Answer: 60 dogs are male and over 3 years out of total 150 male dogs.
Step-by-step explanation:
Total no. of dogs are 500
Males are 500 x 0.3 = 150
Over 3 years are 150 x 2/5 = 60
Answer:
Total number of dogs: 500
Percent that is male: 30
Over the age of 3: 2/ 5
30 % of 500 = 150
MAKE IT INTO A FRACTION
2= 60
5 = 150
60 of the dogs are male and over 3 years.

Jo estimated the quotient of –41.71 divided by –6.03 by rounding each to the nearest integer. What is Jo’s error? (picture below) Jo should have rounded the dividend to –40. Jo should have rounded the divisor to –6. Jo should have divided –7 by –42. Jo should have divided –7 by –7.
Answer:
Jo should have rounded the divisor to -6.
Explanation:
When rounding, a number with a decimal value below 0.5 rounds down and a number with a decimal value of 0.5 and greater gets rounded up. 0.3 is less than 0.5 which means -6.03 is closer to -6 than -7 and should have been rounded to -6 instead.

Answer:
Function f(x) is positive for the values x ≤ -6 and x ≥ -2 and negative in the interval -6 ≤ x ≤ -2.
Step-by-step explanation:
As given in the graph,
Given function is a quadratic function, f(x) = (x + 2)(x + 6)
With x-intercepts of the function, x = -6 and -2
Graph below the x-axis represents the negative values of the function.
Graph above the x-axis represents the positive values of the function.
Therefore, function f(x) is positive for the values x ≤ -6 and x ≥ -2 and the function is negative in the interval -6 ≤ x ≤ -2.

The quadratic equation is not factorized completely. The given factors are prime factors. Option A is correct.
What is prime factorization ?A mathematical quantity is factorized when it is expressed as multiples of smaller units of closely related quantities.
Factorization is the breakdown of an integer into smaller numbers that, when multiplied together, yield the original, considered number. Factors of those regarded as integers are those who make up an integer.
When all those factors are prime numbers, this is known as prime factorization. In other words, prime factorization expresses an integer in terms of prime multiples.

For the following questions answer independent, dependent, or both. a) This probability causes you to subtract one from the total on the second draw because you don't replace. b) This probability causes you to multiply the probability of the first event by the probability of the second event. c) This probability causes you to leave the total the same on the second draw because you replace.
Answer:
(a)Dependent
(b)Both
(c)Independent
Step-by-step explanation:
a) When selections are made without replacement, the second(next) outcome is dependent of the first(previous) outcome. Therefore, we subtract one from the draw on the total.
Dependent(b)The probability of Event A and Event B is the multiplication of the probability of event A and the probability of event B. Events A and B can either be dependent or independent.
Both(c)When selections are made with replacement, the next outcome is independent of the previous outcome. Therefore, we say that the two events are independent.
IndependentLouis was saving money to purchase a remote-controlled model airplane. The plane cost $48. His grandfather gave him $6 and his mother gave him an allowance of $5 per week. If he saved all of his money, he would have 6+5x dollars after x weeks. How much money would Louis have after 8 weeks, and would it be enough?
Answer:

Choose the correct graph of the following condition.
{(x, y) : x≥2}∩{(x, y) : y≥2}
Answer:
see below
Step-by-step explanation:
{(x, y) : x≥2}∩{(x, y) : y≥2}
First {(x, y) : x≥2}
A solid line at x =2 and shaded to the right
(x, y) : y≥2
A solid line at y =2 and shaded above
∩ means intersection or where they overlap
The green area is where they over lap
These are the equations
Here clearly the lines lie in Q1 and 2 units away from both the axis
B is most suitable because it's intersection means their common or overlapping areaAt which root does the graph of f(x) = (x – 5)3(x + 2)2 touch the x-axis?
The way you can tell if the graph is going to cross the x-axis or just touch the x-axis is by looking at the power of factor
(x-5)^3 has a power of 3 which is an ODD number. An ODD power means that the graph will cross through the x-axis
(x+2)^2 has the power of 2 which is an EVEN number. An Even power means that the graph will touch the x-axis
To find where it will touch the axis set the factor equal to zero and solve .
(x + 2) = 0
Subtract 2 from both sides
x=-2

The vertex of this parabola is at (4,-3). Which of the following could be its
equation?
A. x==3(y - 3)2 + 4
B. X=-3(+4)2-3
C. X=-3(-4) 2-3
D. X=-3(y + 3) - 4
Answer:
Option D.
Step-by-step explanation:
From the given graph it is clear that it is a parabola along to the x-axis.
Vertex form of a parabola along the x-axis is
[tex]x=a(y-k)^2+h[/tex]
where, (h,k) is vertex.
From the graph it is clear that the vertex of the parabola is (4,-3). So, substitute h=4 and k=-3 in the above equation.
[tex]x=a(y-(-3))^2+(4)[/tex]
[tex]x=a(y+3)^2+4[/tex] ...(1)
The graph passing through (1,-2), so substitute x=1 and y=-2 in the above equation.
[tex]1=a(-2+3)^2+4[/tex]
[tex]1-4=a(1)^2[/tex]
[tex]-3=a(1)^2[/tex]
Substitute a=-3 in equation (1).
[tex]x=-3(y+3)^2+4[/tex]
Therefore, the correct option is D.

company to recover an initial investement of $45,000 and earn an additional $15,000 as profit?
The company has to sell
$15,000 as profit.
shaving sets to recover an initial investment of $45,000 and earn an additional
Answer:
The company has to sell 30,000 sets.
Step-by-step explanation:
Cost of each set = $5
Sale of each set = $7
Profit on each set = $7 - $5 = $2
Let
Number of sets = x
Profit on x number of sets = ($2) · x
Recovery of initial investment = $45,000
Additional profit = $15,000
Total Profit desired = $45000 + $15000 =$60,000
Which means that we have to find the number of sets sold, which can earn us a total profit $60,000, from which $45000 are the recovery of initial investment and $15000 are additional profit.
We can conclude that:
Profit on x number of set = Total profit desired
($2) · x = $60,000
x = $60,000 / $2
x = 30,000 sets

c. 13+7=20 20>9
d.10+7=17 17>9
e.8+7=15 15>9
f.22+7=29 29>9 although 29 is greater than 9, we also have to keep in mind that the other 2 sides must also be greater than the other side. so try 7+9= 16. 16 isnt greater than 22 so it can’t be one of the answers.

Which congruence statement correctly compares the two triangles shown? answers: A) ΔBCD ≅ ΔMKL B) ΔCBD ≅ ΔKLM C) ΔDCB ≅ ΔMLK D) ΔBCD ≅ ΔMLK
Answer: A) ΔBCD ≅ ΔMKL
Step-by-step explanation:
In the given picture, it can be seen that
In Δ BCD and ΔMKL
∠B = ∠M
∠C = ∠K
∠D = ∠L
So, corresponding angles are equal.
Also,
segment BD = segment ML
segment DC = segment KL
segment BC = segment MK
So by using SSS (Side-Side-Side) postulate of congruence, we have
ΔBCD ≅ ΔMKL
Hence, the correct option is A) ΔBCD ≅ ΔMKL.
