Answer:
-5/7
Step-by-step explanation:
Tip: Dividing by a fraction is the same as multiplying by the reciprocal of the fraction
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
16/7 is already in lowest terms. It cannot be further reduced.
You can write this fraction as a decimal by simply dividing the top by the bottom.
So, 16/7 = 2.2857142857
Nothing else can be done here.
A:
Coefficient is a number multiplied by an unknown variable. Both 10.50 and 15 are coefficients
B:
You plug in the given values into the provided formula.
10.50(37) + 15(12) + 50
388.50 + 180 + 50 = 618.50
C:
Only the coefficient 10.50 would change to 11.25, because this is a representation of the dollar amount per hour that she works.
Answer:
28 m squared
Step-by-step explanation:
LA=Perimeter of base times height
perimeter of base: 14 times pi
height: 2
14 times 2
28 m squared
