Answer:
0.10 or 10%
Step-by-step explanation:
Since each student must take at least 2 courses, if no student took all three courses, the sum of the percentages would total 200% (counting each student twice). Therefore, the proportion of students taking all three courses is the difference between the sum of all percentages and 200%:

0.10 or 10% of the students take all 3 courses.
The correct answer is C) (5×10⁴)(1×10²)
Explanation:
The number of trees can be calculated by the formula:
trees = density × area
Consider that the problem says that the researcher makes an approximation, and the answers have numbers written in scientific notation.
The density is 86 trees/km²,
which can be rounded to 100 trees/km²
and written as <span>1×10².
Therefore, density = </span>1×10² trees/km²
The area of a square can be calculated by the formula:
A = s²
= 220²
= 48400 km²
which can be roundend to 50000
and written as <span>5×10⁴
Therefore, area = </span>5×10⁴ km²
Now, we can substitute in the original formula:
trees = (1×10²)(5×10⁴)
Answer:
PROPORTION.
Step-by-step explanation:
The relative frequency in a relative frequency histogram refers to PROPORTION.
A relative frequency histogram uses the same information as a frequency histogram but compares each class interval with the number of items. The difference between frequency and relative frequency histogram is that the vertical axes uses the relative or proportional frequency rather than simple frequency
It's easier to add these first and then change to SN.
41,300,000 + 50,500,000 = 91,800,000
SN needs to change to this format:
9.18 x 10^7
