Answer 1

Answer:

1. 1 1/8= 18/16

5/16*2= 10/16

4/16*2= 8/16

9/16= 9/16

1/2= 8/16

18/16 + 10/16 + 8/16 + 9/16 + 8/16= 53/16

Simplify:

4 & 5/16sq ft

What is the value of the system determinant for the following system of equations? 6x + y = 4 5x + y - 7 = 0

Answers

Answer: The value of the determinant is 1.

Step-by-step explanation: The given system of linear equation is as follows:

$6x+y=4~~~~~~~~~~~~~~~~(i)\n\n5x-y-7=0\n\n\Rightarrow 5x-y=7~~~~~~~~~~~(ii)$

The first column of the determinant gives the coefficients of 'x' and the second column gives the coefficients of y in the two equations.

Therefore, the determinant for the given system is

$D=\begin{vmatrix} 6& 1\n 5& 1\end{vmatrix}=6* 1-5* 1=6-5=1.$

Thus, the required value of the determinant is 1.

Step-by-step explanation:

Alice works at a health care facility. She has measured the hemoglobin levels of 200 people. The data follows a normal distribution with a mean of 14 g/dL and a standard deviation of 1. From the given data, we can conclude that about people have hemoglobin levels less than 13, and about people have hemoglobin levels greater than 14.

Answers

Since the data follows a normal distribution, the 68-95-97 rule can be used to describe the number of people falling under N standard deviations from the mean. Since the standard deviation is 1, hemoglobin levels of 13 -15 g/dL contains 68% of the sample, or 136 people. This means the 32 people have less than 13 g/dL and 32 people have more than 15 g/dL.
