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

Step-by-step explanation:
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
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.
The answer is given by option D.
Use the information to answer the following questions.
Jocelyn and Kari’s math quiz scores are shown.
Jocelyn: 86, 87, 95, 72, 78, 80
Kari: 88, 78, 93, 81, 75, 92
Activity 1 of 2
Part A: Based on the samples, which student generally has higher quiz scores?
A.
Kari, because the mean and median of her scores is 84.5.
B.
Kari, because the range of her scores is 18.
C.
Jocelyn, because the interquartile range of her scores is 9.
D.
Jocelyn, because she had a maximum score of 95.
Activity 2 of 2
Part B: Suppose both girls got a 90% on their next math quiz. Which student will see a greater increase in her overall math grade?
A.
Jocelyn, because her grade will increase by 1 point.
B.
Kari, because her grade will increase by 0.8 points.
C.
Kari, because her grade will increase to 85.3.
D.
Jocelyn, because her grade will increase to 84.
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.

Answer:
2/5 remaining
Step-by-step explanation:
If a job is 35 and 3/5 was completed, 3/5 of 35 = 21

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