Answer:
$108.50
Step-by-step explanation:
The total amount earned would be a function of the time spent walking dogs and mowing lawns
8.5(6) + 5.75(10) = 51 + 57.5 = $108.50
Answer:
0.4286 = 42.86% probability that the low bid on the next intrastate shipping contract is below $25,000.
Step-by-step explanation:
A distribution is called uniform if each outcome has the same probability of happening.
The uniform distributon has two bounds, a and b, and the probability of finding a value lower than x is given by:

Uniformly distributed between 22 and 29, in units of thousands of dollars.
This means that
.
(a) Find the probability that the low bid on the next intrastate shipping contract is below $25,000.
This is P(X < 25). So

0.4286 = 42.86% probability that the low bid on the next intrastate shipping contract is below $25,000.
Answer:
x=2
Step-by-step explanation:
We will use the secant-secant Formula:
(whole secant) x (external part) = (whole secant) x (external part)
(1+x+4) * (x+4) = (11+x+1) * (x+1)
Combine like terms
(x+5) (x+4) = (x+12) (x+1)
FOIL
x^2 + 4x+5x + 20 = x^2 + x+ 12x + 12
Combine like terms
x^2 + 9 x + 20 = x^2 + 13 x + 12
Bring everything to the left
x^2 + 9 x + 20- (x^2 + 13 x + 12) = x^2 + 13 x + 12-( x^2 + 13 x + 12)
x^2 + 9 x + 20- (x^2 + 13 x + 12) =0
Distribute the minus sign
x^2 + 9 x + 20- x^2 - 13 x - 12 =0
Combine like terms
-4x +8 = 0
Subtract 8 from each side
-4x+8-8=0-8
-4x=-8
Divide each side by -4
-4x/-4 = -8/-4
x=2
