Answer: 1:10,000
Step-by-step explanation:
given data:
distance of the nearest star system = 100,000,000
distance to size ration of the sun earth system = 10,000
therefore;
100,000,000 / 10,000
= 10,000
The order of magnitude of the distance to size ratio of the Sun- Nearest Star system is about 1:10,000 times that of the Sun-Earth system.

4 best friends 2 new friends Henry
7 people
2/8 multiplied by 7 or 1/4 by 7
14/8. 7/4
Changed to mixed fraction form
1 6/8. 1 3/4
He would need 1.75 pizzas but since he needs to buy it by the whole, he needs to buy 2 pizzas
We will see that the probability of x taking on a value between 75 to 90 is P = 0.5
<h3>
How to get the probability?</h3>
We know that x is a continuous random variable uniformly distributed between 65 and 85.
This means that the probability that x value y in the range is such that:
1 = P(y)*(85 - 65) = P(y)*20
1/20 = P(y).
Now, the probability of x taking a value between 75 and 85 is:
P(75 to 85) = (1/20)*(85 - 75) = 10/20 = 0.5
And the probability between 85 and 90 is zero (because the maximum value that x can take is 85, so this part does not affect).
Then we conclude that the probability of x taking a value between 75 to 90 is:
P(75 to 90) = P(75 to 85) + P(85 to 90) = 0.5 + 0 = 0.5

Answer:
Yes, the table is proportional.
Step-by-step explanation:
To find out if a table is proportional or not see if they have the same constant of proportionality.
The formula for finding the constant of proportionality is <em>k </em>= <em>y/x.</em>
1/4 ÷ 1 = 1/4
1/2 ÷ 2 = 1/4
3/4 ÷ 3 = 1/4
1 ÷ 4 = 1/4
They all have the same constant of proportionality which means they are proportional.
