Answer:
x - 5y = 30
Step-by-step explanation:
If you subtract x from both equations, you'll get -x. If you divide -5y, you'll end up with 1/5x and 6. The intercept doesn't matter but the slopes are parallel which means they'll never intersect anyway
Rewrite it as
3r-1=8
3r=8+1
3r=9
R= 3
Answer: 0.0107
Step-by-step explanation:
Given : The time for the event for boys in secondary school is known to possess a normal distribution with
Let x be the random variable that represents the time for mile run in its secondary-school fitness test.
z-score :
Now, the probability that a randomly selected boy in secondary school can run the mile in less than 322 seconds is given by :-
Hence, the probability that a randomly selected boy in secondary school can run the mile in less than 322 seconds = 0.0107
