Your answer would be 107. You can get this answer by following the rules of PEMDAS or Parentheses,Exponents,Multiplication, Division, Addition and Subtraction. Hope this helps! :D
Answer:
2 3/5 in decimal form will look like this.
2.6
Answer:
1.- If a number can be written or can be converted to p/q form, where p and q are integers and q is a non-zero number, then it is said to be rational and if it cannot be written in this form, then it is irrational.
2.- The square root of a number is that number which when multiplied by itself two times gives us that number.
Example:
Let us use the square root of 64.
√64 = x , so that (x)(x) = 64
We know that, (8)(8) = 64
∴ √64 = 8
The cube root of a number is that number which when multiplied by itself three times gives us that number.
Example:
Let us use the square root of 64
∛64 = x , so that (x)(x)(x) = 64 ,
We know that, 4 x 4 x 4 = 64
∴ ∛64 = 4
Answer:
Step-by-step explanation:
c + f = 10 (the coach tickets + first class tickets = 10)...there is 10 people
160c + 1230f = 6950....each coach ticket is 160 and each first class ticket is 1230.....and when added, they equal 6950 (for the airfare)
c + f = 10.....c = 10 - f
160c + 1230f = 6950
sub in 10 - f for c
160(10 - f) + 1230f = 6950
distribute the 160 thru the parenthesis
1600 - 160f + 1230f = 6950
combine like terms
1600 + 1070f = 6950
subtract 1600 from both sides
1070f = 6950 - 1600
1070f = 5350
divide both sides by 1070
f = 5350/1070
f = 5 <===== she bought 5 first class tickets
c + f = 10
we found f to be 5...so sub in 5 for f and find c, the coach tickets
c + 5 = 10
c = 10 - 5
c = 5 .......and she bought 5 coach tickets
check...
160c + 1230f = 6950
160(5) + 1230(5) = 6950
800 + 6150 = 6950
6950 = 6950 (correct)....so it checks out
5 coach and 5 first class
The better statistics that can be used to compare the scores of the two teams are: <u>D. Median and IQR.</u>
- The diagram given shows two box plots representing the data of the two team's scores.
<u><em>Box plots</em></u><u><em> displays the </em></u><u><em>5-number summary</em></u><u><em>, namely:</em></u>
- Minimum data value
- Maximum data value
- Median
- First Quartile
, and - Third Quartile
The Interquartile Range (IQR) of the data can also be calculated by finding the difference between the First Quartile , and the Third Quartile .
The Interquartile Range (IQR) helps us to determine the variability of the data set.
The median that is gotten from the box pot measures the center tendency of the data.
Both median and IQR are better statistics that can be easily gotten from box plots to compare the team scores.
Therefore, the better statistics to use for comparing the scores of the teams are: <u>D. Median and IQR.</u>
