Answer:
Lily babysit for <u>less than 4 hours</u>.
Step-by-step explanation:
Given:
Lucy spends in a week babysitting for 4 hours.
Lily spends seven-eighths of 4 hours.
Now, to find whether Lily babysit for more than 4 hours or less than that.
Number of hours Lucy babysit = 4 hours.
So, to get the hours Lily babysit:
<em>On simplifying we get:</em>
<u><em>Thus, Lily spends </em></u>
<u><em> for babysitting which is less than 4 hours.</em></u>
Therefore, Lily babysit for less than 4 hours.
Hi there,
I’m attaching the same image with more information on the graph.
The 4th mark (the middle dashed line) is marking the mean (70).
The 3rd and the 5th are marking the mean less/plus 1 deviation.
So, 70.5 is the 5th mark.
Taking this into account:
The probability of selecting a container that has less than 70.5 is 0.1% + 2.2% +13.6% 34.1% + 34.1% = 84.1%
The probability of choosing more than 70,5 = 13.6% + 2.2% +0.1% = 15.9%
Good Luck!
X4 + 8 = -36
x4 = -44
x = -11
(-11)4 + 8 = -36
-44 + 8 = -36
-36 = -36
I can't seem to find answers for #1-3 but I found the answer for #7, a common track is 400 meters, so I split that into thirds which equals 133.333333 meters, then I split a minute into quarters which equals 15 seconds so she is running 133.333333 meters every 15 seconds. So the answer is 45 seconds is all it takes her to run 400 meters.
I hope this helps.
