Answer:

75%

Step-by-step explanation:

You pick a card at random. 6 7 8 9 What is P(not 9)? Write your answer as a percentage. %

Given the following

Total cards = 4 (6,7,8,9)

If the card is not 9, the required card will be (6,7,8)

Number of cards that are not 9 is 3

Probability = expected/total

Pr(not 9) = 3/4

express as percent

Pr(not 9) = 3/4×100

Pr(not 9) = 75%

Hey!~

The simplified version of this equation in slope-intercept form would be y=3x-1.
"M" is commonly used for the slope.
"B" is used for the x-intercept.

In this equation, 3 is the slope (m), and -1 is the x-intercept (b).

Hope this helps and have a great day!

Prime factors of 300 = 22 . 3 . 52
Prime factors of 400 = 24 . 52
Prime factors of 500 = 22 . 53
3. Choose the common and uncommon prime factors with the greatest exponent
Common prime factors: 2 , 5
Common prime factors with the greatest exponent: 24, 53
Uncommon prime factors: 3
Uncommon prime factors with the greatest exponent: 31
4. Calculate the Least Common Multiple or LCM
Remember, to find the LCM of several numbers you must multiply the common and uncommon prime factors with the greatest exponent of those numbers.
LCM = 24. 53. 31 = 6000
