Answer:
The cost of the 1 muffin is $1.5 and 1 quart of milk cost is $3 .
Step-by-step explanation:
Let us assume that the cost of one muffins be x.
Let us assume that the cost of one 1 quarts of milk be y.
As given
The cost of 8 muffins and 2 quarts of mil is $18.
Than the equation becomes
8x + 2y = 18
As given
The cost of 3 muffins and 1 quart of milk is $7.50.
Than the equation becomes
3x + 1y = 7.50
Two equations are
8x + 2y = 18 and 3x + 1y = 7.50
Multiply 3x + 1y = 7.50 by 2 and subtracted from 8x + 2y = 18 .
Thus
8x - 6x + 2y - 2y = 18 - 15
2x = 3
x = 1.5
Put x = 1.5 in 3x + 1y = 7.50
3 × 1.5 + y = 7.50
y = 7.50 - 4.5
y = 3
Therefore the cost of the 1 muffin is $1.5 and 1 quart of milk cost is $3 .
Answer:
Yes, the two events are independent because P(NF|PB)=P(NF).
Step-by-step explanation:
The least common multiple of 27 and 36 is 108.
The least common multiple is defined as the smallest multiple that two or more numbers have in common.
Given that, what is the least common multiple of 27 and 36,
To find the LCM of 27 and 36, we need to find the multiples of 27 and 36 Multiples of 27 = 27, 54, 81, 108;
Multiples of 36 = 36, 72, 108, 144
The smallest multiple that is exactly divisible by 27 and 36, is 108.
Hence, the least common multiple of 27 and 36 is 108.
