Answer:
Volume of the box = 48 cubic meter
Step-by-step explanation:
Given:
Total number of cubes used = 48 cubes
Length of each cube = 1 meter
Find:
Volume of the box
Computation:
Volume of each cube = Side³
Volume of each cube = 1³
Volume of each cube = 1 cubic meter
Volume of the box = 48[Volume of each cube]
Volume of the box = 48[1 cubic meter]
Volume of the box = 48[1]
Volume of the box = 48 cubic meter

Jaylin Earned $36 for 3 hours of work and $60 for 5 hours of work. What is the Constant of Proportionality?
Jamal treated his family to a fancy brunch. Their brunch cost $250, and the local sales tax
was 4%. If Jamal left an 18% tip on the $250, how much in total did he pay?
Answer:
306.80
Step-by-step explanation:
250 + 4% = 260
260 + 18% = 306.80
Total amount paid by Jamal is $305
Step-by-step explanation:
Given that;
Cost of meal = $250
Local sale tax rate = 4%
Percentage of tip left by Jamal = 18%
Find:
Total amount paid by Jamal
Computation:
Total tax paid by Jamal = 250 × 4%
Total tax paid by Jamal = $10
Total amount of tip left by Jamal = 250 × 18%
Total amount of tip left by Jamal = $45
Total amount paid by Jamal = Cost of meal + Total tax paid by Jamal + Total amount of tip left by Jamal
Total amount paid by Jamal = 10 + 45 + 250
Total amount paid by Jamal = $305

ATCs are required to undergo periodic random drug testing.
A simple, low-cost urine test is used for initial screening. It has been reported that this particular test has a sensitivity and specificity of 0.96 and 0.93. This means that if there is drug use, the test will detect it 96% of the time. If there is no drug use, the test will be negative 93% of the time.
Based on historical results, the FAA reports that the probability of drug use at a given time is approximately 0.007 (this is called the prevalence of drug use).
Draw a probability tree for the situation. (Use this order for the tree: Drug Use(yes/no) -> Test Result(+/-) -> Joint Probabilites)
A positive test result puts the air traffic controller’s job in jeopardy. What is the probability of a positive test result?
Find the probability an air traffic control truly used drugs, given that the test is positive.
Answer:
The responsess to the given question can be defined as follows:
Step-by-step explanation:
[tex]P(medication\ used) = 0.007 \\\\P( drug \not\ used ) = 1 - 0.007 = 0.993\\\\P(test\ positive | medication \ used) = 0.96 \\\\ P(test \ negative | medication \ used) = 1 - 0.96 = 0.04\\\\[/tex]
[tex]P(Point | Non-used\ medication )=0.93\\\\ P(Point |No\ medication ) = 1 - 0.93 = 0.07[/tex]
As per the given info we draw the tree diagram which is defined in the attachment file.
[tex]P ( test \ is\ positive ) = P( medication \ used ) \times P( Test \ positive | medication \ used ) + P( medication not \ used ) \times P( Test\ positive | medication \ not \ used )[/tex]
[tex]= ( 0.007 \times 0.96 ) + ( 0.993\times 0.07 )\\\\= 0.0762[/tex]
[tex]P( medication \ used | test\ positive )= \frac{\textup{P( medication used ) *P( Test positive given medication used )}}{\textup{P( medication used )}}[/tex]

Which of the following is the correct point-slope equation for the line that
passes through the point (-3,-9) and is parallel to the line given by
y = 2.5x - 20?
A. Y-3 = 2.5(x-9)
B. y + 3 = 2.5(x + 9)
C. y + 9 = 2.5(x + 3)
O D. y-9 = 2.5(x-3)
Answer:
C. [tex] y + 9 = 2.5(x + 3) [/tex]
Step-by-step explanation:
Point-slope equation takes the form of [tex] y - b = m(x - a) [/tex].
Where,
a and b area coordinates of a point the line passes through. In this case, a = -3, and b = -9
m = slope, in this case, slope will be the same as the slope value of the line it is parallel too = 2.5.
Substitute a = -3, b = -9 and m = 2.5 into [tex] y - b = m(x - a) [/tex].
Thus:
[tex] y - (-9) = 2.5(x - (-3) [/tex]
[tex] y + 9 = 2.5(x + 3) [/tex]

In certain regions of the country, elk can cause damage to agricultural crops by walking through the fields. One strategy designed to limit elk from crossing a field is to surround the field with a fence. Some elk, however, will still be able to bypass the fence. For a period of one month, the number of elk found crossing a sample of fields with a fence was recorded and used to construct the 95 percent confidence interval (2.9,4.4) for the mean number of elk. Assume that the conditions for inference were checked and verified.
Required:
The interval (2.9, 4.4) provides convincing statistical evidence which claims?
Answer:
The mean number of elk to cross all fields protected by fence is equal to 3.65 per month.
Step-by-step explanation:
Given the confidence interval : (2.9,4.4)
Confidence = xbar ± standard Error
To obtain the mean :
We first calculate the standard error :
Standard Error from confidence interval :
(Upper boundary - Lower boundary interval) / 2
(4.4 - 2.9) / 2
1.5 / 2
= 0.75
Hence, the mean can be obtained as :
(Lower boundary + 0.75) or (Upper boundary - 0.75)
Lower boundary + 0.75 = 2.9 + 0.75 = 3.65
Upper boundary - 0.75 = 4.4 - 0.75 = 3.65

Answer:
x = 39
Step-by-step explanation:
The Pythagorean theorem tells you the sum of the squares of the sides of a right triangle is the square of the hypotenuse.
x² +80² = 89²
x² = 89² -80² = 7921 -6400 = 1521
x = √1521

Answer:
316.2 m/s
Step-by-step explanation:
What the problem statement doesn't tell you is that the value of m in the formula must have units of kilograms. 17 grams is 0.017 kilograms, so the velocity is ...
[tex]v=\sqrt{\dfrac{2K}{m}}=\sqrt{\dfrac{2(850)\text{ J}}{0.017\text{ kg}}}=\sqrt{100\,000}\text{ m/s}\approx316.2\text{ m/s}[/tex]
_____
Additional comment
If you simply put the numbers into the formula without regard to correct units, you might be led to believe the velocity is 10 m/s. That would be the speed of a 17 kg object with an energy of 850 J.

4 When Janelle was born, her grandmother put $200 into a college savings account for her.
Each month, her grandmother adds $50 to the account. Which inequality can be used to find
m, the number of months it will take for Janelle's savings account to have more than $1,250
in savings?
A 200m + 50 > 1,250
B 200 + 50m > 1,250
C 200 + 50m < 1,250
D 200m + 50 < 1,250
Answer:
B
Step-by-step explanation:
200+50m >1250
This means that for every month her grandmother gives 50 for an unknown amount of months along with the first 200 dollars.
The greater than 1250 shows that until she is greater than 1250 she'll keep getting money

Answer: 5/6
Step-by-step explanation:
If you chose \(\frac{5}{6}\) foot, you are correct. If you chose 10 feet, you forgot to convert inches to feet. If you chose 1 foot, you thought that there were 10 inches in a foot. If you chose \(\frac{1}{10}\)foot, you wrote 1 over the number of inches because you were unsure how to write fractions in terms of feet.

In a completely randomized experimental design involving three assembly methods, 30 employees were randomly selected and 10 were assigned to each of the three methods. The time required to complete the task was recorded. The following information is provided: MSTR = 45.89 and MSE = 6.27. What is the critical value of F if we want to determine whether the means of the three populations are equal at the 5% level of significance?
Answer:
The answer is "3.35".

Treatment independence degree
[tex]= 3 - 1 \\\\= 2[/tex]
Grade of error independence
[tex]= 30 - 3 \\\\= 27[/tex]
[tex]\alpha = 0.05[/tex]
F is the critical value[tex]= 3.35[/tex]

Can you construct a triangle with side lengths of 1 meter, 7 meters, and 8 meters?
Yes or no and explain
Answer:
No.
Step-by-step explanation:
No.
Each side of a triangle must have a length between the difference and the sum of the lengths of the other two sides.
Let's look at the sum and difference of lengths of 2 sides.
Side with length 1 and side with length 7; third side with length 8
sum of lengths of first two sides = 1 + 7 = 8
difference = 7 - 1 = 6
The third side would have to have a length between 6 and 8. The third side has a length of 8. For a triangle, the third side must be between the sum and difference. Here, the third side is equal to the sum, so there is no triangle.
As soon as one side does not work, there is no triangle, and you don't need to check the sums and differences of the other two sets of two sides.

Cooper Bank Ballpark charges 87 per ticket (t) and $3 to park. Good Foods
Ballpark charges $6 per ticket, and $10 to park. At how many tickets will the
total cost (c) be the same?
Answer:
13.33
Step-by-step explanation:
let p be park.
[tex]t+p = c\\\\t_{2}(x) + p_{2} = c[/tex]
[tex]\\(87)+(3) = 90\\\\(6)x+(10) = 90[/tex]
(6)x needs to make up 80 to get the total cost(c)
80/6 = 13.33
so x should be 13.33
