For this case, the first thing you should keep in mind is:
The solution of the inequation system is given by the shaded region.
Each inequality is met to the right of each graph.
We have then:
For inequation 1:
(2, 6)
(1, -3)
(-2, 5)
For inequation 2:
(2, 6)
(-1,-1)
(-3. 4)
(1, -3)
For the system:
(2, 6)
(1, -3)
Answer:
A. Figure A
Step-by-step explanation:
The protractor on the top left has an arrow halfway inbetween 50° and 60, making the angle 55°.
Therefore, the answer is Figure A.
3:5 is the ratio of cups of rice to cups of water.
Add 0.5 to 0.5 and 3.7 to make X by itself
3.7 + 0.5 is 4.2
4.2 / 2 (because you get X by itself
X = 2.1
Let X represent a random variable representing the birth weights of babies, and let x be the required cut-off, then
P(X < x) = 0.02
P(z < (x - 3419)/494) = 0.02
1 - P(z < (3419 - x)/494) = 0.02
P(z < (3419 - x)/494) = 1 - 0.02 = 0.98
(3419 - x)/469 = 2.04
3419 - x = 956.76
x = 3419 - 956.76 = 2462.24
Therefore, the weight to be used as cut-off is 2462.24 g
