Answer:
Positive product
Step-by-step explanation:
So first of the equation is p(n)=n^2-2n. So now we just plug in -7. p(-7)=-7^2-2(-7). after solving that you get p(-7)=63.
Answer: 0.3061.
Step-by-step explanation:
Given : The temperature reading from a thermocouple placed in a constant-temperature medium is normally distributed with mean
, the actual temperature of the medium, and standard deviation
.
Let X be the random variable that represents the reading of the thermometer.
Confidence level : 
We know that the z-value for 95% confidence interval is 1.96.
Then, we have

But all readings are within 0.6° of
.
So,

Hence, the required standard deviation will be
Answer:
x = 2
Step-by-step explanation:
x = 2 represents the entire vertical line of positive 2 on the x-axis. That is where the shape of the function becomes symmetrical.
Answer: $4840
Step-by-step explanation:
A = p(1+r/n)^nt
A = 2800(1+0.043)^13
A = 4840
