Charlie does a weekly exercise program consisting of cardiovascular work and weight training. Each week, he exercises for at least 9 hours. He spends at most 12 hours on weight training. He spends at most 6 hours doing cardiovascular work. Let x denote the time (in hours) that Charlie spends doing cardiovascular work. Let y denote the time (in hours) that he spends on weight training. Shade the region corresponding to all values of x and y that satisfy these requirements.

Answers

Answer:

[tex](x_1,y_1) = (0,9)[/tex]

[tex](x_2,y_2) = (6,3)[/tex]

[tex](x_3,y_3) = (6,12)[/tex]

Step-by-step explanation:

Given

x = hours spent on cardiovascular work

y = hours spent on weight training

From the first statement,

Each week: he spends at least 9 hours

This is represented as:

[tex]Total \ge 9[/tex]

[tex]x + y \ge 9[/tex]

From the second statement,

Each week: he spends a max of 12 hours on weights

This is represented as:

[tex]Weight \le 12[/tex]

[tex]y \le 12[/tex]

From the third statement,

Each week: he spends a max of 6 hours on cardio works

This is represented as:

[tex]Cardio \le 6[/tex]

[tex]x \le 6[/tex]

So, the inequalities are:

[tex]x + y \ge 9[/tex]

[tex]y \le 12[/tex]

[tex]x \le 6[/tex]

See attachment for the graph where the solution are also highlighted

From the attachment, the solutions are:

[tex](x_1,y_1) = (0,9)[/tex]

[tex](x_2,y_2) = (6,3)[/tex]

[tex](x_3,y_3) = (6,12)[/tex]

A quality control engineer Is interested in the mean length of sheet insulation being cut automatically by machine. It is known that the standard deviation in the cutting length that this machine produces is 0.15 feet. A sample of 70 cut sheets yields a mean length of 12.14 feet. This sample will be used to obtain a confidence interval for the mean length cut by machine. Referring to problem statement, the Z value to use in obtaining the 99% confidence interval is approximately .A.1.645B. 1.96C.3.23D.2.58

Answers

Answer:

D.2.58

Step-by-step explanation:

We have that to find our [tex]\alpha[/tex] level, that is the subtraction of 1 by the confidence interval divided by 2. So:

[tex]\alpha = \frac{1 - 0.99}{2} = 0.005[/tex]

Now, we have to find z in the Ztable as such z has a pvalue of [tex]1 - \alpha[/tex].

That is z with a pvalue of [tex]1 - 0.005 = 0.995[/tex], so Z = 2.58.

Find the side of a square whose diagonal measures 15 square root of 2

Answers

Answer:  15 units .

__________________________________________________

In this case, a square, the two sides of the square (forming a right triangle) are equal), and the "diagonal" forming is the hypotenuse of the right triangle.

In these cases, the measurements of the angles of the right triangle are "45, 45, 90" ; and the measurements of the sides are:  "a, a, a√2" ; in which "a√2" is the hypotenuse.

We are given:  "15√2" is the hypotenuse" ; and we are given that this is a right triangle of a square with a diagonal length (i.e. "hypotenuse" of "15√2" ; so the measure of the side of the "square" (and other two sides of the triangle formed) is:  15 units.   (i.e.,  15, 15, 15√2 ).

C.
Kari, because her grade will increase to 85.3.

D.
Jocelyn, because her grade will increase to 84.

Answers

Answer:

A

Step-by-step explanation:

Part A, A. Kari, because the mean and median of her scores is, 84.5.

Part B, Jocely will see a greater increase overall as her previous average is less.

What are mean, median, and mode?

The three main methods for identifying the average value of a set of integers are mean, median, and mode.

Adding the numbers together and dividing the result by the total number of numbers in the list yields the arithmetic mean.

The middle value in a list that is arranged from smallest to greatest is called the median.

The value that appears the most frequently on the list is the mode.

From the given information, The average score of Jocelyn is,

= (86 + 87 + 95 + 72 + 78 + 80)/6.

= 83.

And Similarly, The average score Kari is,

= (88 + 78 + 93 + 81 + 75 + 91)/6.

= 84.5.

Therefore, Kari scores better overall.

If they both get 90% on their next math quiz Jocely will see a greater increase overall as her previous average is less.

What is 6/11 in decimal form, to the nearest thousandth

Answers

Answer:

0.006

Step-by-step explanation:

Answer:

Explanation:

611 or 6÷11=0.545454545....

The hundredth position is two positions to the right of the decimal point. For this problem it is the 4:

0.545454545....

To round to the nearest hundredth you must look at the digit in the position immediately to the right of the digit in the hundredth place, which is the 5 in the thousandth place:

0.545454545....

If the digit to the right is greater than or equal to 5 you add 1 to the digit you are rounding to and make everything to the right 0.

If the digit to the right is less than 5 you add keep the digit you are rounding to the same and make everything to the right 0.

In this problem the digit to the right is a 5 so we add 1 to the digit we are rounding to and make everything to the right 0.

0.545454545....=0.550000000....=0.55
