the ratio of oak trees to maple trees in John's neighborhood is 3 to 5. using the same ratio, if the town plants 15 oak trees in the park, how many maple trees should they plan? Use equivalent ratios to solve. be sure to include units in each ratio.
Answer:
15 to 25
Step-by-step explanation:
For every 3 oak trees there’s 5 maple. So then you have 3 to 5 so add 3 more oak trees and 5 more maple then it would be 6 to 10 then so on so. From the beginning is 3 to 5, 6 to 10, 9 to 15, 12 to 20, 15 to 25

A satellite circles the earth in such a manner that it is y miles from the equator (north or south, height from the surface not considered) t minutes after its launch, where y is given by the equation below.
(picture)
At what times t in the interval , the first 4 hr, is the satellite mi north of the equator?
9514 1404 393
Answer:
t ∈ {19, 85, 109, 175, 199}
or
t ∈ {40, 64, 130, 154, 220}
Step-by-step explanation:
A graphing calculator relieves the tedium of solving for t. The attachments show the times the satellite is 4000 miles from the equator. Since y may be either north or south, the satellite may be 4000 north of the equator for y = 4000 or for y = -4000.
__
If y is miles north of the equator, then ...
4000 = 6000cos(z) . . . . . where z=(π/45)(t-7)
z = arccos(4000/6000) ≈ 0.84107 radians
There is another solution at 2π -0.84107 radians, about 5.44212 radians
The corresponding time values are ...
t = 7 +(45/π)(z) ≈ 19.047 and 84.953 . . . . minutes
The period of the function is 90 minutes, the times will be the above times and at 90-minute intervals after each.
The satellite is 4000 miles north of the equator at ...
t ≈ 19, 85, 109, 175, 199 . . . minutes after launch
__
The solution is similar if y represents miles south of the equator. Then we have ...
-4000 = 6000cos(z)
z = arccos(-4000/6000) ≈ 2.30052 radians (and 3.98266 radians)
The corresponding time values are ...
t = 7 +(45/π)(z) ≈ 39.952 and 64.047 . . . . minutes
Again, considering the period, the satellite is 4000 miles north of the equator at ...
t ≈ 40, 64, 130, 154, 220 . . . minutes after launch
_____
Additional comment
We might usually think of y as being positive in the northerly direction. However, in this age of political correctness and bias sensitivity, we have to consider that "y is north or south" means exactly that. So, we have also shown the solutions when y is positive south of the equator.
Usually, we prefer that the variables are defined unambiguously.

Which values are solutions to x<16?
Answer:
Option D.
x can take values from 15downwards. It can't be 16 because the expression clearly states that x is less than 16. So x can take value from any number below 16.

Which statements correctly describe the graph of the function f(x) = x3 – 2x2 - 19x + 20? Select three options.
As the x-values increase, the y-values always increase.
As x approaches negative infinity, y approaches negative infinity.
O The domain of the function is all real numbers.
The range of the function is y > 20.
The graph has a positive y-intercept.
Answer:
See below for answers and explanations (along with a graph for reference)
Step-by-step explanation:
A is true because the end behavior shows that as x gets larger, y also gets larger
B isn't true because that is an incorrect interpretation of the end behavior while the statement itself is true.
Any real value of x can be defined on the graph with an output, therefore C is also correct.
D is not true because that would contradict option C which we said was right since the domain and range are both all real numbers.
E is true because the y-intercept of the graph is (0,20) which is positive (marked in purple)
Answer:
B. As x approaches negative infinity, y approaches negative infinity.
C. The domain of the function is all real numbers.
E. The graph has a positive y-intercept.

About 26% of movies coming out of Hollywood are comedies, Warner Bros has been the lead studio for about 13% of recent movies, and about 3% of recent movies are comedies from Warner Bros. Let C denote the event a movie is a comedy and W denote the event a movie is produced by Warner Bros.
Required:
a. What is the probability that a movie is either a comedy or produced by Warner Bros?
b. What is the probability that a Warner Bros movie is a comedy?
c. What is the probability that a comedy has Warner Bros as its producer?
Answer:
a. 0.36 = 36% probability that a movie is either a comedy or produced by Warner Bros.
b. 0.2308 = 23.08% probability that a Warner Bros movie is a comedy
c. 0.1154 = 11.54% probability that a comedy has Warner Bros as its producer
Step-by-step explanation:
Conditional Probability
We use the conditional probability formula to solve this question. It is
[tex]P(B|A) = \frac{P(A \cap B)}{P(A)}[/tex]
In which
P(B|A) is the probability of event B happening, given that A happened.
[tex]P(A \cap B)[/tex] is the probability of both A and B happening.
P(A) is the probability of A happening.
a. What is the probability that a movie is either a comedy or produced by Warner Bros?
We solve this question treating these events as Venn sets.
I am going to say that:
Set A: Movie is a comedy.
Set B: Movie is produced by Warner Bros.
26% of movies coming out of Hollywood are comedies
This means that[tex]P(A) = 0.26[/tex]
Warner Bros has been the lead studio for about 13% of recent movies
This means that [tex]P(B) = 0.13[/tex]
3% of recent movies are comedies from Warner Bros.
This means that [tex]P(A \cap B) = 0.03[/tex]
The desired probability is:
[tex]P(A \cup B) = P(A) + P(B) - P(A \cap B) = 0.26 + 0.13 - 0.03 = 0.36[/tex]
0.36 = 36% probability that a movie is either a comedy or produced by Warner Bros.
b. What is the probability that a Warner Bros movie is a comedy?
Conditional probability, in which
Event A: Produced by Warner Bros
Event B: Comedy
Warner Bros has been the lead studio for about 13% of recent movies
This means that [tex]P(A) = 0.13[/tex]
3% of recent movies are comedies from Warner Bros.
This means that [tex]P(A \cap B) = 0.03[/tex]
The desired probability is:
[tex]P(B|A) = \frac{P(A \cap B)}{P(A)} = \frac{0.03}{0.13} = 0.2308[/tex]
0.2308 = 23.08% probability that a Warner Bros movie is a comedy.
c. What is the probability that a comedy has Warner Bros as its producer?
Now,
Event A: Comedy
Event B: Warner Bros as its producer.
About 26% of movies coming out of Hollywood are comedies
This means that [tex]P(A) = 0.26[/tex]
3% of recent movies are comedies from Warner Bros.
This means that [tex]P(A \cap B) = 0.03[/tex]
The desired probability is:
[tex]P(B|A) = \frac{P(A \cap B)}{P(A)} = \frac{0.03}{0.26} = 0.1154[/tex]
0.1154 = 11.54% probability that a comedy has Warner Bros as its producer

The owner of a pizzeria wishes to build a model relating revenues to advertising expenditures into three categories. which independent variable is the least significant in this regression relationship?
Answer:
Newspaper
Step-by-step explanation:
The level or degree of significance of independent variables used in a multiple regression analysis is usually measured by comparing the values of the slope Coefficient of each independent variable. From the result of the multiple regression analysis attached. The slope Coefficient of each independent variable is :
Television = 2.38 ; Newspaper = 1.45 and Mail = 1.82.
This slope values are the rate at which the dependent variable changes per unit increase in each of the independent variable.
Newapaper has the least slope Coefficient value of the 3 independent variables and hence will have the least significant effect on the value of revenue.

by how much is the product of 9/5 and 33/4 greater than 5
Answer:
The product of 9/5 and 33/4 is 9.85 units larger than 5.
Step-by-step explanation:
To determine by how much is the product of 9/5 and 33/4 greater than 5, the following calculations must be performed:
((9/5) x (33/4)) - 5 = X
(1.8 x 8.25) - 5 = X
14.85 - 5 = X
9.85 = X
Therefore, the product of 9/5 and 33/4 is 9.85 units larger than 5.

Answer: Scalene and isosceles
Step-by-step explanation:
Identify the distance between the points (9,7,3) and (5,3,2), and identify the midpoint of the segment for which these are the endpoints. Round to the nearest tenth, if necessary.
Using it's formula, it is found that the distance between the two points is of 5.7 units. Additionally, the midpoint is (7, 5, 2.5).
What is the distance between two points?Suppose that we have two points, [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex]. The distance between them is given by:
[tex]D = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
In this problem, the points are (9,7,3) and (5,3,2), hence:
[tex]D = \sqrt{(9 - 5)^2 + (7 - 3)^2 + (3 - 2)^2} = 5.7[/tex]
The distance between the two points is of 5.7 units.
What is the midpoint?The midpoint is the mean of the coordinates, hence:
xM = (9 + 5)/2 = 7.yM = (7 + 3)/2 = 5.zM = (3 + 2)/2 = 2.5.The midpoint is (7, 5, 2.5).

Answer:
S"(-17, 13)
Step-by-step explanation:
Since it's reflected across the y-axis, the y value stays the same and the x value changes to a negative. If it were reflected across the x-axis then the x value you stay the same and the y value would change to a negative. Since it's a reflection, meaning it's just "mirrored" across a given point, the numbers stay the same regardless.
