Answer:
y = x + 1
Step-by-step explanation:
The line y = x goes through the origin, and forms a perfect 45 degree angle with the x axis.
This is that same line, moved upward 1 unit, so the y value comes out 1 unit more.
Also, in y = mx + b form (slope-intercept form), we see slope m = 1 and y-intercept b = 1, so
y = 1x + 1 = x + 1
y = x + 1
Answer:
I'm assuming it would be 3 hours
Step-by-step explanation:
It would be 3 hours because after three hours, the candle that can only burn for 3 hours will have burned out. This leaves the candles that can burn for 4 and 5 hours. I guess if you want to get really specific you could say 3 hours and 59 minutes but I'm not totally sure how your teacher wants the answer
Answer: z= -1.636
Step-by-step explanation:
When population standard deviation is known, then the test statistic is given by :-

, where
= sample mean,
= population mean, n=sample size ,
= standard deviation
As per given,

Hence, the e test statistic to see whether the candy bars are smaller than they are supposed to be : z= -1.636
