x > 2

As x > 2, the value of x is 4.

5) We need to find the solution to a given linear equation.

Consider a linear equation,

2/5 + p = 4/5 + 3/5p

Blocking Scheme:

In this subsection, the goal is to construct a blocking design such that the blocking effects are orthogonal to the terms in the linear main effects model so that a linear plus quadratic main effects model can be estimated. Assume that all m-factors are quantitative and an m0-factor DSD is constructed. where m0 = m + k and n = 2(m + k) + 1 runs.  Removing the intermediate run from  results in a 2(m + k) run design.

Randomization:

When you randomize an experiment, you select subjects at random. For example, you can use simple random sampling. In this case, participant names are randomly drawn from a pool with each having an equal probability of being selected. You can also randomly assign treatments to participants by assigning random numbers from a random number table.

If you use randomization in your experiments, protect yourself from bias. For example, selection bias (where some groups are underrepresented) is eliminated and accidental bias (where random imbalance occurs) is minimized. If your sample is random, you can also run various statistical tests on the data (to test hypotheses).

Events A and B dependent as occurrence of one event does not affect the chances of the occurrence of the other event.

Probability is a branch of mathematics in which the chances of experiments occurring are calculated. It is by means of a probability, for example, that we can know from the chance of getting heads or tails in the launch of a coin to the chance of error in research.

To understand this branch, it is extremely important to know its most basic definitions, such as the formula for calculating probabilities in equiprobable sample spaces, probability of the union of two events, probability of the complementary event, etc.

Two events are independent if the occurrence of one event does not affect the chances of the occurrence of the other event. The mathematical formulation of the independence of events A and B is the probability of the occurrence of both A and B being equal to the product of the probabilities of A and B (i.e., P(A and B).

Since we have given that;

A be the event that a store sells all of their ground hamburger for the week

P(A)=0.75

B be the event that that the store sells all of it's steak for the week is

P(B)=0.68

The probability that the store sells all of both of the meats for the week is 0.62.

P(A|B)=0.62

but for A and B to be independent ,

P(A).P(B)= P(A and B)

0.75×0.68=0.51

but,

[tex]P(A|B) = \frac{P(AnB)}{P(B)}[/tex]

P(AnB) = 0.62 x 0.68

Answer:

I believe the answer is 5

Step-by-step explanation:

the actual velocity of the plane is 380 mph [14.6° east of south], and the actual speed and direction of the plane are 380 mph and 14.6° east of south respectively.

Actual velocity vector = 380 mph [14.6° east of south]

Actual speed = 380 mph

Actual direction = 14.6° east of south

The actual velocity of the plane can be determined by subtracting the velocity of the tail wind (80 mph) from the initial velocity of the plane (460 mph). This gives us a result of 380 mph. To calculate the direction of the actual velocity, we need to subtract the direction of the tail wind (20 degrees west of south) from the direction of the initial velocity of the plane (10 degrees east of south). This gives us a result of 14.6° east of south. Therefore, the actual velocity of the plane is 380 mph [14.6° east of south], and the actual speed and direction of the plane are 380 mph and 14.6° east of south respectively.

2- There are 0 or more child nodes of the root node.

3- There are zero or more child nodes for each child node, and so forth. As a result, the tree gains a subtree. Each node has a separate subtree that consists of its offspring and their offspring, etc. This implies that any node can function as a tree on its own.

In addition, a binary search tree (BST) has the following two features:

we get the expected number of farms in the sample whose land value per acre is between $1800 and $2600 is 59.

The Empirical Rule (or 3 sigma rule) states that for a normal distribution (bell shaped distribution) 68% of the data falls within one standard deviation (μ ± σ), 95% percent within two standard deviations (μ ± 2σ), and 99.7% within three standard deviations from the mean (μ ± 3σ).

Given that the mean (μ) = $2200, standard deviation (σ) = $400

a) The percentage of data within one standard deviation = μ ± σ = (2200 ± 400) = (1800, 2600)

Hence 68% of the land are between ​$1800 and ​$2600.

Number of farms = 68% × number of sample = 0.68 × 80 = 54.4 ≈ 54 farms

Step-by-step explanation:

We have to first multiply 25 times 12 (because 6 hours is 12 half hours) which is 300.
300 plus his starting point, 120 is 420.

Therefore, your answer is 420 feet.

Answer: 420 feet

Step-by-step explanation:

Because Daniel climbed 25 feet every half hour for 6 hours, 25 feet is added 12 times to the 120 feet he already climbed.

120 + (25 × 12)

25 × 12 = 300

The ordered pair which is a solution to the system of linear equations (0,2).

In mathematics, a system of linear equations refers to a collection of one or more linear equations which involve the same variables. In order to solve the system of linear equations, multiply each equation by a constant such as the coefficient of one variable becomes the same.

Hence, multiply 2x + 3y= 6 by 3 and –3x + 5y = 10 by 2.

3 (2x + 3y= 6)

6x + 9y = 18

2(–3x + 5y = 10)

-6x + 10 y = 20

Adding the two equations

6x + 9y = 18

-6x + 10 y = 20

19y = 38

y = 2

Substitute y in either of the equations:

2x + 3(2)= 6

2x = 6 – 6 = 0

x = 0

Hence, the solution is (0, 2)

The ordered pair (0,0) is not a solution as it will invalid the given linear equation.
