Answer:
D. 54%
Step-by-step explanation:
Find the relative frequency of it landing on heads by dividing 27 by 50, then multiplying it by 100
27/50
= 0.54
0.54(100)
= 54
So, the relative frequency is 54%
The correct answer is D. 54%
Answer:
y < 3/2x - 5/2 or y < 3/2 x - 2.5
Step-by-step explanation:
3x -2y > 5
Solve for y
3x - 2y > 5 when solving a problem with an inequality sign, rewrite the problem and solve with an equal sign and add the equality at the end.
3x - 2y = 5
-2y = -3x + 5
y = -3/-2x+ 5/-2
y = 3/2x - 2 1/2
Now if you have to use the inequality sign, you will use < because the y term was negative and that will change the direction of the inequality sign.
So y < 3/2x - 5/2 or y < 3/2 x - 2.5
Answer:
x = - 1, y = 6
Step-by-step explanation:
Given the 2 equations
y = - 2x + 4 → (1)
y = 6x + 12 → (2)
Substitute y = 6x + 12 into (1)
6x + 12 = - 2x + 4 ( add 2x to both sides )
8x + 12 = 4 ( subtract 12 from both sides )
8x = - 8 ( divide both sides by 8 )
x = - 1
Substitute x = - 1 into either of the 2 equations and solve for y
Substituting into (2)
y = 6(- 1) + 12 = - 6 + 12 = 6
Solution is (- 1, 6 )
Answer:
Slope is 2.
Step-by-step explanation:
Slope is 
if something can be solved to a/b its rational
4/5 is rational already
√4/5 = 2/5 so its rational
√25/4 = 5/4 so its rational
π = is irrational because its 3.14159.....and on and on it can never be rationalized
