The correct answer is 122.
The proportion of students who prefer pizza is 67/206, since 67 out of the 206 total students prefer pizza.
Out of 375 students, we would expect (67/206)(375) = 121.97 ≈ 122 students to prefer pizza.
Answer:
20x² + 25 x + 8
Step-by-step explanation:
f(x) = 4x² + 5x + 3
g(x) = 5x -7
Then:
g(f(x)) = 5(4x² + 5x + 3) -7
g(f(x)) = 20x² + 25x + 15 - 7
g(f(x)) = 20x² + 25x + 8
Answer:
x = 15 in
you can use the Pythagorean Theorem because you know the legs of the triangle and need to find the hypotenuse
the left leg of the triangle is 9 because 9² = 81
the bottom leg of the triangle is 12 because 48/4 = 12
9² + 12² = x²
81 + 144 = x²
225 = x²
√225 = x
