Answer:
I think you might be able to fill about 3 crates
Step-by-step explanation:
I divided 3,258 by 12 and got 271.5, which will be how many boxes you will have.
Since one crate can hold 100 boxes I separated the amount of boxes needed to be in the crates and got about 3 crates.
Hope this helps
By the order of operation, we first do the operation in parentheses
( 6 * (2 + 15) ) /3 = (6* 17)/3 = 102 / 3
Then we do the division
Answer = 102 / 3 = 34
Hope that helps!
Answer:
(3,5)
Step-by-step explanation:
Mid-point = (1i+2j+5i+8j)/2
=(6i+10j)/2
=3i+5j
=(3 5)
Answer:
0.7477
Step-by-step explanation:
The mean(X) = 25,000 hrs
Standard deviation (σ) = 1500 hrs
The probability that the light bulb lasts more than 24,000hrs is Pr (X˃24,000)
Using Z-scores, Z= (X- μ)/σ
For X = 24,000
Z = (24,000 – 25,000)/1500
Z = -1000/1500
Z = -0.667
From the normal distribution table, Z= 0.667 = 0.2477
Φ(Z) = 0.2477
Recall that if Z is negative,
Pr (X˃a) = 0.5 + Φ(Z)
Pr (X˃24,000) = 0.5 + 0.2477
= 0.7477
Answer:
As few as just over 345 minutes (23×15) or as many as just under 375 minutes (25×15).
Imagine a simpler problem: the bell has rung just two times since Ms. Johnson went into her office. How long has Ms. Johnson been in her office? It could be almost as short as just 15 minutes (1×15), if Ms. Johnson went into her office just before the bell rang the first time, and the bell has just rung again for the second time.
Or it could be almost as long as 45 minutes (3×15), if Ms. Johnson went into her office just after the bells rang, and then 15 minutes later the bells rang for the first time, and then 15 minutes after that the bells rang for the second time, and now it’s been 15 minutes after that.
So if the bells have run two times since Ms. Johnson went into her office, she could have been there between 15 minutes and 45 minutes. The same logic applies to the case where the bells have rung 24 times—it could have been any duration between 345 and 375 minutes since the moment we started paying attention to the bells!
