If you have a picture of the problem I can answer it so just send a pic of the math problem
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
At 0 weeks she had 75 L water remaining in the barrel (0, 75)
Since she used 5L each week, then at 15 weeks she had 0 L remaining (15, 0).
Answer: Top Right graph
V( cone ) = 21 cm³
note Vof cone = 
V of cylinder
V ( cone ) = × 63 = 21 cm³
