Subtract 33 from the both sides of the equal sign
Multiply the both sides by -3.5
Now X Equals...
Answer:
$0.68
Step-by-step explanation:
To find the original price of the bracelet, write a proportion. $0.72 is the amount after a 6% tax rate. This means you paid 6% on the original price.
Find y by cross multiplying numerator and denominator of each fraction.
0.72(100) = 106y
72 = 106y
0.679 = y
0.68 = y
Answer:
A
Step-by-step explanation:
Rectangle:
L x W = area
13 x 9 = 117cm
Triangle:
L x W/2 = area
11 x 5 = 55
55/2 = 27.5
117 + 27.5 = 144.5cm²
Answer:
45.12%
Step-by-step explanation:
We have that l = 50
The probability density function of the exponential distribution is:
(1 / l) * e ^ (x * 1 / l) l> 0
f (X = x) = 0 otherwise
in this case X would come being the probability the road in 30 minutes or less to pick-up the children to go to school, it would come being:
P (X <= 30) = integral from 0 to 30 [1/50 e ^ (x / 50) dx]
It is integral as a result:
P (X <= 30) = (1/50) [e ^ (- x / 50) / (-1/50)]
We evaluate x = 0 up to x = 30
P (X <= 30) = (1/50) [e ^ (- 30/50) / (-1/50)] - (1/50) [e ^ (- 0/50) / (-1 / fifty)]
P (X <= 30) = -0.5488 - (-1)
P (X <= 30) = 0.4512
Therefore the probability is 45.12%
