Answer:
0.0618.
Step-by-step explanation:
14-18= -4
-4/2.6= -1.538
Use the Z-table to find the proportion that aligns with 1.54 (round up because of the 0.008)
The intersection between 1.5 and 0.04 will be 0.0618.
Answer:
y = (1/4)x - 3
Step-by-step explanation:
The slope-intercept form is y = mx + b. Here we are told that the line passes through (-8, -5) and that its slope is 1/4 (is that correct?).
Substituting -5 for y, -8 for x and 1/4 for m, we get an equation for the y-intercept, b:
-5 = (1/4)(-8) + b, or
-5 = -2 + b, so b = -3, and the desired equation is
y = (1/4)x - 3

Step-by-step explanation:
An arithmetic sequence that is described by the explicit formula ...
![a_n=a_1+(n-1)d](https://tex.z-dn.net/?f=a_n%3Da_1%2B%28n-1%29d)
can also be described by the recursive formula ...
![\left \{\begin{array}{l}a_1=\text{(first term)}&a_n=a_{n-1}+d&\end{array}\right.](https://tex.z-dn.net/?f=%5Cleft%20%5C%7B%5Cbegin%7Barray%7D%7Bl%7Da_1%3D%5Ctext%7B%28first%20term%29%7D%26a_n%3Da_%7Bn-1%7D%2Bd%26%5Cend%7Barray%7D%5Cright.)
Matching parts of the formulas, we see that a1 = 4, d = -7. Putting these values into the explicit formula gives ...
![a_n=4+(n-1)(-7)](https://tex.z-dn.net/?f=a_n%3D4%2B%28n-1%29%28-7%29)
