Area = Length * Width
18 = 3 * x
You could also do 18 ÷ 3 = x
What is x?
2x + y - z = -3 .....multiply by 2
5x - 2y + 2z = 24
-----------------
4x + 2y - 2z = -6 (result of multiplying by 2)
5x - 2y + 2z = 24
----------------add
9x = 18
x = 18/9
x = 2
3x - z = 5
3(2) - z = 5
6 - z = 5
6 - 5 = z
1 = z
2x + y - z = -3
2(2) + y - 1 = -3
4 + y - 1 = -3
y + 3 = -3
y = -3 - 3
y = -6
solution is : (2.-6,1)
Hello!
When you look at the table you see that V(x) is increasing so we know that the answer has the word grow in it.
Next you can substitute one of the x values in one of the equations to see if you get the v(x) value
Next you can do 4(0.65)^1 to see if you get 5.4
When you put it into a calculator you get 2.6
Now you can put 1 in for x for the other equation
4(1.35)^1 to see if you get 5.4
This does give us 5.4
So the answer is C, V(x) = 4(1.35)^x, and it grows.
Hope this helps!
Answer:
Step-by-step explanation:
Given that it came as a big surprise when Appleâs touch screen iPhone 4, considered by many to be the best smartphone ever, was found to have a problem (The New York Times, June 24, 2010). Users complained of weak reception, and sometimes even dropped calls, when they cradled the phone in their hands in a particular way. A quick survey at a local store found that 2% of iPhone 4 users experienced this reception problem
Here all iphone users are the subject matter of interest.
Hence the population is all Iphone 4 users.
2% is the characteristic of the sample of survey done hence this is a sample statistic
1) a) true
2) b) Sample statistic
