Answer:
A) -13p^33q^-2 or -13p^3/q^2
B) 8x + 5y - 7
C) 15x^2 -23x + 4
Step-by-step explanation:
A) 169/(-13) = -13 p^4/p = p^3 q/q^3 = 1/q^2 which can be written as q^-2 and r/r is 1. So if you put this all together you get -13p^33q^-2 or -13p^3/q^2
B) 3(x +2y) + 5x - (y + 7)
3x + 6y + 5x - y - 7 distributive property
3x + 5x + 6y - y -7 combine like terms
8x + 5y - 7 Answer
C) (3x-4) (5x - 1) Foil multiply the first terms in each parenthesis. the outer terms, the inner terms and the last terms
(3x)(5x) + (3x)(-1) + (-4)(5x) + (-4)(-1)
15x^2 -3x - 20x + 4
15x^2 -23x + 4
Answer:
y - 0.32y = 0.68y
y + 0.32y = 1.32 y
Step-by-step explanation:
To simplify expressions, add/subtract using the coefficients of the terms.
y – 0.32y should be 1 - 0.32 = 0.68. This simplifies to 0.68y.
y + 0.32y should be 1 + 0.32 = 1.32. This simplifies to 1.32y.
Answer:
177 sq ft
Step-by-step explanation:
Big square = 169
4+4 = 8
13-8 = 5•1.6 = 8
Little square = 8
169+8 =177
Three adds to get 5 and also it multiplies to get 24

Answer:
P (A ║ B) = 1.98 %
Step-by-step explanation:
Bayes´ Theorem express
P (A ║ B) = P(A) * P( B ║ A) / P(B)
Now we identify
Event A person infected with a virus. Probability of being infected by a virus is P/A) 0.001
Event B the test was positive. Probability of test positive P(B) = 0,05
Probability of P ( B║ A) is the porbability of test positive given that is infected = 0.99
Then by subtitution in a general equation of the theorem we have
P (A ║ B) = 0.001*0.99/ 0.05
P (A ║ B) = 0.0198 P (A ║ B) = 1.98 %
