Answer:
34 people. (extremely sorry if this is wrong! please tell me if it is.)
Step-by-step explanation:
197 people were in the survey. First we can subtract 57 from 197 because 57 people dont like cats or dogs.
197-57 = 140
and to find the number of people that chose cats but not dogs, we subtract 106 from 140 which leaves us with 34 people.

The 5/12 cups of dog food are recommended for a 25-pound adult dog
Step-by-step explanation:
Given:
The relationship between the weight of the adult dog (X) and the amount of dog food in cups (Y) is proportional.
To find:
Dog food for the 25-pound adult dog
Solution:
The weight of the adult dog (X) is proportional to the amount of dog food in cups are proportional.
[tex]X\propto Y\\\text{The equation for the relationship will be given as :}\\X=kY\\k=\frac{X}{Y}= Constant[/tex]
From the table given, we can calculate the value of the constant k.
[tex]k=\frac{10}{\frac{1}{6}}=\frac{40}{\frac{2}{3}}=\frac{50}{\frac{5}{6}}=\frac{100}{1\frac{2}{3}}\\k=\frac{10}{\frac{1}{6}}=\frac{40}{\frac{2}{3}}=\frac{50}{\frac{5}{6}}=\frac{100}{\frac{5}{3}}\\k=\frac{60}{1}=\frac{40\times 3}{2}=\frac{50\times 6}{50}=\frac{100\times 3}{5}\\k=60[/tex]
Let the dog food recommended for the 25-pound adult dog be y.
Weight of the dog = x = 25 pounds
Cups of dog food recommended = y
k = 60
Using the equation for the given relationship:
[tex]25=60\times y\\y=\frac{25}{60}=\frac{5}{12}[/tex]
The 5/12 cups of dog food are recommended for a 25-pound adult dog.

Need Help!!!!!!!!!!!!!!Find the outer perimeter of this figure. Round your answer to the nearest hundredth.
Answer:
The perimeter of the figure is 14.71 ft
Step-by-step explanation:
The outer perimeter of the figure is the sum of the boundary dimensions.
The missing outer dimension is the length of the arc or half circumference.
Length of arc formula/half circumference = 1/2 πr = 1/2 x 3.14 x 3 ft = 4.71 ft
The other dimensions are 5ft and 5ft.
Therefore, the outer perimeter of the figure is:
4.71 ft + 5 ft + 5 ft = 14.71 ft

An art museum recently discovered that 12% of their paintings had been stolen and replaced with replicas. If a tourist observes 3 different paintings at random, what is the probability that exactly 2 are fakes? Write your answer as a decimal rounded to the nearest thousandth.
We will find that the probability that exactly one is original (or that exactly two are fakes) is 0.038
We know that 12% of the paintings are replicas.
Then if we see a random painting, the probability that it is a replica is 0.12
This means that the probability that a random painting is not a replica, is 1 - 0.12 = 0.88
Now we want to find the probability that exactly two out of 3 paintings are fake.
An easier thing to find is the probability that exactly one of the paintings is original (is exactly the same thing, just another viewpoint).
Let's assume the paintings are ordered, and the first one is the original one.
The probability of this will be:
P = 0.88*0.12*0.12
But we also have the case where the second one is the original, and the case where the third one is the original, so we have 3 possible permutations.
This means that the probability that exactly one is original (or that exactly two are fakes) is:
P = 3*(0.88*0.12*0.12) = 0.038

Find the vertex and length of the latus rectum for the parabola. y=1/6(x-8)^2+6
Step-by-step explanation:
If the parabola has the form
[tex]y = a(x - h)^2 + k[/tex] (vertex form)
then its vertex is located at the point (h, k). Therefore, the vertex of the parabola
[tex]y = \dfrac{1}{6}(x - 8)^2 + 6[/tex]
is located at the point (8, 6).
To find the length of the parabola's latus rectum, we need to find its focal length f. Luckily, since our equation is in vertex form, we can easily find from the focus (or focal point) coordinate, which is
[tex]\text{focus} = (h, k +\frac{1}{4a})[/tex]
where [tex]\frac{1}{4a}[/tex] is called the focal length or distance of the focus from the vertex. So from our equation, we can see that the focal length f is
[tex]f = \dfrac{1}{4(\frac{1}{6})} = \dfrac{3}{2}[/tex]
By definition, the length of the latus rectum is four times the focal length so therefore, its value is
[tex]\text{latus rectum} = 4\left(\dfrac{3}{2}\right) = 6[/tex]

Find the missing probability. P(A)=2/5,P(B|A)=920,P(A∩B)
I think you meant P(B | A) = 9/20.
By definition of conditional probability,
P(B | A) = P(A ∩ B) / P(A)
so that
P(A ∩ B) = P(A) × P(B | A) = 2/5 × 9/20 = 18/100 = 9/50

Answer:
C. 7
Step-by-step explanation:
5,500 divided by 785 = 7.006, which can be rounded to 7.
The number of puzzle will be left over after the last box is full is 5. Therefore, the correct answer is option A.
Given that, a factory worker has 5,500 puzzles to pack into cartons that each hold 785 puzzles.
The number of cartons required = 5500/785
The division is one of the basic arithmetic operations in math in which a larger number is broken down into smaller groups having the same number of items.

[tex]x {}^{3} + \frac{y}{ay} = xy + 9[/tex]
[tex]x {}^{3 } = xy + 9 - \frac{y}{ay} [/tex]
[tex] {x}^{3} - 9 = xy - \frac{y}{ay} [/tex]
[tex] {x}^{3} - 9 = y(x - \frac{1}{a} )[/tex]
