Simple the fraction into the population of the x and times it by Z
Answer:
The degree of the polynomial ≈ 4
Step-by-step explanation:
The degree of a polynomial, is given by the highest value of the sum of the exponents (powers) of the of the variables (monomials) that are present in the polynomial expression
The given polynomial expression is x²·y² + y³ + 4
The sum of the exponents; 2 + 2 = 4, and 3
The sum of exponents 4 > 3
Therefore, the degree of the polynomial = 4.
Answer:
A
Step-by-step explanation:
Using Pythagoras' identity in the right triangle.
The square on the hypotenuse is equal to the sum of the squares on the other 2 sides, that is
BC² = 9² + 12² = 81 + 144 = 225 ( take the square root of both sides )
BC = = 15 → A
Answer:

increases and remained the same.
Step-by-step explanation:
I just took the test and got it correct.
The probability that the teacher selects both boys from a seventh grader and eighth grader.
first calculate the probility that it is boy in each grade
7th
x = 7 / ( 7 + 3) = 7 / 10
8th
y = 2 / (2 + 2) = 1 / 2
so the probability
P = ( 7 / 10 ) ( 1 / 2 )
P = 0.35
