The total number of defective iphones from a batch of 16,530 iphones is equal to 513 .

Total  number of iphones examined by quality-control inspector =290

Total number of iphones in a batch = 16,530

Number of iphones defective out of 290 = 9

Let us consider x be the number of defective iPhones in the batch of 16,530 iPhones.

Use proportions to find out how many defective iPhones there will be in a batch of 16,530 iPhones.

The proportion of defective iPhones in the sample of 290 iPhones is,

= 9/290

Proportion of defective iPhones in a batch of 16,530 iPhones,

Set up a proportion,

9/290 = x/16530

To solve for x, we can cross-multiply,

⇒ 9 x 16530 = 290 x

⇒ 148,770 = 290 x

⇒ x = 513

Therefore, there will be approximately 513 defective iPhones in a batch of 16,530 iPhones.

Answer:

f(4) = 5

Step-by-step explanation:

functions are represented by f(x), so x should be the value in parenthesis and the y value should be what it equals

1) Point-slope form: y + 3 = -3(x - 7) and Slope-intercept form: y = -3x + 16

2) Point-slope form: y + 4 = -1/4(x + 3) and Slope-intercept form: y = -1/4x - 19/4

3) Point-slope form: y + 1 = -7(x + 1) and Slope-intercept form: y = -7x - 6

4) Point-slope form: y - 9 = 4(x + 3) and Slope-intercept form: y = 4x + 21

5) Point-slope form: y - 7 = 4(x - 2) and Slope-intercept form: y = 4x - 1

1) Passing through (7,-3) and perpendicular to the line whose equation is Y = (1/3)x + 5.

To find the equation of a line perpendicular to another line, we need to take the negative reciprocal of the slope of the given line. The given line has a slope of 1/3, so the perpendicular line will have a slope of -3 (negative reciprocal of 1/3).

Point-slope form:

Using the point-slope form, where (x₁, y₁) is the given point (7,-3), and m is the slope (-3):

y - y₁ = m(x - x₁)

y + 3 = -3(x - 7)

Slope-intercept form:

To convert the equation to slope-intercept form (y = mx + b), we simplify the equation:

y + 3 = -3x + 21

y = -3x + 18

2) Passing through (-3,-4) and perpendicular to the line whose equation is Y = -4x + 4.

Again, we find the slope of the given line, which is -4, and take its negative reciprocal to get the slope of the perpendicular line, which is 1/4.

Point-slope form:

Using the point-slope form, with (x₁, y₁) as (-3,-4) and m as 1/4:

y - y₁ = m(x - x₁)

y + 4 = 1/4(x + 3)

Slope-intercept form:

Simplifying the equation:

y + 4 = 1/4x + 3/4

y = 1/4x - 13/4

3) Slope = -7 passing through (-1,-1).

Using the point-slope form, with (x₁, y₁) as (-1,-1) and the given slope of -7:

y - y₁ = m(x - x₁)

y + 1 = -7(x + 1)

Slope-intercept form:

Simplifying the equation:

y + 1 = -7x - 7

y = -7x - 8

4) Slope = 4 passing through (-3,9).

Using the point-slope form, with (x₁, y₁) as (-3,9) and the given slope of 4:

y - y₁ = m(x - x₁)

y - 9 = 4(x + 3)

Slope-intercept form:

Simplifying the equation:

y - 9 = 4x + 12

y = 4x + 21

5) Slope = 4 passing through (2,7).

Using the point-slope form, with (x₁, y₁) as (2,7) and the given slope of 4:

y - y₁ = m(x - x₁)

y - 7 = 4(x - 2)

Slope-intercept form:

Simplifying the equation:

y - 7 = 4x - 8

y = 4x - 1

These are the detailed solutions for finding the equations of the lines in point-slope form and slope-intercept form based on the given conditions.

Answer:

9 feets

Step-by-step explanation:

From the question, we have our scale factor as:

4:9 = 4/9

Smaller circle /Bigger circle = 4/9

A circle has a radius of 4 feet. What is the radius of a bigger circle?

Let the radius of the bigger circle = x

This is calculated as:

4/9 = 4/x

Cross Multiply

4x = 9 × 4

x = 36/4

x = 9 feet

Therefore, the radius of the bigger circle is 9 feet

Answer:

n = 9 \(\frac{1}{3}\)

Step-by-step explanation:

First, let's write an equation to show this statement, using a variable N for the number.

3n - 9 = 19

Now to isolate variable N, add nine to both sides to cancel out.

3n = 19 + 9

Simplify.

3n = 28

Now we can divide both sides by three to get our answer.

n = 9 \(\frac{1}{3}\)

The correct interpretation of the 95% confidence interval is: "We estimate with 95% confidence that the true population proportion of people who own a tablet computer is between 0.62 and 0.78."

This means that if we were to repeat the survey many times and construct a confidence interval for each sample, 95% of those intervals would contain the true proportion of people in the population who own a tablet computer. The interval (0.62, 0.78) is the range of values that is likely to contain the true population proportion with 95% confidence, based on the sample data.

Hence, the correct interpretation of the 95% confidence interval is:

Using the given set of scores, let's find the set that has the smallest standard deviation.

The standard deviation shows the dispersion of the dataset from its mean.

We have the following:

• A. 126, 129, 131, 134

Let's find the mean:

When describing the central tendency for qualitative data, the measure that is commonly used is the mode.

Unlike quantitative data, where measures such as the mean or median can be used to describe central tendency, qualitative data consists of categories or labels rather than numerical values.

Therefore, the mode is the most appropriate measure for central tendency in this context.

The mode can be useful in summarizing qualitative data by identifying the most common category or response. It provides insight into the most prevalent characteristic or attribute among the data, allowing for a better understanding of the distribution and patterns within the dataset.

The negative correlation coefficient of -0.73 between consumption of vitamin A and the cancer rate of a particular type of cancer suggests that as vitamin A consumption increases, the cancer rate tends to decrease.

A correlation coefficient measures the strength and direction of the linear relationship between two variables.

In this case, a correlation coefficient of -0.73 indicates a negative correlation between consumption of vitamin A and the cancer rate.

Interpreting this correlation, it can be inferred that there is an inverse relationship between the two variables. As consumption of vitamin A increases, the cancer rate tends to decrease.

However, it is important to note that correlation does not imply causation.

It would be incorrect to conclude that consuming more vitamin A causes this type of cancer. Correlation does not provide information about the direction of causality.

Other factors and confounding variables may be involved in the relationship between vitamin A consumption and cancer rate.

To establish a causal relationship, further research, such as experimental studies or controlled trials, would be necessary. These types of studies can help determine whether there is a causal link between vitamin A consumption and the occurrence of this particular cancer.
