The inequality for which the order pair (-5, -7) is a solution will be x + y ≤ 3. Then the correct option is B.
What is inequality?Inequality is defined as an equation that does not contain an equal sign. Inequality is a term that describes a statement's relative size and can be used to compare these two claims.
Let's check all the options, then
A) y ≤ (1/4)x - 1
At (-5, -7), we have
-7 ≤ (1/4)(-5) - 1
-7 ≤ -2.25
This is incorrect.
B) x + y ≤ 3
At (-5, -7), we have
-5 + (-7) ≤ 3
-12 ≤ 3
This is correct.
The inequality for which the order pair (-5, -7) is a solution will be x + y ≤ 3. Then the correct option is B.

In an animal rescue facility are 21 animals.14 cats and 7 dogs. During the day 5 animals were adopted.what is the probabity that 3 cats and 2 dogs were adopted? Review ch 7 on probability
Answers
Answer:
0.3756
Step-by-step explanation:
I believe this is a combinatorics probability problem.
We first figure out in how many ways we can choose 3 cats out of 14 cats
Then we figure out how many ways we can choose 2 dogs out of 7 dogs
The total number of ways to select 3 cats and 2 dogs will be the product of these two
We then figure out in how many ways we can select 5 animals out of a total of 21 animals
The product we computed divided by the above number will give the probability
The number of ways we can choose k items out of n items is given by nCk i.e n Choose k
The formula is rather complicated but almost all calculators should be able to compute this given n and k
Let's deal with the selection of 3 cats from the population of 14 cats
This is given by 14C₃ which works out to 364
Number of ways for selecting 2 dogs from 7 dogs = 7C₂ = 21
Number of ways of selecting 5 animals from 21 = 21C₅ = 20349
The probability of selecting 3 cats and 2 dogs is therefore:
[tex]\dfrac{364 \times 21}{20349} = 0.3756[/tex]
That, I believe is the answer. Please let me know if it is correct and if you need more info.

(iii) the mode, of the distribution.

Answers
a) The dot plot of the data-set is given by the second image shown at the end of the answer.
b - i) The mean of the distribution is of: 1.6 goals.
b - ii) The median of the distribution is of: 1.
b - iii) The mode of the distribution is of: 1 goal.
What are the measures?The mean is given by the sum of all observations of the data-set, hence it is of:
Mean = (0 x 5 + 1 x 6 + 2 x 4 + 3 x 3 + 4 x 1 + 5 x 1)/20 = 1.6.
The median of the distribution is the middle value of the distribution, which is the value of which half the distribution is less than and half is greater than.
Adding in the frequency table given at the end of the answer, it is found that the middle term is of 1, as the sum of the frequencies reaches 10, which is half of the cardinality of 20, at a number of 1.
The mode is the term with the highest absolute frequency, hence it is also of one goal, as it has the highest absolute frequency, which is of 6.
The dot plot gives a dot to each measure for each time that it appears, hence it says the same thing as the table, in a different format.

solve -x+y=6 and 2x+5y=-12 using substitution method
Answers
x=-6 and y=0 are solutions for the equations 2x+5y=-12.
What is Equation?Two or more expressions with an Equal sign is called as Equation.
Given equations,
-x+y=6...(1)
2x+5y=-12 ...(2)
From equation 1
y=6+x
Now put y value in 2
2x+5(6+x)=-12
2x+30+5x=-12
7x+30=-12
Subtract 30 on both sides
7x=-12-30
7x=-42
Divide both sides by 7
x=-6
Now plug in x value in equation 1
-(-6)+y=6
6+y=6
y=0
Hence, x=-6 and y=0 for the equations 2x+5y=-12.

Answers
Answer:
slope intercept form:
y = [tex]\frac{5}{4}[/tex] x - [tex]\frac{7}{2}[/tex]
Step-by-step explanation:
m = 5/4
x = 2 from the point (2,-1)
y = -1 from the point (2,-1)
y = mx + b
-1 = [tex]\frac{5}{4}[/tex] ([tex]\frac{2}{1}[/tex]) + b
-1 = [tex]\frac{10}{4}[/tex] + b
-1 = [tex]\frac{5}{2}[/tex] + b Subtract [tex]\frac{5}{2}[/tex] from both sides
[tex]\frac{-2}{2}[/tex] -+ [tex]\frac{-5}{2}[/tex] = b

Assume that all distributions are normal, the
four population standard deviations are
approximately the same, and the data were
collected independently and randomly. Use a
level of significance of 0.05.
Answers
By using the concept of mean and standard deviation, it can be inferred that
The the drug stays in the system for more than 397 minutes
What is mean and Standard Deviation?
Suppose there is a data set and the average of the data set has to be calculated. To calculate the average of the data set, mean is used
To know about Standard Deviation, it is important to know about Variance
Variance is the sum of the square of deviation from mean.
Square root of the variance gives the standard deviation
Given n = 35,
Population mean = 397
Population Standard Deviation = 18
Here the sample size is large. So the distribution is approximately normal
To test :
Test statistic t =
= 1.97
p value at = 0.0244
Since 0.0244 < 0.05, the null hypothesis is rejected
So the the drug stays in the system for more than 397 minutes

The quadratic function that models the graph on the image is given as follows:

What is the quadratic function?The features of the quadratic equation given from the graph are given as follows:
The vertex.The y-intercept.The equation of a quadratic function with vertex (h,k) is defined as follows:
y = a(x - h)² + k.
In which a is the leading coefficient of the function.
From the graph, the coordinates of the vertex are given as follows:
(1,1).
As the vertex is the turning point of the function.
Hence the parameters h and k have values of:
h = 1, k = 1.
Hence:
y = a(x - 1)² + 1.
The y-intercept of the function is of:
y = 2.
This means that when x = 0, y = 2, hence the leading coefficient a is obtained as follows:
2 = a(0 - 1)² + 1
a = 1.
Hence the equation is of:
y = (x - 1)² - 1.

The expression for the total shaded area is in terms of x is
Area = (x + 5)(x - 3)
How to find the total shaded areaThe top side of the diagram shows that the dimension for the shaded area has length = x + 5
The width of the shaded area is x - 3
Area of a rectangle is given by the formula
Area = Length * width
Area = (x + 5) * (x - 3)
Area = x² - 3x + 5x - 15
