Answer:
blue = 110
red = 83
Step-by-step explanation:
110 + 83 = 193
and the blue jar has 27 more coins than the red jar , so this is correct!
Answer:
B
Step-by-step explanation:
First thing to do here is to calculate the z-score
Mathematically;
z-score = (x-mean)/SD
here, x = 130, mean = 120 and SD = 10
Substituting these values
z-score = (130-120)/10 = 10/10 = 1
So the probability we want to calculate is;
P(z ≥ 1) = 1 - P(z <1)
From standard score table, P(z <1) = 0.15866
P(z ≥ 1) = 1-0.15866 = 0.84134

Answer:
(x) = 
Step-by-step explanation:
Let y = f(x) and rearrange making x the subject
y = 5 - 2x ( add 2x to both sides )
2x + y = 5 ( subtract y from both sides )
2x = 5 - y ( divide both sides by 2 )
x = 
Change y back into terms of x
(x) =
The answer would be d
Explanation: the second numbers are both the same, therefore they would be in the same line, and 7-1=6, leaving 6 units between them, I hope this helps :)
