Answer:

i think it might be y=0.6x - 2

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

1=3/5(5)+b

1=3+b

b=-2

So the slope intercept form is y=3/5x-2

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

The critical values for a 2-tailed sign test for 13-coin flips (alpha of. 05) is: ± 1.96

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 .

Therefore, the critical values for a 2-tailed sign test for 13-coin flips (alpha of. 05) is: ± 1.96

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)

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.

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.

A The null and alternative hypotheses in this case are:

Null hypothesis: H_o: μ ≥ 11

Alternative hypothesis: H_A: μ < 11

B We have statistically significant evidence to conclude that the setting results in less than 11% kernels unpopped.

C The t-statistic is -2.94.

d) The p-value is 0.004.

a) In this case, the company has made a Type I error. This is when the null hypothesis is rejected, even though it is true. In this case, the company would be rejecting the hypothesis that the setting results in less than 11% kernels unpopped, even though it is actually true. The consequence of this would be that the company would be losing money on refunds for popcorn that is not actually defective.

b) In order to answer this question, we need to calculate the t-statistic and the p-value.

The t-statistic is calculated as follows:

t = (x - μ) / (s / √n)

Substituting these values into the formula for the t-statistic, we get:

t = (6.7 - 11) / (3.5 / √8)

= -2.94

The p-value is the probability of obtaining a t-statistic that is at least as extreme as the one we observed, assuming that the null hypothesis is true. In this case, the p-value is 0.004.

c) The t-statistic is -2.94.

d) The p-value is the probability of obtaining a t-statistic that is at least as extreme as the one we observed, assuming that the null hypothesis is true. In this case, the p-value is 0.004.The p-value is 0.004.

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.

Set each factor equal to zero and solve for x.

The roots or x intercepts are -2 and -5, which is where the parabola crosses the x axis. This represents the locations (-2,0) and (-5,0) respectively.

Side note: The quadratic formula can be used to solve x^2+7x+10 = 0 as an alternative route.

-------------

The roots found were -2 and -5.

The x coordinate of the vertex is found at the midpoint of these roots.

Add them up and divide in half

(-2 + -5)/2 = -7/2 = -3.5

Plug this value into the function to find the y coordinate of the vertex.

f(x) = x^2+7x+10

f(-3.5) = (-3.5)^2+7(-3.5)+10

f(-3.5) = -2.25

The vertex is located at (-3.5, -2.25)

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

Probability = 8/52 = 2/13

Hence the probability is 2/13.

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).

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.
