Answer:
a = 3, b = 8
Step-by-step explanation:
Since x+3 is a factor, x=-3 is a root. => f(−3)=2(−3)3+a(−3)2−b(−3)+3=0
=> 9a+3b=51 => 3a+b=17 — (1)
x-2 leaves a reminder of 15 => f(2)=2(2)3+a(2)2−b(2)+3=15
=>4a−2b=−4=>2a−b=−2 —- (2)
Adding (1) & (2), 5a=15=>a=3
Substituting the value of a in (1), b=8
Answer:
Erin
Step-by-step explanation:
Z score formula:
z = (x-μ)/σ, where x is the raw score, μ is the population mean, and σ is the population standard deviation.
For Candice:
Z score = 74 -66/4
Z score = 2
For Erin
Z score = 58 - 42/7
Z score = 2.28571
Erin z score is larger hence, he did better
