Using this model, the predicted number of owls in year 8 is about - 11. Does
this prediction make sense? Why or why not?
PREVIOUS
Answer:
No, it doesn't make sense, as we cannot have a negative population of owls.
Step-by-step explanation:
Obtaining a the quadratic model :
y = -1,34x2 - 10,75x - 11.3 ; by fitting the data above ;
To obtain the number of owls after 8 years, we have ;
y = -1,34x2 + 10,75x - 11.3
put x = 8 in the equation
y = -1,34(8)^2 + 10.75(8) - 11.3
y = - 85.76 + 86 - 11.3
y = - 11.06
y = - 11
This figure dies not make sense, as we cannot have a negative population of a certain specie such as owls at any given time.
Answer:
No, because you can't have a negative number of owls.

0.088 is more than 0.78, right?
Hi there!

I believe your answer is:
No.

Here’s why:
0.088 can be described as "eighty-eight thousandths". 0.78 can be described as "seventy-eight hundredths."Thousandths has a lesser value than hundredths. 0.088 is less than 0.78, not greater than.»»————- ★ ————-««

4. If y - 2x = 3 and y - x = 1, what are the values of x and y?
y - x = 1.
or, y= 1+x
y - 2x = 3.
=>1+x -2x= 3 (substituting the value of y)
=>-x= 2
=>x= -2
y = -2+1 = -1
Therefore, x = -2 and y = -1
Write the factored form for a polynomial function of degree three that has zeros of 2, -3, and 0
Answer:
x=-b/2a
Step-by-step explanation:
The factored form for a polynomial function of degree three that has zeros of 2, -3, and 0 is x(x-2)(x+3).
What are the zeros of the polynomial function?The zeros of polynomial refer to the values of the variables present in the polynomial equation for which the polynomial equals 0.
Given that, the zeros of polynomial function are 2, -3, and 0.
So, x=2, x=-3, x=0
x-2=0, x+3=0, x=0
Now, polynomial function is x(x-2)(x+3)
Therefore, the factored form for a polynomial function of degree three that has zeros of 2, -3, and 0 is x(x-2)(x+3).

The cost of a large cake at a bakery is $21.00. The cost of a small cake is
$8.25. The bakery also charges a sales tax of 8.25% and a delivery cost of
$10.50 for each order. The following expression represents the cost of an
(1) order
1.0825(21x + 8.25y) + 10.5
What does the term (21x + 8.25y) represent?
A А
the total cost of the order before delivery
the total delivery cost of the order

The width of a rectangle is 3 inches less than its length, and the area is 88 square inches. What are the length and width of the rectangle?
[tex] \large{ \tt{❃ \: EXPLANATION}} : [/tex]
Remember - The formula to find out the area of a rectangle is l × w where l = length & w = width.Let the length of a rectangle be ' l ' . We're provided - Width ( w ) = l - 3 & area of rectangle ( A ) = 88 square inches. We're asked to find out the length and width of the rectangle. Let's begin ![tex] \large{ \tt{❁ \: SOLUTION}} : [/tex]
[tex] \large{ \tt{♡ \: AREA \: OF \: RECTANGLE \: ( \: A \: ) = \bf l \times w}}[/tex]
Plug the values and then simplify :[tex] \large{ \text{⟶ \: 88 = l(l - 3)}}[/tex]
[tex] \large{ \bf{⟶ \: 88 = {l}^{2} - 3 l}}[/tex]
[tex] \large{ \bf{⟶ {l}^{2} - 3l = 88 }}[/tex]
[tex] \large{ \bf{⟶ \: {l}^{2} - 3l - 88 = 0}}[/tex]
[tex] \large{ \bf{ ⟶{l}^{2} - (11 - 8)l - 88 = 0}}[/tex]
[tex] \large{ \bf{⟶ {l}^{2} - 11l + 8l - 88 = 0}}[/tex]
[tex] \large{ \bf{⟶ \: l(l - 11) + 8(l - 11) = 0}}[/tex]
[tex] \large{ \bf{⟶ \: (l - 11)(l + 8) = 0}}[/tex]
Either :[tex] \large{ \bf{⟶ \: l - 11 = 0}} [/tex]
[tex] \large{ \bf{⟶l = 11 \: in}}[/tex]
Or :[tex] \large{ \bf{⟶l + 8 = 0}}[/tex]
[tex] \large{ \bf{⟶l = - 8 \: in}}[/tex]

What is the best definition of the domain of a relation
Answer:
All of the values that can go into a relation or function (input) are called the domain. ... The domain is the set of all first elements of ordered pairs (x-coordinates). The range is the set of all second elements of ordered pairs (y-coordinates). Only the elements "used" by the relation or function constitute the range.

How long would it take to drive 15 miles at a speed of 64 mph?
Answer:
14 minutes and 4 seconds
Step-by-step explanation:
To solve this you need to use the time speed distance formula.
Distance = Speed × Time
Speed = Distance / Time
Time = Distance / Speed
Speed: 64 mile per hour (km/h)
Distance: 15 miles
Time = Distance / Speed
Time = 70 mile / (50 mile/h)
Time = 14 minutes and 4 seconds

Percentage question, show if 435 is 71% of a higher number what is 7% of that higher number found.
Answer:
7%x = 42.88732394377
Step-by-step explanation:
.71x = 435
x = 435/.71
x = 612.676056338
.07x =612.676056338 * .07
.07x = 42.8873239437
7%x = 42.8873239437
The equation of the line that passes through the point (1,5) and is parallel to the linex + 3y =6
Answer:
Y=3x+2
Step-by-step explanation:
first you have to put it in the formula y = mx + c
Y=3-x
in this format c = 0 so there's no intercept
Y=3x+c
The parallel line will have the same gradient but different intercept.
Now we substitute the coordinates(1,5) into the formula.
y = 5
x = 1
5=(3*1)+c
5=3+c
Now we make c the subject.
c=2
So the answer is:Y=3x+2
You are interested in getting an investment portfolio started with any extra money you make from your part time job while also going to school. While flipping through the latest edition of Money magazine, you read an article that of a survey of magazine subscribers, 164 were randomly selected and analyzed. A 95% confidence interval was constructed for the proportion of all subscribers who made money in the previous year in their investments, which was ( 0.6904 , 0.8218 ). What is the correct interpretation of this confidence interval
Answer:
We are 95% confident that the proportion of all Money magazine subscribers that made money in the previous year from their investments is between 0.6904 and 0.8218
Step-by-step explanation:
The confidence interval gives a range of values for which a population proportion will fall based on a given level of confidence, in this case it is 95%. This interval is calculated using the sample proportion. The sample proportion in this case is based on a number of samples examined. The interval we obtain in this case (0.6904; 0.8218) is the estimated range which we expect the population proportion to fall ; with a 95% confidence.
