Answer:
each person can get 3/12 if you split the 3.4 twice.
Step-by-step explanation:
make a circle
split one line down the middle and the other horizontal.
color is one of the corners. you will not use it. this is the part of the cake they already ate.
now you have three remaining parts.
split each one of the remaining heart down the middle.
now you have six remaining slices.
6 is not divisible by 4.
split the sixths down the middle one more time.
now you should have 12.
12 is divisable by 4.
give each person 3 out of 12 slices of cake.
it is just enough to feed all 4 people.
My guess is 30 mins sorry if wrong hope this helps
Answer:
78 rounds to 80, so find 10% of 80 and double it. 10% of 80 is 8. So, 20% of 80 is 16. Then, 22% of 78 is a little more than 16.
78 rounds to 80, and 22% is a little less than 25%. 25% (or one-fourth) of 80 is 20. So, 22% of 78 is a little less than 20.

Answer:
Cross Sectional
Step-by-step explanation:
A cross sectional is one in which an association is developed between a risk factor or an outcome.
In the given question the device is used to record the viewing habits of about 2500 households, and the data collected today will be used to determine the proportion of households tuned to a particular news program. There will be risk factor in today's research with the future developed program which will the outcome.
For example there are 20 students in my class who cannot write. So I develop a program to help them write. But the next year there may not be any student who would require such help.So there's a risk factor associated with the outcome.
Cross sectional results are recorded in a two ways table showing do's and don'ts.
