In the graph is shown: x-axis is the hours that student spend studying for the test and y-axis is a grade obtained by student. The best fit equation is y=3.75x+52.5.
If student spend 0 hours, then x=0 and y=3.75*0+52,5=52.5. It is that the student most likely earn <span>grade of 52.5 in the test. </span>
Answer:
x=![\frac{y2 }{9}](https://tex.z-dn.net/?f=%5Cfrac%7By2%20%7D%7B9%7D)
Step-by-step explanation:
2nd step: ![3\sqrt{x}=y](https://tex.z-dn.net/?f=3%5Csqrt%7Bx%7D%3Dy)
third step: ![\frac{3\sqrt{x} }{3} = \frac{y}{3}](https://tex.z-dn.net/?f=%5Cfrac%7B3%5Csqrt%7Bx%7D%20%7D%7B3%7D%20%3D%20%5Cfrac%7By%7D%7B3%7D)
fourth step: ![\sqrt{x} =\frac{y}{3}](https://tex.z-dn.net/?f=%5Csqrt%7Bx%7D%20%3D%5Cfrac%7By%7D%7B3%7D)
answer: x=![\frac{y2 }{9}](https://tex.z-dn.net/?f=%5Cfrac%7By2%20%7D%7B9%7D)
Answer:
Skewed
Step-by-step explanation:
Looking at the options;
- Bimodal has to do with 2 modes in a symmetrical Distribution. Thus is doesn't apply to the mean.
-bell shaped deals with the graphical depiction of a normal probability distribution, whereby the underlying standard deviations from the mean will create the curved bell shape. So it is not used for mean.
- symmetric deals mirror images of the distribution when a vertical line is drawn down the middle of the distribution.
-skewed shape tells us whether the mean is pulled to the tail and if it is more than or less than the median.
- uniform shape means same frequency for each class.
Pls give the question to expect that u get answers from others
Thank u
