Answer:
d= 12.2 C= 38.3
Step-by-step explanation:
The radius of a circle is half of the diameter so multiply 6.1 by 2
6.1 x 2 = 12.2 ft
To find the circumference:
C = 2πr
C = 2(3.14)(6.1)
C= 2(19.154)
C= 38.3
Answer:
Step-by-step explanation:
20% of 650
1/5 of 650
130=red
520= not red
Since the ratio is 5:4, they had to multiply 5x11 to get the 55. Now multiply the 4x11 to get 44. When you add the 55 and 44 that's 99 which only leaves 1 for the independent.
Answer:
0.23328,2.4
Step-by-step explanation:
Given that an airport limousine can accommodate up to four passengers on any one trip. The company will accept a maximum of six reservations for a trip, and a passenger must have a reservation.
Assuming independence we can say persons who do not show up is binomial with p = 0.4 and n = 6
a) If six reservations are made, what is the probability that at least one individual with a reservation cannot be accommodated on the trip
= 
b) Expected no of available places = E(x)=
Answer:
.
Step-by-step explanation:
It is given that,
If a figure is dilated, then the image is similar to the figure. It means the corresponding angles of figure and image are congruent.
So, the value of sin(b°) after dilation is equal to the value of sin(b°) before dilation.
We know that,
Therefore,
.
