Answer:
c = -18
Step-by-step explanation:
We need to distribute the -3 to each term within the parentheses. This essentially means finding the sum of the product of -3 with each of those inner terms:
-3 * c + (-3) * 14 + 3 = 15
-3c - 42 + 3 = 15
-3c = 15 + 42 - 3 = 54
c = 54/(-3) = -18
c = -18
Answer:
the second option 5 2/3
Step-by-step explanation:
since 0.3 with a line over it is equal to 2/3 and 3+2 is 5 our answer would be 5 2/3
By defferentiating the about using product rule
vdyu/dx +udvdx
dy/dx 4×^3 +6×^2-4× -4=o
If a random sample of 20 persons weighed 3,460, the sample mean x-bar would be 3460/20 = 173 pounds.
The z-score for 173 pounds is given by:

Referring to a standard normal distribution table, and using z = 0.66, we find:

Therefore

The answer is: 0.2546
