Answer:
Step-by-step explanation:
Distance=400+200=600km
diplacement=x 200-0km=200km
total distance travelled=400+400=800km
No because 9/1,000 in decimals would be 0.009 because if the number was a 3 number then it would go in the tenths
Estimate of 2854 = 3000
so 3000 times 9 = 27000
Answer:
The answer is A
Step-by-step explanation:
A because it's simply adding by 4 on the right-hand side.
Answer:0.8413
Step-by-step explanation:
Mean= 188, Std Dev. =20.8, Z=(x-mean)/Std Dev
P(X less than 167.2)= P(Z less than (167.2-188)/20.8)
=P(Z less than (-20.8/20.8))
=P(z less than -1)= P(Z less 1)
The value of 1 in the normal distribution table is 0.3413
So we add 0.5 to 0.3413 =0.8413
