Mr Zuro finds the mean height of all 13 students in his statistics class to be 68.0inches. Danielle walks in late. Danielle is 7
sergejj [24]

Answer:

68.3 inches

Step-by-step explanation:

Let the sum of the original 13 students heights be S, so the average of their heights are S/13.

We are given that average height of the original 13 students heights is 68 inches, so S/13 = 68 -> S = 68*13 = 884 inches.

The average of the heights of all 14 students is the sum of all 14 students (S + Danielle’s height) divided by 14. We are given that Danielle’s height is 72.2 inches, so the mean height of all 14 students is:

(S+72.2)/14 = (884+72.2)/14 = 68.3 inches

I hope this helps! :)

Describe the transformation that takes f(x) = |x| to g(x) = −| x +4 | − 1
Katen [24]

Answer:

Horizontal translation → Reflection about x-axis → Vertical Translation

Step-by-step explanation:

We are given the function f(x) = |x|.

This function is transformed to the new function given by g(x) = - |x+4| - 1.

So, we see that,

1. Translation of 4 units to the left is applied, which changes f(x) = |x| to |x+4|.

2. Reflection about x-axis is applied, which changes |x+4| to - |x+4|.

3. Finally, translation of 1 unit downward is applied, which changes - |x+4| to g(x) = - |x+4| -1.

Hence, the sequence of transformation applied to obtain g(x) from f(x) is Horizontal translation → Reflection about x-axis → Vertical Translation.
