Equation:
65(6) + 4 = 404 or 65x + 4 = 404
Answer:
6 days
Step-by-step explanation:
First do 404-14 to get 390
then do 390 divided by 65 to get 6
I can understand why it might be tough, so I'm here to help.
Translation is as simple as moving the points as told.
For example, do you see where point T currently resides? From there you'd move it 4 units to the left and 5 down, where it'd end up at (-4,-3). Now do the same for every point.
Point T would end up at (-4,-3)
Point S would end up at (-2,-2)
Point R would end up at (0,-3)
Let the time taken to finish the test be x.
P(50 < x < 60) = P(x < 60) - P(x < 50) = P(z < (60 - 60)/10) - P(z < (50 - 60)/10) = P(z < 0) - P(z < -1) = P(z < 0) - (1 - P(z < 1)) = P(z < 0) + P(z < 1) - 1 = 0.5 + 0.8413 - 1 = 0.3413
4z+6.1≥43.7-4z
add 4z on both sides - 8z+6.1≥43.7
subtract 6.1 on both sides - 8z≥37.6
divide by 8 on both sides - v≥4.7
Answer:
$1.25
Step-by-step explanation:
There is a lot of unnecessary extra information we can ignore here. Simply divide the amount collected on any given day by the number of snacks sold.
53.75 / 43 = $1.25
Double check via another day:
45 / 36 = $1.25 ~ yup!
