Answer:
p(X> 6 ) = 0.01132 + 0.01672 = 0.0280
Step-by-step explanation:
The probability that the US woman would have more than six children is equal to the probability that she would have children that are equal to 7 or that she would that she would have children equal to 8 or more as shown on the table in the question
Now representing this mathematically we have
p(X > 6) = p(x =7 ) + p(x = 8 or more)
From the table the p(x = 7 )
And the p(x= 8 or more )
Hence p(X> 6 ) = 0.01132 + 0.01672 = 0.0280

Answer:
a. $ 381.969,
b. $ 369.171,
c. Kings Savings
d. Reliability.
Step-by-step explanation:
∵ Amount formula in compound interest,
And, amount formula in continuously,
,
Where,
P = principal amount,
r = rate per periods,
t = number of periods,
a. In State bank,
P = $ 9000, r = 2.1% = 0.021, t = 2 years,
Also, interest earned compound annually,
Thus, amount,
So, interest earned = A - P = 9381.969 - 9000 = $ 381.969,
b. In Kings Savings,
P = $ 9000, r = 2.01% = 0.0201, t = 2 years,
Also, interest earned compound continuously,
Thus, amount,
So, interest earned = A - P = 9369.171 - 9000 = $ 369.171,
c. ∵ 369.171 > 381.969
Thus, King saving pays higher interest.
d. Since, the other factors might affect Whitney's choice besides interest would be reliability.

Because he needs less than (note that he didn't say he needs no more than) 6 pounds, first inequality is C) x+y<6
Now in inequalities that have 7 and 5 in them, 7 represents the cost of first ingredient and 5 the cost of second ingredient. If we multiply each of that number with quantity of that ingredient and sum both up we get the price of the mixture.
Because he says that he wants that mixture costs no more than 30 that means that it costs less than 30 but 30 can be the answer as well.
The last answer is E) 7x + 5y
