Answer:
I'm sorry but what is the question?
Step-by-step explanation:
Answer:
$24, $30, $36
Step-by-step explanation:
First we need to find the unit rate.
1. 18÷3 = 6
So that means one taco costs $6.
6*4 = 24
6*5 = 30
6*6 = 36
Three angles of the triangle:

3x + 5x + x = 180
9x = 180
x = 180/9
x = 20
Answer:
a. mean = 1000
standard deviation = 4358.9
b. expected value of average damage bar Y = 1000
probability bar y exceeds 2000 = 0.011
Step-by-step explanation:
we have p1 = 95%, y1 = 0, p2 = 5%, y2 = 20000
Mean = (0.95 * 0) + (0.05 * 20000)
= 1000
var(y) = E(y²) - E(Y)²
= we solve for E(y)²
= 0²*0.95 + 20000²*0.05
= 0 + 20000000
then the variance of y = 20000000 - 1000²
=20000000-1000000
= $19000000
standard deviation is the square root of variance
= √19000000
= 4358.9
2.
a. Expected value of average is also the mean = 1000
b. we are to find probability that barY exceeds 2000
= 1000/435.889
= 2.29
1-p(z≤2.29)
= 1 - 0.989
= 0.011
so the probability that barY exceeds 2000 is 0.011
Answer:
9.46 X 10^12 kilometers
Step-by-step explanation:
We will solve this problem by applying s=vt formula.
Here, s= distance
v= 3X10^5 km/s
t= 365.25 days = 365.25 X 3600 X 24 = 31557600 seconds
Now, s= 3X10^5 km/s X 31557600 seconds = 9.46 X 10^12 kilometers
