I think what you need to do is make B = -5
3a = -2(-5) - 7
3a = 10 - 7
3a = 3
a = 1
Answer:
120 pounds I think
Step-by-step explanation:
D because some of the inputs have the same output therefor it is not a function
The best option is C. 0.0823mean = np = 48*1/4 = 12
SD = sqrt(npq) = sqrt(48 *1/4 *3/4) = 3
aplying continuity correction for using a continuous distribution for a discrete one,
"exactly 15" means 14.5 to 15.5
z1= (14.5-12)/3 = 0.833 , z2 = (15.5-12)/3 = 1.167
P(0.833 < z < 1.167) = 0.0808
Answer:
14
Step-by-step explanation:
f(-2) = 3(-2)² + 1 = 3(4) + 1 = 12 + 1 = 13
