404 is the answer. if you add them all together
We first take the sum of the squares of the differences between the sample data and the limit 45 mph: 1^2 + 11^2 + 0^2 + (-1)^2 + 0^2 + 16^2 + 10^2 + 8^2 + (-6)^2 = 579. Dividing by 8 (# of cars less 1) gives 72.375, which is the variance. Taking the square root gives the SD of 8.5.
The measure of central tendency most affected by the 10th value of 1.5 mph is the mean. The median and mode are relatively unaffected since both involve the frequency of terms, and having a tenth term that is far below (like 1.5) will not affect it much as compared to if it was near the rest of the values (like anything below 39).
The new SD including the tenth car involves adding the deviation of (-43.5)^2 to the sum of 579, which gives 2471.25. Dividing by 9 (there are now 10 data points) and taking the square root gives the new SD of 16.6.
The slope-point form:
We have two points (4, 5) and (-3, -1). Substitute:
For point (4, 5):
For point (-3, -1):
Answer:
Daisha started her homework at 4:25
Step-by-step explanation:
I first take off the 5 minutes after 5:00 (i will add it back later)
Then i subtract 40 from 60 (60 minutes = 1 hour) and 20 minutes is left.
i then add the 5 minutes to the 20 minutes and get 25 minutes.
Since she had already been doing her homework for 40 min. and was not about to do it, i can say she started at 4:25.
make brainliest please
She walks 3 kilometers because 60 divided by 20 is 3
