The answer is the second option: T<span>wo places left.
Therefore, the complete text is: "</span>To obtain the number of centimeters from a distance measured in meters, move the decimal point Two places left ".
<span>
The explanation is:
1 meter has 100 centimeters, then, if you have a distance of 45.55 centimeters and you want to know this value in meters, you need to divide it by 100 or, in others words, you need to </span>move the decimal point two places left:
<span>
=(45.55 centimeters)(1 meter/100 centimeters)
=(45.55x1)/100
=0.4555 meters

Find the mean for both:
Sierra: 2 + 11 + 12 + 13 + 15 = 53
53/5 =10.6
Median is the middle value = 12
Alek: 9 + 11 + 11 + 12 + 13 = 56
56/5 = 11.2
Median = 11
A: The medians do not equal the mean.
B: Sierra's are more spread out, ( no identical ages and a greater range ).
C: Sierra's mean is less than Alek.
D. Sierra has an outlier (2).
The answer would be B
Answer:
B) 7 cans
Step-by-step explanation:
First task is to determine how many square units we have.
With the rectangle spanning 2 units on the X-axis and 3 unites on the Y-axis, we know that it has an area of 6 square units.
The two triangle shapes sum up to one unit total, since a triangle's area is (base * height) / 2. Both have a base of 1 unit, and a height of 1 unit... so (1 * 1) / 2 = 1/2 for each triangle. Together, they occupy 1 unit.
So, total is 7 square units. Let's imagine it as a 7-unit by 1-unit rectangle, it will be easier to calculate. Each unit is 5 feet. So, this rectangle measures 35 (7 * 5) feet long, by 5 (1 * 5) feet wide... for a total of 175 (35 * 5) sq feet.
Since a can of paint can cover 25 sq feet, he'll need 7 cans (175 / 25).
Answer:
99 marks
Step-by-step explanation:
Given:
Juan received scores of 82, 76, 93, and 80 on his first four chemistry tests.
His goal is to have an 86 average in chemistry for his first five tests.
Question asked:
What score must he earn on the next test to achieve an average of exactly 86?
Solution:
Let score he must earn on the fifth test = 
As we know:
Scores in five test = 82, 76, 93, 80,
Total number of test = 5
<u>We can find the score of fifth test, he must earn to achieve an average of exactly 86 by using this formula:</u>
By cross multiplication
Subtracting both sides by 331
Therefore, he must earn 99 marks to achieve an average of exactly 86 for his first five tests in chemistry.
