Answer:
3
Step-by-step explanation:
Let "a" represent Alondra's number. Then the math she performs on it is ...
2a-6 . . . .double my number and subtract 6
| 2a-6 | < 2 . . . . . the result is less than 2 units from zero
This absolute value expression can be "unfolded" to two of them ...
-2 < 2a -6 < 2
Dividing by 2 gives ...
-1 < a -3 < 1
Adding 3, we get ...
2 < a < 4
The only whole number in this range is ...
a = 3
Alondra is thinking of the number 3.
To figure out how many 8ths are in 48, you do 48/8=6
So 1/8 of 48 is 6
So to figure out 5/8 do
6*5=30
Hopefully this helps :D
Answer:
Reliability
Step-by-step explanation:
Dylan took the Whaddayanno IQ Test today, and his IQ score was 130. Last week, his IQ score on the same test was 70. The Whaddayanno IQ Test appears to lack reliability.
Reliability can be defined as the extent to which an experiment or test provides the same result on repeated trials.
The huge difference in Dylan's IQ test scores in a short period of time suggests that the Whaddayanno IQ test is not reliable.
The answer answer is x=5 (y-3)
