Answer:8 planes are shown in the figure
Step-by-step explanation:
Answer:
confidence interval:
This tells us the degree of certainty or uncertainty that is existent in a sampling method. It gives us a range of values, telling us we are fairly sure that our true value or parameter lies within the range.
Degree of confidence:
This tells us that the confidence interval has captured the true/exact population parameter.
If we have 95% degree of confidence, we are 95% sure that that the exact/true parameter are in the confidence interval
Answer:

Step-by-step explanation:
step 1
Find the slope of the line
The formula to calculate the slope between two points is equal to

we have the points
(2,24) and (6,16)
substitute in the formula



step 2
Find the equation of the line in slope intercept form

we have

----> the k-intercept is the point (0,28) see the graph
substitute

<span>-2b^2 -3b+14=0
(-2b - 7)(b - 2) = 0

Answer:
4 hours and 10 min
Step-by-step explanation:
For this equation we will do ratios:

250 min =
4 hours and 10 min
4(60) = 240
240 + 10 = 250 minutes
