You can evaluate the functions separately, then add results:
.. f(3) = 2*3 +21 = 27
.. g(3) = 3 -24 = -21
(f +g)(3) = f(3) +g(3) = 27 -21 = 6
Or, you can find the combined function and evaluate that for x=3.
.. (f +g)(x) = f(x) +g(x)
.. = (2x +21) +(x -24)
.. = 3x -3
The
.. (f +g)(3) = 3*3 -3 = 6
Either way, the best choice is C) 6.
Answer:
DISTRIBUTIVE PROPERTY BRO...
Step-by-step explanation:
The answer is 6.27. Hope this helps.
Solution :
The sample proportion 
= 0.024
<u>90% confidence interval </u>
The standard deviation = 
= 
= 0.00484
z = 1.645 for 90% CI
Upper band = 0.024 + (0.00484 x 1.645 ) = 0.03196
Lower band = 0.024 - (0.00484 x 1.645 ) = 0.01603
Therefore, the 90% CI is (0.016, 0.032)
<u />
<u>99% confidence interval </u>
z = 2.576 for 99% CI
Upper band = 0.024 + (2.576 x 0.00484 ) = 0.0365
Lower band = 0.024 - (2.576 x 0.00484 ) = -0.0115
Therefore, the 99% CI is (0.0115, 0.0365)
Answer:
A) 5 and B) 5
Step-by-step explanation:
A) 5x-12=13
+12 +12 (add 12 to the 13)
5x=25
(then divide 25 by 5 which is 5 so the answer is 5)
B) 8(x+3)=64 (first use distributive property)
8x+24=64
-24 -24 (then subtract 24 to 64 which is 40)
8x=40
(then divide 40 by 8 which is 5 so that is it!)
I believe this is correct, I hope this helps :D
