Answer:
-14 *3 and -14 + 3
Step-by-step explanation:
-46=3x+7x
-46=10x
X= 10/(-46)
X=-5/23
Therefore, the equation only has one solution
Answer:
a) 7^10
b) 7^4
c) 7^21
Step-by-step explanation:

This is the concept of rate. The average cost of gasoline per mile will be:
Average cost=[amount]/[distance]
=1512/8061
=0.188 dollars per mile
=0.188 $/M
Note: The values in the table are not correct because the sum of the probability of all events is not equal to one. The should be 0.13 and 0.33 instead of 0.113 and 0.133 respectively.
Given:
The probability distribution for a random variable x is given in the table.
x : -5 -3 -2 0 2 3
P(x) : 0.17 0.13 0.33 0.16 0.11 0.10
To find:
The probability of -2.
Solution:
From the given probability distribution for a random variable x, it is clear that the value of the probability is 0.33 corresponding to -2.

Therefore, the probability of -2 is 0.33.
