B 5
3 is half of 6
7 is half of 14
Answer:
x = 4
Step-by-step explanation:
(5x+131)° and (5x+19)° are supplementary. Therefore, (5x+19)° + (5x+131)° equals to 180°.
Knowing that, we can do the following:
- (5x+19) + (5x+131) = 180
- 5x + 19 + 5x + 131 = 180
- 10x + 140 = 180
- 10x = 40
- <em>x = 4</em>
Answer:
− 5 x − 16
Step-by-step explanation:
-2*x and -2*4= -2x+-8
-2x+3x= -5x
-8-8= -16
-5x-16
H0: μ = 8
H1: μ > 8
t = (8.25 - 8)/(0.8/sqrt(28)) = 1.654
t_table = 1.703
since t_calc < t_table, we accept H0, and conclude that the sample does not provide cnvincing evidence that the fertilizer had a positive impact on the weight of the corn ears at 0.05 level of significant.
Hey I'm probably too late but your answer would be 26-7i
Hope this helps :)
