Answer:
Hi!
The answer is: William needs to put 14 signs more.
Step-by-step explanation:
To solve this problem, you can use the rule of three.
1/16 ----> 1 sign // If for every 1/16 miles needs is 1 sign.
7/8 ----> x signs // then 7/8 miles will need x signs.
Now, multiply 7/8 by 1 and divide the result by 1/16:
// reverse the numerator and denominator of the second fraction and multiply.
William should put up 14 more signs.
what is the best measure of center for this data set (FQ, mean, median, or range) , and its value is (3, 4, 4.5, or 6.8)
Answer: The best measure of center for this data set is median , and its value is 4.5 .
Step-by-step explanation:
The given data set : {5, 3, 5, 30, 4, 5, 4, 3, 4, 5}
We can see that it has an outlier (i.e. 30) which is extremely large from all the values.
We know that to measure the center of tendency we measure one of three things arranged in ascending order:
Mode< Median <Mean
But mean gets affected by outlier value.
Then the best measure of center for this data set must be Median.
For this, arrange given data set in order:
{3 ,3 ,4 ,4 ,4 ,5 ,5 ,5 ,5 ,30 }
Since , the number of data values = 10 (even)
Then , Median = Mean of two middle most numbers
Hence, the best measure of center for this data set is median , and its value is 4.5 .
The expression for the inequality is written as a > 200.
When two expressions are connected by a sign like "not equal to," "greater than," or "less than," it is said to be inequitable. The inequality shows the greater than and less than relationship between variables and the numbers.
Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.
Given that each day, the cafeteria serves more than 200 apples with lunch.
The inequality will be written as,
a > 200

Answer:
The correct answer is: c) 75% of the data is less than 45
Step-by-step explanation:
x = 45 has a percentile rank of 75%, Percentile rank represents the percentage of data points that fall below a given value. In this case, 75% of the data falls below the value of 45. This means that 45 is greater than 75% of the data points. Options a) and b) can be ruled out because the given information does not provide any indication about the skewness or distribution of the data. Option d) is incorrect because the percentile rank of 75% indicates that 75% of the data is less than the given value (in this case, 45), not greater.
