Answer:
8/3
Step-by-step explanation:
Because all 4 angles are congruent, the sides are proportional.
the scale factor is 5/30 = 1/6.
meaning x = 16(1/6)=8/3.
Answer:
x = 72 , y = 108
Step-by-step explanation:
2x and 
are adjacent angles on a straight line and sum to 180° , that is
2x + = 180 ( multiply through by 2 to clear the fraction )
4x + x = 360
5x = 360 ( divide both sides by 5 )
x = 72
--------------------------
= 
= 36
and 
are vertically opposite and are congruent , then
= 36 ( multiply both sides by 3 )
y = 108
Answer:
- <u>Option</u><u> </u><u><em>A</em></u><em>. If percentages are used, the sum should be a 100%. If proportions are used, the sum should be 1.</em>
Explanation:
The <em>relative frequency</em> can be measured as a ratio (proportion) or as a percentage.
As a ratio, the relative frequency is the number of times that the desired outcome is observed (either theoretically or experimentally) divided by the total number of possible outcomes (theoretically) or observed (experimentally).
As a<em> percentage</em>, the relative frequency is the ratio multiplied by 100.
This shows it mathematically:
- relative frequency of event 1 = frequency of event 1 / number of events
- relative frequency of event 2 = frequency of event 2/number of events
- relative frequency of event n = freqquency of event n/number of events
- Total relative frequency = sum of of relative frequencies
= sum of all (n) frequencies / number of events =
= number of events / number of events = 1
As a percentage, total relative frequency = 1 × 100 = 100
Answer:
Step-by-step explanation:
The distributive property says that the answer of multiplying two numbers is the same as multiplying the first number by the sum or subtraction of two numbers that result in the second number.
What we have to do is to simpligy the ecuation, this mean, making it shorter.
First we take out the common term of the ecuation: 
.
By distributive property 
then 
.
Answer:
84/2= 42, 42/7= 6, 6/3= 2
84 = 2 x 2 x 3 x 7
