The answer is -12. Do you need to know how I did it?
The answer is 50 and 24
The two equations are x + 2y = 98 and x = 3y - 22
every answer equals 98 when you use the first equation but the only one that works with the second equation is C (works meaning when you plug in the answers from the answer choices)
x = 3(24) - 22
x = 50
Hi There!
Donna needs to memorize words on a vocabulary list for Korean class. She has memorized 36 of the words, which is three-fourths of the list. How many words are on the list
36 / 3 = 12
12 * 4 = 48
There are 48 words on the list.
Hope This helps :)
Answer:
The answer would be 12x
Step-by-step explanation:
You have to add all the sides together because its a square and all sides are equal. So 3x+3x+3x+3x equals 12x
The true statements are:
A. Tree A's heights are less spread out than tree B's heights and
B. Tree A has lower average height than tree B
Explanation:
Standard deviation in this case represents the spreading out of heights of the trees, Since tree A has lesser standard deviation given equal to 5 , it is less spread out than B given equal to 12, hence option A. is true.
The average of a quantity is given by mean so, the average height can be compared by the given mean values of the trees. Since, A has lesser mean value (= 25) than B(=60), tree A is said to have lower average height than tree B hence option B. is true.
