Well first we need to determine what each choices ( mean, median, mode, interquartile range) means.
Mean- average of a set of numbers
Median - middle number of a set of numbers
Mode- number that appears the most in a set of numbers
Interquartile range- find median of set of numbers and separate the set into 3 equal sections total. Subtract the 3rd section from the 1st section. So you can find the range or span of numbers.
If you want to build an elevator that can hold a maximum of 1,500 pounds, i think the most important fact you need to know about weight is the average weight that all the people weighs so you can know what to expect<span />
Answer:
The temperature needs to decrease 71° - 50° = 21° that at least not greater than 50°F
As we know, the device decrease the temperature down 3.5° every hour, so
21 : 3.5 = 6 hour
Call x is the hours we need to wait to let the device decrease, we have
x > 6
Answer:
70
Step-by-step explanation:
Hey There!
To find the range you subtract the largest number from the smallest number. In this data plot it seems that the largest number is 85 and the lowest number is 15
85-15=70
Therefore the range is 70
Answer:
x = 9
Step-by-step explanation:
You can solve this problem by isolating the variable.
3-√x = 0
√x = 3 (add √x to both sides of the equation)
x = 9 (square both sides of the equation)
B.) thousandths because the first one is tenths and the second is hundredths. Also because it is after the decimal
