Answer:
0.8
Step-by-step explanation:
Find the mean of the list:
(0.2, 0.21, 0.17, 3.22, 0.2)
The mean of a list of numbers is given by:
(sum of elements)/(number of elements)
(sum of elements) = 0.2 + 0.21 + 0.17 + 3.22 + 0.2:
(0.2 + 0.21 + 0.17 + 3.22 + 0.2)/(number of elements)
Counting, we see that the list has 5 elements:
(0.2 + 0.21 + 0.17 + 3.22 + 0.2)/5
0.2 + 0.21 + 0.17 + 3.22 + 0.2 = 4:
4/5
4/5 = 0.8:
Answer: 0.8
The sum of 14 and 16 is 30.30 times 4 is 120.
<span>(<span>14+16</span>)</span><span>(4)
</span><span>=<span><span>(30)</span><span>(4)</span></span></span><span>=
<span>120</span></span>
Answer: 6
Step-by-step explanation:
(24 - x)/2 = 9
multiply both sides by 2
24 - x = 18
subtract both sides by 24
-x = -6
multiply both sides by negative 1
x = 6
When the sign is ≤ or ≥ (less/greater than or equal to), the dot is filled in.
When the sign is < or >, the dot is not filled in and looks like this o
To find out which number line represents the solution set, simplify the inequality and isolate x
Multiply -2 on both sides to get rid of -1/2
x ≤ -8 (The sign flips when you multiply/divide a negative number on both sides of the inequality)
so you get x is greater than or equal to -8, so you have a filled in circle on -8, and the arrow should be going to the right since x is greater than -8
