stira [4]

Step-by-step explanation:

Let

Carl grades = x = 62, 78, 59, 89

Number of grades, N = 4

Mean of Carl's grade = sum of x / number of grades,N

= 288/4

= 72

Therefore, mean of Carl's grade = 72

If s(x) = x – 7 and t(x) = 4x2 – x + 3, which expression is equivalent to (t*s)(x)
lesya [120]
S(x) = x - 7; t(x) = 4x² - x + 3

(t · s)(x) = (4x² - x + 3)(x - 7) = (4x²)(x) + (4x²)(-7) - (x)(x) - (x)(-7) + (3)(x) + (3)(-7)

= 4x³ - 28x² - x² + 7x + 3x - 21 = 4x³ - 29x² + 10x - 21
