Answer:
140
Step-by-step explanation:
Sum of angles around a point = 360
So, if one angle 8 reflex and measures 220, it’s adjacent side measures.
360-220 = 140.
Hope this helps.
Good Luck
Answer:
5 days
Step-by-step explanation:
Put the given number in the formula and solve for x.
2065500 = 8500·3^x
243 = 3^x . . . . . . . . . . . divide by 8500
log(243) = x·log(3) . . . take logarithms
log(243)/log(3) = x = 5 . . . . divide by the coefficient of x
After 5 days, the number of bacteria in culture will be 2,065,500.
Answer:70
Step-by-step explanation:
Do 21 divided by 3 = 7 . 7 = 10% so 7 x 10= 70
Answer:
If a Poisson process applies, we have the probability that k potholes are find in t miles as:
The probability that no more that one pothole will appear in a section of one mile is P=0.1353.
The probability that no more that 4 potholes will occur in a given section of 5 miles is P=0.0293.
Step-by-step explanation:
We have the rate of potholes:
If a Poisson process applies, we have the probability that k potholes are find in t miles as:
The probability that no more that one pothole will appear in a section of one mile is P=0.1353:
The probability that no more that 4 potholes will occur in a given section of 5 miles is P=0.0293:
Answer:
D. a=1 and b=4
Step-by-step explanation:
x^2-2x+(-2/2)^2 =3+(-2/2)^2
x^2-2x+(-1)^2=3+(-1)^2
x^2-2x +1 =4
(x-1)^2=4
Therefore a=1 and b=4
