Answer: Using compatible numbers can help estimate the solution to many problems. In this case, the equation is 37x24. Compatible numbers are anything that is a multiple of 5. For example, 5, 10, 15, 20, etc. Rounding 37, to 35, and 24 to 25, you can multiply. Whatever you get, can infer what the answer or the answer range is.
Hoi!
To find the volume, multiply the three known values.
6 × 4 × 5 = 120
The volume of this figure is 120 inches.
Since the compiler reads top down, it should print “yesno” because they are both true
Answer:
P(B | T)=3/13
Step-by-step explanation:
The question is missing the Venn diagram that shows the value of each variable.
From the Venn diagram we can see there are 10 paintings that not T and not B. That means the total number of paintings that either T or B is
P(T∪B) = 60-10= 50 paintings.
There are x(x-2) + x paintings from 20th century
P(T)= x(x-2) + x = x^2 - x
There are 2x+8 +x British paintings.
P(B)= 2x+8 +x = 3x +8
There are 2 paintings that both T and B
P(T∩B)= x
Using union equation we can find the x
P(T∪B) = P(T) + P(B) - P(T∩B)
50= x^2 - x + 3x +8 - x
x^2 + x + 8 - 50 = 0
x^2 + x + -42 =0
(x-6) (x+7)=0
x1= 6 x2=-7
Since x can't be minus, then x=6.
The question asking how much conditional probability that a random T paintings is also British. The calculation will be:
P(B|T)= P(B∩T) / P(B) = x/ (3x +8)= 6/(6*3+8)= 6/26= 3/13
The correct answer for this question is 68.
