The answer for 13 would be 4x-6x=2x
Answer:
look on my brainly, i'm still trying to find this answer.. the weather is messing with wifi/internet
Step-by-step explanation:
Use the slope-intercept form y = m
x + b to find the slope m and y-intercept b
.
Slope:
−
12
/49
y-intercept:
(
0
, 0
)
All of the surfaces are rectangular
Y= -1/3x+2 because The Change in x and the change in y come out to -1/3x then you plug in the coordinates and solve for b. Hope i helped
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
