Answer:
- <u>The horizontal move of the shape was 10 units to the right,</u>
Explanation:
The problem requires that you find <u>how far the shape was moved horizontally</u>.
To find the horizontal translation of the shape, you must subtract the x-coordinate of the original corner (the pre-image) from the x-coordinate of the final corner (the image)
Final corner (image):
- Coordinates: (6,8)
- x-coordinate: 6
Original corner (preimage):
- Coordinate: (-4,5)
- x-coordinate: -4
Translation:
- Difference = 6 - (-4), which is what Erin wrote
Thus, the horizontal move of the shape was 10 units to the right.
Answer:
Z SCORE FOR 1870 = 1.26
Z SCORE FOR 1200 = -0.89
Z SCORE FOR 2180 = 2.25
Z SCORE FOR 1380 = -0.315
Step-by-step explanation:
given data:
test score
= 1478
standard deviation
= 311
z score can be calculated by using below relation
![Z = \frac{X-\mu}{\sigma}](https://tex.z-dn.net/?f=Z%20%3D%20%5Cfrac%7BX-%5Cmu%7D%7B%5Csigma%7D)
1) Z SCORE FOR 1870
![= \frac{1870-1478}{311}](https://tex.z-dn.net/?f=%3D%20%5Cfrac%7B1870-1478%7D%7B311%7D)
= 1.26
2) Z SCORE FOR 1200
![= \frac{1200-1478}{311}](https://tex.z-dn.net/?f=%3D%20%5Cfrac%7B1200-1478%7D%7B311%7D)
= -0.89
3) Z SCORE FOR 2180
![= \frac{2180-1478}{311}](https://tex.z-dn.net/?f=%3D%20%5Cfrac%7B2180-1478%7D%7B311%7D)
= 2.25
4) Z SCORE FOR 1380
![= \frac{1380-1478}{311}](https://tex.z-dn.net/?f=%3D%20%5Cfrac%7B1380-1478%7D%7B311%7D)
= -0.315
There are no unusual z value.

Answer:
- y = 100,000(1 + 0.15)^t
- y = 1200(1 -0.06)^t
- y = 49.50(1 -0.07)^t
- y = 135(1 +0.05)^t
- value of $200 decreases (decays) by 25% each year
Step-by-step explanation:
It should be no stretch to understand that "increases" means the function is a growth function (+ sign), and "decreases" means the function is a decay function (- sign).
The multiplier in front (a) is the initial value — the value when t=0.
Multiply 2 and 8.
2•8=16
Add 16 and 3.
16+3=19
