Answer: <em>Constant of proportionality is the constant value of the ratio between two proportional quantities. Two varying quantities are said to be in a relation of proportionality when, either their ratio or their product yields a constant.</em>
Step-by-step explanation:
To find the constant of proportionality, we use the formula k=y/x. So we have k=20/500 = 0.04.
The equation representing this situation will look like y=kx. Substituting in our value of k that we found, we have the equation y=0.04x.
We can use our equation to find the answer to this problem.
Answer:
0,37
Step-by-step explanation:
It will be easier if we noun the events.
A= Cindi's friend comes to England.
B= New England is mostly cloudly.
We are searching the probability of just A doesn´t happen or just A happens but not B.
The probability of A doesn´t happen is one minus the probability of A:

The events A and B are independent for this reason the probability than both occurs is the product of the probability of each event. It means:

The probability of A doesn´t happen or A and B happen is:

Conclusively we have to rest the probability of A doesn´t happen and A and B happen, but A happens and doesn´t happen and the same time is impossible. For this reason, we have the same result.

Then the probability either Cindi's friend does not come to New England, or she does come but it is mostly cloudy is 0.37
Answer:
x = 7
Step-by-step explanation:
Let
x = the unknown number
double it :
2x
add 11:
2x + 11
I get 25:
The equation is
2x + 11 = 25
2x = 25 - 12
2x = 14
Divide both sides by 2
x = 14/2
x = 7
Answer:
B)2.5
Step-by-step explanation:
When x = 3 the actual = 6
Residual = actual - predicted = 6 - 3.5 = 2.5
