Y-y1=a(x-x1)
a=(y2-y1)/(x2-x1)
a= (6-(-2))/(7-1)
a=8/6
a=4/3
y-6=4/3(x-7)
y-6=4/3x-28/3
y=4/3x-28/3+6
y=4/3x-10/3 >>ef

What are the chances your flight will leave on time? Below are a histogram and summary statistics for the percentage of flights
Jet001 [13]

Answer:

80.0456<\bar x<81.1210

Step-by-step explanation:

-Given the mean, \bar y=80.5833 and s=2.77369, the confidence interval can be calculated using the formula:

\bar x\pm z\times \frac{\sigma}{\sqrt{n}}

#We substitute our values in the formula to solve for CI:

=\bar x\pm z\times \frac{\sigma}{\sqrt{n}}\\\\=\bar y\pm z_{0.05}\times \frac{s}{\sqrt{72}}\\\\=80.5833\pm 1.645\times \frac{2.77369}{\sqrt{72}}\\\\=80.5833\pm0.5377\\\\=[80.0456,81.1210]

Hence, the confidence interval lies between 80.0456 and 81.1210

Hey guys my last question please answer :) peace and love guys
Vadim26 [7]

Looking at the problem statement, this question states for us to determine the range of the function that is provided in a graph is.  Let us first determine what range is.

  • Range ⇒ Range is what y-values can be used in the function that is graphed.  For example, if a line just goes up and down all the way to negative and positive infinity, then the range would be negative infinity to positive infinity as it includes all of the y-values in it's solutions.

Now moving back to our problem, we can see that we have a vertex at (2, -5) and that the lowest y-values is at y = -5.  Therefore the y-values would be anything greater than or equal to -5 and less than infinity because the lines go forever up in the positive-y-direction.

Therefore, the option that would best match the description that we provided would be option B, -5 ≤ y < ∞.
