Yes, his pulse rate is in the normal range for children. His pulse rate was calculated to be 120 beats per minute, which falls within the range of 60-100 beats per minute.
The student took his resting pulse rate by counting the number of beats in 20 seconds. He then multiplied his result by three to calculate his pulse rate for a minute. To determine if his pulse rate was within the normal range for children, he compared his result to the data shown in the table. His pulse rate of 120 beats per minute was within the range of 60-100 beats per minute, so it was considered to be normal for children. To ensure accuracy, the student could have taken his pulse rate for a longer period of time, such as 30 or 60 seconds, before calculating his pulse rate for a minute. This would have given him a more accurate result.

Two restaurants sell meals for different prices, as shown below. Sophia wants to buy 2 meals. What is the difference between the prices she would pay at the two restaurants? Give your answer in pounds (£). < Back to task Restaurant A £16.50 each Buy one meal, get another one half price Scroll down Watch video Restaurant B £16 each Buy two meals, get 15% off the cost of both Answer >
Sophia would pay £2.45 less if she bought her 2 meals at Restaurant B
What is cost?
Cost is the value of money that has been used up to produce something or deliver a service, and hence is not available for use anymore.
First, let's find the total cost of 2 meals at Restaurant A. The first meal costs £16.50, and the second meal is half-price, so it costs £16.50 / 2 = £8.25.
The total cost of 2 meals at Restaurant A is £16.50 + £8.25 = £24.75.
Next, let's find the total cost of 2 meals at Restaurant B. The meals each cost £16, so the total cost of 2 meals is £16 * 2 = £32.
After applying a 15% discount, the total cost of 2 meals is £32 * (1 - 0.15) = £27.20.
Finally, let's find the difference between the prices Sophia would pay at the two restaurants:
£24.75 - £27.20 = -£2.45
So, Sophia would pay £2.45 less if she bought her 2 meals at Restaurant B

The difficulty of range as a measure of variability that is overcome by interquartile range is option b that is The range is influenced too much by extreme values.
What is variance?The variance is the mean squared difference between each data point and the mean-centered distribution. A statistical assessment of the dispersion of values in a data collection is referred to as variance. Variance explicitly assesses how distant each number in the set is from the mean (average), and consequently from every other number in the set. Variance is a measure of how data points differ from the mean, whereas standard deviation is a measure of statistical data distribution. The primary distinction between the two is that standard deviation is expressed in the same units as the mean of the data, whereas variance is expressed in squared units.
Here,
The interquartile range overcomes the problem of range as a measure of variability. Extreme values have an undue impact on the range.

Disregarding intermediate, let's assume she has access to a letter that can be powerful or weak. Let's say she receives a persuasive letter. If she receives a strong letter, her chance of being hired is then increased.

Let's assume that we have some knowledge of such two numbers. I believe
In addition, we recognize how likely it is that she will receive either one or both letters: P(J|S)=0.8 P(J|W)=0.1

Step-by-step explanation:
Choose the method of pay that would result in the most earnings for one month on sales of $60,000.
The method of pay that would result in the most earnings for one month on sales of $60,000 would be: d. Graduated commission of 5% on the first $40,000 in sales and 9% on anything over that.
How to find the earnings?The earnings can be calculated as follows:
a. Earnings = 6% of 60000
Earnings = $3,600
b. Earnings = 1500 + .03(60000)
Earnings = 1500 + 1800
Earnings = $3,300
c. For the first $50,000: $50,000 * 4% = $2,000
For the remaining $10,000: $10,000 * 10% = $1,000
Total earnings: $2,000 + $1,000 = $3,000
d. For the first 5 % ×40,000 = 2000
For the remaining (60,000-40,000) = .09 x 20000 = 1800
Total earnings :2000 + 1800 = $3,800

The measurement of the side g in the Δ EFG is 218.38
What is sine rule of triangle?The law of sine or the sine law states that the ratio of the side length of a triangle to the sine of the opposite angle, which is the same for all three sides.
Given that, In Δ EFG, f = 400 inches, m ∠ F = 94° and m ∠ G = 33°, we need to find, the length of g (refer to figure attached)
Using the sine rule of the triangle,
f / Sin F = g / Sin G = e / Sin E

Answer:
80%
Step-by-step explanation:
Gross Pay = $3851
Deductions = $756.72
Take-home Pay = $3851 - $756.72 = $3,094.28
Ratio of take-home pay to gross pay = 3,094.28/3851 = 0.8035
As a percentage = 0.8035 x 100 = 80.35%

consider a data set with at least three data values. suppose the highest value is increased by 10 and the lowest is decreased by 10. (a) does the mean change? explain.
If the highest value is increased by 10 and the lowest is decreased by 10 the mean doesn't change
Let us assume the data set with 10 observations:
{5, 6, 4, 3, 2, 6, 4, 9, 4, 4}.
Arranging data set in ascending order
{2, 3, 4, 4, 4, 4, 5, 6, 6, 9}
Mean of this data = Sum of all observations/Total number of observations
Mean = (2 + 3 + 4 + 4 + 4 + 4 + 5 + 6 + 6 + 9)/10
Mean = 47/10 = 4.7
Now, Increasing the highest value by 10 and decreasing the lowest value by 10
So, the new data set is {-8, 3, 4, 4, 4, 4, 5, 6, 6, 19}
Mean of this data = -8 + 3 + 4 + 4 + 4 + 4 + 5 + 6 + 6 + 19/10
Mean = 47/10 = 4.7

the standard deviation is used in conjunction with the
When describing bell-shaped distributions statistically, the standard deviation is utilised along with the mean.
What does the mean actually measure?
While the standard deviation gauges the distribution's spread, the mean gauges the distribution's centre.
What is the purpose of standard deviation?
For the aim of quantifying dispersion, or the variation that takes place in the values of a data set that is taken into consideration, the standard deviation is used. The data points are said to be close to the mean when the standard deviation number is reduced. The opposite will occur when it is higher. In this way, it gauges how widely apart data points are from the mean.
Anything's predicted value is sometimes referred to as a mean. It is the object that serves as the focal point for all data points. The standard deviation determines how widely apart all the data points are from the mean, whereas the mean is the centre of the distribution.
What is the name of standard deviation?
Because it is the square root of the means of the squared errors from the arithmetic average, standard deviation is often referred to as root-mean square deviation. Standard deviation is a word used in economics to indicate how risky an investment is.

Generally, which one of the following is the least appropriate measure of central tendency for a data set that contains outliers? a. mean b. median c. 2nd quartile d. 50th percentile
The least appropriate measure of central tendency for a data set that contains outliers is the mean. This is because the mean is calculated by taking the sum of all the values in the data set and dividing it by the number of values. This means that the mean is heavily influenced by outliers, as they are included in the calculation.
The median, 2nd quartile, and 50th percentile are all more appropriate measures of central tendency for a data set that contains outliers, as they are not affected by the presence of outliers. The median is calculated by taking the middle value of the data set, the 2nd quartile is calculated by taking the median of the upper half of the data set, and the 50th percentile is calculated by taking the value at the 50th percentile of the data set.

if the plant filled each of its cans to 12 ounces, what would be the standard deviation of the sample of 10 cans?
If each of the plant's cans was filled to 12 ounces, the standard deviation of the sample of 10 cans would give us an idea of how much the weights of the cans deviate from the average weight of 12 ounces.
The calculation of the standard deviation requires knowledge of the mean and variance of the sample. To find the variance, we would need to subtract the mean from each of the observed weights, square the differences, and find the average of the squared differences. Finally, to find the standard deviation, we would take the square root of the variance.
It's worth noting that in practice, finding the standard deviation of a sample can be a complex and time-consuming process, especially when dealing with large sample sizes. However, it is a valuable metric that provides important information about the distribution and spread of the data.
