Daniela painted a photo that was 4/5 afoot by 1 7/8 of afoot. What was the area?
Answers
Answer:
[tex]\frac{3}{2}[/tex] square feet
Step-by-step explanation:
The dimensions of the photo is 4/5 by 1 7/8 of a foot.
But,
1 7/8 = [tex]\frac{15}{8}[/tex] feet
So that,
length of the photo = [tex]\frac{15}{8}[/tex] feet
width of the photo = [tex]\frac{4}{5}[/tex] feet
The area of the photo = length x width
= [tex]\frac{15}{8}[/tex] x [tex]\frac{4}{5}[/tex]
= [tex]\frac{60}{40}[/tex]
= [tex]\frac{3}{2}[/tex]
Area of the painted photo is [tex]\frac{3}{2}[/tex] square feet.
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.
The answer is given by option D.

Find the 96th term of the arithmetic sequence-30,-32,34
Answers
Answer:
a = -30
d = -32 - (-30) = -2
n = 96
So, using A.P. formula-
Tn = a + (n-1) d
T96 = -30 + (96-1) -2
T96 = -30 + (95) -2
T96 = -30 - 190
T96 = -220

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

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.
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.

the thief with the stolen accordion has been traveling on a raft for 2 hour 40 minutes from Village Ivanovo toward Village Sosnovka. Aniskin immediately leaves Sosnovka in a motorboat and travels upstream toward the raft. Aniskin catches the thief 27 km from Sosnovka. Find the speed of the raft if the speed of the motorboat in still water is 12 km/h and the distance from Ivanovo to Sosnovka is 44 km.
Answers
Answer:
3 km/hStep-by-step explanation:
Let the speed of raft (current) - rSpeed of motorboat - 12 km/hThe distance between villages - 44 kmLet the time spent by Aniskin - tThe time the thief was in travel = 2 hr 40 min + t = 2 40/60 + t = 3/8 + tThe distance the thief traveled = 44 - 27 = 17 kmWe have following equations:
r(8/3 + t) = 17(12 - r)t = 27Simplify the equations:
r(8/3 + t) = 17 ⇒ rt + 8/3r = 17(12 - r)t = 27 ⇒ 12t - rt = 27Add up the equations and solve for r:
rt + 8/3r + 12t - rt = 448/3r + 12t = 44r = 16.5 - 4.5tSubstitute r into second equation:
(12 - 16.5 + 4.5t)t = 274.5t² - 4.5t = 279t² - 9t - 54 = 0Solving we get
t = 3 hFind r:

what operation do you use to convert from a larger measurement unit to a smaller measurement unit?explain why.
Answers
Answer:
Multiplication
Step-by-step explanation:
To convert from a larger unit to a smaller unit, we multiply. This is because the number will become greater since the unit is smaller.
Example:
1 m ⇒ ×100 ⇒ 100 cm
We use division when converting from a smaller unit to a larger unit since the number will become smaller as the unit becomes greater.
Example:

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 ).
