The table shows the depths of four plants.
Order the numbers from least to greatest.
Answer:
-20 3/4, - 15 1/2, - 14 3/4, - 1/4
Step-by-step explanation:
Given the depths :
-14 3/4, - 15 1/2, - 1/4, - 20 3/4
Ordering from least to greatest :
Since the numbers are negative; arranging the numbers as it would appear on a number line ; Large whole number negative values are always the least.
-20 3/4, - 15 1/2, - 14 3/4, - 1/4

The original price of a membership for a food delivery service was $60.00 per week. However, the food delivery service is having a promotion right now. Currently the service is 25% off and an 8% sales tax is added to the promotional price.
How much does the food delivery service currently cost with tax?
Enter your answer in the box.
$
60 x 25% = 15
60 - 15 = 45
45 x 8% = 3.6
45 + 3.6 = 48.6

the perimeter of a square field is 880m. Find it's area in hectares
This is the answer hope it helps
The area of the square field is 4840 hectares.
What is perimeter of square?Perimeter of the square is defined as addition the lengths of the square's four sides.
Perimeter of the square equation is 4a
Where, a is length of the square
Given data as :
Perimeter of the square field = 880 m
Side of the square = Perimeter/4
Side of the square = 880/4
Side of the square = 220 m
So, length of each side of the square is 220 m
Area of square = Side × Side
Area of square = 220 m × 220 m
Area of square = 48400 square meters
Area of square = 48.4 square kilometers
As we know that 1 sq km = 100 hectares
So, 48.4 km = 48.4 × 100 = 4840 hectares
Hence, the area of the square field is 4840 hectares.

For the following scenarios, determine whether or not they represent paired samples.
a. Test scores for students in a biology class taught by Professor Quick are being compared to test scores in a different section of the biology class taught by Professor Quack
b. Pulse rates for students at the beginning of class are being compared to pulse rates for the same students at the end of class.
c. The weights of 10-year-olds in 2009 are being compared to the weights of 10- year-olds in 1994.
Answer:
A = Not a paired sample
B = paired sample
C = Not a paired sample
Step-by-step explanation:
Paired samples also commonly referred to as dependent samples are often characterized by having to different data points which are taken at different times, location and so on. Such that each pair of data points or observation can be matched based on the basis of the subject or sample name usually for the sake of analysing if any statistical difference exists between the occurrence of each observation.
For the instances given above ;
a.) this isn't a paired sample, because Professor Quick and Professor Quacks students are different, hence each student has only one reading and as such a match of the two test scores cannot be made on the basis of student name or identity. Hence, it is not a paired sample
B.) This is a paired sample, two different readings are available for each students ; one at the beginning, the other at the end. Hence, it is a paired sample
C.) This is not a paired sample, because the subjects used to obtain the weight of 10 year old in 1994 aren't the same samples used in 2009

Find the slope and the y-intercept of the line. 6x + 3y = -3 Write your answers in simplest form
Answer:
[m] slope = -2
[b] y-intercept = -1 ; (0, -1)
[y = mx + b] slope-intercept = -2x – 1
Step-by-step explanation:
Given the algebraic equation 6x + 3y = -3 currently in standard form:
Ax + By = C →
By = C – Ax →
By = -Ax + C →
y = -Ax / B + C / B →
y = (-A / B)x + (C / B) →
y = mx + b →
m = -A / B. b = C / B.
6x + 3y = -3
↓ ↓ ↓
A = 6. B = 3. C = -3.
[Substitute]
m = -A / B. b = C / B
m = -(6) / (3). b = (-3) / (3)
↓ ↓
m = -2. b = -1.
↓. ↓
Slope = -2. y-intercept = -1.
_______________________
Slope is ∆y/∆x [change in y over the change in x] = y2 – y1 / x2 – x1.
The y-intercept is the point where x is 0.
The easiest way to determine this is to substitute 0 in for x in an equation and solve for y.
This means that the y intercept in coordinate form is (0, b).
Find the distance between A (-1, 9) and B (-4, 1). Leave your answer in exact radical form.

A motorboat travels 385 kilometers in 7 hours going upstream and 455 kilometers in 5 hours going downstream. What is the rate of the boat in still water and what is the rate of the current?
Answer:
Rate of the boat in still water 73 mi/hr
Rate of the current 18 mi/hr
Step-by-step explanation:
Calculation to determine the rate of the boat in still water and the rate of the current
Let B represent the speed of the boat in still water.
Let S represent the speed of the stream
Speed upstream = B-S.
Speed downstream = B+S.
Using the equation for distance
Distance=Rate * Time
Upstream
(B-S)7 = 385
(B+S)5= 455
Simplify first:
B-S=385/7
B-S = 55
B+S=455/5
B+S = 91
Solve by elimination. Add the two equations.
2B=55+91
2B = 146
B=146/2
B = 73 mi/hr
Substitute this into either equation and solve for S.
B+S = 91
73+S = 91
S=91-73
S = 18 mi/hr
Therefore the rate of the boat in still water is 73 mi/hr and the rate of the current is 18 mi/hr

AB has points A at (2,−5) and B at (5,−3).
AB iis reflected across the y-axis and then translated 3 units right. What are the coordinates of the endpoints of the image A′B'?
9514 1404 393
Answer:
A'(1, -5)B'(-2, -3)Step-by-step explanation:
Reflection over the y-axis and translation 3 right is modeled by the transformation ...
(x, y) ⇒ (-x +3, y)
Then the image end points are ...
A(2, -5) ⇒ A'(-2+3, -5) = A'(1, -5)
B(5, -3) ⇒ B'(-5+3, -3) = B'(-2, -3)
_____
In the attached figure, the reflection is shown as A'B' in light purple. The line after the final translation is shown as A"B" in blue.

in a certain lake 30% of the fish are thrown back because they are too small. Consider catching 20 fish from the lake. Assume that the fish you caught can be considered a random sample from the very large number of fish in the lake. does this represent a binomial setting
Answer:
Binomial probability distribution concept & application, example
Step-by-step explanation:
Yes, this represents a binomial setting. As, it is used for finding probability of - particular number of success outcomes , from repetitive or multiple events.
Here
Success {Event P} ie small fish, with prob = 30% = 0.3 .Failure {Event Q} ie large fish, with prob = 70% = 0.7Number of trials = 20. Let r be number of small fishes out of 20 fishes.Binomial probability = N c r . (P)^r . (Q)^ (n-r)
Ex : P( 5 small fish out of 20) = 20c5 (0.30)^5 (0.70)^15

Is 0.725 greater then 0.75 decimals
Answer:
0.75 is the larger number
Step-by-step explanation:
If you shorten 0.725, it is 0.72 vs 0.75, making 0.75 the larger number.
Answer:
Nope
Step-by-step explanation:
Think of it like this:
forget the 5 in the THOUSANDTHS place because thats basically, well you can think of it as the ones place now lets look at both of their HUNDREDTHS place.
0.72 and 0.75 which one do you think is greater now? Obviously the 0.75! So just line them up and see if its greater and whatnot.
Five times a number is 80 less than 7 times the number. Find the number.
