Answer:
x= 3. y = 3
Step-by-step explanation:
-3x + 7y = 12. #1
x - 2y = -3. #2
Multiply Eqtn #2 by 3 and add the two together:
-3x + 7y = 12
3x - 6y = -9
or. y = 3
Plug this value into Eqtn #2 and you'll get
x = 3
2x - 4y = 8
2x = 8 + 4y
x = 8/2 + 4/2 y
x = 4 + 2y
Answer:
(a) Having a smashed corner need to now not depend on whether or not the carton had a puncture or not,
so these occasions have to be independent.
One manner to check it the usage of the given probabilities:
If P(A)P(B) = P(A and B), then the events are independent.
Here we have : (0.05)(0.08) which is 0.004, that is P(A and B), so the events are independent.
(b) P(A or B) = P(A)+P(B)-P(A and B) = 0.05 + 0.08 – 0.004 = 0.126

(3x^5 + 8x^3) - (7x^2 - 6x^3) = 3x^5 + 8x^3 - 7x^2 + 6x^3 = 3x^5 + 14x^3 - 7x^2
Quantity of Hgb in 100 ml of blood = 14.5 grams
Now we will use unitary method to find quantity of Hgb in 1 ml of blood.
Quantity of Hgb in 1 ml of blood = 14.5 /100 = 0.145 grams.
Now we have to find quantity of Hgb in 5.5 quarts of blood.
Let us first convert 5.5 quarts into ml.
1 quart = 946 ml
So 5.5 quarts = 5203 ml
So quantity of Hgb in 5203 ml of blood = 0.145 * 5203 = 754.435 grams
Answer: The patient has 754.435 grams of Hgb in his body.
