Answer:
Step-by-step explanation:
Average speed is distance divided by time.
s=(101km)/(1hr)
s=101 km/hr
3/5
= (3*2) / (5*2)
= 6/10
3/5
= (3*3) / (5*3)
= 9/15
Two ratios that are equivalent to 3/5 is 6/10 and 9/15~
The answer is 2 because it’s the same length as the one labeled 2
Answer:
109°
Step-by-step explanation:
X = 38+ (180-38)/2
= 38 + (142/2)
= 38 + 71
= 109°
Answer:
0.06597
Step-by-step explanation:
Given that thirty-seven percent of the American population has blood type O+
Five Americans are tested for blood group.
Assuming these five Americans are not related, we can say that each person is independent of the other to have O+ blood group.
Also probability of any one having this blood group = p = 0.37
So X no of Americans out of five who were having this blood group is binomial with p =0.37 and n =5
Required probability
=The probability that at least four of the next five Americans tested will have blood type O+
=
