mean will decrease while the Median and the Mode will remain with the same amount.

For Central Measures, we have Median, Mode and  Mean. They try to describe the whole distribution by one value, in the center of it.

For this question, let's pick some examples from the Old Faithful, WY Station to the National Oceanic and Atmospheric Administration from 2015, January

1st Case Scenario:

For 7 days of precipitation, (Snow, ice pellets, etc. rain) in inches:

19 19 19 24 23 23 23 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0

Mean = 5

Median=0 (the sum of the 15th+16th position over 2)

Mode=0 (Most common observations)

2nd Case Scenario

For 3 days of precipitation, (Snow, ice pellets, etc. rain) in inches:

0 0 0 24 0 0 23 0 19 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0

Mean = 2.2

Median =0

Mode=0

Mary is half of her sister's age. The sum of their<br> ages is 18. How old is her sister?
Ksivusya [100]

Answer:

Mary's sister is 12 years old.

Step-by-step explanation:

If Mary is half of her sister's age, her sister is 2 times her age.

Represent M as Mary's age...

M+2m=18

3m=18

3m/3=18/3

m=6

But because Mary is a half of her sister's age...

6*2=12
