Answer:
D. The flow rate of the large tank is -20 gal/min, and the flow rate of the small tank is 20 gal/min.
Step-by-step explanation:
Flow rate = [tex]\frac{gallons of water}{minute}[/tex]
flow rate of water in the big tank = [tex]\frac{300}{5}[/tex]
= 60 gallons/minute
flow rate in the smaller tank = [tex]\frac{200}{5}[/tex]
= 40 gallons/minute
The difference in flow rate between the tanks = 60 - 40
= 20 gallons/minute
Since the two tanks have the same amount of water after the given time, then the volume of water in the large tank decrease; while the volume of water in the small tank increased.
Therefore, the flow rate of the large tank is -20 gal/min, and the flow rate of the small tank is 20 gal/min. This shows that option D is correct.

A quadratic equation contains at least one term that is squared. The standard form is ax² + bx + c = 0 with a, b, and c being constants, or numerical coefficients, and x is an unknown variable.
Mr. Waxman is helping with deliveries for a shipping company. The graph shows a linear model for his delivery times on different days.
(A) Identify two points on the line and write the coordinate pairs below.
(B) Use your two points to find the slope, and make sure to show your work.
(C) Use your slope from Part B and find the equation of the line in point-slope form. Show your work and work through the steps to transform the equation from point-slope form into slope-intercept form.
(D) Based on the equation you found in Part C, predict how long it take Mr. Waxman to deliver his packages on Day 0. Approximately how much did his delivery time decrease per day?
Answer: a- (7,7) (4,19) b- m=-12/3=-4/1=-4 c- y=4x+35 d- 48min, it increases by 12min a day

Mr. Waxman's delivery is an illustration of a linear function.
(a) Two points on the graph
The points are: (4,19) and (6,11)
(b) The slope of the graph
The slope (m) is calculated as:
[tex]\mathbf{m = \frac{y_2 - y_1}{x_2 - x_1}}[/tex]
So, we have:
[tex]\mathbf{m = \frac{11 - 19}{6- 4}}[/tex]
[tex]\mathbf{m = \frac{-8}{2}}[/tex]
[tex]\mathbf{m = -4}[/tex]
The slope of the graph is -4
(c) The equation of the graph
In point-slope form, we have:
[tex]\mathbf{y -y_1 = m(x - x_1)}[/tex]
So, we have:
[tex]\mathbf{y -4 = -4(x -19)}[/tex]
In slope intercept form, we have:
[tex]\mathbf{y = -4(x -19) + 4}[/tex]
Open brackets
[tex]\mathbf{y = -4x +76 + 4}[/tex]
[tex]\mathbf{y = -4x +80}[/tex]
The equation of the graph is: [tex]\mathbf{y = -4x +80}[/tex]
(d) The value of the function at day 0
This means that x = 0
So, we have:
[tex]\mathbf{y = -4(0) +80}[/tex]
[tex]\mathbf{y = 0 +80}[/tex]
[tex]\mathbf{y = 80}[/tex]
Hence, it will take 80 minutes to deliver the package on day 0

Given two points are :-
( -1 , 3)( 0 , -5)So , we know Two point form into equⁿ using a formula , which is
[tex]\boxed{\purple{\bf{\dag y - y_1 = \dfrac{y_2-y_1}{x_2-x_1}(x-x_1)}}}[/tex]
So, on substituting respective values ,

Step-by-step explanation:
Luis and Roberto are donating some of their baseball cards to the library. Luis started with 50
cards and gave away X number of them. Roberto started with 80 cards and gave away 3 times as
many as Luis had given away.
If they both now have the same number of baseball cards, how many baseball cards did Roberto
give away?
Answer:
X=15
Step-by-step explanation:
50−x=80−3x
Step 1: Simplify both sides of the equation.
50−x=80−3x
50+−x=80+−3x
−x+50=−3x+80
Step 2: Add 3x to both sides.
−x+50+3x=−3x+80+3x
2x+50=80
Step 3: Subtract 50 from both sides.
2x+50−50=80−50
2x=30
Step 4: Divide both sides by 2.
2x \2 = 30 \2

According to a survey, 74% of households said that they have never purchased organic fruits or vegetables. Suppose that this result is true for the current population of households. a. Let x be a binomial random variable that denotes the number of households in a random sample of 10 who have never purchased organic fruits or vegetables. What are the possible values that x can assume? Integers to . b. Find to 3 decimal places the probability that exactly 6 households in a random sample of 10 will say that they have never purchased organic fruits or vegetables. Use the binomial probability distribution formula. Probability
Answer:
a
The possible value of x is 0, 1 ,2,3,4,5,6,7,8,9,10
b
[tex]P(X = 6) = 0.158 [/tex]
Step-by-step explanation:
From the question we are told that
The proportion that stated that they have not purchased organic fruits or vegetables is [tex]p =0.74[/tex]
The sample size is n = 10
The possible value x can take is 0, 1 ,2,3,4,5,6,7,8,9,10
Generally the probability that exactly 6 households in a random sample of 10 will say that they have never purchased organic fruits or vegetables is mathematically represented as
[tex]P(X = 6) = ^nC_6 * p^{6}* (1-p)^{n-6}[/tex]
Here C denotes combination
So
[tex]P(X = 6) = ^{10}6 * (0.74)^{6}* (1-0.74)^{10-6}[/tex]
=> [tex]P(X = 6) = 0.158 [/tex]
Solve for b.

Answer:
A. no, the sale price is about 60% of $65 or $39. Because $38 is less than $39, you do not have enough money.
Step-by-step explanation:
Given parameters:
Discount on sales = 40%
Amount with me = $38
Original sales price = $65.99
Unknown:
Will you have enough money to buy the item = ?
Solution:
To solve this problem, let us find the discount amount on the selling price;
= [tex]\frac{40}{100}[/tex] x 65.99
= $26.39
So, the price of the item now = Original sales price - discount amount
= $65.99 - $26.39
= $39.6
$39.6 can also be derived from 60% of $65.99
This amount is more than amount at hand.
