Is 10000000000, 10 to the power of 10
It's just an estimate. There's no telling how close it is.
To estimate using just the information in the table,
ASSUME that the average of all the students in each
slot is the average time of that slot.
I know that's confusing. I can't think of a better way to say it,
so here are two examples of what I mean. Look at the table:
-- 6 students said that they spent between 0 and 30 minutes.
ASSUME that those 6 students averaged 15 minutes each.
-- 21 students said that they spent between 60 and 90 minutes.
ASSUME that those 21 students averaged 75 minutes each.
So, when you add up the times for all 50 students, you'll have
(6 x 15 min) + (14 x 45 min) + (21 x 75min) + (9 x 105 min) =
When you total up all those times, divide it by 50 to estimate
the average per student.
Remember ... it's only an estimate.
If the first group had 1 student that spent 2 minutes, and
the other 5 of them spent 29 minutes, then it won't work.
But you'll never know.
Answer:
6/50 simplified to 3/25
Step-by-step explanation:
step 1 Address input parameters & values.
Input parameters & values: The decimal number = 0.12
step 2 Write it as a fraction
0.12/1
step 3 Multiply 100 to both numerator & denominator
(0.12 x 100)/(1 x 100) = 12/100
It can be written as 12% = 12/100 or 12/100
step 4 To simplify 12/100 to its lowest terms, find LCM (Least Common Multiple) for 12 & 100.
4 is the LCM for 12 & 100
step 5 divide numerator & denominator by 4
12/100 = (12 / 4) / (100 / 4)
= 3/25
3/25 is a simplest fraction for the decimal point number 0.12
Answer:
83 m (nearest metre)
Step-by-step explanation:
This can be modeled as a <u>right triangle</u>, where the base is 60 m and the height is the height of the building.
<u>Alternate Interior Angles Theorem (Z-angles)</u>
If a line intersects a set of parallel lines in the same plane at two distinct points, the alternate interior angles that are formed are congruent.
Using the Alternate Interior Angles theorem, the angle between the ground and the dashed line (angle of elevation) is 54°.
<u>Tan trigonometric ratio</u>
where:
is the angle- O is the side opposite the angle
- A is the side adjacent the angle
Given:
- = 54°
- O = height of building (h)
- A = 60
Substituting the given values into the formula and solving for h:
Answer:
The first step is to find a number that when subtracted from 2 gives you 2.
Step-by-step explanation:
The algebraic part of this problem would be to add the -2 (adding 2 to both sides) to both sides, so
first x-2=2, then x-2(+2)=2(+2) which would give us,
x=4
*note: the parenthesis are just to show that we are adding the 2, to make it more understandable.
