Brainliest for the correct awnser!! A calculator was used to perform a linear regression on the values in the table. The results

marin [14]

Answer:

Option B

Step-by-step explanation:

Taking the derivative of the residual function, then applying the normal equation:

[a; b] = (X'*X)^(X'*y)

with

X = [1 1; 2 1; 3 1; 4 1; 5 1]

X' is transpose of X

y = [11; 8; 4; 1; 0]

[a; b] = [-2.9 13.5]

Last year, a person wrote 126 checks. Let the random variable x represent the number of checks he wrote in one day, and assume

Arisa [49]

Answer: The mean number of checks written per day $=0.3452$

Standard deviation $=0.5875$

Variance $=0.3452$

Step-by-step explanation:

Given : The total number of checks wrote by person in a year = 126

Assume that the year is not a leap year.

Then 1 year = 365 days

Let the random variable x represent the number of checks he wrote in one day.

Then , the mean number of checks wrote by person each days id=s given by :-

$\lambda=\dfrac{126}{365}\approx0.3452$

Since , the distribution is Poisson distribution , then the variance must equal to the mean value i.e. $\sigma^2=\lambda=0.3452$

Standard deviation : $\sigma=\sqrt{0.3452}=0.5875372328\approx0.5875$

Solve this step by step using the quadratic function y=x^2 +x+2

Ne4ueva [31]

Answer:

x=+ $\frac{\sqrt{4y-7}-1 }{2}$

Step-by-step explanation:

Quadratic function =( -b+ $\sqrt{b^2+4ac}$ )/2a

x^2+x+2-y=0

x=-1+ $\sqrt{1^2-4(2-y)}$ /2

x=-1+ $\sqrt{4y-7}$ /2

x=+ $\frac{\sqrt{4y-7}-1 }{2}$

Pretty sure this is right. Would appreciate a brainliest
