A proportion of a group or an amount is a part of it or a portion or part in its relation to the whole

I put it into simpler terms.

The odds that it will snow tomorrow are 9 to 6. What is the probability that it will not snow tomorrow?a) 0.1818

kolezko [41]

Answer:

a) 0.1818

Step-by-step explanation:

Given that:

The odd that it'll snow tomorrow is 9 to 6

The probability that it will snow tomorrow $=\dfrac{9}{9+6}$

$=\dfrac{9}{15}$

= 0.6

The probability that it'll not snow tomorrow $= 1 - \dfrac{9}{15}$

$= \dfrac{15-9}{15}$

$=\dfrac{6}{15}$

= 0.4

Let assume that the odd that it'll snow tomorrow is 9 to 2

The probability that it will snow tomorrow $=\dfrac{9}{9+2}$

$=\dfrac{9}{11}$

= 0.8181

The probability that it'll not snow tomorrow $= 1 - \dfrac{9}{11}$

$= \dfrac{11-9}{11}$

$=\dfrac{2}{11}$

= 0.1818

I need help with this one

artcher [175]

Answer:

r = I/P*t

Step-by-step explanation:

So I dont know how to explain it but to show you how to do it.

I = Prt

Divide both sides by Pt to get r alone

$\frac{I}{Pt} = r$

Therefore your answer is r = I/P*t

Hopes this help :)

16 factory workers made 40 pieces in a certain amount of time.

qwelly [4]

a) The quantities vary directly

b) The constant of variation is 2.5

Step-by-step explanation:

Lets us revise the direct and inverse variation

If y varies x directly, then y = kx, that means the ratio between them is constant ( $\frac{y}{x}=k$ ) , they increased together and decreased together, k is the constant of variation
If y varies x inversely, then yx = k, that means when x increased y must be decrease ( $y=\frac{k}{x}$ ) k is the constant of variation

∵ 16 factory workers made 40 pieces in a certain amount of time

- If the number of worker increased, then the number of pieces

increased in the same certain time, if the number of worker

decreased, then the number of pieces also decrease in the

same certain time

∴ The the number of workers and the number of pieces produce

vary directly

∴ Number of pieces produced = k × number of worker

a) The quantities vary directly

∵ The number of worker = 16

∵ The number of pieces produced = 40

- Substitute these values in the equation of variation above

∴ 40 = k × 16

- Divide both sides by 16

∴ k = 2.5

b) The constant of variation is 2.5
