Answer:
between 78 and 102 texts and more than 78 text messages.
Step-by-step explanation:
the range of it is 102-178, so its between there, and its more than 78 as well if the range goes up to 102
The correct answers are:
-Less than 78
-More than 102
-Between 78 and 90
-Between 90 and 102
Quartiles show where 25% of the population lies. Since the bottom quartile is 78, we know 25% would be under. Since 102 is the upper quartile, 25% would be above.
We can also create further quartiles between the median and those quartiles.
Answer: X = 1/4 or X = -1
4x2+3x−1=0
(4x−1)(x+1)=0
4x−1=0 or x+1=0
4x=1 or x=-1
Now divide 4 from both sides
like this 4x/4=1/4
now cancel out two 4's so the answer will be x=1/4
Hope this helps!
Thanks!

As was the case in your previous question, this problem involves setting two ratios equal to each other. We call such an equation a proportion.
16 miles = x miles
(1/2) inch 2 3/4 inches
x = (11/4) * 16 = (11/4) * 2 * 16 = 88 miles
(1/2)
60mph=?hrs
50mph=?+1hr
?=6hrs
