The answer would be .............
y>5
Answer:
2 and 4 are correct
Step-by-step explanation:
1 is incorrect because 4/5 being bigger than 7/10
3 is incorrect because 2/3 is more than 5/9
Answer:
0.20148
Step-by-step explanation:
We solve using z score formula
z = (x-μ)/σ, where
x is the raw score = 230
μ is the population mean = 184
σ is the population standard deviation = 55
z = 230 - 184/55
z = 0.83636
P-value from Z-Table:
P(x<230) = 0.79852
P(x>230) = 1 - P(x<230) = 0.20148
Therefore, the probability that the eye contact time is greater than 230 seconds is 0.20148
Answer:
Orange = 12
Grape = 15
Cola = 23
Step-by-step explanation:
Turning this into equations you can give each soda a variable
Cola = C | Grape = G | Orange = R
Then you get:
8 + G = C
R + 3 = G
C + G + R = 50
We want to get a variable all by itself in an equation so first I'm going to put the second equation (R + 3 = G) in the first (8 + G = C) by replacing the G to get
8 + (R + 3) = C Combine the variables 11 + R = C and put that new equation into the last equation
(11 + R) + G + R = 50
Now plug our original second equation (R + 3 = G) into our third to get
(11 + R) + (R + 3) + R = 50
Combine and get
14 + 3R = 50 Subtract over the 14
3R = 36 Divide by 3
Orange Sodas = 12
Our new 3rd Equation is now: C + G + 12 = 50, subtract over 12 to get
C + G = 38
Plug either equation 1 or 2 into that one, I'll do 1
(8 + G) + G = 38
8 + 2G = 38
2G = 30
Grape Sodas = 15
Now our 3rd equation is C + 15 = 38, subtract over 15
Cola Sodas = 23
Orange = 12
Grape = 15
Cola = 23
12 + 15 + 23 = 50
Answer:
a= $10.00
Step-by-step explanation:
It's very simple. Move /8 to the other side of the equation. It should give you $1.25 x 8. Solve the multiplication and you should get $10.00.
If I didn't make my explanation clear enough, please comment. I sometimes don't even explain myself very well.
