Direct Variation - Item 2845

Brums [2.3K]

The equation of direct proportion is y = 62x

<h3>Direct variation</h3>

Two quantities are said to vary directly proportional to each other when an increase in one leads to an increase in the other or a decrease in one leads to a decrease in the other.

Direct variation is given by:

y = kx

where y, x are the variables and k is the constant of proportionality.

The equation of direct proportion is y = 62x

r-ruslan [8.4K]

Answer:

The relative frequency of mammals in the survey is 30%.

Step-by-step explanation:

Relative frequency is the ratio of the occurrence of a singular event and the total number of outcome

Amphibians Insects Fish Reptiles Birds Mammals

12 30 9 25 22 42

Relative frequency = $= \frac{\text{ (number of trials that are successful)}}{\text{(total number of trials)}}$

Total number of wildlife animals = 12+ 30 +9 +25+22+42 = 140

Now the relative frequency of mammals in the survey = $\frac{\text{total number of mammals}}{\text{ Total number of animals}}$

the relative frequency of mammals in the survey = $\frac{42}{140}$ = 0.3

Converting into percentage , we get

= $0.3 \times 100$

= 30 %

Anybody wanna explain this to me?

Vinvika [58]

Sure

Original Equation:
[-5x-16=9x+x-1]

Solve:
[-5x-16=10x-1]

Add (16) to both sides of the equation:
[-5x=10x+15]

Subtract (10x) from both sides:
[-15x=15]

Divide (-15) from both sides:
x=-1
