Answer:
21, 42, 63, 84
Step-by-step explanation:
21 2/2=1
42 4/2=2
63 6/2=3
84 8/2=4
The problem can be represented on a Venn diagram, as shown below.
We have P(Day 1 ∩ Day 2) = 0.1 and P(Day 1) = 0.4
We can deduce that 30% of the group ONLY had sandwiches on Day 1 and there's 60% of the group ONLY had sandwiches on Day 2.
We obtain the value 60% = 0.6 from 100%-(10%+30%)=60%
We also can deduce that there 70% of the group that had sandwiches on Day 2
The proportion of people who ate sandwiches on Day 2 GIVEN that they ate sandwiches on Day 1 is given by
P(Day 1 ∩ Day 2)÷P(Day 2) = 0.1÷0.4 = 0.25 = 25%
The statement is TRUE
Answer:
5 cakes
hope it helps
Step-by-step explanation:
if one cake feed 14 people and you are tying to fine out how many cakes you need to feed 60 people you would have to divide 60 by 14
1 cake = 14 people
? cakes = 60 people
60 ÷ 14 = 4.28
so in order to have enough for 60 people you need to round so you would need 5 cakes
to check you answer you can multiply 5 by 14 and you answer should be the amount of people
5 x 14 = 70
why cant it be 4? well because if you buy 4 cakes there wont be enough for 60 people and to make sure it wont be enough you can multiply 4 x 14
4 x 14 = 56
so 4 cakes only feeds 56 people so that is why your answer is 5 cakes are needed
Answer:
the slope of y=3x/7+4/7 is M=3 over 7
we know that
<u>1) If the line segment AB is parallel to the line segment DC</u>
then
m∠1=m∠D -------> by corresponding angles
<u>2) If the line segment AD is parallel to the line segment BC</u>
then
m∠3=m∠B -------> by corresponding angles
