5-(8v+5) = -4(1+3v)
5-8v-5 = -4 - 12v
-8v = -4 - 12v
4v = -4
v = -1
Answer:
y=-1

Answer:
a P(x) = Q(x)
b. R(x) = Q(x)
c. R(x) = P(x)
d. Yes
Step-by-step explanation:
This is a statement of logical connectives.
a P(x) = Q(x)
b. R(x) = Q(x)
c. R(x) = P(x)
d. Yes, (c) follows from (a) and (b)
Reasoning:
(c) is equivalent to ∀x ¬ P(x) ∨ Q(x)
Proof:
Follow the tautology (X→Υ) Ξ(¬x∨Υ)
This gives X: R(x) ∧ ¬ P(X)
Answer:
the average distance from the mean is:
$ 7.2
step-by-step explanation:
we are given data points as:
$7, $20 , $9 , $35 , $12 , $15 , $7 , $10 , $20 , $25 , $7 , $20 , $9 , $35 , $12 , $15 , $7 , $10 , $20 , $25
the mean of the data set is:
now we are asked to find the average distance from the mean or mad of the data.
the absolute difference of each data point from mean is calculated as follows:
|7-16|=9
|20-16|=4
|9-16|=7
|35-16|=19
|12-16|=4
|15-16|=1
|7-16|=9
|10-16|=6
|20-16|=4
|25-16|=9
|7-16|=9
|20-16|=4
|9-16|=7
|35-16|=19
|12-16|=4
|15-16|=1
|7-16|=9
|10-16|=6
|20-16|=4
|25-16|=9
the answer is: $ 7.2
