The function would do 3 things
1. flip horizontally, because of the negative applied to the slope
2. widen, because of a fractional slope between -1 and 0 (-2/7 makes the rise shorter than the run, so the function widens by going 7 units out for every 2 units down)
3. shift down 7 units, because the initial y-intercept would be changed from, say, 8 to 1. this would bring the graph downwards by 7 units
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.
Answer:
O4) x = y
Step-by-step explanation:
I took this before
Answer:
1. P = 81
2. P = 54
3. P = 54
4. P =5
Step-by-step explanation:
By looking at the table:
1. Have diploma,
P = 54 + 27
= 81
2. Have diploma and experience,
P = 54
3. Have experience or have diploma,
P = 54
4.Have no diploma or have experience,
P = 5
The answer is 4x10^14 because there are 14 zeros in front of the four thus you do 4x10^(number of zeros) and thus you get 4x10^14
