Answer:
H0: p ≤ 0.50
Ha: p > 0.50
Step-by-step explanation:
The null hypothesis (H0) tries to show that no significant variation exists between variables or that a single variable is no different than its mean. While an alternative Hypothesis (Ha) attempt to prove that a new theory is true rather than the old one. That a variable is significantly different from the mean.
For the case above;
Let p represent the proportion of households in the city that gave a charitable donation in the past year
The null hypothesis is that the proportion of households in the city that gave a charitable donation in the past year is not more that 0.50
H0: p ≤ 0.50
The alternative hypothesis is that the proportion of households in the city that gave a charitable donation in the past year is more that 0.50
Ha: p > 0.50

Answer:
Step-by-step explanation:
If B lies between A and C on a line segment, then ...
AB +BC = AC
(2x -17) +(x +1) = 14
3x = 30 . . . . . . . . . . . . . add 16, collect terms
x = 10 . . . . . . . . . . . divide by 3
AB = 2(10)-17 = 3
BC = 10+1 = 11
