Answer: A proportion is simply a statement that two ratios are equal.
Example: 2:6 = 1:3
To get that you do this: 2:6 ÷ 2:2 = 1:3
-----------------------------------------------------------
Example 2: 5:10 = 1:2
To get that you do this: 5:10 ÷ 2:2 = 1:2
The shorter one is 13 and the other one is 52.
Answer:
Look down!!
Step-by-step explanation:
Since two points determine any line, we can graph lines using the x- and y-intercepts. To find the x-intercept, set y = 0 and solve for x. To find the y-intercept, set x = 0 and solve for y. This method of finding x- and y-intercepts will be used throughout our study of algebra because it works for any equation.
Ex.
4=2+2
y=4
x=2
Hope this helps!!
Answer:
1/10
Step-by-step explanation:
There are 4 prime numbers from 1 to 10 (2,3,5,7). This makes the probability of getting a prime number as 4/10 = 2/5.
The probability of getting one tail is 1/2, making the proability of getting 2 to be (1/2)^2 = 1/4.
Multiply both probabilities together, and you get 2/5 * 1/4 = 1/10
