C because you have to round and it would be C
Answer:
That would be 175% since in your question or the way you phrased it atleast, 100%=4, so 1 would be 25%, 25% times 3=75 so 175% =4+3=7

- B. 0.997359
Step-by-step explanation:
1. The policy rates in the table are for $25000 of insurance. Lydia wants $100,000 of insurance, which is 4 times the amount quoted in the table. Hence her premium will be 4 times the quoted premium. Her spot in the table is in the age 24–30 row and the Female Non-Smoker column. Lydia's premium will be 4×$3.50, or $14 per month.
She wants 2 times the amount quoted in the table ($50,000) of insurance for her spouse, so the premium will be 2 times that quoted in the table. His spot in the table is in the age Under 24 row and the Male Smoker column. The premium for his insurance will be 2×$4.50, or $9 per month.
The total of the two premiums will be $14 = 9 = $23 per month.
___
2. The probability of living another year is the complement of the probability of dying. For a 35–44 year-old male, the probability of dying is 264.1/100,000, about 2.641×10^-3. The complement of that is ...
1 - 0.002641 = 0.997359

Answer:
405 cm²/s
Step-by-step explanation:
The dimensions are increasing at the rate of 3 cm/s, so the dimensions in cm can be described as a function of time by ...
3 + 3t
and
6 + 3t
Then the area is the product of these, or ...
A = (3 +3t)(6 +3t)
A = 9t² +27t +18
and the rate of change of area is given by its derivative with respect to t:
A' = 18t +27
When t=21, the value of this is ...
A'(21) = 18·21 +27 = 405 . . . . cm²/s
