Answer:
(a) The survival rate for drug A is 87,75%.
(b) The survival rate for drug B is 81,76%.
Step-by-step explanation:
To get the survival rate of each drug you have to divide the number of women alive between the total number of women that use the drug.
For drug A= women alive that use drug A/ total number of women that use the drug A= 473/539
For drug A=0,8775= 87,75%
For drug B= women alive that use drug B/ total number of women that use the drug B
For drug B== 426/521= 0,8176 = 81,76%
Hello from MrBillDoesMath!
Answer:
Choice B.
Discussion:
From the first step
324 x^6 y^ 8 =
2^2 * 3^4 * x^2 * x^4* y^8
so the fourth root of this is
2 ^(2/4)* 3^(4/4) x^(2/4)* x^(4/4)*y^(8/4) =
2^ (1/2) * 3^1 * x^(1/2) * x^(1)* y^ (2) =
(2x)^(1/2) * 3 * x * y^2 =
3 * x * y^2 * sqrt(2x) =
3 * x * y^2 * ( (2x)^2) ^ (1/4)) =
3 * x * y^2 * (4x^2) ^ (1/4)
which is choice B
Thank you,

Answer:
This statement is "TRUE".
Step-by-step explanation:
Every elementary row operation is reversible. You can get the reverse answer by multiplying by a constant or by multiplying by its inverse. You can add one row to another row and subtract row 1 from row 2 to get it back.
