1.
-5x - 6 = 1
-5x = 7
x = 7/-5
2.
12d + 2 - 3d = 5
9d + 2 = 5
9d = 3
d = 1/3
3.
0.25x + 7 = 12
0.25x = 5
x = 20
4.
7.4p - 9.2p = -2.6 + 5.3
-1.8p = 2.7
p = -1.5
Hope this helps! :)
Answer: Domain of f(x) = ⌈2x⌉ – 1 is {x| x is a real number}.
Answer:
x/25 = 100/500
Step-by-step explanation:
so, to find the MA, you'd do x/25 since you're trying to find out the discount for Phone Plan A. 25 is the 25% of the Phone Plan A
2 * 2 * 2 * 2 * 2
4 * 2 * 2 * 2
8 * 2 * 2

The solution is 32
Answer:
D) 89.6 %
Average or mean of the given data = 89.6 %
Step-by-step explanation:
<em><u>Step(i):-</u></em>
Given data
X : 82 100 84
P(X=x) : 0.40 0.40 0.20
<u><em>Step(ii)</em></u>
Let 'X' be the discrete distribution
Mean of the discrete distribution = ∑ x P( x=x)
= 82 ×0.40 +100 ×0.40 +84 ×0.20
= 89.6
<u><em>Final answer:-</em></u>
Average of the given data = 89.6 %
