Answer:
300
Step-by-step explanation:
Sum the parts of the ratio : 3 + 2 = 5 parts
Divide the number of appointments by 5 to find the value of one part of the ratio, that is
= 100 ← value of 1 part of the ratio
The mums consisted of 3 parts, hence
3 × 100 = 300 ← appointments with mums
Answer:
0.025
Step-by-step explanation:
-This is a conditional probability problem.
-Let L denote lens defect and C charging defect.
#We first calculate the probability of a camera having a lens defect;

#Calculate the probability of a camera having a charging defect:

The the probability that a camera has a lens defect given that it has a charging defect is calculated as:

Hence, the probability that a camera has a lens defect given that it has a charging defect is 0.025
Malcolm maximum speed is 200 km/h and Ravi maximum speed is 320 km/h
Step-by-step explanation:
Lets assume Malcolm maximum speed to be M km/h and Ravi maximum speed to be R km/h
Average of their maximum speed is; (M+R)/2 =260 km/h
This can be simplified to M+R= 260*2
M+R = 520.......................................(I)
When Malcolm's speed is doubled,
2M=R+80 km/h ----------------------(ii)
The two equations are;
M+R = 520 ------ M=520-R ----(i)
2M=R+80 ---------------------------(ii)
Replacing M with (i) above
2M=R+80
2(520-R) =R+80
1040 -2R =R+80
1040-80 = R+2R
960 = 3R
960/3 =R
320 =R
M+R =520
M=520-320 =200
Malcolm maximum speed is 200 km/h and Ravi maximum speed is 320 km/h
