Answer: 2.04
Step-by-step explanation:
2+2=4
4/50 = 2.04
Answer:
(3x-2y=-2)×3
(4x-3y=-4)×2
then minus
x=2
then for y take one equation
3x-2y=-2
6-2y=-2
y=4
Answer: 0.3439
Step-by-step explanation:
Total number of digits : 10
The number of digits except zero =9
The probability of selecting non-zero number :-

Then, the probability that one such phone number , the last four digits do not include any zero:-

Then , the probability that for one such phone number, the last four digits include at least one 0:-

Hence, the probability that for one such phone number, the last four digits include at least one 0 is 0.3439 .
Answer:
Step-by-step explanation:
34 . since the given two figure are similar their corresponding sides are proportonal.
let the missing side be x
take these ratios
15/18 = x/30
do cross multiplication
18*x = 30*15
18x = 450
x = 450/18
x = 25
therefore missing side is 25
35.since they are also similar their corresponding sides are proportional.
let the missing side be x
for this take these ratios
8/12 = 10/x
do cross multiplication
12*10 = 8*x
120/8 =x
15 =x
therefore missing side is 15.
