**Answer 1**

**Answer:**

[tex]\frac{2}{5}[/tex] and [tex]\frac{2}{7}[/tex]

**Step-by-step explanation:**

We want to work backwards. Currently we have [tex]\frac{ }{ }[/tex][tex]\frac{?}{?}[/tex] ÷ 5 = [tex]\frac{2}{25}[/tex].

If we **multiply both sides by 5**, we get [tex]\frac{?}{?}[/tex] = [tex]\frac{2}{25}[/tex] × [tex]\frac{5}{1}[/tex].

We can use **multiplication of fractions** to solve this. To multiply fractions we **multiply **the **two numerators together** and **multiply **the **two denominators together**, giving an answer of [tex]\frac{?}{?}[/tex] = [tex]\frac{10}{25}[/tex].

This can be **simplified **to [tex]\frac{2}{5}[/tex].

We can use the **same method** on the other equation to get an answer of [tex]\frac{2}{7}[/tex].

I’m confused with this question, so I can’t find the median because there is repeating numbers so yeah

### Answers

Answer:

60

Step-by-step explanation:

To find the mean, add all numbers together and divide by the amount of numbers.

Total of number = 660

Number of numbers = 11

660/11 = 60

**Answer:**

The median is 70.

**Step-by-step explanation:**

I believe you may have mixed up median with mode.

Here are the definitions of both:

**Mode** - The value that appears the most in a data set

**Median** - The middle number in a list of numbers ordered from least to greatest

To find the median of this data set, we must arrange the numbers from least to greatest!

20, 20, 30, 50, 60, 70, 70, 80, 80, 90, 90

Now we just have to figure out the middle number...which is 70!

20, 20, 30, 50, 60,** 70**, 70, 80, 80, 90, 90

what is the purpose of a statistical control chart?

### Answers

A statistical control chart compares process performance data to computed "statistical control limits," which are represented on the chart as limit lines. Process performance data are typically composed of groups of measurements (rational subgroups) from the regular sequence of production while maintaining the data's order.

The **statistical control chart** is discussed below.

What is statistics?Statistics is the discipline that concerns the **collection, organization, analysis, interpretation**, and **presentation** of data. In applying statistics to a scientific, industrial, or social problem, it is conventional to begin with a statistical population or a statistical model to be studied.

Given is the** statistical control chart**.

The control chart is a graph used to study how a **process changes **over time. Data are plotted in time order. A control chart always has a **central line** for the average, an upper line for the** upper control limit**, and a lower line for the **lower control limit**. These lines are determined from historical data.

Parts of a control chart -Points representing a statistic (e.g., a mean, range, proportion) of measurements of a** quality characteristic** in samples taken from the process at different times (i.e., the data)The **mean** of this statistic using all the samples is calculated (e.g., the mean of the means, mean of the ranges, mean of the proportions) - or for a **reference period** against which change can be assessed. Similarly a median can be used instead.A **centre line **is drawn at the value of the mean or median of the statistic**Upper control** and **lower control** limits (sometimes called "natural process limits") that indicate the threshold at which the process output is considered statistically 'unlikely' and are drawn typically at 3 standard deviations from the center line.

Therefore, the **statistical control chart** is discussed above.

20) 7/16 = 0.4375

21) 1/6 = 1.6 repeating

22) 2 4/5 = 2.8

23) 98 2/3 = 98.6 repeating

24) 0.8 = 4/5

25) 26 1/5

26) 72.1 repeating = 72 1/9

27) 0.505 = 101/200

**Explanation:**

To convert fraction into decimal, divide the numerator by the denominator and that's your answer. For example:

7 ÷ 16 = 0.4375.

To convert a decimal into a fraction, place the number after the decimal point over the number place it's in. For example: If you look at 0.8 , 8 is in the tenths place, so you place it over 10 like this 8/10, and then you simplify. Half of 8 is 4 , and half of 10 is 5, so you'd have 4/5.

For #27, since 505 in 0.505 , is in the thousandths place, you'd put it over 1,000 like this 505/1000 and then you simplify. Look at image above to learn how to simplify 505/1000.⤴⤴⤴

On a family vacation, Aaron took 1,276 digital photos. His twin sister Ashley took 4 times as many as Aaron. Write and solve an equation to find p, the number of photos that Ashley took

### Answers

**Answer:**

Equation : 4(1,276) = p

That means that Ashely took 5104 pics.

**Step-by-step explanation:**

Before we come up with an equation we can solve the problem and see how we solved it. If Aaron had 1,276 pics and his sister took 4 times that, we would multiply 1,276 by 4 to get how many his sister took. We don't need to do the math, but that's how we would solve it. So to find p, or Ashely's amount of pics, it's just 1,276 times 4 = p

Equation : 4(1,276) = p

That means that Ashely took 5104 pics.
