Step-by-step explanation:

Answer: It is linear

Step-by-step explanation:

When you graph the equation, it is a straight line, meaning it is linear.

If you graphed the equation and it wasn't a straight line, it would be nonlinear.

Answer:

\(7y=-5x-11\)

Step-by-step explanation:

Since it says the lines are parallel both of their gradients will be same.

so gradient of line 1 = \(y=\frac{14-5x}{7}\) = \(y=\frac{14}{7}-\frac{5x}{7}\)= \(-\frac{5}{7}\)

so equation of line 2 = \(y-y_{1}=m(x-x_{1} )\)

                                   = \(y-(-3)_{}=\frac{-5}{7} (x-(-2)_{} )\)

                                   = \(y +3=-\frac{5}{7}x+\frac{10}{7}\)

                                   = \(y =-\frac{5x+10}{7}-3\)

                                   = \(7y=-5x-11\)

Step-by-step explanation:

basically a line equation typically looks like

y = ax + b

with a being the slope, and b bent the y-intercept (y value when x = 0).

5x + 7y = 14

7y = -5x + 14

y = -5/7 x + 14/7 = -5/7 x + 2

so, wie know the slope of the original line : -5/7 .

any line parallel to it must have the same slope.

our desired line looks like

y = -5/7 x + b

to get b we use the provided point (-2, -3).

-3 = -5/7 × -2 + b = 10/7 + b

-21/7 = 10/7 + b

-31/7 = b

and the full equation is

y = -5/7 x - 31/7

7y = -5x - 31

5x + 7y = -31

The probability that the mean battery life would be greater than 1173.8 minutes is 0.9588

We can solve this problem using the central limit theorem, which tells us that the distribution of sample means from a population with a known variance becomes approximately normal as the sample size increases.

The standard error of the mean can be calculated as

SE = σ / sqrt(n)

where σ is the population standard deviation, n is the sample size

Here, we are given that the population variance is 8100, so the population standard deviation is the square root of 8100, which is 90.

SE = 90 / sqrt(72) = 10.6066

Next, we need to standardize the sample mean using the z-score formula

z = (X - μ) / SE

where X is the sample mean, μ is the population mean.

Here, the population mean is given as 1192 minutes and the sample mean we are interested in is 1173.8 minutes.

z = (1173.8 - 1192) / 10.6066 = -1.7356

We want to find the probability that the sample mean is greater than 1173.8 minutes. Since we have a negative z-score, we need to find the area to the right of this value on a standard normal distribution. We can use a z-table or a calculator to find this probability.

Using a standard normal distribution table, we find that the area to the right of z = -1.7356 is 0.9588.

Cumulative frequency for a weight of 27.5 pounds is 42.

1. First, arrange the data in ascending order.

2. Identify the weights given and their corresponding frequencies.

3. Calculate the cumulative frequency by adding up the frequencies for weights less than or equal to 27.5 pounds.

4. In this case, the cumulative frequency for 27.5 pounds would be the sum of the frequencies for all weights less than or equal to 27.5 pounds.

5. If the given data is in a frequency table, simply find the cumulative frequency value corresponding to the weight of 27.5 pounds.

6. If the data is not given in a frequency table, you can create one by counting the occurrences of each weight and then calculating the cumulative frequencies.

7. Once you have the cumulative frequencies for all weights, find the value corresponding to 27.5 pounds.

8. The obtained value is the cumulative frequency for a weight of 27.5 pounds.

The numerical or verbal descriptions that usually result from measurements are called data or observations.

When measurements are conducted, whether in scientific experiments, surveys, or other data collection processes, the outcome is typically a set of data or observations.

These measurements can be represented numerically, such as numerical values or quantities, or verbally, using descriptive terms or categories.

Numerical descriptions provide precise quantitative information, such as measurements of length, weight, temperature, time, or any other measurable attribute. These measurements are often expressed using numbers or units of measurement.

Verbal descriptions, on the other hand, use words or qualitative descriptions to convey information about the observations.

For example, when conducting a survey, respondents might provide verbal responses that describe their opinions, preferences, or experiences.

Both numerical and verbal descriptions play important roles in data analysis and interpretation.

The amount of money Candy started with after spending on drinks and cakes is £7.95

She bought a drink for £1.45 and a piece of cake for £1.20.

She has two thirds of here money left.

Let the money she has initially  = x

Therefore,

2 / 3 x = x - 1.45  - 1.20

2 / 3 x = x - 2.65

subtract x from both sides

2 / 3 x - x = - 2.65

2x - 3x / 3 = - 2.65

- x / 3 = - 2.65

cross multiply

-x = - 2.65 × 3

- x = -7.95

x = £ 7.95

Step-by-step explanation:

let's name the variables for the age of the people as the people themselves :

orlando = omar + 12

carl = 3×orlando

carl + orlando + omar = 68

using the first equation in the second equation, and then that result and the first equation in the third equation :

carl = 3×(omar + 12)

3×(omar + 12) + (omar + 12) + omar = 68

3×omar + 36 + omar + 12 + omar = 68

5×omar + 48 = 68

For hotels in New York City, a travel web site wants to provide information comparing hotel costs (high, average, low) versus the quality ranking of the hotel (excellent, good, fair, poor). A useful way to summarize these data is to construct a scatter plot.

A scatter plot is a graph that shows the correlation between two variables. A horizontal x-axis and a vertical y-axis are used to plot data points in a scatter plot. Each data point represents a single observation on both the x-axis and the y-axis, and each point on the scatter plot represents a single observation.

The data set, including hotel costs and quality rankings, would be plotted on a scatter plot. The data is plotted using the independent variable on the x-axis and the dependent variable on the y-axis. The data points are spread over the plot in a scattered pattern.

For example, the independent variable is hotel costs, and the dependent variable is quality rankings in this example. A scatter plot is a helpful tool for identifying trends and predicting outcomes. To make sense of the data, a scatter plot can be used to generate a trend line that connects the data points. The trend line is also referred to as a regression line and is used to predict future values of the dependent variable based on the independent variable.

Number of miles a car travels are 28.

The division is the process of repetitive subtraction. It is the inverse of the multiplication operation. It is defined as the act of forming equal groups. While dividing numbers, we break down a larger number into smaller numbers such that the multiplication of those smaller numbers will be equal to the larger number taken.

Number of gallons of gas = 20

A car with 20 gallons of gas can drive 560 miles

Based on the given conditions,

= \(\frac{560}{20}\)

= 28
