A collection of 5 positive integers has mean 4.4, unique mode 3 and median 4. If an 8 is added to the collection, what is the new median. Express your answer as a decimal rounded to the nearest tenth.
9514 1404 393
Answer:
4.5
Step-by-step explanation:
It appears the 5 integers must be {3, 3, 4, 5, 7}.
For the mode to be unique, there must be more than one '3', and there cannot be any other repeated numbers. For 4 to be the median, it must be the 3rd-highest number. Then the remaining numbers must be integers greater than 4 with a sum of 12 for the mean to be 4.4.
When 8 is added to the collection, the median is now the average of 4 and 5, so is 4.5.
The new median is 4.5.

Comment on vocabulary
mean: the sum of numbers divided by the number of numbers. 5 numbers with a mean of 4.4 will have a sum of 5×4.4 = 22.
median: the middle number of a collection of an odd number of numbers, when sorted from lowest to highest. It is the 3rd number of a group of 5 numbers. When there are an even number of numbers in the group, the median is the average of the middle two in the sorted list. Here, that means the 3rd number in the list of 5 is '4'. When 8 is added, 4 becomes one of the numbers contributing to the average that will be the new median.
mode: the member of the group that appears the most times. When the mode is unique, it means there are no other numbers repeated as often. Here, we know the 3rd number (of 5) is 4, so there can only be two numbers '3' in the collection. That 3 is the unique mode means no other numbers are repeated at all.

Convert the following repeating decimal to a fraction in simplest form.
.78
Answer:
78/100
Step-by-step explanation:
Since .78 is in the hundredths place just move the decimal two places to the right then put it over 100. But idk if you mistyped this because .78 is not a repeating decimal
Answer:
6/9
Step-by-step explanation:
Change 0.7878 to a fraction.
Let n = 0.7878... Multiply both sides by 100 (by 100 when there are two repeating decimal digits)
100n = 78.7878... Subtract n from 100n.
99n = 78 Divide both sides by 99
n = 78/99 but n is 0.7878..., so
0.7878... = 78/99
Similarly with 0.66...
Let n = 0.66... Multiply both sides by 10 (by 10 when there is only one repeating digit)
10n = 6.66... Subtract n from 10n.
9n = 6 Divide both sides by 9.
n = 6/9 but n is 0.66..., so
0.66... = 6/9
Roberta bought 9/10 to pound of raisins. She put 2/5 pound in bags for her lunch. How many 2/5-pound bags can Roberta fill? Does she have any left over?
Answer:
2
Step-by-step explanation:
The number of the 2/5-pound bags can Roberta fill will be 2.25.
What is an expression?The mathematical expression is the combination of numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.
Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also be used to denote the logical syntax's operation order and other properties.
Given that Roberta bought 9/10 pounds of raisins. She put 2/5 pounds in bags for her lunch.
The number of bags will be calculated as below:-
Number = ( 9 / 10 ) / ( 2 / 5 )
Number = 2.25
Therefore, the number of the 2/5-pound bags can Roberta fill will be 2.25.

what is the length of x
Answer:
x = 15
Step-by-step explanation:
Since the triangles are similar, then the ratios of corresponding sides are equal, that is
[tex]\frac{9}{3}[/tex] = [tex]\frac{x}{5}[/tex] ( cross- multiply )
3x = 45 ( divide both sides by 3 )
x = 15
