Please Help! I will give you the brainiest and a lot of points! a. How many listened to only rock​ music?
n​(only ​rock)=

b. How many listened to classical and​ jazz, but not​ rock? This is the amount in region VI.

n​(classical and​ jazz, not ​rock)=

c. How many listened to classical or​ jazz, but not​ rock? This is the sum of the amounts in regions​ III, VI and VII.

n​(classical or​ jazz, not ​rock)=

d. How many listened to music in exactly one of the musical​ styles? This is the sum of the amounts in regions​ I, III, and VII.

n​(exactly one ​style)=

e. How many listened to music in exactly two of the musical​ styles? This is the sum of the amounts in regions​ II, IV, and VI.

n​(exactly two ​styles)=

f. How many did not listen to any of the musical​ styles? This is the amount in region VIII.

n​(none)=

because 1.2 isnt half of 6 duh

the answer is a

step-by-step explanation:

because if you put 1 in to the square root of x it equals 300.

infinitely many solutions

step-by-step explanation:

we have been given the equation;

2(2x + 3) = -4 + 2(2x + 5)

we need to determine the value of x.

2(2x + 3), we expand this expression to obtain 4x + 6

similarly 2(2x + 5) will become 4x + 10

now we have;

4x + 6 = -4 + 4x + 10

4x + 6 = 4x + 10 - 4

4x + 6 = 4x + 6

the expression on the left hand side is identical to the one on the right hand side. therefore, we are looking at just a single straight line whose equation is;

y = 4x + 6

consequently, we shall have infinitely many solutions

part 1 answer = 8

part 2 answer = 72

step-by-step explanation:

part 1 explanation = add all of the numbers, then divide by how many numbers you have. so, 200/25 = 8.

part 2 explanation = not gonna lie, this is hard to explain, so just google how to do it.
