The unit rate for Scented candles is 1/2(or 4/8) inches per hour.

The unit rate for unscented candles is 1/3(or 3/9) inches per hour

The scented candles burn more/faster per hour.

Step-by-step explanation:

Answer:

Below

Step-by-step explanation:

scented rate = 1/8 inch / 1/4 hr = 1/8 * 4/1 = 4/8 = 1/2 inch per hour

unscented rate 1/9 in / 1/3 hr  = 1/3 inch per hour    

scented burns more per hour because   1/2 > 1/3 in

I have to flip the coin 16 times to say that I am 95% confident the coin is unfair.

This question can be answered using the binomial distribution. If we assume the coin is fair, then each flip of the coin has a 50% chance of coming up heads. We can use the binomial distribution to calculate the probability of getting heads at least 95% of the time.

For this calculation, we need to know the number of trials, n. We can use the formula: n = (1.96^2)/(p(1-p)) to calculate n for a 95% confidence level. In this case, p = 0.5, so n = 15.84. Since this is not a whole number, we can round up to 16 flips.

Answer:

The transformation f(x)↦f(-x) , the graph of f(x) reflects it across the y-axis

Step-by-step explanation:

The main impact of increasing the standard deviation from 3.1 to 5.8 leads to a wider confidence interval, from (9.38, 10.62) to (8.88, 11.12).

This is because the standard deviation is a measure of the spread of the data, and the wider the spread, the wider the confidence interval will be. Mathematically, this can be shown by the following calculation:

The confidence interval is usually given by the formula:

where x is the mean of the sample, z is the z-score representing the confidence level, sigma is the standard deviation, and n is the sample size.

In this case, let's assume that x = 10, z = 1.96 (95% confidence interval), and n = 10. Then, when the standard deviation is 3.1, the confidence interval is 10 +/- (1.96*3.1/sqrt(10)) = 10 +/- 0.62, or (9.38, 10.62).

However, when the standard deviation is increased to 5.8, the confidence interval becomes 10 +/- (1.96*5.8/sqrt(10)) = 10 +/- 1.12, or (8.88, 11.12).

Therefore, increasing the standard deviation from 3.1 to 5.8 leads to a wider confidence interval, from (9.38, 10.62) to (8.88, 11.12).

here, we have,

Mathematically, we have the area of the sector as;

e/360 * pi * r^2

r is 8 cm

so we have

58 = e/360 * pi * 8^2

58/64 * 360/pi = e

e = 103.85

To get the perimeter,

we have length of the arc plus 2r

Length of the arc is;

e/360 * 2 * pi * r

add 2 r;

e/360 * 2 * pi * r + 2r

so we have

103.85/360 * 2 * pi * 8 + 2(8)

a) The cost of an apple 50p.

b) The cost of an apricot is 43p

The cost of something depends on a variety of factors, including the quality of the product, the quantity desired, the availability of the item, the location of the purchase, and the method of payment. For example, a computer may cost more if purchased at a retail store than it would cost if purchased online. Additionally, the cost of a product can vary depending on the brand, features, and other factors. For example, a laptop may be more expensive if it has a faster processor than one with a slower processor. In general, the cost of a product or service will also depend on the demand for it, as well as the amount of competition in the marketplace. Ultimately, the cost of something is determined by the value the customer places on it.

Cost of 6 apples = £3

Mean = Sum of Values / Number of Values

Given data ,

Let the mean of p , g and r be represented as M

Now , the mean of p and g = 13

So , ( p + g ) / 2 = 13

On simplifying the equation , we get

p + g = 26   be equation (1)

Step-by-step explanation:

Find the limits using μ ± 3σ  and μ ± 2σ

Using μ ± 3σ

Upper Control Limit = μ +  3σ = 16.8 + 3(0.7)= 16.8 + 2.1= 18.9

Lower Control Limit = μ - 3σ =16.8 - 3(0.7)= 16.8 - 2.1= 14.7

Using μ ± 2σ

Upper Control Limit = μ +  2σ = 16.8 + 2(0.7)= 16.8 + 1.4= 18.2

Lower Control Limit = μ - 2σ =16.8 - 2(0.7)= 16.8 - 1.4= 15.4

The data points are 17.3, 14.9, 18.3, 16.5, 16.1, 17.4, 18.4.

Rearranging these data points  14.9, 16.1, 16.5, 17.3, 17.4, 18.3,18.4.

In correlational and experimental study designs, a key requirement for a sample is that population whom the researchers are investigation

A sample is a portion of a larger population that is selected to represent the entire group. In both correlational and experimental study designs, a key requirement for a sample is that it should be representative of the population it is meant to represent.

In a correlational study design, the goal is to examine the relationship between two or more variables. The sample must be representative of the population to ensure that the correlation calculated from the sample is representative of the correlation that exists in the population.

If the sample is not representative, the correlation calculated from the sample may be different from the correlation that exists in the population, leading to incorrect conclusions.

In an experimental study design, the goal is to test a causal relationship between two or more variables.

The sample must be representative of the population to ensure that the results of the experiment are generalizable to the population.

If the sample is not representative, the results of the experiment may not be generalizable to the population, leading to incorrect conclusions.
