Answer:
A1-60x+460
A2-50x+530
B-60x7+460
50x7+530
Step-by-step explanation:
A1 and A2-since x is equivalent to number of months we multiply the number of months then add it to the original cost to get how much total you get in the account.
B-you add 50 to 530 and 60 to 460 until they equal the same amount in this case its 7 times.
Answer:
a = 3
Step-by-step explanation:
-12x³+14x²+6x = -2x(ax+1)(2x-3)
<em>Divide both sides by -2x(2x-3)</em>
ax+1=3x+1
<em>Subtract 1 from both sides</em>
ax=3x
<em>Divide both sides by x</em>
a=3
Answer:
P(X = 2) = 0.27894
Step-by-step explanation:
Given:
- The probability that no vision correction is required p = 0.23
- No. adults are randomly selected n = 6
Find:
- P ( Exactly 2 dont require vision correction)
Solution:
- We will declare a random variable X is the umber of adults out of 6 that do not require vision correction. X follows a Binomial distribution:
X~ B ( 6 , 0.23 )
- The probability required is P ( X = 2 )
- Using the pmf of binomial distribution we have:
P(X = 2) = 6C2 * (0.23)^2 * (0.77)^4
P(X = 2) = 15 * 0.0529 * 0.35153041
P(X = 2) = 0.27894
