Answer:

To calculate 2 3/4 of 500 grams, follow these steps:

1. Convert the mixed number to an improper fraction:

2 3/4 = (2 x 4 + 3)/4 = 11/4

2. Multiply the improper fraction by 500:

11/4 x 500 = (11 x 500)/4 = 2,750/4

3. Simplify the fraction by dividing the numerator and denominator by their greatest common factor, which is 2:

2,750/4 = (2 x 1,375)/(2 x 2) = 1,375/2

Therefore, 2 3/4 of 500 grams is equal to 1,375/2 grams or 687.5 grams.

Answer:44÷58+44

Step-by-step explanation:

Saif's performance was better.

An expression contains one or more terms with addition, subtraction, multiplication, and division.

We always combine the like terms in an expression when we simplify.

We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.

Example:

1 + 3x + 4y = 7 is an expression.

3 + 4 is an expression.

2 x 4 + 6 x 7 – 9 is an expression.

33 + 77 – 88 is an expression.

We have,

We will compare the run rates of Saif and Anus.

The run rate is the average number of runs scored per over.

Now,

The run rate of Saif.

Answer:

  6750 - 3894 = 2856

Step-by-step explanation:

You have to make use of the arithmetic facts you know.

The least-significant asterisk must be 0, because the sum of 4 and 6 is 10.

The 10s asterisk must be 9,so that the sum 5 + 9 + 1 has a least-significant digit of 5.

The 100s asterisk must be 7, because that is the least-significant digit of the sum 8 + 8 + 1 = 17.

The 1000s asterisk must be 3, so that 2 + 3 + 1 = 6.

(The "1" in each of these sums is the carry from the sum of the digits with the next lower place value.)

So, the subtraction problem is ...

  6750 - 3894 = 2856

_____

Comment on the solution method

For the most part, we worked this as an addition problem. The sum of the last two numbers must be equal to the first: 6570 = 3894 +2856. For some of us, addition facts are easier to work with than subtraction facts. The carry/borrow can be less confusing that way.

Answer:

0.4364 = 43.64% probability that the disposal of such capacitors will be regulated.

Step-by-step explanation:

To solve this question, we need to understand the normal probability distribution and the central limit theorem.

Normal Probability Distribution:

Problems of normal distributions can be solved using the z-score formula.

In a set with mean \(\mu\) and standard deviation \(\sigma\), the z-score of a measure X is given by:

\(Z = \frac{X - \mu}{\sigma}\)

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X.

Central Limit Theorem

The Central Limit Theorem establishes that, for a normally distributed random variable X, with mean \(\mu\) and standard deviation \(\sigma\), the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean \(\mu\) and standard deviation \(s = \frac{\sigma}{\sqrt{n}}\).

For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.

Mean of 48.3 ppm and a standard deviation of 8 ppm.

This means that \(\mu = 48.3, \sigma = 8\)

Sample of 40:

This means that \(n = 40, s = \frac{8}{\sqrt{40}}\)

Find the probability that the disposal of such capacitors will be regulated.

Sample mean above 48.5, which is 1 subtracted by the p-value of Z when X = 48.5. So

\(Z = \frac{X - \mu}{\sigma}\)

By the Central Limit Theorem

\(Z = \frac{X - \mu}{s}\)

\(Z = \frac{48.5 - 48.3}{\frac{8}{\sqrt{40}}}\)

\(Z = 0.16\)

\(Z = 0.16\) has a p-value of 0.5636.

1 - 0.5636 = 0.4364

0.4364 = 43.64% probability that the disposal of such capacitors will be regulated.

The distance between two points in three-dimensional space is a measure of the separation between the two points. In this case, the two points are the center of a sphere and a point that the sphere passes through.

To find the distance, we can use the distance formula in three dimensions, which is an extension of the distance formula in two dimensions. The distance formula is:

d = √((x1 - x2)^2 + (y1 - y2)^2 + (z1 - z2)^2)

where (x1, y1, z1) is the center of the sphere and (x2, y2, z2) is the point that the sphere passes through. The square root of the sum of the squares of the differences between the corresponding coordinates gives the distance between the two points.

In this problem, the center of the sphere is not given, so it is not possible to calculate the distance between the sphere and the point. The center of the sphere is a crucial piece of information needed to solve this problem.

By graphing or visualizing the parabolic shape, we can observe where the graph intersects the x-axis, which represents the solutions to the equation. In this case, the solutions are x = -3 and x = 1.

To solve the quadratic equation x^2 + 2x - 3 = 0 by graphing, we can plot the graph of the equation and find the x-values where the graph intersects the x-axis.

First, let's rearrange the equation to the standard form: x^2 + 2x - 3 = 0.

We can create a graph by plotting points for different values of x and then connecting them. However, I can describe the process and the key points on the graph.

1. Find the x-intercepts: These are the points where the graph intersects the x-axis. To find them, set y (the equation) equal to zero and solve for x:

  0 = x^2 + 2x - 3.

  This quadratic equation can be factored as (x + 3)(x - 1) = 0.

  Therefore, x = -3 or x = 1.

2. Plot the points: Plot the points (-3, 0) and (1, 0) on the graph. These are the x-intercepts.

3. Draw the graph: The graph of the equation x^2 + 2x - 3 = 0 is a parabola that opens upward. It will pass through the x-intercepts (-3, 0) and (1, 0).

The correct statement regarding the mean of the data-set when the score of 47 is removed is given as follows:

The mean increased by about 6.

The mean of a data-set is given by the sum of all observations in the data-set divided by the number of observations, which is also called the cardinality of the data-set.

The observations for this problem are given as follows:

100, 95, 47, 83, 87, 89, 89.

There are 7 observations, and their sum is given as follows:

100 + 95 + 47 + 83 + 87 + 89 + 89 = 590.

Hence the mean is of:

590/7 = 84.29.

Removing the observation of 47, there will be 6 observations, with a sum of 590 - 47 = 543, hence the mean is of:

543/6 = 90.5.

Answer:

Step-by-step explanation:

In March Ms. Turner drove 90 miles. If she drove 3 times as many miles in March as she did in January, then all we need to do at this point is multiply 3 to 90.

90 × 3 = 270

So Ms. Turner drove 270 miles in January.

Ms. Turner then drove 4 times as many miles in February as she did in January, so we will do the same here.

270 × 4 = 1080

Therefore, Ms. Turner drove 1,080 miles in February.

The mean speed of vehicles on a stretch of I-84 is 69.5 mph, with a standard deviation of 4 mph. A random sample of 64 vehicles is selected. Find the probabilty that the mean speed is 70 mph

Answer:

0.84134

Step-by-step explanation:

When given a random number of samples when asked to find probability of that a mean is equal to, less than or greater than a given number, the z score formula we use is :

z = (x- μ)/Standard error, where

x is the raw score,

μ is the population mean

n = Random number of samples

Standard error = is the population standard deviation/square root of randy number of samples

= σ /√n

Standard error = σ /√n

σ = 4 mph, n = 64

= 4/√64

= 4/8 = 1/2

= 0.5

z = (x- μ)/Standard error

x = 69.5mph μ = 70mph ,Standard error = 0.5

z = 70 - 69.5/0.5

z = 1

Using the z score table for find the probability,

P(x = 70) = P(z = 1)

= 0.84134

Therefore, the probability that the mean is 70mph = 0.84134
