Answer:
50% is not a possible population proportion who support candidate A.
Step-by-step explanation:
I will estimate 95% confidence interval to see if 50% a possible population proportion who support candidate A.
95% Confidence Interval can be calculated using
CI=p± where
- z is the corresponding statistic in 95% confidence level (1.96)
- p is the sample proportion who support candidate A (70% or 0.70)
- N is the sample size (250)
Then CI=0.70±≈ 0.70±0.06
That is 95% confidence interval is (64%, 76%). Since 50% is less than lower CI limit, 50% is not a possible population proportion who support candidate A.

Step-by-step explanation:
Answer:
The weigh of yellow potatoes that James bought is 8330 kilograms .
Step-by-step explanation:
Given as :
The weigh of red potatoes that James bought = 245 kilograms
The weigh of yellow potatoes that James bought = 34 times the weight of red potatoes
Let The weigh of yellow potatoes that James bought = x kg
Now, According to question
∵The weigh of yellow potatoes that James bought = 34 times the weight of red potatoes
i.e The weigh of yellow potatoes that James bought = 34 × The weigh of red potatoes that James bought
Or, x = 34 × 245 kg
Or, x = 8330 kg
So, The weigh of yellow potatoes that James bought = x = 8330 kg
Hence, The weigh of yellow potatoes that James bought is 8330 kilograms . Answer
X intercepts are where the y value is 0. So, set y=0 and solve
0=x^2-9x+18
0=(x-6)(x-3)
x=6,3
The x intercepts are (6,0) and (3,0)
if you want to check, try these (x, y) pairs in the original equation.
No because it does not pass the vertical line test,
meaning that a single vertical line could pass through multiple points on the graph.
