Answer:
Step-by-step explanation:
$6/(2 DVDs) = $3/DVD, and $8/(4 CDs) = $2/CD
a DVD costs $3
a CD costs $2
Ling bought 4 DVDs and 2 CDs for 4×$3 + 2×$2 = $16.
Pierre bought d DVDs and c CDs for $20.
d is 0, 2, 4, or 6
c = (20-3d)/2
(d,c) = (0,10), (2,7), (4,4), or (6,1)
How can square roots be written so that the radicand has no square factors?
Answer:
You can do this by dividing the radicand by the square number , and multiplying the radical by the root of that number.
e.g.
[tex]\sqrt{96} \\= \sqrt{16 \times 6}\\= 4\sqrt{6}[/tex]

What type of construction is illustrated in the diagram below
Answer:
This is an angle bisector.
Step-by-step explanation:
This is due to the arcs being drawn from point C in a manner to intersect the line segment AB, and the points are then used to find another point by creating arcs, thus creating the angle bisector for the angle ∠ACB.
it's is estimated that each guest at the party will eat 5/8 pounds of chocolate.How. many guest can be served with 10 pounds of chocolate?
Answer: 16
Step-by-step explanation:
Guests = x
5x/8 = 10
x = 16
16 guests can be served with 10 pounds of chocolate when estimated each guest at the party eat 5/8 pounds of chocolate.
it's is estimated that each guest at the party will eat 5/8 pounds of chocolate. We need to find number of guests can be served with 10 pounds of chocolate
What is Equation?
Two expressions with an equal sign is called as equation.
When it's is estimated that each guest at the party will eat 5/8 pounds of chocolate. We need to find number of guests can be served with 10 pounds of chocolate.
we need to divide 10 by 5/8 to find the answer
10/(5/8)=10*8/5=80/5=16
Therefore 16 Guests can be served with 10 pounds of chocolate.

"5 times as many bears"
A would be 5 more bears than,
B would be 5 times more bears than,
C would be 5 times less bears than, and
D would be 5 less bears than.
Answer:
B. b = 23 * 5
Step-by-step explanation:
Yellow Park: 23 bears
Green Park: 5 times as many bears as in Yellow Park

Driving 65 mph, it takes Alicia 3 hours to reach the airport to go on a vacation. It then takes her 4 hours to get to her destination with the jet traveling at a speed of 400 mph. How many miles does Alicia travel to get to her destination?
Answer:
1,795 mi. traveled in total
Step-by-step explanation:
3 × 65 = 195 mi. driven by car
4 × 400 = 1,600 mi. flown by jet
1,600 + 195 = 1,795 mi. traveled in total.
6 Item 6 For a specific species of fish in a pond, a wildlife biologist wants to build a regression equation to predict the weight of a fish based on its length. The biologist collects a random sample of this species of fish and finds that the lengths vary from 0.75 to 1.35 inches. The biologist uses the data from the sample to create a single linear regression model. Would it be appropriate to use this model to predict the weight of a fish of this species that is 3 inches long
Answer:
Yes, because the regression equation is based on the random sample.
Step-by-step explanation:
A simple linear regression model that describes the relationship between X and Y takes the form
Yi= ∝ + βXi + εi or
Y i= U(y.x) + εi
where εi's are the random errors. The random errors εi's are assumed to be independent of Xi and normally distributed with E(εi)= 0 and Var (εi)= σ²(y.x) , a constant for all Xi. These assumptions imply that Yi also have a common variance σ²(y.x) , as the only random element in the is εi.
The estimated regression line Y= a+ bX is also the predictor of Yi= ∝ + βXi+ εi
. That is Y^ can also be used to predict an individual value Y0 of Yi rather than a mean value, corresponding to the given X0. To draw the inferences about Y0 we need to know it mean and variance.
At 1:00 a.m., the temperature is 58º. At 9:00 a.m., the temperature is 76º. Find the rate of change in degrees per hour during this time.
Answer:
1 AM = 58 Degrees
9 AM = 76 Degrees
Difference of temperate between the times:
18 Degrees
Divide every hour that passes by the total difference of temperate, which the hours are: 2, 3, 4, 5, 6, 7, 8, 9
18 / 8 = 2.25
Which means, the rate of change in degrees per hour is 2.25 degrees.

You deposit $200 in an account that earns 4% simple interest. How much interest did you earn in 3 years? (Hint: I = prt)
Answer:
$24.
Step-by-step explanation:
Given that I deposited $ 200 in an account that earns 4% simple interest annually, to determine how much interest did I earn in 3 years, the following calculation must be performed:
((200 x 4/100) x 3) = X
((800/100) x 3) = X
(8 x 3) = X
24 = X
Thus, after 3 years of investment I will have earned $ 24 in interest.

Traveling Salesperson Suppose you are a salesperson who must visit the following 23 cities: Dallas, Tampa, Orlando, Fairbanks, Seattle, Detroit, Chicago, Houston, Arlington, Grand Rapids, Urbana, San Diego, Aspen, Little Rock, Tuscaloosa, Honolulu, New York, Ithaca, Charlottesville, Lynchville, Raleigh, Anchorage, and Los Angeles. Leave all your answers in factorial form.
a. How many possible itineraries are there that visit each city exactly once?
b. Repeat part (a) in the event that the first five stops have already been determined.
c. Repeat part (a) in the event that your itinerary must include the sequence Anchorage, Fairbanks, Seattle, Chicago, and Detroit, in that order.
Answer:
1. 23!
2. 18!
3. 19!
Step-by-step explanation:
1.
We start by the order that we were given. Dallas is the first City with los Angeles being the last.. a total of 23 states.
Dallas can be placed in any of the 23 positions.
Tampa can be placed in any of the remaining 22 positions and so on.
Such that we have
Total number of ways = 23x22x21...x1 ways
= 23!
2. If first 5 cities have been determined,
23-5 = 18 cities
We can arrange in (23-5)! Ways
= 18!
3. We consider these 5 cities to be 1 unit, so we have to arrange the remaining 18 cities plus this single unit.
Total number of ways = (18+1)!
= 19!

Second row: 0Third row: 3-2 and 1====================================================
Explanation:
The first column is the list of x values we plug into the function. The second column describes what happens to those x inputs. Namely, we subtract off 2. In the first row, it shows 0-2 after replacing x with 0. This leads to the result of -2 since 0-2 = -2.
In the second row, we have the input x = 2 turn x-2 into 2-2 = 0. So that's why 0 goes in the blank for the second row.
In the third row, we have x-2 = 3-2 = 1. So we'll have 3-2 go in the first blank of row 3, and the value 1 go in the second blank of this same row.

Answer:
y = 4x -19
Step-by-step explanation:
y = 4x + b
first we add the point to the equation and then we solve for b
-3 = 4 ( 4 ) + b
-3 = 16 + b
-16
-19 = b
