Answer:
A. y=1-2x
Step-by-step explanation:
-1 =1-2(1)
-1= 1-2
-1=-1
-3=1-2(2)
-3=1-4
-3=-3
-5=1-2(3)
-5=1-6
-5=-5
-7=1-2(4)
-7=1-8
-7=-7
10x^4y^4+2x^6-15y^6-3x^2y^2
290-10=280
280 is one standard deviation below.
All that are above mean is 50%.
One standard deviation below is 34%.
50%+34%=84% all of these bags weigh more than 280 g.
So,
100%-84%=16% should be bags that are less than 280 g.
Answer is b) 16 %.
Answer:
An apple costs $0.45 and a banana costs $0.66.
Step-by-step explanation:
This question is solved by a system of equations.
I am going to say that:
An apple costs x.
A banana costs y.
2 apple and 5 bananas cost 4.20 dollars
This means that:

So


3 apples and 4 bananas cost 4.
This means that:

Since 





Then:

An apple costs $0.45 and a banana costs $0.66.
<span>Based on the data in the two-way table, the probability of being older than 25 years and having a hemoglobin level above 11 is
(154-69)/(429-139)
=85/290
=0.2931~0.29
Answer: A. 0.29
