Answer:
(B) A location
Step-by-step explanation:
If you have a point on a graph or number line, it always represents a certain location on the graph.
For instance, if we have a point on the x=3 line and the y=4 line, the point would represent the location (3,4).
Hope this helped!
Average = Mean
Mean → Add all the numbers and divide by how many there are
3 + 9 + 14 + 5 + 8 + 12 + 7 = 58
There are 7 numbers.
58 ÷ 7 = 8.3
Answer = 8.3
Hope this helped :)
Answer:
a)0,45119
b)1
Step-by-step explanation:
For part A of the problem we must first find the probability that both people in the couple have the same birthday (April 30)
Now the poisson approximation is used
λ=nP=80000*1/133225=0,6
Now, let X be the number of couples that birth April 30
P(X ≥ 1) =
1 − P(X = 0) =
P(X ≥ 1) = 0,45119
B) Now want to find the
probability that both partners celebrated their birthday on th, assuming that the year is 52 weeks and therefore 52 thursday
Now the poisson approximation is used
λ=nP=80000*52/133225=31.225
Now, let X be the number of couples that birth same day
P(X ≥ 1) =
1 − P(X = 0) =
P(X ≥ 1) = 1
The number sentence would end up being 7×6=42
So this meeting room is 3 by 19 by 12
surface area/wall area=2(height times width)+2(height times depth)+2(width times depth)
lets say 3=height
depth=19
width=12
2(3 times 12)+2(3 times 19)+2(12 times19)=2(36)+2(57)+2(228)=72+114+456=642
2 coats of paint so surface area times 2
642 times 2=1284
assuming 30m means 30 <u>square</u> meters we divide 1284 by 30 and get
1284/30=42 and 4/5 or 42.8
then find how many cans by dividing by 4
42.8/4=10 and 1.4/2=10.7, but you cant buy 0.7 of a can so round up and get
11 cans of paint
he needs 11 cans of paint
