Answer:

The given ratios are proportional

Step-by-step explanation:

To consider the fractions as "proportional", they must be equivalent. Let us assume that the fractions are equivalent. Then, we get;

\(\implies \dfrac{10}{24} = \dfrac{5}{12}\)

When using cross multiplication, we get;

\(\implies \dfrac{10}{24} = \dfrac{5}{12}\)

\(\implies 10 \times 12 = 24 \times 5\)

When simplified, we get;

\(\implies 10 \times 12 = 24 \times 5\)

\(\implies 120 = 120 \ \checkmark\)

Therefore, the relationship is proportional.

Answer: -39 is the answer

Step-by-step explanation:

If a person has a slow reaction time that puts them in the top 10% of responses, it means that their reaction time is slower than 90% of the population.

The value that separates the top 10% of responses from the bottom 90% is determined by the distribution of reaction times in the population.

Assuming a normal distribution of reaction times, the value that separates the top 10% of responses from the bottom 90% is the 90th percentile. This means that 90% of the population has a reaction time below this value, while the top 10% have a reaction time equal to or above it.

The specific value that separates the top 10% from the bottom 90% can vary depending on the population being studied and the task being performed. However, in general, a value around 1.5 standard deviations above the mean reaction time would be a reasonable estimate for the 90th percentile.

Finding m‹2 :

\({ \tt{m \angle2 = (7x + 1) \degree}} \\ { \tt{m \angle2 = (7 \times 7) + 1}} \\ { \bf{m \angle2 = 50 \degree}}\)

Answer:

m∠2 = 50

Step-by-step explanation:

7x + 1 and 18x + 4 are angles in a linear pair.

Sum of linear pair angles is supplementary.

7x + 1 + 18x + 4 = 180

7x + 18x + 1 + 4 = 180

25x + 5 = 180

25x = 180 - 5

25x = 175

x = 175 / 25

x = 7

Substitute x = 7 in 7x + 1,

7x + 1

= 7 ( 7 ) + 1

= 49 + 1

= 50

7x + 1 and ∠2 are vertically opposite angles and vertically opposite angles are equal.

∠2 = 7x + 1

∠2 = 50

Using (D) the binomial formula, which is used to determine probability when independent events are known, we will get the probability in the scenario.

In an experiment with two possible outcomes, the likelihood of exactly x successes on n repeated trials is known as the binomial probability (commonly called a binomial experiment).

The binomial probability is nCx⋅px⋅(1−p)n−x if the likelihood of success on a single trial is p.

When a process is repeated a certain number of times (for example, in a set of patients), the result for each patient can either be a success or a failure, the binomial distribution model enables us to calculate the probability of witnessing a defined number of "successes."

So, in the given situation we will find the probability with help of the binomial formula which is used to calculate the probability when independent events are given.

Therefore, using (D) the binomial formula, which is used to determine probability when independent events are known, we will get the probability in the scenario.

(D) the binomial formula.

The probability of finding 10 defective cores in a sample of 10 power cores is approximately 0.0000161, or about 0.0016%.

Assuming that each fuel rod is independent of each other and that the probability of finding a defective fuel rod is constant at 0.1%, we can model the number of defective fuel rods in a power core with a binomial distribution. Let X be the number of defective fuel rods in one power core, then X follows a binomial distribution with parameters n = 50000 and p = 0.1/100 = 0.001.

To find the probability of finding 10 defective cores, we can use the binomial distribution again, but with a different set of parameters. Let Y be the number of defective cores in a sample of 10 power cores, then Y follows a binomial distribution with parameters n = 10 and p = P(X ≥ 1), where P(X ≥ 1) is the probability of finding at least one defective fuel rod in one power core. We can find P(X ≥ 1) using the complement rule:

P(X ≥ 1) = 1 - P(X = 0)

= 1 - (1 - 0.001)^50000

≈ 0.3935

So, the probability of finding 10 defective cores in a sample of 10 power cores is:

P(Y = 10) = (10 choose 10) * (0.3935)^10 * (1 - 0.3935)^(10 - 10)

≈ 0.0000161

In March the baker will sell 34 chocolate chip cookies. In April he will sell 74 cookies.

Step-by-step explanation:

So first, we end up doubling the original amount of cookies from January for February which gets us 20 cookies, he takes 6 homes leaving us with 14. He continues to double the FULL amount so he doubles 20 for March which gets us 40, then we again take 6 away leaving us with 34. We do the same thing for April. Double 40 getting 80, take away 6 you get 74. Done.

Greetings from Brasil...

Its attached the diagram of the situation.....

The ground is 8 feet from the bottom edge of the window

We start by representing the building, the ladder and the ground in a sketch.

See attachment for diagram

From the diagram, the distance (d) from ground to the bottom edge of the window is calculated using Pythagoras theorem:

10^2 = d^2 + 6^2

Evaluate the squares

100 = d^2 + 36

Evaluate the like terms

d^2 = 64

Take the square root of both sides

d = 8

Hence, the ground is 8 feet from the bottom edge of the window

On the images, I messed up on some things, but the answers above are good.

The probability that the mean of a sample of 70 computers would differ from the population mean by less than 1.9 months is 0.1217.

In this problem, we have to find the probability that the mean of a sample of 70 computers would differ from the population mean by less than 1.9 months, given that the quality control manager believes that the mean life of a computer is 105 months, with a variance of 81.

To solve this problem, we can use the Central Limit Theorem, which states that the sample mean of a sufficiently large sample size, drawn from any population, will be approximately normally distributed with mean μ and variance σ²/n, where μ is the population mean, σ² is the population variance, and n is the sample size.

In this case, we know that the population mean is μ = 105 months and the population variance is σ² = 81. Since we are interested in the mean of a sample of 70 computers, we can use the formula for the standard error of the mean, which is σ/√n, to calculate the standard deviation of the sampling distribution of the mean.

The standard deviation of the sampling distribution of the mean is given by σ/√n = √(81/70) ≈ 1.226.

Now, we want to find the probability that the mean of a sample of 70 computers would differ from the population mean by less than 1.9 months. We can standardize this difference using the formula

z = (x' - μ)/(σ/√n), where x' is the sample mean.

Substituting the values, we get z = (x' - 105)/(1.226), and we want to find the probability that |z| < 1.9/1.226 ≈ 1.550.

Using a standard normal distribution table, we can find that the probability of |z| < 1.550 is approximately 0.1217.

Therefore, the probability that the mean of a sample of 70 computers would differ from the population mean by less than 1.9 months is 0.1217.

The required value of m is given as 25/4 as of the given proportionality.

Given that,

P is inversely proportional to the square root of m. P = 10 when m = 1/4 to work out the value of m when P = 2​.

proportionality is defined as between two or more sets of values, and how these values are related to each other in the sense are they directly proportional or inversely proportional to each other.

here,

According to the question,

P ∝ 1 / √m

Now,

P₁/P₂ = √m₂/√m₁

Substitute the value in the above equation,

10/2 = √m₂/√1/4

√m₂ = 5/2

m₂ = 25/4 researchers

Step-by-step explanation:

Answer: 22

Step-by-step explanation:

Ok, so the way I do it I multiply then divide.

For Monday I did: ?/220=55/100. what you would do is multiply across then divide by the other number, so 220x55 which is 12100 then you will divide it by 100. So 121 people voted on Monday

For Tuesday: Using the same method. ?/220=45/100 you will multiply 45x220 giving you 9900 then you will divide by 100 giving you 99. 99 people voted on Tuesday.

So to find the DIFFERENCE you need to subtract, so 121-99 leaving you with 22. Also, if you are confused how on where I got 100 from you put the percentage over 100, because percentages go from 0%-100% so you put the partial percentage over the maximum (100)
