No, it is not compulsory to do all calculation to find sigh of product
Negative number × odd time = Negative number
Negative number × even time = Positive number number
The constant of proportionality is 5.5
Step-by-step explanation:
y = kx
k = constant of proportionality
y = <u>5.5</u>x
Answer:
x = 27
Step-by-step explanation:
x/9 = 3
Multiply each side by 9
x/9 * 9 = 3*9
x = 27
Answer:
Step-by-step explanation:
Add 25 to both sides:
Square root both sides:
(Since a negative number multiplied by itself gives positive, there are two answers.)
Answer:
<u>If we remove 61 from the data set, the median changes from 87.5 to 93.</u>
Step-by-step explanation:
1. Let's calculate the median of the original data set:
Median = (3rd term + 4th term)/2 because the number of terms are even and our median mark is the average of the two middle marks, in this case, 82 and 93.
Median = (82 + 93)/2
Median = 87.5
2. Let's calculate the median of the data set removing 61:
Median = 3rd term because our median mark is the middle mark, in this case, 93. It is the middle mark because there are 2 scores before it (80 and 82) and 2 scores (94 and 98) after it.
Median = 93
