Mean: The sequence adds up to 385 divided by 55 numbers in the set to get the mean of 7.
Median: The middle value of the sequence in order is 7.
Mode: 10 (It’s obvious because there’s ten 10’s.)
I am pretty sure the answer is B
$83.4
because 30%=0.3
0.3•$278= $83.4
Answer:92
Step-by-step explanation:
Answer:
a = 6
x = 5/4
x = -1
Step-by-step explanation:
1.
Distribute the negative sign.
- * 7 = -7
- * -a = a
a - 7 + a = 5
2a - 7 = 5
•Add seven to both sides.
2a = 12
a = 6
2.
Distribute the negative sign as we did for problem one.
-2 -x + 7
-x + 5 = 3x
Add x to both sides
4x = 5
x = 5/4
3.
As for the previous problems distribute the negative, remember this step is always imperative!
-3x -1 + 4 = 6
-3x + 3 = 6
Subtract 3 in both sides
-3x = 3
x = -1
Thanks!
