Answer:
0.07
dollar per minute
Step-by-step explanation:
Given the charging formula :
C(n) = 13 +0.07n
n = number of minutes talked, and
C(n) = monthly charge, in dollars
The slope is the change in amount charged per change in the number of minutes talked.
Also, from The slope intercept equation :
y = mx + c
Comparing the equation :
0.07n = mx
m = 0.07
Since, The slope is the change in amount charged per change in the number of minutes talked.
Amount charged in dollars, talk time measured in minutes ;
Unit = dollar per minute
Answer:
x = 26
Step-by-step explanation:
The midsegment is parallel to the side KM and half its length, thus
KM = x = 2 × 13 = 26

<span>The probability that a house in an urban area will develop a leak is 55%. if 20 houses are randomly selected, what is the probability that none of the houses will develop a leak? round to the nearest thousandth.
Use binomial distribution, since probability of developing a leak, p=0.55 is assumed constant, and
n=20, x=0
and assuming leaks are developed independently between houses,
P(X=x)
=C(n,0)p^x* (1-p)^(n-x)
=C(20,0)0.55^0 * (0.45^20)
=1*1*0.45^20
=1.159*10^(-7)
=0.000
