What fraction of Kaitlins family have green or brown eyes?

The answers are a) (f+g)x = 4x+15, b) 39 and c) the animals adopted in 6 months are 24 and there were already 15 animal at the shelter.

An expression, rule, or law that defines a relationship between one variable (the independent variable) and another variable (the dependent variable) is called a function.

Given that, the function f(x) = 3x + 10 represents the number of animals adopted at one shelter, and the function g(x) = x + 5 represents the number of animals adopted at another shelter, where x is the number of months.

a) (f+g)x = f(x) + g(x)

= 3x+10 + x+5

= 4x+15

∴ (f+g)x = 4x+15

b) (f + g)(6)

Put x = 6 in (f+g)x = 4x+15

∴ (f + g)(6) = 4(6)+15

= 24+15

= 39

c) It means, the animals adopted in 6 months are 24 and there were already 15 animal at the shelter.

Hence, the answers are a) (f+g)x = 4x+15, b) 39 and c) the animals adopted in 6 months are 24 and there were already 15 animal at the shelter.

Answer:

Step-by-step explanation:

Part A: (f + g)(x) = 4x + 15.

My work for Part A:

Step 1: Write the functions without the parentheses: x + 5 + 3x + 10 .

Step 2: Rewrite the function so like terms are next to each other: x + 3x + 5 + 10.

Step 3: Combine like terms: x + 3x = 4x, and 5 + 10 = 15.

Step 4: Write the final function in standard form: (f + g)(x) = 4x + 15.

Part B: (f + g)(6) = 39.

My work for Part B:

Step 1: Write the first function substituting x for 4: f(6) = 6 + 5.

Step 2: Solve the function: f(6) = 6 + 5 = 11.

Step 3: Write the final answer for the first function: f(6) = 11.

Step 4: Write the second function substituting x for 4: g(4) = 3 x 6 + 10.

Step 5: Solve the function: g(4) = 3 x 6 = 18, and 18 + 10 = 28.

Write the final answer for the second function: g(4) = 28.

Step 6: Add the output answers together: 11 + 28 = 39.

Step 7: Write the final output answer for both functions: (f + g)(4) = 39.

Part C: 39 represents the total number of animals adopted at two shelters in 6 months.

X + Y is continuous with density function fx+y(t) = |sx.x(8,6-u)|dxdy.

Let X and Y be jointly continuous random variables with joint density function fx,y(x,y). The density function of the sum of X and Y, X + Y, is given by the convolution of fx,y(x,y) and is denoted by fx+y(t). The convolution of fx,y(x,y) is calculated as follows:

fx+y(t) = ∫∫infinityfX,Y(x,y)dydx

= ∫∫∞fX,Y(x,y)dxdy

= ∫∫∞fX,Y(x,y)sx.(x(8,6-u))dxdy

= ∫∫∞|sx.x(8,6-u)|dxdy

Hence, X + Y is continuous with density function fx+y(t) = |sx.x(8,6-u)|dxdy.

The correct option Cluster random sample.

In cluster random sampling, at first the population is divided into several small non-overlapping sub-populations and these sub-populations are called clusters.

The size of the cluster may or may not be equal.

Units within the cluster should be as heterogeneous as possible, i.e. one cluster could represent the population, and units between the clusters should be homogeneous.

Then simple random sampling is used to select some sample cluster and all the units of the selected cluster are taken as sample units.

Cluster sampling can be more cost-effective than simple random sampling, especially if the population is dispersed across a large geographical area.

However, cluster sampling methods tend to be less efficient than either simple random sampling methods or stratified sampling methods and often require a larger sample size.

The entire population: here all customers are divided into several clusters: here 35 rides. Sample of clusters: here 5 rides are selected and all items in the selected 5 clusters are included in the sample.

The value of x and y from the given right triangle are 13 units and 18.38 units respectively.

The sides and angles of a right-angled triangle are dealt with in Trigonometry. The ratios of acute angles are called trigonometric ratios of angles. The six trigonometric ratios are sine (sin), cosine (cos), tangent (tan), cotangent (cot), cosecant (cosec), and secant (sec).

We know that, cosθ= Base/Hypotenuse and sinθ= Perpendicular/Hypotenuse

Now, cos45°= 13/y

0.7071= 13/y

y =13/0.7071

y =18.38 units

Here, sin45°= x/y

0.7071=x/18.38

x= 18.38×0.7071

x= 12.99

x≈13 units

Therefore, the value of x and y are 13 units and 18.38 units respectively.

Systematic sampling involves selecting every nth item from a list, potentially with bias and non-random results, so choose carefully.

The method used to choose the sample in this study is called "systematic sampling". This involves selecting a starting point (in this case using a random number generator) and then selecting every nth item (in this case, every 3rd person) from a list to form the sample. This type of sampling can introduce biases in the sample if the list has some pattern or structure, so it's important to be aware of these potential issues when using this method.

In systematic sampling, the selection of each member of the sample is based on a fixed and systematic rule. The advantage of this method is that it is easy to implement and cost-effective. The disadvantage is that if the list has any pattern or structure, such as alternation or clustering, the sample may not be representative of the population. It's important to carefully consider the list and choose an appropriate starting point and interval to reduce the potential for bias.

It's also worth noting that systematic sampling may not result in a random sample, as the sample members may not be independent of each other. This can have implications for the validity of inferences made from the sample to the population. Therefore, it's important to carefully consider the properties of the population and the goals of the study when choosing a sampling method.

The number and lengths of disjoint cycles of the function f(a) (where f is given by the action of a group g of order n on itself via translation) depend on the specific group and the specific element a being acted upon.

If g is a finite group, then the function f(a) has precisely n disjoint cycles, each of length a power of a prime dividing n. The factorization of n into primes determines the number of cycles of each length.

If n is a prime number, then g is a cyclic group and f(a) has precisely one cycle of length n.

If n is a composite number, then f(a) will have distinct length cycles.

The cycle lengths correspond to the divisors of n, and the number of cycles of each length corresponds to the number of times that divisor appears in the factorization of n.
