The general formula for the margin of error would be:
z * √[p (1-p) ÷ n]
where:
z = values for selected confidence level
p = sample proportion
n = sample size
Since the confidence level is not given, we can only solve for the
<span>√[p (1-p) ÷ n] part.
</span>
p = 44/70
n = 70
√[44/70 (1 - (44/70) ÷ 70]
√[0.6286 (0.3714)] ÷ 70
√0.2335 ÷ 70
√0.0033357 = 0.05775 or 0.058 Choice B.
Answer:
y = -10
Step-by-step explanation:
(-7x+3y) - (-7x +10y) =-65 -(-135)
-7x + 3y + 7x -10y = 70
-7y = 70
y = -10
If te squre is inscribe in the cercle ten:The area of the circle is πR²
& the Area of te square is 2R², then the probability to land in the square :
2R²/πR²=2/π=0.6366 or 63.66%
Answer:
A: x‒axis: minutes in increments of 5; y-axis: temperature in increments of 1
Step-by-step explanation:
Let the x-axis represent the minutes
Let the y-axis represent the temperature
Now, from the values given us in minutes, we can see that the difference between the values are Increasing at constant rate of 5 minutes .
Thus, minutes increment on the x-axis is 5.
Now,for the y-axis, the increment is not constant as it fluctuates.
Thus, we cannot use 5 like we did for the x-axis. Rather, the most appropriate temperature increment to be used on this y-axis for ease of locating the points will be 1.
