Answer:
x=1/3,y=3
Step-by-step explanation:
y=7x+6_____equation1
5x+y=2_____equation2
substitute y into equation 2
5x+7x+6=2
12x+6=2
12x=2-6
12x=-4
x= -1/3
substitute X into equation 1
y=7x+6
y=7(-1/3)+6
y=-7/3+6
y=9/3
y=3
1/10 chance on winning with 1 ticket...so winning with 4 tickets =
1/10 * 1/10 * 1/10 * 1/10 = 1/(10^4) = 1/10,000
Answer:
- <u>$45</u> (with the assumption made below)
Step-by-step explanation:
The equation is garbled; thus, to explain you I will assume the equation is
Where:
- R(s) is the revenue in dollars, as a function of the number of seats occupied.
- s is the variable that represents the number of seast occupied
- 14 is the rate of change of the revenue per seat occupied (the price of a ticket).
- -325 is the fixed cost of the theater for a performance (the amount of money the theater will lose if none seat is occupied).
Thus, you can predict the revenue when 70 seats are occupied by substituting s with 70.
- R(70) = -325 + 980 = $655
The <em>residual value</em> from a prediction is equal to the real value (observed value) less the preducted value:
- Residual = real revenue - predicted revenue
- Residual = $700 - $655 = $45
Answer:
12.6 inches
Step-by-step explanation:
-The distance covered in one revolution is equivalent to the circumference oif a tire.
#We calculate the Circumference of A:
#We then calculate the circumference of B:
-A has a larger circumference than B and the difference is :
Hence, Tire A covers 12.6 inches more than B after one revolution.
|-10 - 3|
Subtract.
|-13|
Simplify:
13
The 'bigger' the negative numbers look, the smaller they are.
Therefore, Option D is correct.
5.1, -3.6, 0, -2, -1.1
Arrange from least to greatest:
-3.6, -2, -1.1, 0, 5.1
So the middle number is -1.1.
