Answer:

It is 1 cent cheaper  to pay 5.46 for 7 apples.

Step-by-step explanation:

Find the unit rate:

5.46 /7 = 0.78

This is the cost for 1 apple

3.95/5 = 0.79

This is the cost for 1 apple

Answer:

5 apples for 3.95 is the better deal

Step-by-step explanation:

If you divide 7 by 5.46 you should get roughly 1.28, so $1.28 per apple

and if you divide 5 by 3.95 you should get roughly 1.26, meaning $1.26 per apple. You can verify this by multiplying 1.26 by 5 and 1.28 by 7

A subset of a population used by statisticians to make predictions about a population is called a sample.

a sample is a smaller, representative group selected from the larger population. The sample is used to gather data and make inferences about the entire population. By analyzing the sample, statisticians can make predictions about the characteristics, trends, or behaviors of the population without having to study every individual within it. This method saves time, resources, and effort while still providing accurate results.

A sample is a crucial tool in statistical analysis, allowing statisticians to make informed predictions about a population based on the study of a smaller, representative subset.

64 observations were randomly selected at random from a population of 500. the population standard deviation is 16.The standard deviation of the sample mean is 4 (16/√64).

The standard deviation of the sample mean is calculated by dividing the population standard deviation (16) by the square root of the sample size (64).

Consequently, the sample mean's standard deviation is

16/√64 = 4.

This means that the expected spread of the sample means is 4, which is less than the population standard deviation of 16. This is because the sample is smaller than the population, so the sample standard deviation will be smaller than the population standard deviation.

The value of x = 16, y = 172 and z = 2.

x - 4z = 12x - y - 6z = 42x + 3y - 2z = 8

let x - 4z = 8 be equation (1), 12x - y - 6z = 8 be equation (2) and 42x + 3y - 2z = 8 be equation (3)

x - 4z = 8

x = 8 + 4z

12x - y - 6z = 8

12(8 + 4z) -y - 6z =8

96 + 48z - y - 6z = 8

42z - y = -88

y = 42z + 88

42x + 3y - 2z = 8

42(8+4z) + 3(42z + 88) - 2z = 8

336 + 168z + 126z + 264 - 2z = 8

168z + 126z + 2z = 336+264 - 8

296z= 592

z = 2

substituting the value of z

x = 8 + 4z

= 8 + 4(2)

8+8 = 16

y = 42z + 88

Superior segway tours provide sightseeing tours around chicago, illinois. it charges a one-time fee of $55 with $15 per hour.  The slope of the situation is 15.

The slope of a situation represents the rate of change of one quantity with respect to another. In this case, the quantity being considered is the cost of the sightseeing tour, and the independent variable is the number of hours the tour lasts. The cost of the tour can be expressed as a linear equation: C = 55 + 15h, where C is the cost and h is the number of hours. The slope of this equation is 15, meaning that for every hour the tour lasts, the cost increases by $15.

Step-by-step explanation:

Let the sides of the parallelogram be x and (x + 10) cm

Perimeter of parallelogram = 140 cm

\(2 \{x + (x + 10) \} = 140 \\ \\ \{x + x + 10 \} = \frac{140}{2} \\ \\ 2x + 10 = 70 \\ \\ 2x = 70 - 10 \\ \\ 2x = 60 \\ \\ x = \frac{60}{2} \\ \\ x = 30 \: cm \\ x + 10 = 40 \: cm \\ \)

Thus, length of each side of the parallelogram are 30 cm, 40 cm, 30 cm, 40 cm.

The number of kilowatt-hours consumed in a week by the 850-Watt window air conditioner that is left on all day is approximately 14.28 kW-hrs.

To calculate the number of kilowatt-hours (kW-hrs) consumed by the air conditioner in a week, we need to consider the power rating of the air conditioner (850 Watts) and the duration it is left on each day.

Power of the air conditioner = 850 Watts

Duration of usage per day = 24 hours (left on all day)

Number of days in a week = 7 days

To calculate the energy consumption, we can use the formula:

Energy (kW-hrs) = Power (kW) * Time (hours)

First, let's convert the power from Watts to kilowatts by dividing it by 1000:

Power (kW) = 850 Watts / 1000 = 0.85 kW

Now we can calculate the energy consumption in a week:

Energy (kW-hrs) = Power (kW) * Time (hours)

Energy (kW-hrs) = 0.85 kW * 24 hours/day * 7 days

Energy (kW-hrs) = 14.28 kW-hrs

Therefore, the number of kilowatt-hours consumed in a week by the 850-Watt window air conditioner that is left on all day is approximately 14.28 kW-hrs.

Look up the molar masses of each component element:

• Mg : 24.305 g/mol

• S : 32.06 g/mol

• O : 15.999 g/mol

• H : 1.008 g/mol

Then MgSO₄•7H₂O has a total molar mass of about 246.466 g/mol. 7H₂O has a total molar mass of about 126.105 g/mol, so it makes up about 0.5117 or 51.17% of the total mass.

Now, 0.01132 mol of MgSO₄•7H₂O has a mass of

(0.01132 mol MgSO₄•7H₂O) × (246.466 g/mol) ≈ 2.79 g

Univariate and multivariate analysis are broader terms that refer to the analysis of single variables and multiple variables, respectively, and may not specifically address the issue of percentiles of ranked data.

To determine the confidence intervals of percentiles of ranked data, it is most appropriately assessed using nonparametric testing. Nonparametric testing is a statistical method that does not rely on assumptions about the distribution of the data. It is particularly useful when dealing with ranked data, as it does not require the data to follow a specific distribution.

This method allows for the estimation of percentiles and confidence intervals without making assumptions about the underlying distribution. Parametric testing, on the other hand, assumes that the data follows a specific distribution and may not be appropriate for ranked data.

The three conditions for a function to be continuous at a point x=a are:

a) The function is defined at x=a.

b) The limit of the function as x approaches a exists.

c) The limit of the function as x approaches a is equal to the value of the function at x=a.

The continuity of a function can be analyzed by observing its graph. However, as the graph is not provided, a specific discussion about its continuity cannot be made without further information. It is necessary to examine the behavior of the function around the point in question and determine if the three conditions for continuity are satisfied.

The function f(x) = { *** is not defined in the question. In order to discuss its continuity, the function needs to be provided or described. Without the specific form of the function, it is impossible to analyze its continuity. Different functions can exhibit different behaviors with respect to continuity, so additional information is required to determine whether or not the function is continuous at a particular point or interval.
