Answer:
B. x<27
Step-by-step explanation:
300-165=135
135/5=27
Union = {0,1,4,8,10,16}
Intersection = {4,16}
To solve the inequality -25 > -5(x + 2.5), first multiply -5 by the number and variable in the parentheses.
-25 > -5x - 12.5
Now add 12.5 to both sides of the equation.
-25 + 12.5 > -5x - 12.5 + 12.5
-12.5 > -5x
Now divide -12.5 by -5 to get the answer.
-12.5 ÷ -5 is 2.5
You would think the final answer is 2.5 > x, but that is not true because -5 is negative and when a negative number is divided to both sides of an inequality, the sign gets flipped.
So, the real answer is 2.5 < x, or x > 2.5.
Answer:
a) 3/13
b) 1/2
Step-by-step explanation:
a) In a deck of 52 cards there are 4 Kings, 4 Queens and 4 jacks. So the probability of drawing those cards is (4+4+4)/52 = 12/52 = 3/13.
b) 1/2 because the numbers greater than 3 on a dice is 4, 5, and 6 which is half of the available options.
