Step-by-step explanation:
To find the new price of the sneaker, you would multiply 54.00 by 1.25. (it's 1.25 because to do percents you would divide them by 100 to put them in decimal form.)
Answer:
v = 15/7, or 2.14
Step-by-step explanation:
Find a common denominator, or multiply both denominators by each other, and well as the numerator.
v/5 = 3/7 can be written as 7v/35 = 15/35
multiplying both sides with 35, we are left with 7v = 15
v = 15/7, or 2.14
Because it shows how Alabamians lived in 19th to the mid 20th century, and buildings that were safe from destruction.
There are 72 tokens with Riley and 63 tokens with Erik
<em><u>Solution:</u></em>
Riley and Erik have earned a total of 135 tokens to buy items in the school store
Total number of tokens = 135
The ratio of the number of tokens that Riley had to the number of tokens that Erik has is 8 to 7
Number of tokens with Riley : Number of tokens with Erik = 8 : 7
Let the number of tokens with Riley be 8x
Let the number of tokens with Erik be 7x
Since, Total number of tokens = 135
number of tokens with Riley + number of tokens with Erik = 135
8x + 7x = 135
15x = 135
x = 9
Therefore,
Number of tokens with Riley = 8x = 8(9) = 72
Number of tokens with Erik = 7x = 7(9) = 63
Thus there are 72 tokens with Riley and 63 tokens with Erik
Answer:
1. A) the data is more spread out
2. C) the data is less spread out
Step-by-step explanation:
1) Standard Deviation is a measure of dispersion, denotes the spread of data around measure of central tendency (usually arithematic mean).
A data set with higher standard deviation implies A) Data is more spread out or scattered, & vice versa less spread for less standard deviation.
2) Interquartile range is also a measure of dispersion, denoting difference between Q1 (25th percentile) & Q3 (75th percentile).
A data set with smaller interquartile range implies C) Data is less spread out, & vice versa more spread for higher interquartile range.
