Answer:
= 1700 :)
Step-by-step explanation:
-multiply all the sides,
-add them,
- then double the answer (or times it by 2):
1) 30 times 20 = 600
30 times 5= 150
20 times 5 =100
2) Add them:
600+150+100 = 850
then times 850 by 2
850 times 2 = 1700

It’s C
you can plot each equation on a graphing website like geogebra or desmos !
Answer: First Option is correct.
Step-by-step explanation:
Since we have given that
Mean 
= 70 inches
Standard deviation 
= 3 inches
Average basket ball player 
= 79 inches
Since it is normally distributed assume with 5% significance .
So, it becomes,
At 0.05 level of significance , 0.0013 = 0.13% of the adult male population is taller than the average basketball player .
Hence, First Option is correct.
Answer:
a.2,400-1700=
b. 700: the hot air balloon decreased height by 700 feet
We can see that the lines intersect at (-5,3) on the graph, so that eliminates choices B and D. Both A and C say that the first line is y=x+8, which is true. A says that the second line is y+x=-2, and after isolating y, we get y=-x+2, which seems correct. Do the same for C, and you will find that it says the other equation is y=x-2, which is not true because it must have a negative slope. So your answer will be choice A.
