Find the value of x and y, given the following matrix equation: matrix x = y =

Answers

Based on the given matrix equation, the value of x and y are ±6 and 16 respectively.

How to determine the value of x and y.

In order to solve for the value of x and y, we would create an equation from the upper and lower part of this matrix respectively.

x² - 4 = 32   ...........(upper part)

y + y - 4 = y + 6  ....(lower part)

Next, we would solve for x:

x² - 4 = 32

x² = 32 + 4

x² = 36

x = ±√36

x = ±6.

For the value of y, we have:

y + y - 4 = y + 6

2y - 4 = y + 6

2y - y = 6 + 10

y = 16.

refer to the accompanying data set of mean​ drive-through service times at dinner in seconds at two fast food restaurants. construct a ​% confidence interval estimate of the mean​ drive-through service time for restaurant x at​ dinner; then do the same for restaurant y. compare the results.

Answers

Step-by-step explanation:

Assuming the data is as shown, restaurant X has a mean service time of 180.56, with a standard deviation of 62.6.

The standard error is SE = s/√n = 62.6/√50 = 8.85.

At 95% confidence, the critical value is z = 1.960.

Therefore, the confidence interval is:

180.56 ± 1.960 × 8.85

180.56 ± 17.35

(163, 198)

Restaurant Y has a mean service time of 152.96, with a standard deviation of 49.2.

The standard error is SE = s/√n = 49.2/√50 = 6.96.

At 95% confidence, the critical value is z = 1.960.

Therefore, the confidence interval is:

152.96 ± 1.960 × 6.96

152.96 ± 13.64

The immediate result after DNA replication are one old strand that came back together after replication and one completely new strand that was just assembled two completely new strands of DNA three strands of DNA, one old and two new two strands of DNA that each contain one strand of the original DNA molecule

Answers

Answer:

Two complete new strands of DNA / B

Explanation:

The immediate result after DNA replication is the synthesis of two strands out of which one old strand came back together after replication and one completely new strand was just assembled.

What is DNA replication?

DNA replication may be characterized as a type of biological process through which a copy of the DNA in a cell is made before the cell divides. It is the process of producing two identical replicas of DNA from one original DNA molecule.

DNA replication is the process of copying and duplicating a DNA molecule. The process is carried out in a semiconservative way. This means that the new DNA molecule will consist of two strands: one that is newly created and the other is the original strand. DNA makes multiple copies of itself. It is a biological polymerization, which proceeds in the sequence of initiation, elongation, and termination.

Therefore, the synthesis of two strands out of which one old strand came back together after replication and one completely new strand was just assembled is the immediate result after DNA replication.
