Answer:

your right it is a rational number

The value of c 0.097 can satisfy the probability condition p(z ≤ c) = 0.52.

We need to find a value of c such that the probability of a standard normal random variable, Z, being less than or equal to c is 0.52, i.e., P(Z ≤ c) = 0.52.

We can use a standard normal table or a calculator to find the value of c that corresponds to a probability of 0.52. For example, using a calculator or a table, we can find that the 0.52 percentile of the standard normal distribution is approximately 0.097.

Therefore, we have:

P(Z ≤ c) = 0.52

c = 0.097 (from the standard normal table or calculator)

So, the value of c that satisfies the given probability condition is approximately 0.097.

Step-by-step explanation:

The required Distribution, selection and probability is X to U(4,11), x to N (7.5, 0.3415) and 0.87932 respectively.  

(a) Distribution of X is uniform distribution  X to U(4,11).

(b) Sample size (n) = 35, distribution of mean would be moderate with value = (4+11)/2 = 7.5

Standard deviation = √ [(11-4)^2/(12*35] = 0.3415
Now
x to N (7.5, 0.3415)

(c) We have to find probability that the average of 35 numbers will be less than 7.9.

P(x < 7.9) = P(x < 7.9; 7.5; 0.3415)
Z = (7.9 -7.5)/0.3415
Z = 1.1713
P(x< 7.9)= P(Z < 1.1713)= 0.87932.

Thus, The required Distribution, selection and probability is X to U(4,11), x to N (7.5, 0.3415) and 0.87932 respectively.

The given statement , police departments continue to control the sole statistical data available to measure homicide rates in the united states is false.

Domestic disagreements, interpersonal violence, violent fights over land resources, intergang violence over turf or control, and predatory violence and murders by armed organizations are all examples of intentional homicides.

Intentional homicide does not cover all intentional killing; the distinction is usually in the manner in which the killing is carried out.

Homicide is typically committed by individuals or small groups, but killing in armed conflict is typically performed by highly cohesive organisations of up to several hundred members and is thus typically omitted.

Answer:

Big O notation is used to describe the performance or complexity of an algorithm. Here are four rules to keep in mind when working with Big O notation:

Coefficients do not matter: When analyzing the performance of an algorithm, the coefficients of the terms in the Big O expression are not important. For example, O(2n) and O(n) are equivalent.

Ignore lower order terms: When analyzing the performance of an algorithm, only the highest order term is important. For example, O(n^2 + n) is equivalent to O(n^2).

Different inputs, different variables: When analyzing the performance of an algorithm with multiple inputs, use different variables to represent the size of each input. For example, if an algorithm takes two arrays as input, use n to represent the size of the first array and m to represent the size of the second array.

Worst case analysis: When analyzing the performance of an algorithm, consider the worst case scenario. For example, if an algorithm takes longer to run when the input is sorted in reverse order, use that scenario when calculating its Big O notation.

Rebecca and Stephanie are earning money by walking their neighbor's dogs. They get a flat rate of $25 plus $5 for every dog they walk. If they earned $75, then Rebecca and Stephanie walked 10 dogs in total.

The subject of the question is related to earnings and arithmetic calculations. Let's denote the number of dogs walked by "x". According to the given information, Rebecca and Stephanie earn $5 for every dog they walk, in addition to a flat rate of $25. Therefore, the equation representing their earnings can be written as:

Total earnings = Flat rate + (Earnings per dog * Number of dogs)

$75 = $25 + ($5 * x)

To solve the equation, we isolate the variable "x" by subtracting $25 from both sides:

$75 - $25 = $5x

$50 = $5x

Next, we divide both sides of the equation by $5 to solve for "x":

$50/$5 = x

10 = x

Therefore, Rebecca and Stephanie walked 10 dogs in total.

y=3/5x-2 is the  equation of the line shown in the table  in slope intercept form

The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.

The slope intercept form of a line is y=mx+b, where m is slope and b is the y intercept.

The slope of line passing through two points (x₁, y₁) and (x₂, y₂) is

m=y₂-y₁/x₂-x₁

Let us consider any two values

(5,1) and (10, 4)

m=4-1/10-5

=3/5

Now let us find the y intercept

We are given the original function $f(x)$ and the proposed new function p(x), which is obtained by horizontally stretching $f(x)$ by a factor of 5. The proposed equation for p(x) is:

p(x) = f(5x)

And we are also given a specific expression for $f(x)$:

Answer:

Step-by-step explanation:

There are four 4s and four 7s in a deck of 52 cards, so the probability of drawing a 4 or a 7 is:

P(4 or 7) = P(4) + P(7) = 4/52 + 4/52 = 8/52

Simplifying this fraction, we get:

P(4 or 7) = 2/13

Therefore, the probability of getting a 4 or a 7 from a deck of 52 cards is 2/13, or approximately 0.1538 or 15.38%.

The probability of getting a 4 or a 7 is 2/13.

Probability is simply the possibility of getting an event. Or in other words, we are predicting the chance of getting an event.

The value of probability will be always in the range from 0 to 1.

Given that,

You have a deck of 52 cards.

Number of cards which are 4 = 4

Number of cards which are 7 = 4

Number of cards which are either 4 or 7 = 4 + 4 = 8

Total number of cards = 52

For given question,

We need to find the critical values for a 2-tailed sign test for 13-coin flips.

We have been given an alpha level of 0.05 that is 5%

⇒ α = 0.05

We know that in hypothesis testing, a critical value is a point on the test distribution that is compared to the test statistic to determine whether to reject the null hypothesis.

These are the points on the distribution which have the same probability as your test statistic, equal to the significance level α.

The critical values are assumed to be at least as extreme at those critical values.

Now we find 1 - α

⇒ 1 - α = 1 - 0.05

⇒ 1 - α = 0.95

Because it is a two-tailed test, we are going to divide 0.95 by 2.

⇒ 0.95/2 = 0.475

Now we look in the z-table to find out cutoff points.

For the area of 0.475, the critical values is ± 1.96 .

Answer:

There are many times in algebra when you need to simplify an expression. The properties of real numbers provide tools to help you take a complicated expression and simplify it.

The associative, commutative, and distributive properties of algebra are the properties most often used to simplify algebraic expressions. You will want to have a good understanding of these properties to make the problems in algebra easier to work.

Step-by-step explanation:

Commutative Property of Multiplication

For any real numbers a and b, a · b = b · aOrder does not matter as long as the two quantities are being multiplied together. This property works for real numbers and for variables that represent real numbers.

just as subtraction is not commutative, neither is division commutative. 4 ÷ 2 does not have the same quotient as 2 ÷ 4.Associative Property of Addition

For any real numbers a, b, and c, (a + b) + c = a + (b + c).

Associative Property of Multiplication

For any real numbers a, b, and c, (a • b) • c = a • (b • c).Multiplication has an associative property that works exactly the same as the one for addition. The associative property of multiplication states that numbers in a multiplication expression can be regrouped using parentheses. For example, the expression below can be rewritten in two different ways using the associative property.

The parentheses do not affect the product, the product is the same regardless of where the parentheses are.

The distributive property of multiplication is a very useful property that lets you rewrite expressions in which you are multiplying a number by a sum or difference. The property states that the product of a sum or difference, such as 6(5 – 2), is equal to the sum or difference of products, in this case, 6(5) – 6(2).

   6(5 – 2) = 6(3) = 18

 65) – 6(2) = 30 – 12 = 18

The distributive property of multiplication can be used when you multiply a number by a sum. For example, suppose you want to multiply 3 by the sum of 10 + 2.3(10 + 2) = ?

According to this property, you can add the numbers 10 and 2 first and then multiply by 3, as shown here: 3(10 + 2) = 3(12) = 36. Alternatively, you can first multiply each addend by the 3 (this is called distributing the 3), and then you can add the products. This process is shown here.

3 (10 + 2) = 3(12) = 36

3(10) + 3(2) = 30 + 6 = 36

The products are the same.

since multiplication is commutative, you can use the distributive property regardless of the order of the factors.

The values: y - 2 = 4 * (x - 5) Now, set x = 0 and solve for y: y - 2 = 4 * (0 - 5) y - 2 = -20 y = -18 So, the point where the line crosses the vertical axis is (0, -18).

To find the point where the line through (5, 2) with slope 4 crosses the vertical axis, we first need to use the given formula to find the equation of the line.

Using the point-slope form of a line, we have:

y - y1 = m(x - x1)

where m is the slope and (x1, y1) is the given point (5, 2).

Plugging in m = 4 and (x1, y1) = (5, 2), we get:

y - 2 = 4(x - 5)

Simplifying, we get:

y = 4x - 18

To find the point where this line crosses the vertical axis, we set x = 0 and solve for y:

y = 4(0) - 18

y = -18

So the point where the line crosses the vertical axis is (0, -18).

Therefore, the answer is (x, y) = (0, -18).

To summarize, we used the given formula to calculate the equation of the line through (5, 2) with slope 4, and then found the point where this line crosses the vertical axis by setting x = 0 and solving for y.
