What is 4c minus 7.8 if c is 4

1 answer:

5 0

Here is a substitution problem. By saying c is 4, we can replace anywhere we see c with the number 4.

c = 4

4c - 7.8
= 4(4) - 7.8
= 16 - 7.8
= 8.2

Hope this helps! :)

Answer:

d, e

Step-by-step explanation:

The applicable rules of exponents are ...

(a^b)(a^c) = a^(b+c)

a^-b = 1/a^b

In this case, it means the product is ...

(6^1)(6^0)(6^-3) = 6^(1+0-3) = 6^-2 = 1/6^2 = 1/36

The 6 without an exponent is equivalent to 6^1, an exponent of 1.

The sum of the exponents is -2.

Add the exponents to simplify the expression.

The value of the expression is 1/36.

An equivalent is any expression that results in 6^-2. One such is (6^5)(6^-7).

Only the last two choices, d and e, apply.

sasho [114]

Answer:

Note: The full question is attached as picture below

1. The manufacturer is taking a sample of her friends, which is most convenient to sample - Convenience sampling

2. The whole population is divided into different groups (strata) and random samples are drawn from each group - Stratified sampling

3. The population is divided into different clusters (here, communities) and whole clusters are surveyed - Cluster sampling

4. The samples are drawn at a fixed interval from the population list - Systematic sampling

5. The samples are randomly drawn from the population - Simple random sampling

What do outliers, mean, median, mode, and range tell you PLEASE SHOW EXAMPLES!!!!!!

Hello there!

Outlier is a value in a data set that varies significantly from the rest of the data.

Example: Way too low: 1, 45, 58, 60, 63, 75

Outlier = 1

Way too high: 4, 3, 2, 21, 7

The number should be the order from least to greatest are: 2, 3, 4, 7, 21.

Outlier = 21

It impact the mean and the median in different ways.

Data with no outlier: 4, 5, 7, 11, 12, 15

54÷6=9

Mean = 9

Data with an outlier: 4, 5, 7, 11, 12, 15, 58

112÷7=16

Mean = 16

Median is the middle value in an ordered list of numbers.

Example:

Numbers already in order:

1, 5, 8, 10, 13

Numbers not already in order:

13, 1, 5, 10, 8

1, 5, 8, 10, 13, 15

8+10=18 or 18÷2=9

Median =9

Range is a difference between the maximum (highest) and minimum (lowest) values. It has one type of measure of spread.

Example:

Data in order: 23, 27, 39, 53, 62, 84

84-23=61

Data not in order: 272, 52, 67, 201, 43, 256

272-43=229

Hope this helps! Thank you for posting your question at here on Brainly.
