The car costs $0.1304 for one mile.

Given, a car costs $3.26 for 25 miles. Let x be the cost of the car per mile.

Then, the cost of the car for one mile is x dollars.

So, the cost of the car for 25 miles is 25x dollars.

As per the given data, the cost of the car for 25 miles is 3.26 dollars.

Therefore, we get the equation as:

25x = 3.26 On dividing both sides by 25, we get x = 0.1304 dollars. Thus, the car costs $0.1304 for one mile.

We have to find the cost of the car for one mile.

So, let x be the cost of the car per mile. Then, the cost of the car for one mile is x dollars.

The cost of the car for 25 miles is 25x dollars.

As per the given data, the cost of the car for 25 miles is 3.26 dollars.

25x = 3.26On dividing both sides by 25, we get

Step-by-step explanation:

A) True. Therefore, there should be no systematic bias when probability sampling is done correctly.

When conducting a research study, it is important to ensure that the sample chosen is representative of the population. Probability sampling is a method that aims to achieve this by giving each member of the population an equal chance of being included in the sample.

When this sampling method is done correctly, it minimizes bias and ensures that the sample is truly representative. For example, let's consider a study on the average height of students in a particular school.

If we were to use probability sampling, we would assign a number to each student and then randomly select a certain number of students from that pool. This would give every student an equal chance of being chosen for the sample, eliminating any systematic bias that might arise if we were to select students based on subjective criteria.

Step-by-step explanation:

The equivalent resistance of the system is 5.0 Ω (option a).

When resistors are connected in parallel, the formula to calculate the equivalent resistance is:

1/Req = 1/R1 + 1/R2 + ...

In this case, we have two 4.0 Ω resistors connected in parallel, so the equivalent resistance of the parallel combination is:

1/Req = 1/4.0 Ω + 1/4.0 Ω = 1/2.0 Ω

Now, we have this parallel combination connected in series with a 3.0 Ω resistor. To find the equivalent resistance of the entire system, we add the resistances in series:

Req = 2.0 Ω + 3.0 Ω = 5.0 Ω

There is sufficient data to infer that the valve does not operate as intended at the 0.1 level.

Null hypothesis: H₀ : μ = 7.6

Alternative hypothesis: Hₐ : μ ≠ 7.6

In inferential statistics, the null hypothesis states that two possibilities are equal.

The observed difference is thought to be the sole product of chance, which is the underlying premise.

Statistical tests can be used to calculate the likelihood that the null hypothesis is true.

So,

Null hypothesis: H₀ : μ = 7.6

Alternative hypothesis: Hₐ : μ ≠ 7.6

As the population standard deviation is given when n > 30

So, we'll run the Z test.

Formula: \(z=\frac{x-\mu}{\frac{a}{\sqrt{n}}}\)

Replace the values:

\(\begin{aligned}& z=\frac{7.7-7.6}{\frac{11.6}{\sqrt{160}}} \\& z=2.449\end{aligned}\)

For the p-value, see the z table.

Consequently, p = 0.9927.

The two-tailed nature of the test So, p = 2(1- 0.9927) = 0.0146

α = 0.1

p value< α

Thus, we disregard the null hypothesis.

Hence, at the 0.1 level, there is enough evidence to conclude that the valve does not function as intended.

Therefore, there is sufficient data to infer that the valve does not operate as intended at the 0.1 level.

The differential equation is not a linear.

The given differential equation is: y′ + x√y = x^2
To determine if this differential equation is linear, we need to check if it can be written in the standard linear form:
y′ + p(x)y = q(x)

Comparing this standard form with the given equation, we can see that the term x√y prevents the equation from being linear. In a linear equation, the dependent variable y and its derivatives (in this case, y′) must appear with a power of 1, and not be inside any non-linear functions like a square root. Since x√y is a non-linear term, the given differential equation is not linear.

The graph that represents the function f(x) = 4[x] is option C.

Option C is the correct answer.

A function is a relationship between inputs where each input is related to exactly one output.

Example:

f(x) = 2x + 1

f(1) = 2 + 1 = 3

f(2) = 2 x 2 + 1 = 4 + 1 = 5

The outputs of the functions are 3 and 5

The inputs of the function are 1 and 2.

We have,

f(x) = 4 [x]

[x] is the greatest integer function.

We see that,

f(0) = 4 [0] = 0

f(0.5) = 4 [0.5] = 4 x 0 = 0

f(x) = 0 for 0 ≤ x < 1

f(1) = 4 [1] = 4

f(1.5) = 4 [1.5] = 4 x 1 = 4

f(x) = 4 for 1 ≤ x < 2

f(2) = 4 [2] = 4 x 2 = 8

f(2.5) = 4 [2.5] = 4 x 2 = 8

f(x) = 8 for 2 ≤ x < 2

Thus,

The graph on option C has the required coordinates.

The car was traveling at approximately 40 ft/s when the brakes were first applied.

To find the initial velocity of the car when the brakes were first applied, we can use the kinematic equation:

v^2 = u^2 + 2as

where:

v = final velocity (0 ft/s, as the car comes to a stop)

u = initial velocity (what we want to find)

a = acceleration (deceleration due to braking, -16 ft/s^2)

s = distance (skid marks, 200 ft)

Rearranging the equation, we have:

u^2 = v^2 - 2as

Substituting the given values, we get:

u^2 = 0^2 - 2(-16 ft/s^2)(200 ft)

u^2 = 6400 ft^2/s^2

Taking the square root of both sides, we find:

u = ±80 ft/s

Since we are looking for the initial velocity, we discard the negative value as it represents the opposite direction of motion. Therefore, the car was traveling at approximately 80 ft/s when the brakes were first applied.

Note: It's important to ensure consistent units throughout the calculations, and in this case, we used the unit of feet per second (ft/s) for velocity and feet (ft) for distance.

The value of dimensions of a triangular prism a = 5m, dimension a = 15m and dimension c = 9m.

A prism is a solid form that is enclosed by plane faces on all of its sides. A prism has two different kinds of faces. Bases refer to the identical top and bottom faces. The name "prism" refers to the form of these bases. For instance, a prism is referred to be a triangular prism if its base is triangular.

The faces of a prism that are not the top and bottom are referred to as its lateral faces. The class of parallelograms also includes all the lateral faces, all of which are identical to one another.

To find the dimensions of a, b and c, we first open all  the faces of prism in first figure, than we compare it with second figure, we find that,

In a linear grammar, for all productions, there is at most one variable on the left side of any production. This means that each production consists of a single nonterminal symbol and a string of terminal symbols.

For instance, consider the following linear grammar:
S → aSb | ε
This grammar is linear because each production has only one nonterminal symbol on the left-hand side. The first production has S on the left-hand side, and it generates a string of terminal symbols (a and b) by concatenating them with another instance of S.

The second production has ε (the empty string) on the left-hand side, indicating that S can also generate the empty string.A linear grammar is a type of formal grammar that generates a language consisting of a set of strings that can be generated by a finite set of production rules. In a linear grammar, all productions have at most one nonterminal symbol on the left-hand side.

This makes the grammar easier to analyze and manipulate than other types of grammars, such as context-free or context-sensitive grammars.

The given expression is (5 - 3)³ ÷ 2. First, we simplify the expression within the parentheses: 5 - 3 = 2. Substituting 2 for (5 - 3) in the expression, we get 2³ ÷ 2. Now, we evaluate 2³, which is 8. So, the expression simplifies to 8 ÷ 2 = 4.

To evaluate the given expression, we first need to simplify the expression within the parentheses using the order of operations or BODMAS rule (Brackets, Order, Division, Multiplication, Addition, and Subtraction).

In this case, we have only one set of parentheses, which contains a subtraction operation between 5 and 3. So, we perform the subtraction and replace (5 - 3) with 2.

Now, we have (2)³ ÷ 2.

Next, we evaluate 2³, which gives us 8.

Finally, we divide 8 by 2 to get the final answer of 4.

Therefore, the expression (5 - 3)³ ÷ 2 simplifies to 4.

The probability that the obstetrician has delivered no child with polydactyly is 0.8187.

To find the probability that the obstetrician has delivered no child with polydactyly, we can use the formula:

P(no polydactyly) = \((1 - P(polydactyly))^{number of births}\)

First, we need to find the probability of a child having polydactyly. This is given as 1 in every 500, which can be expressed as a decimal: 1/500 = 0.002.

Next, we find the probability of a child not having polydactyly: 1 - 0.002 = 0.998.

Now, we can find the probability of the obstetrician delivering no child with polydactyly in 100 unrelated and independent births by raising the probability of no polydactyly to the power of the number of births (100):

P(no polydactyly in 100 births) = (0.998)¹⁰⁰ ≈ 0.8187

So, the probability that the obstetrician has delivered no child with polydactyly is approximately 0.8187.
