The limit dimensions of the part are **1.475 in.** to **1.495 in.**

The blueprint specification states that the thickness of the machined part should be 1.485 in. with a tolerance of 0.010 in. Tolerance refers to the acceptable deviation from the specified dimension. In this case, the tolerance is ±0.010 in., which means the actual thickness can vary by up to 0.010 in. in either direction.

To find the limit dimensions, we need to consider both the upper and lower limits. The lower limit is calculated by subtracting the tolerance from the specified dimension, while the upper limit is obtained by adding the tolerance to the specified dimension.

Lower limit: 1.485 in. - 0.010 in. = 1.475 in.

Upper limit: 1.485 in. + 0.010 in. = 1.495 in.

Therefore, the limit dimensions of the part are 1.475 in. to 1.495 in. These limits ensure that the part is within the acceptable range of thickness specified by the blueprint.

Answer:

24

Step-by-step explanation:

Cost of membership + game = 2.50x + 54

Cost of just games = 4.75x

The catch is, how do we make up the 54 dollars?

So equate the 2 costs

4.75x = 2.50x + 54      Subtract 2.50

4.75x - 2.50x = 54       Combine

2.25x = 54                    Divide by 2.25

x = 54/2.25

x = 24

That means that 24 is the break even point.

Answer:

The total number of elements in the sample space of the experiment for 3 stages = 64 (C)

Step-by-step explanation:

The number of equally likely sample outcomes of the single stage experiment = 4

For n number of stages, the total number of elements in the sample space = (outcome of a single stage)^n

This is = 4^n

To determine the total number of elements in the sample space if the experiment has 3 stages, we would multiply the outcome of one experiment three times.

Where n = 3

The total number of elements in the sample space of the experiment for 3 stages = 4³

= 4×4×4 = 64

The total number of elements in the sample space of the experiment for 3 stages = 64 (C)

Answer:

8 family members.  Average of 2.6 fish per person.

Step-by-step explanation:

How many family members caught fish?  Count only those members who caught at least 1 fish (that's all of them, because nobody caught 0 fish!).

3 + 1 + 0 + 4 = 8 family members.

Average number of fish caught per person.  This is the total number of fish caught divided by the total number of people.

This is a little bit tricky because, for example, 4 people caught 4 fish, making 4 x 4 = 16 fish caught.

Multiply number of fish (column 1) by the number of people (column 2):

1 x 3  +  2 x 1  +  3 x 0  + 4 x 4 = 3 + 2 + 0 + 16 = 21 fish caught.

21 fish.  8 people.  On average, that is 21 / 8 = 2.625 which rounds to 2.6 fish per person.

Hint:  the word "per" means divide, so "fish per person" tells you to divide the total number of fish by the total number of people.

Good Luck!

The sample that could constitute a discrete random variable is the number of near collisions of aircraft in a year.

This is because it is a countable, finite number and not a continuous measurement like the height of the ocean's tide. The total number of points scored in a football game could also be considered a discrete random variable because it is a countable, finite number. However, the height of the ocean's tide is a continuous measurement and cannot be counted as a discrete random variable.
The sample that could constitute a discrete random variable is: i. total number of points scored in a football game.
A discrete random variable represents a countable number of distinct values or outcomes. In this case, the total number of points scored in a football game can be counted and listed, making it a discrete random variable.
On the other hand, the height of the ocean's tide at a given location (ii) is a continuous random variable, as it can take any value within a given range, and the number of near collisions of aircraft in a year (iii) could also be considered as a discrete random variable, but it's not one of the options in your question.

True. The coefficient of determination (R²) measures the proportion of the variation in the dependent variable that is explained by the regression model.

In statistics, the coefficient of determination (denoted R² or r² and pronounced "R squared") is used in the context of statistical models whose main purpose is either the prediction of future results or the testing of hypotheses, on the basis of other related information.

It is also known as the multiple correlation coefficient or the multiple determination coefficient. It is the proportion of the variance in the dependent variable that is predictable from the independent variable(s).

In a simple regression model, this is the square of the correlation between the dependent variable and the single independent variable.

Hence, the given statement is True.

According to the Chebyshev inequality, the probability of Z being greater than or equal to 0.95 is less than or equal to pi. The actual probability is approximately 0.1587.

According to Chebyshev's inequality, for any random variable X with expected value E(X) and standard deviation sigma, the probability of X deviating from its expected value by more than k standard deviations is at most 1/k^2. Mathematically,

P(|X - E(X)| >= k * sigma) <= 1/k^2

In this case, we have a standard normal variable Z with E(Z) = 0 and sigma = 1. We want to find the probability of Z being greater than or equal to 0.95, which is equivalent to finding P(Z >= 0.95).

We can use Chebyshev's inequality with k = 2 to bound this probability as follows:

P(Z >= 0.95) = P(Z - 0 >= 0.95 - 0) = P(|Z - E(Z)| >= 0.95) <= 1/2^2 = 1/4

So, we have P(Z >= 0.95) <= 1/4. However, this is a very conservative bound and we can get a better estimate of the probability by using the standard normal distribution table or a calculator.

Using a calculator or a software, we get P(Z >= 0.95) = 0.1587 (rounded to four decimal places), which is much smaller than the upper bound of 1/4 given by Chebyshev's inequality.

Therefore, we can conclude that P(Z >= 0.95) <= pi (approximately 3.1416) according to Chebyshev's inequality, but the actual probability is approximately 0.1587.

Step-by-step explanation:

Given

The percentage of household with 2 people

First, calculate the total frequency

\(Total = 3 + 4 +6+7+5\)

\(Total = 25\)

The frequency of household with 2 people is:

\(f(2) = 4\)

So, the percentage is calculated as:

\(\% =\frac{f(2)}{Total} * 100\%\)

\(\% =\frac{4}{25} * 100\%\)

\(\% =\frac{400}{25}\%\)

\(\% =16\%\)

Answer:

y=2x+1.

Step-by-step explanation:

You first need to find the slope of the line already graphed. -2 to 1 would be three units to the right, and -2 to 4 would be six units up. You would use the equation (y2-y1)/(x2-x1), where x1 and y1 would be the x and y values of the first coordinate of the graphed line, and x2 and y2 would be the second coordinate. This would be 6/3, which can be simplified to 2/1, which can be simplified to 2, which would mean the slope of the given line would be 2, as well as the parallel line. Now, you could use a pretty complicated equation to find the y-intercept of the line you need to graph, but I would recommend using the slope to find it. Since the given point is (3, 7), you would need to go to the left, meaning you would reverse the slope until you reach the y-axis, so you would use -2 as the slope. 3*-2=-6, and 7-6=1, so the y-intercept would be 1. The answer would be y=2x+1. Hope this helps.

Answer:

Here we have 6 cars.

And we know that there are 4 people in each car.

The question is incomplete, I assume that we want to find the total number of people in the 6 cars.

So, again, there are 6 cars, and 4 people in each one.

Then we have 6 times 4 people.

This is equal to the product between 6 and 4, which is:

6*4 = 24

There is a total of 24 people in the 6 cars.

A = 2π ∫ [3, 5] √((5 - x)(1 + (1/4) * (5 - x)^(-1))) dx. This integral can be evaluated using standard techniques, such as substitution or expanding the exon.

To find the exact area of the surface obtained by rotating the curve y = √(5 - x) about the x-axis over the interval 3 ≤ x ≤ 5, we can use the formula for the surface area of revolution. The second paragraph will provide a step-by-step explanation of the calculation.

The formula for the surface area of revolution about the x-axis is given by: A = 2π ∫ [a, b] y * √(1 + (dy/dx)²) dx,

where a and b are the limits of integration.

In this case, the limits of integration are 3 and 5, as given in the problem statement.

First, we need to calculate dy/dx, the derivative of y with respect to x. Taking the derivative of y = √(5 - x), we have:

dy/dx = (-1/2) * (5 - x)^(-1/2) * (-1) = (1/2) * (5 - x)^(-1/2).

Now we substitute the values into the formula for surface area:

A = 2π ∫ [3, 5] √(5 - x) * √(1 + ((1/2) * (5 - x)^(-1/2))²) dx.

Simplifying the expression inside the integral, we have:

A = 2π ∫ [3, 5] √(5 - x) * √(1 + (1/4) * (5 - x)^(-1)) dx.

Next, we can combine the square roots:

A = 2π ∫ [3, 5] √((5 - x)(1 + (1/4) * (5 - x)^(-1))) dx.

This integral can be evaluated using standard techniques, such as substitution or expanding the exon. Apressifter performing the integration, we will have the exact value of the surface area of the rotated curve about the x-axis over the given interval.

The formula in statistic to calculate cards drawn at random without replacement shows both the cards are green is given by,

P(both cards are green)

= (number of green cards / total number of cards) × ((number of green cards - 1) / (total number of cards - 1))

The formula in statistics for calculating the probability of drawing two cards at random without replacement,

Both cards are green, depends on the total number of cards and the number of green cards in the deck.

Let us consider there are N total cards in the deck.

And k of them are green.

Probability of drawing two green cards without replacement,

use the following formula,

P(both cards are green)

= (number of green cards / total number of cards) × ((number of green cards - 1) / (total number of cards - 1))

⇒ P(two green cards) = (k/N) x ((k-1)/(N-1))

First term in the formula represents the probability of drawing a green card on the first draw.

Second term represents the probability of drawing a green card on the second draw.

First card was green and hasn't been replaced.

Assumes that each card in the deck is equally likely to be drawn.

And that the two draws are independent of each other .

For example,

A deck of 52 cards,

And there are 13 green cards in the deck (4 of each suit).

The probability of drawing two green cards without replacement would be,

P(two green cards)

= (13/52) x ((12/51))

= 0.0588

Therefore, the probability of drawing two green cards without replacement is approximately 0.0588 or 5.88%.

The value for df within in an experiment with two levels of factor a and three levels of factor b and five samples for each treatment condition is between 3.

Let n1 represent factor A's level of freedom.

Let n2 represent factor B's degree of freedom.

If factor A has five levels, then n1 = 2.

If Factor B has seven levels, then n2 = 3.

The formula is used to express how the degrees of freedom interact;

df = (n1 - 1)+(n2 - 1) (n2 - 1)

df = n1 -1 + n2- 1

df = n1 + n2 -2

Replace n1 and n2 to obtain df;

df = 2 + 3 - 2

df = 3
